Here is a weird one for you - I got a combo for my brother for x-mas (2400+ and deluxe) I can run it all day @150 fsb 1.80 volts (runs cool too with Dr. Thermal but a bit loud of a fan) - So I read the 1001.e bios gives you the unlock feature of the other nforce2 boards (came with 1001.g bios - only higher mulitpliers and no changey - only fsb upping)...so I flashed it to 1001.e and I got all lower multipliers and I thought WHoOOOO - sure enough I can select 10, 11, 12, but nada it still stays locked at 15 (even though it says 10 in the bios) - So I figure I will flash it back to 1001.g since there is no reason not to and -- the lower multipliers, they are still there!!
Buttt--still no luck other than the fsb (I can get to 2.26 no problems stabile till the cows come home) but would like to hit the higher fsb speeds for the mem throughput...
