Totally fair. Thanks again!

Awesome, thanks so much again. I will definitely take a closer look into the video and see what the optimal settings are for my build. Just wanted to ask again though as I have this obsessive need to try and understand/make sense of things lol. Do you have any theories at all about why PBO advanced seems to give me the reboots, even if everything is on auto and no CO or clock boost? I would’ve thought that’d essentially be the same as PBO Enabled, no?

Thanks for the reply @Beerzerker! So I'm back after a bunch of testing, and it's kinda strange. I'm pretty sure I tested with BIOS defaults as well as with and without PBO enabled etc before, but I guess there must have been some mystery setting that wasn't cleared or something because I seem to have pinpointed the issue. Or maybe given the fact that I tried so many settings, I might have missed something at some point. Basically, it seems that when I set PBO to Advanced in BIOS, regardless of whether I enable curve optimizer or a boost overclock or not, I get the reboots. For instance, setting PBO to Advanced, and having everything on auto, alongside curve optimizer disabled and boost overclock disabled (know this is pointless but did for testing purposes) gives me the reboot. Curve optimizer negative values of even 1 = reboot. No curve optimizer but boost of 50mhz for instance, also reboot. PBO enabled as opposed to Advanced = no reboot! That being said, I tried this (i.e. CPU voltage override at 1.27v) without setting the CPU at a specific speed and PBO disabled, and the CPU was performing below stock clocks (around 3.4-3.5 GHz). I guess that's expected unless I force the CPU to the stock speed, right? I will also test the voltage override with the chip at stock speed, however, am I right in thinking that in that scenario, the CPU will definitely not go over 3.7GHz which I believe is the stock speed? Or will it still try and boost further up if there's headroom? With the rest of my testing, it seems like I am getting the best results with PBO Enabled, RAM on XMP 1 and a CPU voltage offset of -0.1v from a CB score and clock speed perspective (boosts up to 4.4-4.5GHz). With all of this said, I still would love to know if you have any inkling as to why PBO advanced settings seem to give me the reboots regardless? I wonder if it's the sudden drop from 1.4+ volts on the CPU down to 1.1v or thereabouts (on heavy load) with the curve optimizer etc? I'm not very proficient with undervolting/overclocking so apologies if that makes no sense lol. Even if that was the case, shouldn't PBO on Advanced with no curve optimizer and no core boost still be stable? Am I just tripping or does something seem a bit strange there? Also wondering if there may be any scenario where I could run a stable curve optimizer. Maybe custom PBO limits for PPT/EDC etc? I did test a bunch of those though and couldn't seem to get it stable. I do want to peddle back to this too - definitely not questioning this, but just trying to understand the reasoning you have for saying so. I seem to recall reading on a lot of forums where 1.4v is deemed pretty normal for Ryzen 5900x on idle/low loads and totally fine. Is this something you think is the case with certain motherboards and Ryzen 5000s etc? And shouldn't the BIOS defaults be adjusted as such if that is way too high? Thanks again for all your help

Thanks for the suggestions! Can I just ask which setting you're referring to in the BIOS? Is it just the CPU core voltage? I'm still relatively new to a lot of these settings, but my understanding was that curve optimiser does something similar by basically reducing the voltage under load. That being said, the default voltage for the CPU when idling remains steady over 1.4v from what I can see, so I also wonder if this issue is somehow caused by the fluctuations in voltage. But that's a completely uneducated guess so I am sure I'll be corrected lol. I should say that this is the second 5900x that I got in my system - the first one I had to return due to similar issues with a little more instability, so I do lean towards what you've mentioned in that this may be something to do with the motherboard and the CPU's compatibility. They are supposed to be compatible with the latest BIOS, but perhaps it's not a great match? Definitely a shot in the dark, but I'll check this too and report back. Thanks again

