Strange Overclocking Result w/ 9700K

Having a situation with my 9700K w/ my Aorus Pro motherboard I'm hoping I can get some perspectives on. So I've gotten my 5ghz (@1.35v) OC to pass 1) Prime95 (non-AVX) overnight, 2) TimeSpy Stress Test for 3dmark (EVGA Hybrid FTW3 2080ti OC'd), and 3) mem test for 8 hours (corsair ballistix @3200MHz ). Both games I play (division 2 and wildlands) that tax the system run absolutely fine for hours.

Yet about every other day, just twiddling in windows, the computer has either hung or BSOD with apparently nothing stressful running. I've got good cooling (GPU loads at 55C and CPU at low 60s). I've turned off all the power saving features and set it on Turbo in bios.

I'm head scratching why my system has hung when I'm "doing nothing."

Are you sure windows wasnt corrupted during the ocing process?
Is your memory oced or stock? Ive had oced memory cause issues despite passing memtest86. Giving it a bit more voltage or loosening timings may help.
Giving the cpu a tad more voltage may also take care of it.
Also checking the psu connections for a loose wire may help. Do you have a known working psu to test with?
Thats all i can think of right now.
Good luck!

Your problem is the RAM...........Crucial makes Ballistix.

Corsair makes Vengeance and Dominators.

Although the problem could rely on the power supply, have you used both EPS connectors, just in case. Plug the 4 + 8?
With the 9600K it would be fine, being that it's a 6 core proc, whereas the 97 is an 8 core proc.
I haven't used both because I heard on some forums that some have found it to fry their chip. BS?

I've never heard of this happening. I have however seen board instability on mobos that had dual EPS connectors and we only plugged in one.

The chip should have several years of warranty through Intel. I wouldn't worry about frying it.

Your system technically never does "nothing." You should check your event logs to see if there are any clues as to what's going on.

This is doubtful. I've run the Core i7 9900K @ 5.0GHz with a single 8-pin power connector on the motherboard without issue. Electrically speaking a single 8-pin power connector can provide far more power than you would generally need for your CPU, even highly overclocked. I actually think the dual 8-pin connectors are for crappy power supplies. Manufacturers have to consider that sort of thing. Similarly, NVIDIA would tell you that you needed a ridiculous amount of power supply for some of their cards and the reason was because they were accounting for crappy power supplies with ratings that are more wishful thinking than a measurement of their capabilities.

I have literally never seen this. I've tested probably about 200 motherboards at this point without ever seeing that.

Again, I think this is shoddy PSU's that are responsible for this.

Maybe in some cases but we pretty much stick to Seasonic and Corsair PSUs. I think it had more to do with the shitty Sabertooth mobo someone bought when I wasn't here to order good parts lol. iirc the manual even warned of instability if you only use one. An EPS Y cable seemed to resolve the issue, but I agree with you that 1 connector should have been sufficient as the Y cable does nothing to actually deliver more power.

A Corsair unit isn't always a good thing. It depends on which model we are talking about specifically, and who actually made it. Seasonic is of course excellent. As for the Sabertooth, it would depend on the generation as to whether or not it was actually shitty. Older Sabertooth boards were pretty awesome. The ones made in the last couple of years, not so much.

Prime95 (non-AVX) overnight,
You didnt test all of your CPU and are having issues
Try testing all of your cpu

also I dont see a psu load testing kaa prime95 blend + furmark

is a classic mistake to only test component individually and not combined


in case its windows corruption
sfc /scannow might help a bit

Plugging in both EPS12v connectors keeps the CPU +12v slightly higher. Multiple people with Gigabyte boards that have VR HWinfo monitoring have observed this. Going from 11.781v to 11.908v has no side effects.

That may be true, but I've never seen enhanced stability from actually using both connectors.
