Hello,

I've been having issues with my PC resetting while playing some games (Spellbreak, Rust) or streaming (HBOmax, Netflix). It does not crash during League of Legends or while watching YouTube). Some people have suggested a power supply issue (though I have a 700 w PSU). I ran the power test on OCCT. I'm not sure what it did but from looking at the temps/power/etc. it seems like it puts a lot more stress on the hardware than those games would. After the hour test, my computer never crashed and the test found no errors.

Would this rule out a power supply issue and probably an overheating issue?

It's my first time using OCCT's Power Test and tinkering with my new build Ryzen 7 5700x and Colorful RTX 5060 Ti and CoolerMaster MWE Bronze V3 PSU

Everything starts great and steady during the first 3-5 minutes, afterwards, the stress test just goes up and down (the CPU and GPU power, see the encircled image in green), and I can clearly hear the fans constantly lowering and increasing. Is this normal for OCCT's Power Test? I'm not experiencing any errors and crashes, but the up-down pattern of the test and graph kind of feels weird

What are norms temps after a minute?

My cpu jumps to 80C right away then after abt 1-2 mins is mid 90s and going up so I stop it. Is that normal?

Hello, I have a few questions about OCCT as a stability test. How reliable are these tests? I was testing my GPU overclock using the 3D Adaptive "extreme" test, testing various overclocks. I set +200 on core clock and +1500 on memory clock in MSI Afterburner. Other benchmarks and games were always stable but as soon as I ran the OCCT test it showed me a lot of errors. So I decreased core clock to +150 and left memory clock at +2000 and let it run for another half hour. This time I had no errors. Does this mean that my first overclock despite being stable in games was indeed NOT stable? And does that mean that my second overclock now should be in fact stable as there were no errors?

Hey everyone,

I have been using OCCT to check my temps under high stress. I recently got a new case with more fans, and also got a new CPU cooler (both the case and CPU cooler are from Be Quiet). While doing a stress test my CPU temps don't exceed 73 degrees celcius, but they mostly max on 71 degrees. Might be nice to tell that it's the I7-8700K with a Be Quiet Pure Rock 2.

I found an option to test my RAM, which I tried out. Then I found one for VRAM, which I also tried out. Both just for 1 minute, nothing special. Then I noticed a test for 'power', which I figured might test how much watt my pc was using or could be using. While also doing this test for a minute, I noticed my temps going all the way up to 97 degrees celcius at its max. This did worry me a bit, as my temps don't even get close to that while my PC is running intensive games or whatever.

As it might be relevant, my PSU is a CorsairVS650, which for my I7-8700K and GTX 1060 6GB would definitely be enough, never had any issues in a few years time. I would just like to know if this test should make me act, or if there's some logical reason why only this test manages to get my PC this hot.

My pc was (is) crashing (by which I mean not BSOD, just hard reboot, then RAM checks), so I took it to a repair shop (I have neither the tools nor time to fix it myself). I had run several tests because it was crashing when the GPU was maxed out in some applications, and so I tried several OCCT's tests, and then I got to the power test, which caused it to crash pretty reliably near the 3 minute mark.

They came back and said they'd run the OCCT stability test 3 times, and it was fine, and that there was software issues that they fixed (new GPU drivers and windows repair). I brought it home, ran it for a day, and ran the test again after that, and it crashed again. Windows event logs say WHEA error, but nothing else. Literally only the phrase "A fatal hardware error has occurred. a record describing the condition is contained in the data section of this event." Which is lovely, because I don't see any 'data section' or further info. The CPU temperatures got HOT under the power test (100c the entire test time).

I set the power test to run for 5 minutes. The shop said they got a stability certificate. Are they wrong? Is the issue on me somehow? The PSU is 1000w, which should be overkill for the i7 and 4070ti. I don't overclock, the DDR5 RAM is XMP'd to 6800 (it's own XMP, I didn't choose it or anything), but even when I dropped it to 5600, same result.

What do I do/test/try/complain about? Thank you in advance.

Hi what test should I run on a new pc/build that everything is fine and is the 1 hour enough?

Hi, done a general 1hr power test a couple of times and it threw this both times. No idea what I'm doing.

Hi,

Recently, I tried to launch a new Power Test on OCCT, and to my surprise, the PC shut down abruptly just 2–3 seconds after the test started.

I was quite surprised because I've already run multiple Power tests in the past without ever crashing. As far as I can remember, I haven't changed anything in the BIOS or inside the PC that would cause a sudden shutdown like this.

I tried running the other OCCT tests — CPU, RAM, and 3D Adaptive — and none of them crash.

Naturally, I'm starting to suspect the power supply, but it's a Lian Li EDGE 1300W, which should be more than enough. I also don’t think it’s defective, since I have no issues during heavy 4K gaming sessions. It's just oddly loud, the fan behaves strangely — but aside from that, it seems okay.

