i7 920 D0 @ 216x21 = 4536mhz
HT on, EIST on, VM on, everything but C1 on basically.

mobo is a x58a-ud7 with EK FC block in the cpu water loop on bios F6
Running around 1.4v cpu on bios but it's about 1.36v in cpuz.

Watercooled setup:

apogee gtz
Indigo Xtreme
2x mcr320 with 9 gentle typhoon 1850rpm (3 on 1, 6 in push/pull on 2nd).
1x mcp655 + EK custom top
distilled water

Max temps are about 73c on 1st core.

There's also a similar loop on the 5970 (ek fc block, both rads are only 3 fans each, same pump/top combo).



I'm considering pushing to 21x220 and see if I can do it with less than 1.4v... I'll keep you guys up-to-date