Hi everyone, I had previously posted about a similar issue but I didn't want to revive a dead post which at the time I thought I had resolved. Apologies in advance, this is going to be a long and messy post, please do let me know if anything needs clarifying! The problem I have been using my build (specs below) for quite some time now with no issues, however, recently I started doing some editing in Premiere Pro and my PC started to reboot whenever I was rendering or playing back rendered video. This reminded me of my previous issue where I could not run Cinebench multi-core tests - as soon as I hit start, the PC would reboot. No BSOD or error messages. I previously resolved the Cinebench issue by updating my chipset drivers. When I had the issue with Premiere Pro the other day, I decided to try Cinebench again, and lo and behold, the same issue is back. I also started to notice this issue in Spider-Man Remastered. I cannot not play the game because of it. As soon as I get past the first cut-scene of the game, bam, reboot with no BSOD. I have checked Event Viewer on each occasion, and all I can find is a critical Kernel-Power event ID 41 task category (63). All other games and high and low load activities except the above, I never have this issue. I was running a curve optimizer with negative 5 on all cores, +100MHz CPU boost override and PBO limits on Auto when I first encountered the issue. So I figured the problem may be these settings, so resetting BIOS to defaults was one of my first go-to's. I also kept a check on temps and everything seems within "normal" ranges for Zen 3 as far as I can tell. Usually ranging from 50C to 80C under max load, depending on whether I have custom BIOS settings or not of course. Including my specs, what I've tried so far and some findings/things to consider below: Specs Mobo: MSI B450M Mortar CPU: Ryzen 9 5900x CPU Cooler: NZXT Kraken X62 AIO Water Cooling Unit - 280mm rad (behind the rad in pull config) GPU: MSI RTX 3090 Ventus 3X 24GB GDDR6X RAM: Kingston Fury Renegade DDR4 3600MHz CL16 32GB Kit (2x16GB) - XMP Profile 1 PSU: Corsair RM 850 W 80+ Gold Fully Modular ATX PSU initially (note - I have now upgraded to Corsair RM1000x as I was convinced my issue was with my PSU, but that did not resolve the issue) Storage: WD S3750 1TB NVMe SSD with Heatsink Case: NZXT H400i mATX What I've Tried So Far I will outline further below the scenarios in which I was able to run Cinebench either fully or for a few minutes, but first, a list of all of the different things I have tried. Checking Event Viewer for clues (critical Kernel-Power event ID 41, TC 63) Removing undervolt/OCs, resetting BIOS settings to default Downloading the Cinebench app from the Microsoft Store as opposed to from the Maxon site Closing all other apps when running Cinebench, Premiere Pro etc. Disabling antivirus etc. Trying to watch for signals using HWInfo - what happens just before the PC reboots? [I can't see anything unusual - too fast!] Adjusting fan curves in NZXT CAM Updating BIOS to the latest version Uninstalling old chipset drivers and installing new chipset drivers Testing RAM for errors with memtest86 - no errors found on 2 passes Disabling memory fast boot Disabling fast startup in Windows Changing PSU from RM850 to RM1000x (most of my tests were run on the new RM1000x) Testing with PBO on Auto, PBO disabled etc. Testing with custom PBO limits such as 142 PPT, 90 TDC, 140 EDC / 185 PPT, 125 TDC, 170 EDC Disabling Global C-State Control Testing settings like Power Supply Idle Control on auto, low and typical current Trying to lower SoC voltage from 1100 (default) to 1000 Lowering both VDDG voltages to 0.950v and VDDP to 0.9v Testing load-line calibration on a variety of settings including auto, mode 1, mode 2, mode 3 etc. Testing with RAM on XMP profile 1, 2 and default (2400MHz) Testing different Ryzen Master recommendations (tried auto overclock, PBO enabled + curve optimizer for -29 on all cores etc). I've tried so many different settings that I have probably missed a fair bit above, and I didn't take note of all outcomes either. However, in a few situations (see below), I was able to run Cinebench fully and render/watch video playback in Premiere Pro, and even play a little Spider-Man Remastered, but I re-encountered the crashes later. These did seem kind of random though. It feels like either something in my BIOS settings or perhaps drivers is causing some issue? It's driving me insane at this point so I'd really appreciate any thoughts you might have. What seemed to help (but not resolve) the issue Default BIOS settings, PBO disabled, no XMP profile on RAM (2400MHz default) - Cinebench completed 1 full 10 minute multi core test, I started another one for good measure and 2 minutes in I again got a crash but this was better than not being able to run at all PBO enabled in BIOS with custom PBO limits: PPT 160, TDC 115, EDC 140 and curve optimizer on -28 for all cores and a +50 MHz boost clock override , RAM on XMP profile 1 -> ran Cinebench fully once, but Premiere Pro still crashed I'm sorry for this mess of a post and I realise all this info is probably muddying the waters more than it's helping but I'd really appreciate your help folks! TIA

Update: I've tried uninstalling G Hub, NZXT CAM and others and running. Issue ongoing. I also wanted to monitor task manager for a bit to try and spot what application might be causing the CPU spikes which seem to lead to the black screens. I see Windows Audio Endpoint Builder coming up and hogging a fair bit of CPU when a black screen occurs. Tried restarting the service and changing the details on the Log On tab as well as uninstalling & reinstalling sound drivers but still no luck. Anyone have any ideas as to how Audio Endpoint Builder might be linked to the issue?

