New build (10 days old): Ryzen9 5900X + Noctua NH-D15S on a ASUS Rog B550-F Gaming Wifi Mobo, 32 GB (2x16GB) DDR4 3600 Mhz Trident Z RGB, 1 TB PCIex4 SSD + 4 TB WD HD Sata, ASUS TUF RX 6800XT GPU. No overclock, beside A-XMP for memory and PBO on default in Bios, all that in a Phanteks P400a case (3 fans on the front as intake, 1 fan on rear panel as exhaust). As I said in a previous post, I am experiencing high temps with that build, but it seems to be more or less the norm with those components. edit: As per Haraikomono very good comment, PSU is Fractal Design Ion+ 860W 80+ Patinum. What worries me more is that when gaming, I sometimes experience random reboots: no BSOD, just a few "clicks" in my headphones and a simple reboot. Happens once or twice per day max, sometimes after 2-3 hours of gaming, sometimes sooner. For the last two days, Event manager has been reporting a chain of three WHEA-Logger Event-ID 18 when that happens (before those two last days, I could not find anything in Event manager, even when the reboots were happening). When the machine reboots, the RX 6800XT seems to be "off line": even if I unplug and replug the display port and hdmi cables on my GPU to my monitors, no signal is getting to the monitors. I have to restart the PC manually a second time (by pressing the power-on switch 8 seconds) before the GPU sends signal to the monitors again... As I am still in the warranty period for all my components, I am trying to understand what is happening with this machine: faulty GPU ? faulty CPU ?

Allright, thanks for your answer BiotechBen !

New build I just put together: AMD r9 5900X, ASUS TUF 6800 XT, 32 GB DDR4 3600, ASUS ROG B550 GAMING-F Mobo, Noctua NH-D15S CPU cooler (with included thermal paste). Build is not overclocked yet (aside from the AMD XMP-equivalent profile to run the memory at 2x1800 MHz). Concern (?): temps seem pretty high on the CPU, as HWinfo64 reports max CPU Tdies of 86C on CCD1 and 79C on CCD2 under full load (Prime95 stress tests on 24 threads). Also, I have a power reporting deviation that goes from 103% to 124% under full CPU load, seems way too high. Is there something i can do to lower it ? Does all of that seem normal to you ? It seems pretty high to me and leaves me with little room for overclocking, am I correct ?

After further investigation, instability seems to be GPU related: I tried down-clocking (underclocking ?) my GPU frequency and GPU memory frequency by 100 MHz each, and instead of crashing every 2 minutes, CyberPunk 2077 is crashing every 10 mins or so... Worst period to have a GPU failure, so if anyone has some tip to get a 3080 or 6800 XT or MSRP, I would be very glad. As a side note, I am including a screenshot of the event I get everytime I have an in-game crash (definitively seems to point to a GPU problem, am I correct ?).

Hey all, My PC was running fine until a few weeks (or 1 or 2 months) ago. i7 8700K, Asus ROG Strix 1080 Ti GPU, 16 GB (2x8) DDR4 RAM, 1TB SSD + 4TB HD, Asus ROG MB, 750W PSU. Windows 10 21H1 (19043.1110). Problem I have is that some games are super stable (GW2, Lost Ark RU) while other are crashing to desktop every 5-10 minutes of playing (Outriders, CyberPunk 2077, Grounded, Sword of Legends Online,...). When I noticed that those problems were recurring way too often for normal random crashes, I ran some stress tools: Unigine Superposition for the GPU and Prime95 stress tests for the CPU. Both run without any crash (Unigine) or error/warning (Prime95). All temps and other parameters seem normal in HWMonitor. I reverted to some older Nvidia drivers, no change. I installed the current hotfix ones (471.22 I think), no change. I re-installed Windows 10 from scratch, no change... I am at a loss. The only thing I could think of is PSU maybe, but that does not explain why Unigine Superposition runs super fine both in benchmark and game modes... Plus I do not know how to validate that theory to be honest aside from buying a new PSU... Does anyone have an idea, I am really at a loss there ? Edit: forgot to add that the PC is 3 1/2 years old (november 2017).

