Hi guys! I am unsure about overclocking RAM and would like to ask for some opinions on it. TLDR: Bolded the questions that I have, sorry for the wall of text... I recently upgraded my pc, more specifically got a Ryzen 5 3600, 32GB G.Skill Ripjaws V Black 3600mhz (F4-3600C16-16GVKC and chip type Hynix DJR) and a MSI B450 Mortar max. I reused my PSU and GPU and overclocked CPU to 4.3Ghz all cores @1.25V (I am going for daily stability while being safe, online people say more than 1.25V on CPU will break it eventually, so even though I initially went higher OC, because of the volt limit, I won't OC the CPU any more), my GPU was OC beforehand, and now I am trying to max out the ram. There are so many guides conflicting online regarding RAM OC though that I am very confused. Here is my thought process: Since my ram is already at 3600Mhz + the Ryzen infinity fabric 1800, the only thing I can work with is voltage and timings. I went up to 1.392V (I set it to 1.380V, my Mobo sets it to 1.404V anyways; online people suggest is OK to go even higher, but since I am not going past 3600Mhz, only tighten timings I don't see why to go any higher voltage) I then used dram calculator, which is complete shit for me, even at safe presets suggestions for timings, so I went in myself and started tightening the timings one by one. I understand from reading online that some timings are formulas which depend on others though I only saw conflicting info and decided the best way would be to start with primary timings as low as they can be, then move to secondary timings etc. I use memtest bootable USB + 20 reruns overnight to declare a given OC stable. So far I these are my timings: ORIGINAL XMP values: 16-19-19-39 CURRENT OC values: 15-18-19-28 (CL-RCD-RP-RAS) CR - command rate 1T CL - trying to go 14T not stable RCD - my motherboard shows me two values for this one, one for write and one for read, one of them I got to 17T, while the other to 18T, I forget which one is which at the moment but do they have to be the same values? RC - original XMP value, trying to go 18T not stable RAS - here people say its some sort of formula between two or more values, I so far was able to go from original XMP value 39T to 28T, which breaks any of the formulas I found online, does that matter? I intend to try 27T, 26T etc. till I see the lowest stable one. After I am done lowering/understanding if my current values are any good, I will go to sub-timings lowering one by one to the maximum stable. Is my thought process OK? Is there anything that I am missing / misinterpreted from what I understood from 1020430 different online OC guides? Are there any formulas indeed for the primary timings that I should follow? Are there any formulas for secondary timings that I should follow/ order of importance to lower first for secondary timings? Or can I just go one by one lowering to last stable T value? Does it help to try and tighten/lower VDDG and cLDO voltages or auto is OK? Ryzen dram calculator has termination block and CAD_BUS block ohm values, why is that? does it help for me to eventually tighten those? if so, lowering or upping the values?

Hey all, i've got interested in overclocking my cpu to get some better gaming experience. I've watched the tutorials on the channel and got to the results of 4,3GHz@1.225V on my i5-4670k. There are several different questions now. 1. I've tested the system stability for 120 minutes with Aida64, half an hour with prime95 small fft v266 and played Black Desert Online and Overwatch several hours straight without any crash. what i noticed is, that the VCore gets pulled up to 1.3V sometimes while playing. I have set adaptive Voltage with LLC on "Regular" (Asus z97-k Motherboard). Q: is 1.225 / 1.3V reducing the lifespan of the cpu already? if yes, by how much? is there anything to eliminate the 1.3V? Also about the temperatures, as i have a sh**** case with some old case fans, the airflow isnt rly that good. so the temperatures whith the benchmarking (Aida64) got me around 70°C core temperature and close to 50°C cpu temp. While playing i got temps of mostly 70-80°C Core temp. The Cpu sensor says its at about 60°C while playing. I'm cooling with a Katana 4 Air cooler. Q: are these temps to high? do they reduce the lifespan of my cpu, or by how much do they do? should i better reduce the clocks to be able to apply lower vCores? 2. While i was in my Bios i had a look at my Ram bec. everywhere i read to take into consideration of overclocking my ram for more performance. So i have a set of old ram, and a set of kinda new (2years or so) ram. i have 2 of each in the slots. https://www.kingston.com/datasheets/KHX1600C9D3_4G.pdf http://www.kingston.com/datasheets/khx1600c10d3b1_8g.pdf Q: As the rams have different specs. how should i set my rams? the one module states its tested for 1.5V, but i ran it with 1.65V bec. of the xmp profile that was loaded. My system is actually running with 1.65V and 9-9-9-27 timings for these 2 years without any problem. I just thought the 8GB rams would get hot, to hot, or anything bec. of the 1.65V? should i better take out the 2x4GB? should i rather set them to 1.333GHz with these timings? or let them stay at 1.6GHz with some higher timings? What should i do about the Voltages? do they run to hot with 1.65V? whats the best method to check that? do rams also have thermal safety shutdown or will they just break if they run to hot? (the html is a list of cpu/ram information in my system) If you need any additional information, i will reply as fast as possible. Thx, Tia tia - Kopie.HTM