Bump

Hi guys, I've been having 1 or 2 second black screens while gaming for a few months now and this has been driving me insane. Essentially the screen randomly flashes black while I'm gaming (or if I have a game open in the background) and in most cases, I often hear a USB/device disconnect sound (not always) when this happens. This is momentary and the picture comes back within 1 or 2 seconds max and I can continue where I left off. I've been searching for answers and have checked a number of things which I'll share below along with my specs. The issue seems to happen mostly with games like Sekiro, Call of Duty (MW) and GTA V. It doesn't happen as often with less intensive games like World of Warcraft, but I have had a few flickers with WoW too. I play in 1440p, refresh rate of monitor is 60Hz. Temperatures while gaming with max/high settings on CoD are around 50-60C CPU, 70-76C GPU with ~75-95% GPU use in game. One thing I recently noticed is that when the screen flashes black momentarily, CPU use spikes to 100% each and every time, feels like that should be a useful hint as to the root cause of the issue but I can't pin it down. Apart from that, CPU usage typically varies from 50-80% with CoD. Ram usage around 65-75% most of the time. Important to note the issue only seems to occur while gaming or when I have a game in the background. Cinebench doesn't seem to cause the flickering, but it does occur with Heaven. Specs: Mobo: MSI B450M Mortar CPU: Ryzen 5 3600 (not OC'd) GPU: MSI RTX 2070 Super Ventus OC 8GB GDDR6 RAM: HyperX Predator DDR4 3200MHz CL16 16GB Kit (2x8GB) - XMP Profile 1 PSU: Corsair RM 850 W 80+ Gold Fully Modular ATX PSU Storage: WD SN750 1TB NVMe SSD with Heatsink OS: Windows 10 64-bit What I've Tried So Far - Checking all cables, ensuring GPU is seated properly - Running games on all settings from lowest to the highest, as well as trying 1080p again from lowest to highest settings - Running games in windowed & other modes. - Playing around with various settings including VSync, MSAA, FXAA, DirectX Raytracing etc - Running games without MSI Afterburner, RivaTuner, Avast, Chrome etc in the background - Checking Event Viewer for errors etc (none found) - Updating, clearing & reinstalling graphics drivers multiple times, uninstalling and reinstalling related software such as NVIDIA Control Panel & GeForce Experience - Running games with and without NVIDIA GeForce Experience optimal settings and testing with NVIDIA Control Panel Quality, Balanced and Performance settings - Trying Ryzen Balanced, High Performance plans as well as Windows' Balanced & High Performance plans - Updating BIOS - Testing memory & CHKDSK - Turning off power saving type features in Windows & BIOS For context, there are a number of apps in the background that may or may not be relevant here, including Logitech G Hub, NZXT's CAM Software (RGB + Fan Control), RivaTuner, MSI Afterburner. AIDA 64 & NVIDIA Control Panel. I've probably tried a number of other things too but those listed above are the most important ones off the top of my head. If I've missed anything let me know, I'll be happy to provide more info if needed. If you have any idea what might be going on and how I can resolve this, I'd really appreciate your help Cheers in advance

Can anyone guide me in terms of picking a good motherboard for an AMD mATX build? Main purpose will be gaming however I do not plan on going too crazy with overclocking, but I would like a board which is somewhat futureproof. Plan on getting either the R5 2600 or 3600. Currently undecided between Asrock B450M Pro4, MSI B450M Mortar, MSI B450M Gaming Plus however I'm open to other suggestions and would be interested in hearing people's experiences!

Thanks for the input I will definitely consider the navi 5700 xt instead, though I did really want to build something with a little rgb bling. Might upgrade the GPU in a month or two once I have the aesthetics done, or vice versa. I don't actually have the case, however the whole reason I am looking at a new build is because I wanted to shift to a microATX setup which is something I've been wanting to do for a few years now. I found the case for ~$130 in Ireland and think it's worth it if I'm honest. I wasn't 100% sure on the motherboard so thanks for the recommendation. That board actually looks super nice and would go well with the overall colour scheme I'm thinking of! If I were to pick between either the Ryzen 3000's or a newer GPU, I presume you suggest going for the newer GPU with the 2600? I don't fully understand how bottlenecking works so it'd be great to hear your tips on that front. Thanks!

Ah, I didn't know. I'll keep on eye on that then, I live in Ireland and the price gaps seem to be higher here but I'm not sure about the 3000's. One reason I was opting for the 2600 was also because I read that there will be bottlenecks with a GTX1060 3GB. Any thoughts on that?

I'm aware of that but I don't really have the budget to splash out on the ryzen 3000...

Hi everyone, new to the forum here and wanted to get some thoughts on this MicroATX build I've been eagerly planning for a while now! Here's the build: https://pcpartpicker.com/user/dsp94/saved/#view=DxPQqs Bear in mind the PSU and GPU are from my current setup. I don't really have the budget to upgrade my GPU at the moment so I'm planning on keeping this as is. Would be great to hear your thoughts on potential compatibility / bottlenecking issues in case there may be something I'm missing or have overlooked. If there are any potential savings I could make that'd also be great to hear. Thanks guys!
