Overclocking not going so well, help please.

lewis2701 · 25 Mar 2012 at 13:47

Firstly, I tried the auto overclock feature on my P8Z68-V. This got me to 4.4ghz, but it BSOD after 45 seconds of Prime95. So I tried manually overclocking, read the guide on here, watched many youtube tutorials and also visited other forums for help. I did a multiplier of 46 and and a CPU voltage of 1.35. I also tried a few different variations of this, so for example, changing the multiplier and CPU voltage in little increments but each time it ethier, BSOD's before I can enter my password, BSOD's within the first 10 seconds of IBT/Prime95 or gets stuck on the windows loading screen. And yes I changed LLC etc. Just tried the auto overclock feature again and the screen just goes blank and goes to standby like there is no imput from the PC at all. Anyone got any advice for me?

So I should just leave the voltage on offset mode and set it to 0.005?

wazza300 · 25 Mar 2012 at 14:38

yes but set to +10,if you read that thread further im using +10 and high llc

lewis2701 · 25 Mar 2012 at 14:39

So you mean instead of 0.005 use 0.010?

wazza300 · 25 Mar 2012 at 14:42

yes,you can try +0.010 first,then test for stability and try lowering to 0.005 later

lewis2701 · 25 Mar 2012 at 14:45

okay cheers.

wazza300 · 25 Mar 2012 at 14:51

btw what cooler are you using?

lewis2701 · 25 Mar 2012 at 14:57

Corsair H60 + I just did it, ran Prime95 for 4 minutes. Temps went to 85C and it was using 102w. What shall i turn down to lower temps a tad?

wazza300 · 25 Mar 2012 at 15:00

could try offset at +0.005 or a lower llc level,max i get temp wise is 71c with a noctua d14 air cooler

Do you have a single fan on the H60?

lewis2701 · 25 Mar 2012 at 15:14

Yeah, just a single. Have a spare I could attach for push/pull. Might do that. Just set to 0.005 and highest temp was 86 and it bsod after 6 minutes?

wazza300 · 25 Mar 2012 at 15:16

in prime95? seems awfully hot for prime,if it was intel burn test id understand

try attaching two fans in push/pull,i was only getting 79c-85c with an akasa nero s cooler and a single fan

lewis2701 · 25 Mar 2012 at 15:17

Why is it BSOD'ing so soon though?

jamesfreddie · 25 Mar 2012 at 15:17

Do you have some spare thermal compound?

probably because not enough cpu voltage,im only going off my chip but i need +0.010v and high llc,with that im 100% stable in intel burn test and prime95

everything else voltage wise is left on auto

in total around 1.36v for 4.5ghz at full load and thats including offset and what llc applies

lewis2701 · 25 Mar 2012 at 16:05

just got another fan added for push/pull. ill retry 0.010

lewis2701 · 25 Mar 2012 at 16:31

Ran Prime95 for 15 minutes and hottest it got was 85C. Although it would be on 77/78 for 2 minutes then it would jump up too 84/85 for a minute. I know this is not what most people would consider a long run, ill run it for an hour tomorrow. Thanks for the help.

wazza300 · 25 Mar 2012 at 16:36

thats about right for that cooler,depends on your case and ambient room temps too,but 85c is about right,it wont get that hot in gaming/normal use ect