ASUS ROG STRIX Z270H Corsair Vengeance LPX 3000MHz DDR4 Looking to play around with my RAM timings. Corsair advertises timings of 15-17-17-35. In ASUS ROG BIOS I can find values for the first, second and fourth timings (CAS Latency, RAS to CAS Delay and RAS ACT Time) but cannot find where the third number is. Searching online shows me that it should be the tRD value, but I only see that in the BIOS under Third Timings section, and there are a bunch of tRD value to be seen (tRDRD_SG, tRDRD_DG, tRDWR_SG, etc etc). Any idea what I'm missing? Photos of all of my DRAM Timings settings in the BIOS (sorry for quality): http://imgur.com/a/BJog6

So, for my new Ryzen 1800x build, I went with Corsair 2 x 8GB DDR4 300MHz RAM (CMK16GX4M2B3000C15W). So far, I haven't been able to get it stable at 2933 (sometimes it will POST, other times it gets stuck and resets the RAM). However, I'm not terribly concerned about that, as I'm hoping a future BIOS update will fix it. My specs are in my profile, but I'm running the Gigabyte GA-AX370-Gaming K7 with the F3b BIOS (latest official version). Here's the odd part. I've got it running stable at 2666MHz, which is fine for now. I manually set the voltage to 1.35 and the clock multiplier to 26.66. I then set the timings to 15-15-15-15-36 for both channels A & B (even though I'm only running 2 sticks). This works and everything is completely stable, however I'm getting conflicting information from Windows. When I run the CPU-Z version from Gigabyte, it tells me my RAM is running at 16-15-15-15-36. I've attached pictures of the BIOS settings, as well as a screenshot of the CPU-Z report. I'm not so much concerned about the slower CAS timing (though I would like to fix it), I'm more interested in why I'm getting conflicting data. Any thoughts?

Hi guys, I'm having some problems with my new Ryzen system that I put together a few months ago My current specs are: Ryzen 5 1600x corsair dominator platinum 2x8Gb (CMD16GX4M2B3000C15) MSI R9 390 MSI AMD AM4 B350 Gaming Pro Carbon Ryzen Corsair HX750i CPU and GPU are watercooled So my problem is that I can't figure out a way of having a stable system with my memory at more then 2133Mhz when the memory should be able to handle till 3000Mhz. I already tried both XMP profiles with 1.35V on the memory and can't even pass the 1min test on Aida64. i tried several of the different profiles available on the on my MSI board (Memory Try it!) and none gave me a stable machine. Tried also leaving the voltage at 1.35 setting the timings has recommended by corsair (15-17-17-35) but not even 2400Mhz remains stable, aida64 runs for a couple of hours with no problems, but after some heavy loads (like playing a game) I get random crashes, like webpage losing content, blue screens, ... Has anyone had similar issues like this? or does anyone that has an identical set of memory that was able to find the sweet spot for those timings? Thanks

Hello, I have a quick question that I've tried finding a good answer to, but I'm not finding what I'm looking for. I have a friend that is upgrading the RAM in his computer. I'm not sure what exactly he is running, but it's something relatively modern, and the RAM slots are coded in 2 different colors (indicates dual-channel to me). He is currently running a 4GB stick (PC3-12800 with timings 10-10-10-27) and a 2GB stick (PC3-12800 with timings 11-11-11-28). I attached CPU-Z screenshots of those modules. He has these in the same color slots and I understand that in this configuration, it will use the timing of the slowest module. He is planning to get another 4GB stick (PC3-12800 with timings 10-10-10-27, link http://www.frys.com/product/7795018) and is planning on matching it in the same channel as his other 4GB stick and moving the 2GB stick (with the slower timings) to the other color slot. He doesn't have the money to buy a full kit at the moment and is making do with what he can find. I'm wondering if matching the timings of the new stick to the old stick in the same channel will allow one channel to run at the faster timings (10-10-10-27) while the other channel runs at the slower timings (11-11-11-28), or if all of the RAM will still run at the slower speed because of that 1 slower module. I appreciate any information you guys can give me. Regards, Vincent