So my question is: how can I determine if this is caused by the PSU, the motherboard, or even the CPU/GPU?

When the crash happens, the last OCCT window shows no overheating on either the CPU or GPU. The PC doesn’t rebootn, it’s a complete shutdown, with all RGB and fans going off instantly, within less than a second.

Here’s my build:

CPU: 9950X3D

GPU: RTX 5080 AORUS Master Ice

CPU Cooler: NZXT Kraken Elite 360 V2

RAM: Corsair Titanium DDR5, CL30 6000MHz

Motherboard: MSI X870E EDGE Ti

PSU: Lian Li EDGE 1300W

SSD: Samsung EVO

How can I identify the problem and be sure if it's the PSU, the mobo or anything else? Sadly, I don't have other component to test...

Thank you in advance!

Hi all,

I've just downloaded OCCT today after trying to find the root cause to a PC crash/restart I've been having, and now OCCT causes my PC to immediately shutdown when running Power test.
I built the PC with all new components (expect from GPU which I have since replaced and still experience the issue).

PC Specs:

Case: Phanteks P400a
Motherboard: MSI Meg Unify X570
AIO: MSI MAG 360mm
RAM: Corsair Vengeance RGB Pro 32gb (2x16gb) DDR4 3600mhz (with 2 light enhancement kits)
CPU: AMD Ryzen 9 5900x
GPU: XFX Speedster MERC Radeon 6900XT (Black edition)
PSU: CORSAIR HX1000 Modular ATX PSU - 1000 W
GPU Support: UpHere (G276ARGB)
Storage:
Sabrent Rocket Plus 1tb NVME M.2
6TB HDD and my old SSD's (500gb + 250gb)

PC Crash/Restart:

My PC randomly restarts when playing COD Warzone. I don't play many other games but often working on the PC for 9-11 hours a day before playing games and never had any issues.

This has been happening since I built the PC in December, and has happened around 6-7 times now. It's really inconsistent as to when it happens and I've not been able to pinpoint it to an exact action/scene in-game.
There was a period since perhaps late March after I changed some settings (disabled power-saving mode & turned off automatic Windows updates), but has now come back and happened twice in the last week.

I received an event log for today's crash which was:
'Event 41, Kernal Power' - "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

Following that information, I eventually found myself with a potential PSU issue which is where I discovered OCCT to perform some stability & stress tests, which is what's lead me here with my PC immediately shutting down when running a test.

The exact steps were as followed:

• Downloaded & installed 'OCCT PERSONAL STABLE (x64) 8.2.1' from ocbase.com

• Launched the application

• Bit of navigation and research to figure out what I needed to run. No settings were changed.

• Under the 'Test' page and 'Test Schedule' menu, selected 'Power'.

  • Instruction set = Auto

• Selected the large red button to run the tests

• Presented with a popup related to the Pro version and directed to a web-page to be able to continue to execute the test

• Hit the red button again to begin the test

• PC turned off

• Waited patiently incase I missed a prompt/warning notifying me that the PC would turn off, but after about 5 minutes nothing happened

• Tried to turn on the PC to no avail

• Turned the power switch on the PSU off & back on

• Tried to turn on the PC to no avail

• Repeated power switch step whilst also unplugging PSU cable and then replugging

• PC turned on as expected

If any one has the answer to the PC Crash/Restart issue then I'd happily propose to you, but mainly looking for advise and support on the OCCT issue and why it turns my PC off completely and why I have to unplug & plug PSU cable back in for it to turn back on?

Thanks in advance <3

Hi, recently my pc is having random restart while i am playing video game,

i ran the power stress test and my pc restart after 5 minutes,

I thought this maybe my psu problem, so I upgrade to higher watt

I ran the power stress test again and the issue didn't fix that my pc restarted again

since the issue happen in the new psu, are there other possible factors that making my pc random restart?

Thanks

Hey guys, nowdays I noticed that if a game uses a lot of CPU or GPU I can't really run it consistently. the FPS itself if great, but every 4 to 5 seconds everything (including cursor and the sound also glitches out) freezes.

Ran on OCCT power test and these are the results. As you can see after about 20 sec of heavy load, these drops happen. Do you think my PSU is dying?

(Shouldn't be the temp cause CPU nor GPU goes above 65-70°C)

i7 13700K+rtx 4080=Kaboom 850W thor psu😅

TL;DR

Problem: (1) Frametime spikes frequent every few seconds, looks like microstutters in game. (2) Freezing and Non-BSOD crashes/resets at random times.

OCCT Results: All tests passed except power test, which leads to a non-BSOD crash in a couple of minutes and kernel power error 41 in windows events viewer.

