I've just finished putting together the new system....... I upped the mutliplier to 45 for now.... set a manual 1.25vcore and I'm having BSOD at times when playing Rise of Flight. I haven`t installed FSX yet as I don`t want any dissapointments,Ram timings are set to 9-9-9-24 2T (Auto) 1.5vI`ve been following this guide http://www.clunk.org.uk/forums/overclocking/39184-p67-sandy-bridge-overclocking-guide-beginners.htmlI could use all the help I could get really. I havent had much exprience with overclocking but I`m learning. I just bumped the vcore to 1.26 to see if that improves stability, as per that guide saying 1.25-1.27 at 4.5ghz... Last night I set the ASUS Optimal overclock and went to Walmart and when I got home I had a black screen and it wouldn`t POST, I had to reset the cmos jumper to get back into BIOS. During the stress tests my CPU went to a max of 48 deg C...and I`m in a cold basement room.Any input or constructive critism appreciated at this point... I haven`t enjoyed this system yet but I soon hope to.

Did you test your stability with either Prime95, Linx or similar program?

Prime 95 but I only let it run 25mins... maybe I didn't have that program set up right either?

It is essential that it starts on all cores, you basically see it running in more windows.1.25 seems very very low.25min is WAY TOO SHORT.For a successful overclock you need to have at least couple of hours stable, without crash. As long as it crashes, you need to up the vcore.Also check your 0x0000... number on the blue screen if it appears and note it.

Thanks Word Not Allowed..... Just out of curiousity what is your Vcore with a clock of 5GHZ? I won't be trying to get anything over 4.5ghz.

1.53. But mind that I have custombuilt watercooling loop.

I'm going to bump mine to 1.27 and run Prime95 before I go to bed.

Nice profile pic. You beta testing Flight? :LMAO:

That clunk guide seems to be off. I don't know if got some of the very first units produced.. but his vcore is waaaay low for even systems that have capable chips. Mine is not and the best it will do is 4.4GHz at 1.356v

Haha.. My grandfather restored 3 of them in the 1980 's, and this one still remains here on our farm. One of them is out in British Columbia right now being restored again (was involved in a crash), and the other is currently flying in Australia.

Also, with overclocking comes the temperature rise. What is your highest temperature on initial P95 run?

It was max 48-49 celcius using Realtemp 3.60

I would recommend you go 1.3 fixed, and run it, see how it holds. I doubt it will, but you can safely go 1.25->1.3.

What do you mean? You think it will crash or heat up ?

I think it's gonna crash even with 1.3, because as Ryan said before, 1.25 stable for 4.5 is like... nearly impossible.I usually do the testing when on the computer doing other stuff like browsing or so. In the background...