In this thread I will provide some step-by-step instructions that may allow you to get your memory up to speed if you haven't been able to. Introduction: So, one thing that has bugged me is my pricey Corsair Dominator Platinum 3200mhz 2x8 gb kit wasn't able to get up near 3200 without a Bclk increase and 3200 was not possible without errors in stress testing. But for most motherboards the AGESA 1.0.0.6 updates have opened up a lot of user tunability to memory parameters. Using Thaiphoon Burner, AIDA64, or even your BIOS reports on SPD information, you can read the XMP data from the sticks and insert those timings into the BIOS. For me this has resulted in solid, error free memory at the rated speed of 3200 mhz without Bclk increase. I'm on the ASUS Crosshair VI mobo with the latest 1403 beta BIOS. A Note to Corsair Users (others can skip this): If you use Corsair memory you are not feeling the love -- almost nobody talks about how to fine tune these sticks properly yet. And you may be confused when some folks with the "same" memory as you have have success and you don't. So let's address that since I have Corsair sticks and that confused the heck out of me. Something about Corsair: they market the same product with different chips in order to hit demand. Corsair sells more memory than anyone else. Part of knowing what to do is knowing what you have and that can be an issue. One thing you will notice is that Corsair kits often have a "version number" attached and that's an indication of what's used. You don't see this so much on other products that tend to have only one hardware type per SKU. Mine say "Ver. 4.24" and you can find that on the DIMM itself as usually the box as well. Where it's NOT told to you is in the listing to buy the memory. Mobo manufacturers often have a "qualified vendor list" or QVL (or something like that) to tell you what to buy for best results. For the Corsair memory, at least on the ASUS Crosshair VI QVL, it mentions a version for the Corsair parts -- and only for the Corsair parts because they seem to be the only ones who work things this way. It allows them to make large volumes of memory using a variety of DRAM suppliers so I see why they do it. However, that version system makes it very hard to buy compatible Corsair memory unless you're looking at it in a store, get lucky, or some vendor I haven't seen yet TELLS you what version the memory is -- which they generally DON'T. Dominator Platinum have apparently used both Samsung and Hynix chips, but the ones I'm familiar with use Samsung D-die, E-die or B-die chips. The E-die versions are dual-rank (due to lower density) and harder to get "up to speed". What I'm Running: I'm using CMD16GX4M2B3200C16 version 4.24 which are Samsung, dual-rank, E-die. Version 4.31 of my kit are supposed to be B-die. I'm using a locked 100 mhz Bclk, 1.4 volts on running and boot, 1.15 volt SOC and 1.05 volt SB settings. I'm using a p-state overclock to 3800 mhz and hitting nearly 1.4 volts because my chip sucks. But it's still making me happy with what it can do so no harm no foul. With the p-states it's not running at those volts all the time. Running CMD 1T (on auto), manually set 68.6 ohm ProcODT and "Gear Down" is "Enabled" on the Auto setting. Memory Specification -- It's More Than You Think: Also, keep in mind that technically ANYTHING over 2133 mhz is an "overclock". Intel did a good job with their XMP profile and memory training systems which result in most all the sticks (including Corsair variations) "just working". AMD hasn't gotten that far yet. XMP stands for "eXtreme Memory Profile" and it describes some additional parameters that are needed to hit your "rated overclock". So lets say you buy 3200 mhz, 16-18-18-36 memory and they give you a rated voltage. You THINK that's all you need to get an overclock. You believe those timings "specify" your memory. But there are other parameters "hidden" in the Intel XMP data on the DIMM's "SPD" flash memory that defines additional critical timing parameters that should be in place before training. Training is basically running the memory through some test sequences and setting other technical-and-only-to-be-grokked-by-the-priesthood timings to fine tune it. Training is not an exhaustive test though. Many if not most Ryzen mobos even at AGESA 1.0.0.6 do not appear to be using the XMP timings, but are substituting their own defaults from a table of some kind. What you end up with does not match the XMP on many memory sticks. The result is frustration. What this means is that for a given clock speed, memory training will not result in a satisfactory memory overclock and/or stability. Intel made memory folks specify those parameters for a reason -- and AMD and a lot of mobo makers are not yet following suit. Example: Attached below is the complete specification of my memory stored in a flash area on the DIMM itself. Note the "Extreme Memory Profile v2.0" at the bottom. and the line I've highlighted. That line gives a "complete" memory specification for the stick. Besides the standard 16-18-18-36 timings, it specifies values for these items -- and you can look up what they mean: tRC tRFC1 (sometimes simply "tRFC") tRFC2 tRFC4 tRRDL tRRDS tFAW In practice, all those extra timings need to be set BEFORE training. The basics of what I did to get my memory up to speed is to fill that information in by hand in the BIOS and Bob's-your-uncle, my memory worked. I followed the insanely long Crosshair VI overclocking discussion on overclock .net (over 2000 pages, yikes!) to learn from masters how to further tweak for best performance -- a time consuming occupation I'll tell you. I'll share some of what I learned later. So, that's a start and an introduction and in my next post we'll deal with the step-by-step process.

