Congrats! Very nice

I went up to 2.35V on water, but FSB didn't go up. Had no time to get LN2 this week.

Thanks :-) And the funny thing is, that there was something wrong with the VDIMM mod. Over 3.2V MB didn't boot :/ We had to resign from Winbond BH-5. But Samsung TCCD on 2.8V did the job pretty well :-)

On this board vtt (v-ref for nb-mem signals) depends on memory voltage. On my one the best settings are 3,15v v-mem and 1,95 v-nb.
I'm waiting for new cpu from my friend but i'm afraid that it's to late

You probably missed the Vtt/Vref mod and the result was that Vtt didn't follow VDIMM/2 ratio. At 3.2V on the ram it had been stuck @ 1.45V.

I have this mod and I know that there has to be VDIMM/2 ratio. Board just didn't cooperate over 3.2V :/ I have no clue why. Will investigate soon.

I dont really consider it as a disadvantage. vtt/v-mem dependance helped me to reach 282mhz
