Fix for stutters?

[Efussander 0]

good to know. thanks for that input. btw, I went ahead and changed the multi to 45. running like a charme as I write since 1 hour with prime. cpu temp around 76C, vcore is around 1.3V though. too high? will do some 'real' work now on the pc and later hopefully some flying. would be too funny if all I needed to do is raise the multi and nothing else. haha

Good! 1.3 is fine. =)

really? even better. things can be so easy sometimes. will see how it behaves over time but so far still no issues. Prime now for almost 2hrs without error. cpu temps still max 76c and I am even doing some photoshopping (actually w/ gimp). niiiice!

If you want to stay at 4.5, the next thing you should do is bump down the vcore incrementally until failure. Then bump it up one notch and that's the voltage you should run.

thank so much for your help, very much appreciated. will eventually report back in few days (and hopefully not already hours) whether my system remains stable at 4.5cheersphil

Phil, You might want to take a look at this guide also. http://www.clunk.org.uk/forums/overclocking/39184-p67-sandy-bridge-overclocking-guide-beginners.html

ha. that's the one I used, small world. except that I started with the 4ghz part and did not succeed for whatever reason. going straight for 4.5 seems to work for me. just finished 2 flights with the js41 downunder with orbx scenery and I must say I am impressed.

ethan, may I come back to this (off) topic. my 2500k still runs like a champ on 4.5 and I am really amazed what it is capable of. just 1 thing I noticed which (slightly) bugs me: my pc usually goes into standby mode after some time. however, when I want to wake it then in 90% of all cases it does not (re)boot straight away; the fans start humming but I see a black screen. no bios. no win7. what helps then is to press the power button for a complete shutdown. wait few seconds. push the power button again. luckily win7 the resumes like when waking up from standby. so no real issue as nothing is lost. but a nagging detail nonetheless. any idea? I know that I did not change any of the power savings option in the bios. in case you ask which sleep/suspend mode I use: no idea really. the pc goes complete black and quiet (fans off) except that the power led is slowly flashing and not completely off.phil

Sounds like you need a new bios.

Not true. ___________Phil,Glad to hear that you are enjoying 4.5. Pretty darn fast eh? This is a known issue. Ideally, you don't put your PC in standby. You should go to power options and turn off standby. It is much better to just shutdown/restart albeit not convenient at times. Nonetheless, there is a fix. Restart your computer, enter the bios, go to ai tweaker, find the line "Internal PLL Overvoltage". Set this to "Disabled". This should fix your waking from sleep issue. Please Note: Changing this setting to "Disabled" can inhibit the max clock that you are able to attain, and may even cause some instability at 4.5GHz. Like I said, the best course is to leave it enabled, and disable sleep/standby.
