2500k voltage issues

post #1 of 7
Thread Starter 
i have a 2500k in asrock extreme4 board and it would not get stable at 4.7 Ghz even at 1.435V. not stable i dont mean BSOD with x124 or x191 code, but when i run prime95 it gives me an error for the forth core "rounding was 0.5 expected 0.4" and when i play high graphics demand game like bfbc2 it will froze in the middle of the game and gives me a static noise, but no BSOD.( i wonder if its my graphics card)
is 1.435V kind of high for a 2500k OC?

That means it's unstable, mate.
You don't always get a BSOD.

Try lower bro.... mine only needs 1.34v in bios just to pass 12hours prime blend test....but when underload it goes up to 1.368v.

Is it always on the 4th core?
Or is it on random cores?

And how many times have you gotten that error?
You should BSOD occasionally, though.

But if it's never a BSOD, then that leaves you some room to work with; you can try changing the RAM timings or ram speeds, tweaking the VTT or the CPU pll voltage.

You said BC2 gives you a freezing with static noise...this sounds like this is IMC/RAM related, cuz that never happens to me; I just BSOD in that game.

Are you sure its not your ram?

When I got rounding errors in prime 95 testing my sandy bridge rig, it was because I didnt have enough ram voltage.

Some boards default ram to 1t even though supposed to run at 2t and thus, the ram isnt receiving enough voltage to run properly.

I dont know if 1.432 is high on average, but mine needs 1.452 under prime 95 at 4.7