I changed my memory timings using Polaris Bios Editor and flashed it using ATIflash. All I did was copy paste the 1750 value into the 2000 value. The GPU is not bricked, I can easily flash the original BIOS back and everything works. I have tried resetting the CMOS. Any suggestions?

I'm building a new PC soon and I'm undecided between a few RAM options. The usage is about 50% gaming while streaming, 25% video editing in Sony Vegas / Premiere, 15% 3D modeling in Maya, 10% Photoshop/Illustrator. Motherboard would be an ASRock Z170 Extreme4 running an i7-6700k. The kits I'm looking at are Corsair LPX Vengeance 16GB x 2 sets of either: - CMK32GX4M2B3200C16 (3200Mhz 16-18-18-36) for ~200$ - CMK32GX4M2B3000C15 (3000Mhz 15-17-17-35) for ~200$ - CMK32GX4M2A2666C16 (2666Mhz 16-18-18-35) for ~145$ Note that I'm in Japan and the prices are approximations from yen. I've read about the topic a bit, but I'm still confused on how much do RAM frequency and timings impact daily usage. Do the higher frequency and lower latency justify a 55$ price difference? Would I actually benefit from picking the higher priced kits? tl;dr Which one do I buy?

I'm falling down a rabbit hole of RAM options. Right now I have an intel CPU but I will be upgrading to a Ryzen 5 3600 soon so I need to take RAM into consideration. I'm looking at 2 sets in particular: G.Skill TridentZ 4x 8gb 3600 CAS 19 $189 (sale) G.Skill TridentZ 2x 16gb 3200 CAS 16 $169 (sale) I know Ryzen likes 3600 better, but considering I'll be running in dual channel, I wonder if I'll take a performance hit with 4 sticks as opposed to 2. I'll be getting a Gigabyte x570 Aorus Elite if that matters. My use case leans more towards video editing/rendering than gaming, so I also wonder if having a CAS of 19 even matters for hyperthreaded workloads. I can probably tighten the timings of the 3600 RAM, but with 4 sticks it might be more difficult. Plus I read that it puts strain on the memory controller? I can't really find any information on this besides people saying it on forums. Then again, x4 RGB vs x2 RGB.. XD Please help... my brain hurts >_<

What should be the optimal memory timings to consider when buying DDR4 RAM modules ?

Hello, I built a new PC recently and have had a bad time trying to get my Ram running correctly. I reset motherboard back to defaults, and if I set XMP i fail AIDA64 memory tests almost immediately. I even RMA'ed my ram and have the same issue. Specs: 9700k MSI z390 gaming edge 32gb ballistix 3200 ( https://www.newegg.com/ballistix-32gb-288-pin-ddr4-sdram/p/N82E16820164140?Item=N82E16820164140 ) I've tried upping voltages to 1.4 and 1.45 on DRAM, fiddled with SA and IO voltages, but it seems no matter what I do AIDA64 fails quickly. The only thing I can think of is I've seen people saying ram can learn the timings wrong. I don't know much about timings except the basics. Here is my stock timings vs XMP Any ideas? I've been reading posts by @MageTank but I can't really tell if something is completely out of whack.

