how high have yoy had youre v core up to and how long have you ran the cip?? the 45 nm chips do not need alot of voltage!!! was the chip ever stable if so how long did you test it for!!! let me know ok i may be able to help ya out, since i am running the qx9650 and have been up to 4.2 on air stable quad prime, v core still low...wolf

I have tried all possible vcore voltages against all possible NB voltages. GTL and TERM to not have any effect. The only OC I am able to achieve is the 3.54Ghz using the settings: vcore +0.175v and NB 1.375v all the rest auto. Thats FSB at 1574 and ram at 787. Timings of ram at SPD. Ram voltage at 2.10v. Bios 1B4. It's weird because 1600/800 will not post period regardless of voltage settings, but 1750+ will post sometimes but BSOD at windows. I have also tried relaxing ram timings.

This is an off topic question but I feel I must ask. When running Prime95 at stock settings, only 1 of my two cores is utilized. Core 1 is only ever maxed at 85% and core 2 never surpasses 20%. I have priority set to 10. I have also tried H.264 video encoding with a program called Handbrake which supports multi threading and I see here also that core #2 is hardly used. Does this mean anything? Are there tests I can run that will max out both core to prove that my #2 core is working ok?

Finally there is a section in Prime95 that suggests running 1 instance on one core and other instance on others. When I try lo load multiple instances of this program the first loads and stays loaded but subsequent instances just shutdown immediately. Is this normal?

Update: I have since replaced Prime95 with SP2004 so i can get multiple instances. Both cores max out with two running. I have also aquired Everest Ultimate and i ran the cache and memory test. Compared to other results i've seen I think my results are alarming. See here:
