With a post that detailed, I'd at least expect you to be typing on a mechanical keyboard. biggrin.gif

lol iknow i do most of my posting on my iphone its a nightmare but its a great forum to check while your mobile ( or when my girlfriend puts me on the sofa with the cat, such as the current situation) ive got a crap keyboard too lol. im prone to breaking them so just buy cheap ones. ive got a great single handed game pad tho for fps games. its a razor nostromo.

Thread Starter 
Update: I haven't had time to check the thermal paste application or to retry the overclock with manual voltage settings, but I thought I'd just post some stock temps.
So, stock i5 750 @ 2.67Ghz with CPU-Z showing around 1.024 core voltage:
No load: 31 degrees
Load: 52 degrees

Are those temps normal? A techpowerup review with the same i5 750 setup was showing a 23degree no load temperature and the same load temp (52 degrees). However, their load vcore is at 1.25V while mine is at 1.024 so...

http://www.techpowerup.com/reviews/N...U9B_SE2/5.html

They do say that the cpu is left to idle for an hour before taking the temp which I haven't done, but it's still a pretty big difference. What's confusing is that the load temp is almost exactly the same, although mine was at a much lower Vcore.

Anyway, I'll probably have some time tomorrow to try slowly oc-ing with manual vcore settings and hopefully get some better results.

that is very low and i doubt its right. at stock and idle mine is under 1v, then load it really goes up to 1.215v or something. make sure you set the vcore and vtt to normal rather than auto while testing.

one more thing, i dont know if this applies to 1156 for sure, but your supposed to keep vtt voltage within 0.5v of the ram voltage. so if you happen to have 1.65v ram like me, you should set 1.15vtt at least, just to be safe. this was a bit of an issue to find out, as turning on x.m.p profile (if your ram has it) set my ram to 1.65v without altering the vtt, however it had 1.15 greyed out somewhere.

might have been overriding by itself, but just incase it wasnt i set it manually anyhow.

It must be your thermal paste application, or the voltage is really getting boosted with the auto settings, you would probably be best off manually OCing your cpu.

for comparison (my sig rig check my link to see the case, airflow isnt that amazing and Im using 800rpm silent fans, a massive gpu cooler that dumps heat into the case, and a hyper 212)

i5 760/3.79ghz/1.22v/ambient of 21c

idle at ~28c on all cores
5 mins of linpack ~50c

I highly doubt your thermal past application is that bad, I really think the auto OC and load line calibration is whats causing your issues, as auto voltage adjusting in my experience has used way too much voltage

The heat in Melbourne is killing me (and the computer.) Anyway... remember that at time of testing it could've been Winter there. The temps should be fine depending on your ambient temperature and how well your case is ventilated.

Update: I checked the thermal paste application and while it wasn't perfect, it was decent.
I re-did it with the credit card spread method and I'm getting the exact same temps so that pretty much rules out the paste as being the issue.
It could be the relatively crappy air circulation in the case (due to the size of the case), even though there are 3 fans.
I'm about to try the manual overclock method to see if I can get the OC temps down that way.

Will update when I get some results.