Hey guys, This is a (happy) follow-up to my previous thread. If it may help someone, then all the best. First of all, let me link my build: https://ca.pcpartpicker.com/list/kgjPRG. After the previous thread, feeling a bit lost but not wanting to give up, I searched a bit more on the web and found this video. I was lucky: even if the mobo he uses is the high end version of mine, the BIOS-UEFI looks the same. I applied his recommendations and, as I was stable in every stress test I conducted, started to lower my Vcpu to lower my temperatures. Finale results : 5GHz stable on 6 cores (4.7 for AVX/AVX2 applications) at 1.32V (Vcpu) with max temps of 75 Celsius during normal usage sessions (CPU-demanding game maxed out - Assassin's Creed Origins + twitch streaming - OBS 64 + Discord), and 80 Celsius max during non AVX stress tests (Cinebench, Prime95 26.6), 85 Celsius during AVX stress tests (RealBench stress tests). Quite happy about the results, I will not push further as my goal was to reach 5GHz stable without deliding.

Indeed if you have no LED on the Motherboard when you boot, it points out to a fried Power Supply. Make sure the switch on it is on the "1" position, but if it is indeed, then it probably fried.

Ok so an update this morning: I managed to run a stable 5.0 GHZ OC on all cores, but I am not satisfied with the results, at all. I seem to have gotten a really bad 8700K. Basically, to pass the Prime95 blend tests, I have to put an offset of 0.03V on Vcore and a Load Line Calibration of 4 (Auto or 1 to 7 on ASUS Boards). According to HWmonitor, the Vmax delivered to the CPU under load is 1.411V, which leads to a power of 185W and a temp max of 97 celsius. I even saw some cores of the CPU throttling down to 3700 MHz during the most intensive Prime95 (8K FFT). I use the machine mainly for gaming and streaming, plus regular office work. Nonetheless, as a nerd/geek I like to push my machines to the limit... In short, I do not know what to do with this, as I read some posts of people with the same mobo/cpu who easily reach 5 GHz on all cores... There is even an option in ASUS UEFI to load presets for 5GHz stable (which obviously lead to unstability for me).

Interesting facts: by disabling XMP and manually configuring the same settings, and by using a Vcore offset of 0.02V instead of a manual Vcore of 1.35V, I can reach 4.7 GHZ stable on all 6 cores, with temp max for package being 92 celsius during the 8K FFT test (the most CPU intensive one). I will try to push a bit further. If I can not, I will settle to your recommendation: 2 or 3 cores at 5, the rest at 4.5 or so.

Hey guys, looking for help there as I am a bit of a loss. Built my new rig around 8700k, ASUS ROG Z370-F, Corsair H100i v2, G.Skill Ripjaws V DDR4 3200 (2x8 GB). My goal is to achieve 5GHZ in turbo mode on all 6 cores, which seems to be very doable with that build. Yesterday, I thought I reached my goal, as I got no error in Prime95 after 1 hour of tests (blend, mix of everything): I set the 6 cores at 50 in BIOS, and Vcore manual at 1.35. Temperatures never went above 86 celsius (package, in HWmonitor). But then I noticed something strange: even if the XMP profile was enabled in BIOS, as I set "Allow odd DRAM timers" to disabled in BIOS, memory was not running at 1600 MHz but at its native speed, 1033 MHz... So today I enabled this settings in the BIOS, and I can not reach anything stable: I always get error on the second test of the Prime95 blend tests (the 8k FFT one, producing lots of burst of rapid calculus on your CPU). Temperatures are much higher (around 90-92 celsius), and I always get the rounding errors. So I am kind of back to square one so far: it seems I can either run at 5GHz 6 cores but with RAM in JEDEC mode, or at the default of 4.3 GHz on all corers with RAM in XMP mode... I am hesitant to push the voltage higher, as I already reach 90-92 celsius... Any idea? Does anyone have the same experience with the same mobo ? BTW I have the latest BIOS, 0430. Thanks,

Thanks for your answer IO Studios. If I wanted to go liquid, which AIO solution would you recommend? Not sure I am confortable enough building my own water cooling solution from scratch.

Hey all, I am planning my new build right now, and I would like your feedback about it. Preliminary part list is available here. Keep in mind prices are in $CAD. I would like to get some feedback around this build. In particular, around the CPU cooling solution, the memory, the case... Build is used mostly for gaming, but also as ma main productivity/media tool (some streaming, some video editing, lots of gaming:) ). Currently, my main machine is built around a 3770K OC'ed to 4.2 GHz, a 980 non Ti, 750 GB of SSDs (SATA, not PCIe), 2TB HD, and an Antec basic AIO water cooling kit I am not entirely satisfied with (noisy, not super efficient). Will I see a huge improvement with this new machine ? My monitor is a Full HD one, but GSync'ed capable up to 144Hz. So the 1080 Ti may be a bit overkill but at the same time should allow me to max out settings while achieving 90-100 fps in most demanding games. What do you think ?