Specs: At end of post

Need: Help :(

Hi all, I've built a new PC and I've been trying to figure out for the past few days what's causing some issues. I've attached the specs to the end of the post.

Issue 1: Frequent extreme frametime spikes (a 400ms spike followed by some 40-50ms spikes seems to be the most common), which manifests in micro-stuttering every few seconds in games. The game, say Cyberpunk 2077 or Hitman 1 (there's no way a game this old should cause stuttering right?), would start off fine, but after 30seconds to a minute of playing, this would start.

Issue 2: Frequent non-BSOD crashes that come to a pc restart, this would happen seemingly randomly, during both gaming and light web browsing.

I was down in the dumps for days, but in my darkest hour, my wonderful girlfriend found OCCT, and I've been using this to do some test.

The CPU test was first, and it instantly spiked to 95c and stayed around there. I was at first alarmed by this, but I think this is normal (?) The small dataset test passed through 10 minutes without other issues.

The 3D-Standard test, memory test, and VRAM test also finished through 10 minutes without any problems.

The power test would not pass. My pc would crash and restart after a few minutes on the power test, every time. I even tried everything with the integrated graphics and it still failed. Events Viewer shows a EventLog 6008 followed by a kernel power 41 critical error at the same time of the crash.

How would you interpret this issue? Does this mean the PSU has been the culprit of all of these issues? Might it be the power system in my house? (The house i'm in right now is very old.) Could the open-box gpu be defective?

PC Specs

CPU: 7700X

COOLER: Noctua NH-D15

MOBO: ASUS TUF X670E Plus Wifi

RAM: G.Skill DDR5 6000

GPU: Gigabyte Gaming OC 3080Ti (open box from newegg)

STORAGE: WD_Black SN850X

PSU: Super Flower Platinum SE 1000W

CASE: BeQuiet 500DX

Other things to note:

1. In MSI Afterburner, the frametime spikes also coincide with voltage limit, power limit, and no load limit; not perfectly at the same time, but they seem sporadic when the frametimes are also spiking. Not sure if this means anything.

2. I tried playing things with integrated graphics. No frametime spikes, but that could just mean the PSU isn't demanding as much power, right?

Edit: Lowered the power limit % and the max frequency % in AMD Adrenaline (under performance>tuning>click custom) and it no longer restarts. Bought an FSP Hydro G Pro Gold 850w and it no longer restarts when I reverted gpu settings to default and my rig now passed all the stress tests. Thanks to everyone that answererd!

Hi! I've been trying OCCT to check my GPU since recently after playing for awhile or if GPU is under heavy load my pc would crash then reboot instantly. No warning or blue screens just black screen then restart. I tried the OCCT 3D standard test after cleaning my pc and it worked but then I tried it again for a second time then it crashed/reboot again. I also tried the Power test and it never comes through as it immediately shuts down then restarts. I've been gaming with no problems during the past year but recently this started happening. Any ideas? Also I haven't overclocked anything since I don't know how anyway, but upon checking my cpu its always on high clock speed but temps are normal. My PC is only 1 year old with brand new parts except for the GPU which I bought 2nd hand.

I'm wondering could this be a PSU or GPU issue?

Specs:
CPU: Intel core i7-11700

Mobo: Msi MAG Mortar B560m wifi

GPU: GIgabyte Radeon RX 6700 XT Gaming OC

PSU: Cougar 600 80+ true rated (Non-modular)

RAM: Team group ud4-3200 ddr4 (16x2)

Cooling: NZXT Kraken x53, Arctic p12 x 3

Hi folks.

All of a sudden my PC has started powering off (no blue screen), all components switch off and then restarting like nothing happened. This started yesterday.

I read that testing my power supply with OCCT might shed some light on it but I'm unsure what I am looking for in the results to tell me what's happening. I set the Power test to 1hr but it can't even complete more than 8 minutes before it does exactly the same thing it has been and turns off.

Can anyone advise?

I never once black screened or got BSOD, the only thing that came up was one error on core #4 so I toned it down to -40. Will be trying to address that error in the future, but for now who cares. Nothing I do with my PC has a problem with my undervoltage. Be nice and civil next time. The title of this subreddit is literally " All things overclocking go here. Learn to overclock, ask experienced users your questions, boast your rock-stable, sky-high OC and HELP OTHERS!" Not bash on others for not having enough proof with only Cinebench and Prime95 tests. Sorry that I got a good CPU? We're all people here. Have some respect. Just because I'm not a fan of the bench program doesn't mean I'm wrong. Lots of people have damaged their components with that program. It's the most stressing benchmark program for a reason.

3 back to back tests on each. I did a total of 4 of them but I didn't realize I did the same one at the end. Thought I chose FIXED instead of AUTO. First and 2nd one are with -42. The last one is -40. Also, the only thing I did different was turn off XMP.
