Greetings, fellow earthlings!!! I'm facing a pretty peculiar problem(probably not all that rare). quick overview: PC works fine for a few months, then stops booting. Taking 2 RAM sticks out solves the problem. PC boots. for more details, read the paragraph below. My PC was working fine for a few weeks, then one day, as i was browsing on firefox, my system freezes, i reboot and resume reading the same page. system freezes again and now it won't boot(no display but all the graphics card lights and fans and their lights turn on). The numlock lights won't turn on either. the PC acts like it's booting, takes about 8 to 20 seconds and restarts (only once) and then stays like that(fans on, lights on, no booting). it does not restart multiple times either. I have to manually shut it down by holding the power key for 8 seconds and then restart it for the same drama(it restarts only once and then stays stuck with all lights on). If i take out two of the four RAM sticks, it works. (mobo supports total of 8. i read the user manual and installed the RAM accordingly in the grey slots first). Specifications: Intel 6800K at stock speeds and voltages Nvidia GTX 1070 (ZOTAC AMP Extreme) Gigabyte G1 Gaming 5P motherboard CORSAIR VENGEANCE LPX 32GB (8x4) DDR4 2400MHZ RAM with timing 16-16-16-39 1.20V (running stock, no OC) [The RAMs are 2 packs of 2 sticks each for a total of 4 sticks. I checked the timings on the RAM before buying them. Both the packs of RAMs are 16-16-16-39 speed. The serial numbers indicate that the sticks were just 47 sticks apart.] [the RAMs I have are not on the qualified list of vendors on the gigabyte's site. However, the list has CORSAIR RAMs as well as 16-16-16-39 @ 2400MHz RAMs listed (although not both together ie: not CORSAIR 16-16-16-39 none of the approved CORSAIR RAMs are 16-16-16-39)] 500GB 850EVO SSD by Samsung. Kindly advice how to proceed. The aspect that puzzles me is that they worked fine together for almost 2 months(all 4 rams in the grey slots) doing some pretty intensive stuff. Video renderings, FEA simulations, ultra large files photoshop and the likes. can i change anything in the BIOS to make my MOBO stop fussing and accept the RAMs??

I've just received and set up my shiny new Steam Link because it was on sale. My PC is in my room, and my router is downstairs. My PC is wired to my router via Powerline, and steam link is Ethernet directly to the router. Except for the Powerline adaptor (which is 500Mb/s), everything in the chain is gigabit. I'm experiencing a lot of dropouts and latency issues with the steam link when using to play Dirt 3 (all I've tested so far). I'm using the router supplied by my ISP (BT home hub 5). My question is really, what can I do to improve performance? My initial thought was get a new router, but I wanted to check this is probably the source of the issue, before I go shelling a load of money on a new router. Anyone experienced anything similar on the home hub 5 and found a new router solved their problem? Thanks!

I've just built a new system, and am setting a performance baseline before I start overclocking. I'm seeing some very strange results with the memory tests. Ryzen 7 1700 (running stock at 3.0 GHz) ASRock AB350 Pro4 (UEFI version P2.50) Corsair Vengeance LPX DDR4 (2 x 8GB) 2666Mhz RAM (CMK16GX4M2A2666C16W) the RAM is installed in slots 2 and 4 (A2 and B2) Looking at CPU-Z, the RAM seems to be running to spec... http://imgur.com/a/ryIvF When I run the Memory Mark benchmark (Performance Test 9.0), I get a memory latency score of 83. The average score for this model of RAM is 28. My score is in the 5th percentile. http://imgur.com/nJG3uoz Complete results (comparing to benchmarks for the same model RAM) database operations: 65th percentile memory read uncached: 87th percentile memory threaded: 98th percentile memory read cached: 78th percentile memory write: 71st percentile memory latency: 5th percentile The RAM is on the qualified vendor list for this motherboard. I tried asking Corsair, but I got the boilerplate reply " Unfortunately, we cannot assist with synthetic benchmarks results as we don't test that. " Any suggestions? What other kinds of tools do people use for testing or benchmarking memory?

Hello everyone, i have been having trouble in the past week and a half now being able to play video games due to what I believe is rediculously high latency problems. I can handle anything else on my Xbox (Netflix, Amazon, Web Browsing, etc) but the second I hop on a game such as Overwatch it lags so badly that it is unplayable. My detailed network work statistics range between: Download Speed: 40-55 MB/S (this is normal) Upload Speed: 0.75-3.0 Packet loss: 0% (consistently) Latency: 200,40,1327,1700,252 I also ran test on Speed Test: My Ping is 10 and my download/upload speed is consistent to above speeds. Any information would be extremely helpful and much appreciated. Thanks! Edit: I have tried to reset my extendeder, router, and port box. I have also also attempted to reset my Mac Address. I have also tried hard resetting the Xbox. My NAT type is also: Open

Hi, I've been trying to figure out whats wrong with my wifi for about 2 weeks now. My internet subscription is 25 mbps. Last week, I've been playing games like Dota 2 and CSGO and I'll start with 20-40 ping and it will go up like crazy until 400+ (500+ on CSGO). I check my speed test and I only getting about 15-17mbps sometimes it goes down till 13mbps. Before when I check my speedtest I normally get 26mbps. 1 mbps higher than what I'm supposed to get via Wifi but now its lower now. Ping is way higher than before too. sometimes I do speedtest and I'll get like 7-9 ping now I'm getting like 16-20 ping. upload speed doesn't have much changes. It's unplayable so I decided to call my ISP (Lightspeed) for technical support. We power off both modem and router for 2 mins, open it up and check, still the same. We tried wired connection with the router, I still get the same result. When we tried to remove the router from the modem and did a wired connection (Modem doesn't have wifi) I got 8 ping, 26.75 mbps and 6.75 mbps upload speed with a stable graph once it reaches its peak. We tried getting the router back on with wired connection and did a speedtest still the same as before but its a bit different. I got 14 ping, 19.54 mbps download and 6.47 upload. My ISP told me that he can't fix the issue with my router as it seems their modem is giving the right speed but not my router. I decided to get a new one. Old router is asus N56U, new router is TP Link AC1750. So I run a speed test and I get 14-16 ping, 19-21mbps and still a stable upload speed. I played during the night I still get my ping goes up like crazy but it quickly goes down and the lag during playing is barely noticeable. The next day I tried playing during the afternoon and my ping goes back to what it is. After losing again because I just can't play, I check my speed test and it was at 18 ping 14mbps and same upload speed. This is giving me headache. I don't have this problem before. I don't know how to fix the issue. I'm also quite close to the router and the microwave is far away from me and the router. Pls help. I don't know what I'm supposed to do. with the new router I also did try doing a wired connection and it is still the same.

hello all! I wish to record my games, but I can only do it at 30fps (have to set the limit in game). if my ping is high (~100ms) will the latency due to 30 fps affect the overall latency of the game? I hope my question is clear. (it is in my head)

Hi, I have bought a new Dell Inspiron 7559 with SK Hynix 8 GB DDR3L ram and I have another G. Skills ripjaws 4 GB DDR3L RAM with me. The problem is the both RAM work at different CAS Latency but on similar clock speed & voltage. Will it work as intended and cause no issue and is it a good option to mix both of them or should I just buy a new RAM?

Although I know Zen is still over a couple months away, I've been looking at dual channel 16GB (2x8GB) kits & am wondering about something. It's true I could just get Corsair Vengence DDR4 2133 with 13 CAS & be happy with that, but what would happen if I got G.SKILL TridentZ or Ripjaws V DDR4 3200 at 14 CAS & underclocked them? Would that reduce their latency below 13 & still maintain a higher speed than the budget RAM?

Hello everybody, without much talking straight to the question. Does limiting fps in pc-games create more input lag, or some latency? The main idea is that the game engine pushes for example 200+ fps to the monitor (with a good gpu), the monitor supports for instance 60hz or in best case scenario 144/165hz (fps) so you limit your 200+ fps to 60, 144 or 165 according to your monitor to have smoother gaming experience. Does it mean that by limiting my fps i create some bottleneck towards my game engine and therefore will get some latency or greater input lag in gaming? I am a bit confused about how this thing exactly works. Could someone explain it, or give some links, advices etc? Thanks

Hello there So here's the the thing,i've already got a ram stick "hyperX savage 2133mhz cl13" and i want to add another 4gb of ram of the same brand "hyperx savage 2666mhz cas13" and my motherboard support 2133mhz My question is: will this work ? if not,what will ?(apart from the EXACT same model of stick that i already have, since,after research,is unfindable )

I am getting an RX 480, but my monitor is only vga (please do not roast on my screen, my card died and now i must replace that first before the screen) I got the standard RX 480 which does not have a vga or any kind of analog connection. I would need to get an active adapter. What i wanted to know, do active adapters add a lot of latency, I'm a gamer so i kinda need to know. Tnx in advance ^-^

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 >_<

So I have NewWave, basically the only high speed internet solution in my area. I have the basic package, 100 mbps down, 10 mbps up. Here’s the issue, normally when playin online games I have no issues. My latency is typically between 20 ms and 80 ms depending on the game. Lately, for about the last week, my latency has been spiking anywhere between 34 ms to 600 ms, making rubber banding a very big issue, and a tendency to be kicked from competitive ranked games. I’m also going to start working from home soon, using a remote connection to a VM. Solutions I’ve tried already include soft resetting the router, unplugging the router for 5 minutes and plugging it back in, and calling tech support (which basically told me to do the same exact thing). Other points of interest, my device is not the only device in the house experience the issue. The connection is wired Ethernet. I have checked all physical connections, including the coaxial cable to the router. I have done ping tests from multiple devices, including the router itself, and all are spiking around the same ping. Also, I am not getting any dropped packets while testing. Any ideas of what I should do? Should I call tech support again? Also, as for the 10 mbps down, I normally only get 2-3 mbps up and 5 mbps up on a good day. I know they advertise it as “up to 10 mbps.” But it kinda sucks when you are trying to even upload videos or use Skype/Discord. Should I bring this up the next time I call? And before I get the obvious “get better internet” comments, I have already stated that this is the only solution for me at the moment for anything more than 20 mbps down via DSL. And I’m not willing to move to a different area just to have better internet. Also, I understand that some people might think that just upgrading the internet package might be what I need, but it’s not the speed that’s the issue, it’s the latency.

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

Hi. I've been breaking my head to understand Infinite fabric (IF) & how high of a clock speed RAM I should/could choose with the new AMD Ryzen series. I saw a picture (attached) that shows the sweet spot being 3733mhz CL17 yielding 67ns latency. While 3600mhz CL16 yielding 69ns is the best value-price/performance for 1:1 ratio/mode. But higher clock speeds getting in 2:1 ratio/mode with 4400mhz CL18 at 75ns latency. I'm currently searching all over the net to understand this Ratio mode & Latency. And I'm only finding bits of info, not a full explanation. From these 2 videos, I've learned that Infinite fabric is the system bus speed. Both between cores in the CPU module & as the entire motherboard of components. Memory, pcie, and usb-C 3.2 etc. Now I'm hoping someone "scientific" can please explain to me, the mode/ratio 1:1 & 2:1 on the Infinite Fabric system bus . (q1) What does it mean to the system? Does 1:1 mean > 1 to 1 cpu/mem cycle? and 2:1 meaning 2 memory cycles per 1 CPU cycle? or something else? On the official AMD picture, they state that at the shown speeds, they are plug & play and JUST works. (We all know memory ram is always sensitive to compatibility, but working ram listings aren't even listed on ANY x570 motherboards manufacturers website and neither the ram manufacturers.) The speeds shown to work via XMP, like if I install 2dimms - 3600mhz CL16 on 16-16-16-36 timings, rates at 8.89ns latency. But it's latency in relation to IF system bus is shown to work in 1:1 mode yielding 69ns Raw memory Latency. And if I installed 2dimms - 4400mhz CL18 on 18-19-19-39 timings, rating at 8.18ns latency, it's shown to work in 2:1 mode yielding 75ns Raw memory Latency (q2) Please explain to me in a bit of detail, on how the mode functions? Does it switch modes by detecting the memory speed in mhz? or CL? or both? (q3) How does the mode affect the system? is 2:1 mode something like a more buffered response to it's controllers/drivers whereas 1:1 is not? (q4) What processes are happening behind the modes, that 8.18ns of 4400 CL18 results in 75ns system latency. (q5) Which 2 of the modes are best for which scenario? as they stated the sweet spot for performance is 3733 CL17 in 1:1 mode. So what is 4400 CL18 in 2:1 mode then? Sweet spot for stability when overclocking? I hope you'll google with me to try figuring this out thank you in advance for answering those 5 questions I have. (PS. this is about understanding the AMD configuration once and for all, & the way it's best supposed to be used. Not a topic about if it's overkill or not.)

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

Hello all, In my journey to build my first PC, I've found the subject or RAM to be trickier than I had anticipated. Initially I thought RAM was a simpler, less expensive component of building a PC...oh how wrong I was. So now I'm forced to yet again ask the good people of this forum for a bit of guidance so that I can hopefully get my questions answered. I plan to use a Ryzen 2700X CPU, ASUS ROG X470 motherboard, and G.Skill Trident Z RGB RAM (because, you know, pretty lights and all that). So here are my questions. What is more important, speed or CAS latency? i.e. Which would be better, 3200MHz CL16, or 2800MHz CL14? There seem to be some memory cards pre-configured or optimized for AMD CPU's, is this some specialized intrinsic feature within the memory, or merely just preset optimized timings that I could set within my BIOS once I set up my PC? Is there anything else I should keep in mind while RAM shopping? Thanks in advance.

