First TIme in OC and some troubles

[Ros]

Crashing on the longer tests could be a build up of heat in the PC. Is your AIO pulling cool air in from outside the case? This setup dumps all the warm air into the case add to that there's likely very little airflow on the VRM section because of the AIO.
What kind of set-up do you have for the case/cooling?

I'm using a Corsair H150i Pro and a BeQuiet Silent 801 case..

OK, but you didn't answer the question about direction. I assume the AIO is in the top and your board is upside down from typical orientation??

I'm wondering if you get a dead spot down in the corner where the VRM are located which causes an eventual heat build up.

He meant the advanced section.... but it's not there.

It may be part of vcore... but cache overclocking doesnr yield much anyway.

Yes, the Advanced tab. But we were talking about AVX.

Yes My mobo is fliped upsidedown.
My radiator (3x120mm) is in front of the case, fans pushing air inside the case, 2 140mm on top exhausting air from the case, and 1 140mm exhausting from the back.

I removed the front cover of the case to improve air intake.

this is big picture of my case...




Maybe it's a dead spot, I'll use some smoke to try verify.

Well this the video of airflow in my case... seems there's airflow in the are of VRM, but passing through, not hitting directly.

Looks fine to me you have air flow passing over the VRMs.

Ok @wingman99, seems to be that my OC, at x45 is stable... the only difference is the cache multiplier... my firsts OC the cache ratio was in auto, and now is fixed to x40.
Is this factor so important? since every comment in this threat about the cache ratio it's almost non-determinant factor.

thanks

Cache will only really help in image/video editing and benchmark e-peen, for gaming you get 1-2 fps for more voltage/heat/stability issues, general consensus is "stick it manually at 4ghz/4.2ghz and forget about it"

Thanks Kenrou!