Hi guys I'm about to buy some new RAM for my Ryzen 5 1600 system, and I can't seem to find the difference between these two kits One is a little bit more expensive but I can't seem to figure out why Why is one more expensive than the other? https://tweakers.net/pricewatch/786133/corsair-vengeance-lpx-cmk16gx4m2z3200c16.html https://tweakers.net/pricewatch/459273/corsair-vengeance-lpx-cmk16gx4m2b3200c16.html

I have a question. In bios I set my dram to stock 3200 14.14.14.34, but ryzen master and cpu-z both show my timings are at 16.16.16.(can't recall the last number but it was higher than 34) could they just be showing incorrect readings? Is there another software I can check it on, or do I need to do something different in bios? They both show my speed to be correct. Also, how I set in bios was I manually set the speed to 3200, then opened up docp(I think that's the acronym) to apply the xmp profile, there was only one available 3200mzh 14.14.14.34. I'm using trident z neo with stock ratings at that speed and timing. Ryzen 5 3600, rx590, trident z neo 3200 cl14 (14.14.14.34), Asus rog crosshair viii hero x570

Hi All! I have a query regarding RAM latency on a friends 2700X build His specs: Asus Prime X470 board Ryzen 2700X Corsair Vengeance 16Gb kit He's recently bought a new graphics card (Second hand 2080ti) and he's not quite getting the performance he was expecting out of it. I've already explained that the 2700X isn't the 'Best' CPU for that card and he understands that but running a few test between his computer and mine we've noticed some differences between the two systems. I'm still running my 6600K in a Z170 board. The biggest difference is he's getting some serious latency in Passmark Mem test compared to my own system with his RAM in it. Here's the pics: This pic shows what he is getting on his system in Passmark The following Pic show what i'm getting with his RAM kit in my PC Now, all either of us are doing with timings is turning on XMP/DOCP in our bioses. No other timing are being changed. The reason I'm asking this is to find out if this is normal for a 2700X really or if i've got to tweak the timings in his bios or not Thanks in advance for any information Chunk

Ryzen 3000, I will start by saying me being excited about the new 3800x is an understatement. On to the real question. In terms of how ram works, if your goal is run at 3733mhz speeds with as tight of timings as you can get. Does it make any theoretical sense to buy a 3800 or 4000 speed kit and only run it at 3733. Would doing so allow your ram to have better timings then a normally packaged kit sold at 3733 advertised speeds? As for logical reasoning's I have none. Its like the Camaro you just got, I want to make it as fast as possible just because I can.

I have had 1 8GB 2400Mhz corsair vengeance LPX RAM stick for 2 years before finally buying another 8GB 2400Mhz of the same make and model but different color(Previous one was Red this ones Black). I have a i5 7400 and an Asus H110M-CS Mobo. The Mobo was only Two RAM slots so now the 2 8GB RAM is running in a Dual Channel config, as is shown in the Scre enshot But even though its running in Dual Channel config, the speed and other metrics is different for both RAM. So are both of my RAMs running in Dual Channel config?? Or is there something wrong?

Hello fellows, so i lowered my ram timings to 12-14-14-32 and ran memtest64 for 20minutes and it was stable also my ram is ocd to 3333mhz. Could i go lower with the timings if it stays stable and what happens if the timings dont go correctly. Also do i need to touch on voltage? Need tips asap :D Ram: 2x8gb 3000mhz hyperx predator cl 15, 1.35v Mobo: z270 aorus gaming 7 Cpu: 7700k @ 4.8ghz 1.32v

So basically i have 2x16 ddr4 3600 cl18 ram. The Asus X470 Prime Pro only goes up to 3466 speeds. Would dialing back the speeds to 3466 and tightening the timings just be free performance?

