I have my ram at 1600mhz so I bumped that to 1.6, but the VTT I left on auto.
How is it lower than stock?
I'm wondering what voltages I will need for 167 blck and Turbo on. Let's hope anything below 1.3V

Received my i5 750 yesterday and managed this..
temps were around the mid-high 60's when running Prime.

Guess i should add this is on board in sig as Gigabyte got returned due to duff mem slot!
The mem needed a lot of pressure to seat it which could have contributed to
the slot going bad and would not boot with 2 sticks first off....where the asrock memory slotted
in very easy and booted both sticks 1st attempt.

Just got my i5 750 today. Using a GA-P55-UD5 board and H50 cooler. I was a little concerned by the slightly toasty temperatures at load so I may have to cut back to 3.8ghz.

I tried reducing the vcore a notch and it became unstable. I'm not really happy to run at temperatures in the mid 70's so I've done a bit more fiddling around this morning. Added to that and having read some of the previous posts in this thread I'm uncomfortable with increasing the QPI/VTT past 1.1v (especially on brand new kit which I've forked out a fair few quid on )
I got these results at 3.8ghz with 1.2v core and 1.1v QPI/VTT. I know it's not quite the 'magical' 4ghz but I'm happy to trade off the extra 200Mhz in exchange for not turning the inside of my case into an oven.
Should also point out that I'm missing one of the top exhaust fans from my case (Fractal R2) because it arrived DOA, so I may see a slight improvement once that's installed.
Load under Intel burn test (highs of 66C-67C)
Then back to idle

OK, I know I said earlier in the thread that I'd be satisfied with 3.8ghz. Well... I lied
Not sure what I was doing wrong yesterday but I've re-seated the cooler today as one of the cores seemed to be running 8C-10C higher than the others.
I've ran IBT and didn't encounter any problems (max temp was around 70C). Just giving it all a going over with Prime95 at the moment with these results so far.

If it makes you feel safer the max for VTT is 1.21I'm uncomfortable with increasing the QPI/VTT past 1.1v (especially on brand new kit which I've forked out a fair few quid on

More fiddling today. Won't be able to get a full 8 hours of Prime95 in but it's all looking hunky dory so far; temps look good, I can live with mid 60s
Earler in this thread i posted about an I5 i OC'd to 4.2ghz.
Since then it has been working for a living crunching prime numbers.
llrnet is the software i use to do prime tests, think of it as a cousin of prime95
Temps are up a bit but ambients are a lot higher now.
I wil be letting it install some windows updates shortly and inevitably it will require a reboot, thought i'd grad a screenie to show how stable it has been.

Lol, yeah I meant 1.19v, 1.9v would burn the chip in a sec.
