ram Will this ram combination work with XMP?
UberInferno posted a topic in CPUs, Motherboards, and Memory
I've got corsair CMZ8GX3M2A1600C8R x2 Do i need to get the exact same type of ram corsair CMZ8GX3M2A1600C8R x2 Or i could get any type of ram which is 1600mhz and 8-8-8-24? Right now i got 2 of those mixed with samsung cl11 so its running 1600 at cl11. When i remove the samsung sticks i'm able to run xmp 1600mhz 8-8-8-24, otherwise its cl11 and 1600mhz at best. Except of color, is there any difference between CMZ8GX3M2A1600C8 and CMZ8GX3M2A1600C8R? What ram should i get? I want to run 16gb with xmp, at least cl8 1600mhz. -
Hey guys! I want to overclock my (title listed) ram, using a Z390 pro (t-topology) and i9 9900k. I want to know what your settings are or what settings I should shoot for. Id love to tighten timings if possible. Just looking for a baseline/shortcut to avoid hours of headache! Thanks in advance!

So yeah. I mixed two different ram sticks. One is a Crucial Ballistix 8GB 1600MHz and a Kingston HyperX Fury 4GB 1600 MHz Crucial is my original ram stick, it boots up very fast, I also have my OS in my ssd so no problems there. So when I put the other 4GB, the boot up is slower than ever. Any help on this? I searched a few and said that I should fix the timings and stuff. Any help? Thank you in advanced.

Hi, i have DDR4 8GBx2 hyperx predetor running at 2666mhz with i5 8500. current timings 13-14-14-32, as per user benchmark results i get 33GBs memory bandwith on multi core 28GBs memory bandwith on single core 51ns latency. my friend told me to increase timings to get better bandwith but worse latency. is that right? increasing timings gives better bandwith but worse latency and vis versa? which is better for gaming bandwith or latency?

Hi, Currently I have Gigabyte B360M DS3H motherboard with two sticks of ram 8x2=16GB DDR4 Hyperx Predator running at 2666mhz. Userbenchmark shows that memory bandwidth on multi core is 32GB\s only, while the CPU i5 8500 can handle upto 41GB\s, isnt that low (32GB\s)? (screenshot attached) If i bought new two sticks 4x8=32GB, will this increase bandwidth and performance and can my board handle it (below from mobo site), i might need the upgrade as available memory is only 13GB and some multiplayer games can take upto 10GB 4 x DDR4 DIMM sockets supporting up to 64 GB of system memory Dual channel memory architecture Support for DDR4 2666/2400/2133 MHz memory module timings of the rams is 12-13-13-32, that why i have low latency. thanks.

I remember when I overclocked my DDR3 kit, there was a rule where you added up the first 3 timings and subtract by something to get a rough idea of what to change your tRAS to (4th timing) to save time testing. Is there something like that people do for DDR4? Otherwise, I'll just spend more time working the timings and testing I guess. Memory overclocking is so tedious so it's worth asking anyways. -
Does someone know will CL14 vs CL16 make a substantial difference? A 16GB 3200MHz CL16 kit is 150 euro, and the same but with CL14 timings is about 220 to 250 euros. Is it worth the massive price difference? Or should I go to a lower frequency with tighter timings?

Alright, I'm gonna admit that this might fit into the Laptop section, but I'm not curious about the laptop. I'm curios about the RAM. I saw they have some Ryzen machines running 4266MHz RAM and that perked my ears right up. So I decided to look for some Geekbench scores. In so doing I learned that the timings are absolutely stupid (and so is the measured bandwidth). But I couldn't see more than the primary timings that Geekbench reads. LPDDR4X 4266MHz with 40-39-45-90-135 (surprisingly 1T) From what I could find online I think that's running with 1.1V on the DRAM, but I couldn't find anyone actually talking about it online in any forums. Is there anyone here that perhaps has a machine and can tell me all the timings of the kit with something like ZenTimings? https://www.overclock.net/forum/13-amd-general/1740690-zentimings-3.html#post28555146 And just out of curiosity could you run HWiNFO and see if the DRAM voltage is reported in there? But what I really want to see are Aida benchmarks. Is there anyone out there that can help me out? -
Which one do you think will overclock better with a 3900x ? (mobo : b550 aorus elite) Apparently micron is better for ryzen 3000 end b550 mobo ?

My friend and I are trying to see who can squeeze as much performance out of their system as possible, ya know, as kids do these days. We started with manually tuning our RAM. We both have 16-19-19-39 3600MHz kits, but through our OCs we got different results, as you do (both of these were tested with MemTest86 with 0 errors). I got 16-18-17-18-36 (along with a bunch of other things I changed), while my friend SOMEHOW managed a tCL of 13, however most of his other numbers were worse with 13-19-17-19-39. I have come to the lords and ladies of things I don’t understand to ask which one of these is better (and why because yay learning). We are also on Ryzen if that helps because I know it likes good RAM. Thanks!