So this is all Buildzoid's fault... in a good way, so far. He posted this video: and since it was done with my... well, my exact setup minus the RAM, I decided to give it a try myself. Now before you go "WHY THE..." I'm not pushing anywhere NEAR as hard as he is or as high. I am just very picky about numbers and I very much wanted to see if my RAM could run 4000MHz at decent timings without murdering it with voltage. So, I pretty much started where he started the guide, 1.45V, VCCIO & VCCSA at 1.2V, I let the timings auto, stuck the RAM at 4000MHz, booted up, saw it was at crazy-loose timings (19-22-22 or some crap), rebooted & lowered them, and kept throwing some benchmarks at it while refining things. Right now here's where I'm at, and I have the CPU at STOCK not 5GHz since I wanted to be sure the RAM is the only thing that could possibly be unstable if something fails/bluescreens, and I also have all 4 sticks installed (since he said for this board/setup, it actually is better to have 4 sticks vs 2): And that is at 1.4V on the RAM with the IO/SA still at 1.2V, the majority of those timings are still auto. Also some things in the screenshot aren't quite showing right, my Northbridge/Uncore is at 4.3GHz (stock). Also for anyone seeing rising RAM temps, if you have RGB units, disable the RGB lighting while you're testing things, as that will lead to cooler temperatures (not a huge difference, 1-2C, but still, every little bit helps according to Buildzoid). Couple of questions for anyone that's also been there done that or is doing this, what do you use to test your RAM? Just MemTest, or do you also use Prime95 etc? What timings are you guys running at what clocks, do you have any obvious recommendations where I could improve further? I'm thinking about pushing the tRFC down under 400, but I don't know how low I should be going at this speed. I did try 16-16-16-36 & it booted but I could tell the system wasn't very happy with it right away by the weird results from CineBench & what little else I ran before reverting to 18-18-18. Oh, also, when I say I went deep: I've been at this for like 7 hours lol Hence why I'm not seeking suggestions on what else I can try other than "just lowering the timings by one at a time until it fails"

So i recently just upgraded my CPU, RAM and Motherboard and i bought 2x8gb sticks of G.Skill TridentZ RGB 3200mhz and was about to get another 16gb kit but where i originally bought them from dont have any left in stock and i dont wanna pay 200$ for the kit i can get for 145$-160$. Can i get say 2666mhz from the same brand but manually copy and input the timing in the bios or will that not work? srry if its a strange question.

Hey guys, Planning to upgrade my CPU/Mobo/Ram this black friday and as such, i've started my research. So we can all agree that Ryzen 3 series performs best paired with ram at 3200MHz and CL14 timing, right? The other "more viable" option is 3600MHz CL 14/15, but that's waaaay to expensive around here (im talking 220€+ for a 16GB kit). On the other hand, 3200MHz CL14 is basically non-existent too, the only kit I can find is a really ugly Team Group T-Force Night Hawk Legend RGB kit. So I'm just thinking of getting a set of 3466MHz CL16 Ram, which I can get for around 120€ (16GB) and underclocking it to 3200HMz and tightening the timings. I'd be buying a Ryzen 5 3600 or 3600X - depending on the black friday deals. Here are my questions: How viable is this? Does the motherboard I buy have any influence? (Of course, my desired speed would be supported, thinking of B450 or B550 if it has been released by the time I purchase) Im on a tight budget, around 400€ for the whole thing, so I wanna squeeze the most performance I can from my parts . Any feedback is appreciated. Thanks a bunch!

Ryzen 3000 series cpu DDR4 Memory suggestions. Purchase what you need. The more memory you have (in GB) the more strain on IMC. Is 16GB enough? Yea, probably for most gamers and average users. Get only 2 sticks. Most Dual channel configurations are in slots A2 and B2 AMD DDR4 Clock speed and timing suggestions. (for purchase) 3000mhz - CL 14-14-14 3200mhz - CL 14/16-14/16-14/16 3400mhz - CL 16-16-16 3600mhz - CL 16-16-16 3800mhz - CL 16-16-16 (desired IF 1:1 speed) _________________________________________________________ What to do if my Memory has really loose timings? At the above, you use this for reference. Start small. Work your way up, small increments. If you're going to try 16-16-16 timings, start perhaps at 3000mhz or 3200mhz. tCL -16 tRCD -16 (both channels) tRP -16 Memory Voltage - Most XMP profiles are 1.35v Manually set this. Power Down mode set to disabled. This feature throttles memory voltage at idle states. (instability for o.c.) Gear Down mode (optional) - this disabled allows for odd ram timings There is no need for Gear Down mode, you want nice even timing sets IMC-Integrated Memory Controller IF-Infinity Fabric, always keep linked to memory speed ____________________________________________________________________________ Results. - Yes they will vary. The sweetest spot and Best performance is CL 16-16-16 3800mhz IF linked. 3600mhz is the next best thing. This quick guide is to get you started. There's a lot more to overclocking, I just set this up so that at least you can have better performance than running only 2133mhz (1066 effective) with your Ryzen processor. If your memory and system is only stable at 3200mhz, that's ok. It'll still perform noticeably better than stock 1066 15-15-15. Good luck and have fun. (may add more later - I'm tired. Been a long day) disclaimer, I'm not liable or the forum it's staff and affiliates. you make your own choices to overclock or tweak your system.