Hi there, I am looking at the OLOy WarHawk RGB 32GB Ram and I see that they offer two different CAS latency options. One is 18 and the other 19. There is a $10 difference between the two and I am wondering if that is worth the price difference. I am thinking probably not. Thanks!

Hi all, While I like to think I am good with technology and computing, I do admit my one downfall is networking. I know enough, and probably more than most of the general population (Thank you, LMG). Having messed around with settings, I've decided to see what more knowledgeable people think of my situation. So, I currently live in a Student Studio flat, with no thoughts of leaving until I graduate. Each flat has it's own Ethernet connection of which students must buy their own router and connect it to the Ethernet port, should they want to use the internet that is included with the rent. I've now lived here for over a year and had plenty of time to experiment with settings to try and improve the internet. The internet speed is absolutely fine and excluding the daily 5 minutes of downtime that appears to occur, connecting to the internet is no problem. The issue I have could be considered a 'first world problem'. The way in which the network is set-up does have it's problems. For example, some multiplayer games will have problems during game-play with packet loss and latency variation, spiking from anywhere around 20ms up to 140ms (Sometimes WAY higher), back down to 20ms is a matter of a couple seconds. Rocket League is the main offender for this. All other internet browsing and even streaming video seems to be fine (Though, Twitch can have buffering issues occasionally). Further, my Xbox provides detailed connection information and informs me that the connect is a Double NAT. From my understanding, this occurs when a router is connected to another router. Obviously, there isn't very much I can do about this. One solution that fixed most of these issues was using my router as an access point. This reduced the number of connection errors I had during multiplayer games, Twitch no longer buffered as much as before and my xbox no longer report a double-NAT. I thought I had out-smarted the student block! However, I have concerns that perhaps this solution is a dangerous one from a security standpoint. My devices still require a password to connect, but once connected to my router (now access point), were now connected directly to the central router of the student block. I left this for a couple weeks, but today noticed that my Spotify Connect showed a PS4, not something that I own, never mind signed into. This, at first, made me wonder if someone had somehow connected to my router. I checked my control panel, no PS4 or unknown devices connected. Still concerned, I downloaded a network watcher, and as some of you were probably expecting, it came back with a list of ALL of the routers connected in the building, plus my devices and the PS4, of which the owner probably had the same problems as me with Double-NATs and ping. I have now gone back to using the router as a router, now my network watcher just shows MY devices and router. Sadly, this does mean that my Xbox will now remind me of my Double-NAT connection, Rocket League will time me out from matchmaking for disconnecting during a game and Twitch will buffer as it did. Does anyone have any solutions to this? I assume I should keep away from using my router as an access point? Shall I just suck it up, get over it and stop making such a fuss over having an internet connection that is probably more stable than half of the worlds? Many thanks in advance!

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

3 weeks ago I noticed that my computer started stuttering for a second or less while playing music, videos and videogames. Video and audio will stutter for a brief period of time randomly almost always 5 minutes after I begin playing media or randomly every 20, 30, 60 minutes or so. My specs are: Ryzen 2400G RAM 2 x 8GB Hyper X Fury 2400Mhz DDR4 Asrock X370 Taichi Samsung SSD EVO 850 500Gb (windows is installed in this drive) Toshiba HDD DT01ACA100 1TB Gigabyte GTX 1080 G1 Gaming PSU EVGA 550 W L1 LG 27MK400H-B Monitor Windows 10 Pro version 1903 OS build 18362.175 In the previous weeks I have tried to identify what is causing the stuttering to no avail. While using Latency Monitor the "Highest measured interrupt to process latency" and "Highest reported DPC routine execution time" bars get red when the stuttering occurs, and gives me the same message telling me that "one problem may be related to power management, disable cpu throttling settings in control panel and BIOS setup". I have tried every fix internet recommends but nothing works. This is the list that things I have tried and failed: *Updating motherboard BIOS *Replacing motherboard (I had an Asus Prime B350M-a and just replaced it with a X370 taichi days ago) *Disabling C-States and Turboboost in BIOS *Disabling Power Throttling Using Group Policy *Clean Windows install *Remove GPU and HDD (stuttering persists on a clean Windows install without GPU and HDD) *Overclocking CPU *Running Windows Memory Diagnostic *Disabling W-LAN, Ethernet and Sound devices with Device manager *Disabling HPET (High Precision Event Timer) on Device Manager (board BIOS has no HPET option) *Changing Default Audio Format *Updating drivers *Installing a previous Windows 10 version *Disconnecting peripherals (stuttering persists with just mouse and keyboard connected) *Switching to High Performance or Ultimate Performance Power Plan *Checking HDD and SDD health *Checking if CPU and/or GPU overheats ===IMPORTANT=== Recently I discovered that if I switch power plans while playing music or video (offline or online) the stutter occurs immediately and also when launching HWINFO64 (with either option "Sensors-only" or "Summary-only"). Some other information that may help diagnose what the problem is: *I run my CPU and RAM overclocked to 3.8 Ghz and 2666 Mhz respectively (the stuttering persists with CPU and RAM default speeds). *I switched my GPU from a RX 480 8GB to a Gigabyte GTX 1080 G1 Gaming 10 days before I noticed the stuttering. *CPU and GPU temperatures are optimal all the time. Please help me diagnose what is happening with my PC. Thanks

