Hey,

I got the P5K-E/WiFi last week and installed it. Cooling mosfets with thermalright Hr-09 type 2 (pics to follow)(hardmounted). Cooling NB/SB with thermaltake extreme spirit II heatsinks. Cooling E6600 with water. 850watt antec TPQ PSU, 2gb Pc2-6400 corsair xms2 (5-5-5-15-2T, 2.10volts)

I installed bios 0901 before finding out about the vdroop. I can not return to 0602, 0603, or anything else. I have tried EZ flash in the bios, and Asus update utility in windows Vista 32bit. Update utility says "Bios image can't use in this motherboard. The EEPROM type incompatible." EZ Falsh says the bios is older than the 0901 bios, which is obviously correct.

Can some one suggest another method of downgrading bios to 0602?

I can not understand this method.

Did vdroop mod from page 1 of this thread, brought up the droop a little. Still a large gap, almost 0.1 volts
