^Drop the RAM multiplier all the way and then start upping the BCLK. Don't worry about the stock cooler. If he has decent case airflow then it'll work well enough for a reasonable OC. These chips don't make much heat.

My temperature according to Real Temp didn't go above 69 degrees with the CPU running at just over 50%.
I'm doing a quick 15 minute run of OCCT and so far, so good. Same temperatures but this time with the CPU being fully loaded.
When I have time I'll either do an 8 hour run of Prime95/Orthos or a full 1 hour run of OCCT. If there are no problems after that I'll start to dial in my voltages and memory timings.
I can tell you with 99.9% certainty that that setup isn't going to be 100% long term. 1.10v IS default VTT/IMC and with QPI at 8000 I'm amazed you were even able to boot into Windows with that voltage.
When testing for possible IMC issues, you need to test for a long, long time. 12 hours of Prime or 6 hour of Linx minimum. They seem to be more time dependant than stress dependant.
From what we've all experienced throughout this thread, I'd say you'll probably need a bare minimum of 1.25v and probably more like 1.30v for that QPI.Edited by AyeYo - 4/25/10 at 6:28am
