With a 45nm quad running at only 1.152 Vcore, core temp's (Tjunction) of > 70C and Tcase of 76C under load are way too high. You need to get yourself a better HSF.

I think this is enough for the E7500 running at 3.5GHz on Stock Cooler, though its not a big change in speed. Take a look here: http://valid.canardpc.com/show_oc.php?id=842240 Thank you guys!

50 iterations @ 10k is a good start, but I'd serious up the problem set size to 15k or 20k and do 100 or so running overnight. Again, that E5600 I was working on @ 10.0x333 using a 20k problem set overnight for 11 or 12 h. You'll notice that it takes a good 4-5 min to complete the calculation compared to 30 sec on a 10k problem set. I've read examples of people passing 100s of smaller 8k-10k sets and failing after only 15-20...

The general rule for that chipset is to stay away unless you need SLI. I didnt find it THAT bad, however there are more noteable issues with it than say the 965/X38/P35 chipsets that were around at the same time. Bump the NB up .1 and FSBt .1 and see if that helps.

Yes, some boards will allow the 21x multi (I believe the Intel like I have and one other STOCK, and some other Asus boards and possibly others have a mod'ed BIOS) and it will run full time on all 4 cores (8 threads). Technically 920 only has 20x and lower, but it seems to be more of a boards limitation, and not the CPU.

I see several folks using LinX to test for stability. I'm old school I suppose and have been using Prime since I started overclocking. Either should work fine. With your i7 920, you should be able to reach 4GHz (20x200) without any issue. I would increase the voltage to about 1.25v and work your way down from there to check for stability; or if it's all good, try for a 21x multi and see what happens. Although I would also recommend...

Okay. I got the memory timings set now as they should be with no OC on them. Things are running great, just gotta get the OC going. The only option under the Performance is Normal/Turbo, I figured Normal was standard. EDIT: Update. I can't get anything to go over stock with this board. I'm starting to think my PSU is too weak to do anything. It's 600w, but it's old, and beatup.

have you upped the Vcore yet? try upping that a a few notches. im running mine at 2.62 ghz with a vcore of 1.3v, you should be around 400FSB with a vcore of that if you have yet to change that at all.
