oc make games crash?
oc make games crash?
hello i really need some assistance
when i run the cpu stress test on my i5-6600k it works fine (oc to [email protected], stable)
when i run the gpu stress test on my Palit jetstream 980ti it also works (oc +250 core +500 mem, stable)
but when i try to run them together for about 5 minutes the screen goes black for around 2 seconds and then it comes back on, even though it was still responding when it was black (tested)
when playing games I sometimes see csgo.exe or bf4.exe stop working
and at times I get a BSOD (kernel security check failure or something similar)
i searched online and found this link: http://www.thewindowsclub.com/kernel-sec...re-windows
the guide suggested the same steps, but i still get a BSOD and think it’s the oc that’s causing this
cbench says i’m fine, prime95 says i’m fine for furmark, and prime95 for gpu shows 69-70c with +250 core +500 mem – everything seems stable
when my pc starts it works normally, showing the bios screen then booting into grub (dualboot with linux) and seeing windows
the task manager shows a task named vmi provider host taking all my cpu for the first 10-15 seconds
any idea what’s going on? i just want bsod to happen when cpu usage jumps from 60 to 99, then bsod again, but i didn’t have task manager open so i’m not sure
my antivirus (malwarebytes premium) seems to use a lot of cpu along with win defender
thanks in advance
There is no point in running prime95 once you encounter errors. Prime95 will automatically stop worker on that core and you will see less than 100% cpu usage.
From your tests so far, we can tell that it is fairly unlikely for there to be anything wrong with the ram or memory controller (breath a sigh of relief!). Failing small FFTs in prime95, we can tell that your cpu is not stable for some reason. The most likely scenario is that there is not enough voltage being delivered to the cpu. Prime95, in smallFFTs, will attempt to force your cpu to work at full load. At full load, the voltage delivered to the cpu will drop, as many parts of the cpu are demanding more power. This voltage drop is normal and is what we call Vdroop.
Now, back...
If OC leads to crashes, there must be an issue with your OC. It doesn't matter how it performs on Prime, furmark, or benchmarks. No tool relies on every feature of your system equally. Therefore, use the game that crashes as your stability test and address the problem in your OC.

I don’t usually rely on furmark for a real stress test; I mainly use it to check the GPU under heavy load. What kind of test are you running with prime95? It’s better to use smallFFTs instead of blend or largeFFTs, since this would give a clear sign about CPU stability. If it crashes or shows BSOD after just 30 minutes, it might mean the CPU can handle that frequency. It would also help to have something that lets you monitor system temperatures. I think a voltage of around 1.4V for the Vcore is roughly the safe limit on that chip; going higher could be risky.
Testing the CPU is just one part of a full stress test for overclocking. You should also run Memtest to check memory controller/northbridge or RAM issues. If you see errors, it could indicate low voltage for the memory controller, insufficient RAM voltage, tight RAM timings, etc.

If it crashes or shows BSOD after just 30 minutes, it might mean the CPU isn't getting enough voltage. It would also be helpful to have a tool to monitor system temperatures. I think a voltage of around 1.4V for the Vcore is quite high and should not be exceeded safely; going higher could be risky.
Testing the CPU is only part of a full stress test for overclocking. You should also run Memtest, which can help identify issues with the memory controller or northbridge, or problems with RAM. If you see errors, it could indicate insufficient voltage for the memory controller, insufficient voltage for RAM, tight timings, etc.
I'm planning to try running Memtest, but I already ran Windows Memory Diagnostic?
Prime95 was set mostly to blend mode; at 1.4V and 4.6GHz I tried to go up to 4.7 but stability appeared at 1.47V and then it exceeded.
The system temp monitor afterburner is doing a good job.
I'll attempt smallFFTs when I get to my computer (writing on laptop).
Memtest, prime95 smallFFT, 30 minutes, no BSOD... I succeeded.
Sorry if my grammar isn't clear; English isn't my first language.
By the way, at 1.4V temperatures are in the higher 60s.
I also found this from userbenchmark:

It's my system.
If it's the RAM or the northbridge, how should I fix it?
Locating mistakes during Memtest can assist in pinpointing the specific component causing problems. If the issue lies with RAM or the NB/memory controller, several adjustments can be attempted to address the errors. The simplest approach would be to boost the voltage for either the RAM or memory controller. However, this is rarely the case, as most overclocking attempts don’t necessitate such high voltages. More commonly, the solution involves adjusting the memory frequency and timings (such as reducing frequency and increasing CL, etc.).

The simplest approach would be to boost the voltage for either the RAM or the controller. However, this is rarely necessary since overclocking isn't usually required. More commonly, adjusting the memory frequency and timings—such as lowering the frequency and increasing the clock speed—is needed. Just noted the picture indicates I got XMP enabled with it disabled? Could it be related to XMP settings? The RAM should typically run at 2400 MHz.
XMP profile just ensures your RAM operates correctly at the specified frequency (such as 2400MHz). Generally, a single Memtest run is enough (though they recommend at least four); the problem seems unrelated to RAM or the memory controller since no errors were found. If you didn’t encounter issues with smallFFTs in prime95 and temperatures remained normal, it’s likely the issue isn’t system stability but could involve drivers, corrupt files, or other software-related factors.
If possible, consider moving all critical files to a separate drive and reinstalling Windows from that location. Afterward, performing an antivirus scan and using Malwarebytes would be advisable to check for hidden viruses or malware on the new drive. This approach may be quicker than troubleshooting drivers or file corruption.

Typically, one pass of Memtest is enough (though they recommend at least four); it’s unlikely to be related to RAM or the memory controller since no errors are present.
If you haven’t had any problems with smallFFTs in prime95 and temperatures are normal, your problem may stem more from drivers, corrupt files, or other software issues.
If possible, consider moving all important files to a separate drive and reinstalling Windows on that drive. After that, performing an antivirus scan and malwarebytes would be wise, especially if any viruses were hiding on the new drive after transferring files.