I've recently updated my Ryzen 1700 system, and an issue that had been occuring in the past is now popping up again after I: Updated Windows to 1903 Updated radeon drivers to 19.7.1 Updated chipset to 1.07.07.0725 Updated BIOS to 7A37vAI (MSI Mortar Arctic b350) The issues are high latency and latency spikes which translate to perceptible stutter and lag. I've replaced many components over the last year and sent in my ryzen 1600 and got a replacement upgrade to a 1700 because of a lack of stock at the time. Since then I haven't really had any issues other than stutters if i leave the system on overnight while I watch YouTube videos to go to sleep. Just a quick system restart used to fix them them however. Anyone having similar issues? Why would the problems leave after a CPU upgrade and then come back after some core driver/bios updates? In the past when these issues were present I tried everything from removing overclocks, updating everything I could, reinstalling windows, to even RMAing the motherboard, powersupply, and CPU. I've also disabled/enabled HPET and lowered SOC voltage. Do you think you can help me point to a specific component that's acting up perhaps? Is there something I simply need to update/install that I haven't yet? ANYTHING is appreciated. I have a hunch that my RAM is to blame but I don't want to start spending money and throwing darts at the wall if I can simply fix this issue another way.

Ok, recently I've been having lots of problems with my internet. For starters i dont know much about all this, im just trying to gather all the help and information i can to fix this. Im having 20-50% packet loss and is almost constant. Im a gamer so i play a lot, i try to compete in tournaments but my internet has stopped me from doing so. Ive changed DNS, reset both my router and modem more than once, updated firmware on both, changed and tried different ethernet cables but the problem is still there. I also checked my bufferbloat and it goes through the roof. Im talking about 1000ms+ bufferbloat, I pinged my ip between pc and router and it says i have 0 packet loss so im lost, i dont know what else to do. Im going to call ISP and get a tech in to see if theres any bad cables or anything because this problem is getting into me and cant play or even watch anything without lagging or stopping. Modem: CM700 DOCSIS 3.0 Router: Netgear R6700 Nighthawk AC1750 I have 150mbps down and 10 upload speeds. If you guys can suggest anything else ill be more than glad to hear.

Hello, from the last windows 10 update i had some problems with my pc and one of them is the wifi connectivity. The problem is with both my wifi cards having high ping (or timing out) from my router to my pc. I have a Sitecom WiFi USB Adapter N150 and a Realtek 8821AE Wireless LAN 802.11ac PCI-E NIC (that i have recently bought because i tough that the usb was dying). Below there are some images from my ping tests for my pc and my android phone (to disprove the malfuncioning of the router, the test was done at the same time for both the pc screenshots and had the same results, so i posted only one of them). The pc test was made with the wifi usb adapter after the installation of the latest drivers but the problem was the same even without i manually intalled them... Same issue is with the PCI card (wich is a plug and play and the online drivers are older than the installed ones) Any one has an idea ofwhat could be the problem? Ask me any additional info and i'll reply as soon as possible! Thanks!

Okay... So, call me the prince of indecision, I guess I am deserving this title. Very well, enough rambling... So, as I am planning on a new build I often came to this forum to seek for help, as I did a couple of times to get help choosing a CPU, after all the help I got I decided to purchase a Intel CPU, more specifically the I7 9700K... And now I am wondering, how to choose a RAM module for a Intel CPU? I know now that RYZEN benefits from quad channel and high frequencies... What about this chip, what should I look for when picking up a RAM for this CPU? PS. I accept recommendations.
