ASUS X99 Strix: Overclocking issues !!!!!!

[link93300]

Hi,

I have an Asus X99 Strix motherboard with an Intel i7 6800k.

When I overclock my processor (4.3Ghz 1.39V), my OC is very stable, I can run Prime95 + OCCT + 3Dmark firestike physics at same time and I have no crash. The next day, everything work, but for example, the 3rd or 4th day, when I boot my PC, nothing works, my OC is unstable, I need to reboot the computer several times that my OC is stable. I also have this problem if I do a 4.2GHz OC to see even 4Ghz with or without XMP ...

I have the latest version of the BIOS, my PSU is a corsair RM850i my cooling is a Corsair H110i GTX and my RAM is TridentZ 2x8Go 3200Mhz.

With this motherboard I have many issues to overclock my CPU !

Can you help me to solve this problem ?

Thanks

Yes.

Your overclock isn't stable. Stability extends beyond running stress programs. Daily usage is the best test for a stable overclock. So continue tweaking. 🙂

Today I could do a stress test of 2 hours, OCCT + prime95 no AVX instruction + 3dmark at the same time with the same settings. I don't know why I've some boot instable after 2 secondes of stress test, but a simple reboot and I can made a 2 hours stress test ... so are you sure my OC isn't stable ?

No error. Since my topic, I have no issue.



Sorry for my english I hope is readable lol I'm french ^^

So this morning same thing, overclocking instable at the first boot of the day OCCT or prime95 crash after 2 secondes ... To solve it I just need to shutdown my computer and restart it. Currently OCCT and prime95 runs since one hour ....

I'm sure that the problem is the motherboard (or bios) and not my overclocking ...

Yesterday: 2 hours of stress test with occt + prime95 => OK
This morning: 10 sec of stress test with occt => Crash
5min later after shutdown and restart computer: +1 hour of stress test with occt+prime95 => OK

A simple shutdown and not a restart solve this issue. :mad:
I'm in peace until the next cold start in maybe 2 or 3 days.

Today: This morning (cold boot) nothing works, I just shutdown my computer and turn on to fix that !

Try use a other bios, to see if it fix it 🙂

Does it happen if you have a overclock of 4Ghz too?

Yes I have the same issue for any overclocking. I'm waiting the 0801 final release (beta actually)

Well yea, then is a Bios issu 🙂 just wait or try a older bios.

Did you ever increase incremental voltage of Vcore by +0.01V (1.4V...1.45V, V<1.5V) before you stable? Did you set the memory to XMP or manual configuration? The best is to set the memory to timing from the specifications

Hi !

Yes sure, I've increased my Vcore by +0.01V actually I've set at 1.39V for 4.3Ghz if I set my Vcore to 1.38V OCCT or prime95 or games freeze.

I don't have the best 6800k sample but it's correct for a 6800k.

I've overclocked the memory cache of 200Mhz and increased Vcache and Vin until stability (+0.01V)

There are some screeshot of my bios here:

I would not be hesitant installing the bios just because it is classified as beta, it is released on ASUS official site
