| | As I type this I'm running prime95 in the background (to make sure), but I believe I have a stable overclock at 3.33 Ghz (166 Mhz bclock) on my new Core i7 920. I started at 150 and noticed that at stock voltage, only 2 of the 3 RAM modules were registering on boot, so I increased the DRAM voltage by .05 volts. That setting got me to 166 just fine. I attempted 183Mhz with a DRAM voltage increase of .1 volts and a processor bump of .1 volts as well, but prime95 blue screened the system within 30 seconds. I may try again, but if the 3.33 Ghz is stable with a .05 RAM overvolt, I'm very tempted to keep it set there or maybe try for just a little higher ... 3.4 or 3.5 Ghz. The processor is a C0/C1 stepping according to CPU-Z. You may have better luck with the new D0 - from what I read, the engineering samples from the new stepping are power misers & better overclockers.
Time will tell - I plan to run the 64 bit prime95 all night. I ended up ordering a copy of 64bit Vista Ultimate from the Egg when I found that the copy of Windows 7 Beta I obtained was a very early non-functional beta. I've got the best of both worlds though - I re-configured my old array into a second bootable drive and installed XP to one drive-size partition. With 1.1 Tb between the two drives and knowing myself - I highly doubt I'll be wanting for more space anytime soon. There's even room enough that I might try to split the old drive and do a linux partition. We'll see.