DDR4-3060 CL14-17-17-39 works fine (maybe) DDR4-3060 CL15-17-17-39 always turn into 16-17-17-39?! DDR4-3060 CL17-17-17-39 always turn into 18-17-17-39?! Why does it refuse to input 15 and 17? Does it hate these numbers? :<

I was using changing DRAM timings in gigabyte aorus b550 elite bios in the tweaker tab and when I checked CPU-Z and Ryzen master my timings did not apply. I did have very aggressive timings so maybe it is not applying them because it is not able to boot. But in cpu-z and ryzen master the CAS Latency is 15 when the RAM default is 16. What is the issue? Thanks

So I kinda tweaked the memory timings on my HTPC. But I didn't run an actual stress test. Instead, my kids pound the machine all day/night. Now my timings have been set up for a few days. And kind of experimenting here..... So what are your thoughts? The PC is used for Multi media, Gaming from light to heavy, and everything in between. Should I still run OCCT linpack for the heck of it? (No reports of unstable system yet) p.s. I'll get some screen shots of the memory set up soon.

So I figured out I accidental purchase z170 memory for my x99 platform long after the 30 day return was here and gone. Since then I've been trying to figure out what timings/speeds to achieve the best performance. I've got my 2x16gb modules at 2400mhz and what I believe the correct timings are, but I get some really odd stuttering which gets worse as I increase the variation on the timings or push my memory overclock. EDIT: Memory in question mobile links for newegg apparently can't be turned into normal links by replacing m. with www. I'm running a 5820k and I'm trying to get everything working so, hopefully, I can get another set for quad channel at some point (I know you're supposed to get it all at once but hey). I can list my timings when I get home from work but I know basically it's 15-15-15-35 1cr and 2400mhz. I can probably recall any timings if anyone needs to know. Just trying to narrow down the cause of an issue I'm having -
Hi friends, I got a new awesome samsung B-die kit (3600 running at 3200 with my ryzen 1700) and lowered timings from CL16 to 14-14-14-28. After doing a memory benchmark in Aida46, the memory latency is about 79ns, is this normal? This is not very fast right? Is there anything I can do to improve this? My mobo is x370 Taichi. Another question about lowering timings, should I reduce the 'bank cycle' timing as well? CPU-Z shows me this: Should I reduce it? If yes to what value? It just looks high to me compared to the other timings.

Hardware: Ryzen 7 1700 @ 3.9GHz Memory kit: Corsair CMU16GX4M2C3200C16. MOBO: Gigabyte Gaming K5 AX370 BIOS: F22 A little bit of context: Since BIOS F5 was released (which was replaced by F10 version, I think) I was able to boot with 3200MHz... In games always after 1 hour or so stutters appeared, sometimes the game crashed sometimes not... even when it was capable to endure AIDA64 & memtest64 tests without prblems but it was never able to endure blend test from Prime95... the higher speed to run my memory kit was 3000Mhz til I found this two videos that helpme a lot: The first one help me a lot to set some extra voltages and to understand what DDRVPP and DRAM voltages does and how they can help to stabilise my system (which it is the reason why my memory kit is runing at its speed) and the second one to improve test results and sometimes to get more stable FPS. (for example on Battlefield 1 in some maps my FPS was dropping til 95 but now the lowest value I have seen is 100 ~ 105). The main reason (apart from that it maybe can help someone else, although there is already a lot of information out there... who kwnos) is to know if someone could help me to know how much I can increanse DDRVPP voltage or how much voltage is considered safe? -My voltages right now: Here you can see a little bit of improvement I can get with some right timings:

I need to boost my ram speed from 1200, to its advertised speed of 2400. I tried doing this in my BIOS, but the bios only allows it to go up to 2000. Fair enough. But it restarts itself 3 times indicating that's it's failing to boot upon that speed. I assume I have to tinker with the timings correctly, but I don't know how to do that. Can anyone help? And if there's a way to allow it to actually reach 2400, can you please tell me how? 2x8GB Corsair Vengeance DDR4 2400MHz -
I have 2 kits of 2x8gb dual channel 3600mhz g.skill ram (model F4-3600C17D-16GTZR) installed in my asus maximus ix hero motherboard with 4 dual channel slots for ram. But I've recently experienced 2 crashes, 1 bluescreen and 1 random loss of display. I'm pretty sure this is because I'm using 2 kits of 2x8gb ram instead of 1 kit of 4x8gb, so the timings arent configured for 2 kits to work together. Does this sound like something that could easily be fixed by reconfiguring the timings? If so, how can i do this? And what should i use for my configuration? If this ends up being a bit too complicated or less reliable than just 1 kit of 4x8, I'm probably just going to refund my 2nd kit while i can and live with 16gb for a while.

So after a few hours of messing around with my new Ryzen 1700X build, I finally got it stable at 3.9GHz and 1600Mhz (DDR-4 3200) for the memory. Unfortunately I can only get the 16GB G.Skill FlareX 3200 kit down to 16-16-16-52 when it's rated for 14-14-14-38. I'm using the Asus ROG Strix X370-F Gaming motherboard. Any suggestions or links to good memory timing guides that won't make my brain hurt? -
Recently started tuning my memory kit I bought when I built my PC. I'm getting some weird results using the DRAM calculator for Ryzen. The timings work and using Prime95 large ffts and haven't had any issues. Memory stats from thaiphoon are below. Along with the current "stable" timings.

Chart: http://i.imgur.com/D4JWHOq.png Coverage: - 800-4500 Mhz (29 speeds) - 7-21 CAS Latency There's a large range of numbers, what's a good response time to look for? Typically anything below 14 is a decent speed. 12-14 is about average for today's standards. Anything near 10-11 or lower is very good. Anything under 10 is phenomenal. You should probably avoid anything above 14. This chart combines the frequency and CL combinations of practically all semi-modern to modern memory modules into a single raw performance number. This number alone doesn't mean much, but it means the world in a relative scenario like the graph above. This graph is useful if you want to compare several memory modules of different frequencies and latencies to find out which is fastest. Sometimes the faster module turns out having a lesser frequency than what you compared it against thus saving you a few monies. It could also be used in the high-end to determine which memory module will have the best performance if you're looking for the best you can get. As an example, let's say you wanted to compare the Kingston HyperX Fury Black 8GB 2133 CL14 against the G.Skill Ripjaws V Series 8GB 2400 CL16 memory modules to see which performs better (frequency and CL go hand-in-hand to determine memory performance). The Kingston stick has a worse frequency, but better CL timings while the Ripjaws stick has a higher frequency and worse CL timings. Without a graph like this, it's hard to tell which would actually perform better and you'd probably just assume it's the one with the higher frequency. Visiting the graph, the Kingston stick has a response time of 13.13 and the Ripjaws stick has a response time of 13.33. So, if you assumed the higher frequency module was faster, you were wrong; the Kingston module is slightly faster even though its frequency is less. That's solid evidence that frequency isn't everything and I hope this example showed you the usefulness of this graph. This was a modest result and you can definitely see more significant results here, but nonetheless, you just got better performance for less money by using the graph to make an educated pick. Hopefully this will save you some money while getting you better RAM performance at the same time. Depending on your hardware, it has been shown that faster RAM can get you more FPS in-game, mainly with integrated graphics or high-end hardware where your memory will likely be the weakest link. This doesn't mean you won't see more performance with mid-tier hardware, but it likely won't be as significant. Video: (this is an update of ThioJoeTech's list, so most of the credit goes to him) If for whatever reason your RAM speeds don't line up on the graph, you can use this formula to calculate the number: "1/(REAL FREQUENCY)1000(CL)=RESPONSE TIME" The real frequency is a module's rated speed divided by two. See second row of graph. Download Excel spreadsheet: -
How much of a real world performance gain would a pc get with tighter memory timings?

Hello, I wanted to upgrade my Potato PC a little bit by adding another 2x2GB sticks of RAM. well i pick same capacity, same frequency but.. after plugin it all in system won't boot. I google it and found that additional memmory I just bought is mismached (it was used one, so can't really return it ;( ) What I got now: 2x2GB OCZ Series Platinum Revision 2 Model OCZ2P800R22GK Speed DDR2 800 (PC2 6400) Cas Latency 4 Timing 4-4-4-15 Voltage 1.9V - 2.1V 2x2GB GoodRam Model GR800D264L6/2G Speed DDR2 800 (PC2 6400) Cas Latency 6 Timing (not sure) 6-8-8-22 Voltage 1.8V Well what I can see now, that event if I will be able to run thoose two It will be slower than my OCZ setup - but really need it to work out. What should I setup and where to begin. Thanks a lot, Kesho -
Hello! ^^ Which result is better? First is stock and second is with increased clocks and lowered timings. Results are just different ._. Any suggestions? I think I can push RAM harder, if needed ;D

Hi guys so I'm gonna be upgrading my aging mid 2012 13" MacBook Pro. I have already purchased an ssd which I will be installing in it, and I will also get more ram(more ram is better, right....). I will be upgrading from 4gb to 8gb (2x4gb) ram. I most definitely WILL NOT buy the ram from the Apple Store, where it costs 200 bucks (totally overpriced) but I want to make sure the ram will be compatible. If have found the ram at the link on Amazon for only 40 bucks, and it states it is Mac compatible and also has reviews from people with the same Mac as me stating it worked. Will this ram work? Or will the timings or latency be different? Just wanna make sure. http://www.amazon.com/Crucial-PC3-12800-204-Pin-CT2K4G3S160BM-CT2C4G3S160BM/dp/B008LTBITY/ref=sr_1_6?ie=UTF8&qid=1449936692&sr=8-6&keywords=Crucial+2x4gb+cl11+sodimm
