860K stable @ 4.6Ghz - Can I go higher?

post #1 of 9
Thread Starter 
So, Been fiddling round with my settings and now have my 860K stable at 4.6Ghz. Left it running prime95 and all good!

I have this paired up with a GTX 980, and am pretty impressed. GTA V is at max settings and it stays mainly on 60fps with the occasional spot in the mid 50's.
Same story with Just Cause 3, but that has trouble holding 60fps during fights, generally during a gun fight hovers between high 40's and mid 50's.

So, Can I go any higher??? Am using a Corsair H100i GTX cooler.
Here are my settings:

In my FX-8XXX chip safe voltage is around 1.55v. I´ve been using 1.47v for some 3 years now, and everything is perfect, no degradation.

Your CPU may have the same specs, but i dont have sure. Anyway if temps are good, socket and cpu temps, you may be able to get more 100~200mhz out of it.

At this 4.6ghz clock, it is already a good overclock you got there. Happy day !

Make sure your VRM and Socket temps dont throtlle your CPU in heavy load.

Since you have a GTX980, quite overkill GPU, the higher you clock the CPU, the better.

Good Luck !

I don't have an 860k but from lurking in their threads it seems that anything over 1.5 volts will degrade the cpu. I hope someone who knows will wander by soon.

1.49v is the limit I've been told, beyond which degradation will occur. 1.52v for 4.6 isn't great, but it's better than what some chips can do. The only way you're going to go higher is to improve cooling drastically, and you will only buy yourself another 100 mhz doing so. If you go LN2, you may get 600 MHz but really, that's just for suicide runs.

Wasn't there something about performance/Mhz scaling poorly beyond 4.7 on kaveri? Beyond that it wasn't really worth pushing further for daily use.

Thanks for your input guys All comments and suggestions much appreciated :-)

So now have reduced voltage increase to 0! (if i leave it on Auto, the motherboard will up it)



Done a 10 minute Prime95 test and ok so far, but will keep testing!

Well,

In my opinion, regarding overclocking, AUTO options in BIOS never are the best option. As always have been about this subject.

The best way is you be in control of the vCORE.You never know what crazy voltage motherboard can use.

Goog Luck !

EDIT: You could increase the voltage

10 minutes? Two hours is about right for a decent stability test.

Erm, I know lol
That's why I said "ok so far but will keep testing"

With some settings i've tried, the PC has completely crashed to a bsod within seconds of starting a stability test, so 10 minutes is a good sign!
