Reducing VID

[Bearded1]

Hi all. How's it going? I recently bought some new shiney to replace my 9 yr old A64 x2 box and been slowly getting my head round

overclocking and how it's changed from what u had to do with old hardware. Now closing in on my 24/7 overclock of 4.6GHZ. The only thing is

it needs 1.315v to be stable at that speed. Temps are good, peaking for seconds only at 68-70 degrees across 48hrs and most of the time in

high 50s. Passes all stress tests that i've tried (IBT 25 passes, Aida64 9 1/2 hrs, Prime95 v26.6 8hrs, Intel XTU 6hrs.) at 1.295-1.3v but when

left running BOINC it'll bluescreen with 0x124 or 0x9c after a few hrs and neeeds that extra little tickle to stay up. I'd like to get it stable at

1.3v if at all poss. I know it's only 15mv over with reasonable temps but it keeps nagging and scratching at the back of my mind. (I have been

known to exhibit OCD tendancies.) Does anyone know of any tips or tricks to try? I'd rather have it stable at that voltage/speed and leave a

little performance on the table than extract everything i can from it. Everything is at stock speed and volts apart from core clock @46 1.315v

and cache @41 multi with +75mv offset. I've tried various levels of LLC and they seem to have no effect on the VID under load as read by

coretemp.

System.
Core i5 4590k
ASUS Z97-P
24GB Crucial Ballistix 1600Mhz
250GB Crucial BX100
Radeon 4850 1GB
Rajintek Tisis cooler
Seasonic 350w Bronze
Assorted old HDDs and fans.
Any other info needed pls let me know.
Cheers

Why do you type like this?

Anyway, you can't make the CPU more stable than it already is. If you need 1.315V for 4.6GHz, then you need 1.315V for 4.6GHz. If that's too much for you, all you can do is reduce the frequency to 4.5 or 4.4GHz.

I agree with techhog. BTW is your psu sufficient?

 

[Bearded1]

It looked fine when i pasted it and previewed. The psu is more than sufficient for this system. Never seen it pull more than 240w from the wall and that was running 3Dmark and crysis benchmarks while also AIDA64 or XTU stressing. I was hoping someone who has a better idea than me about how different bits of the cpu interact could chip in. For instance would dropping the cache back to stock speeds give me any more room to play with?
