Well Eva trust you to show up looking for benches..LOL

Its 4.2V max at the mo but things may change..we will see.

Results for me were i was able to hit 262fsb EB@2.5-2-2-5 on the P4C800E where i got 3-2-2-5 at 256 with 2.85V..so i maxed my dimms here.
I had OVER ddr600 with 4400beta at 3.4V and my BH5 gained 6fsb over their last max on unmodded boards.

I must stress my unit is Alpha and has no filtering on board so the new units will be a little better..i can and will mod my unit to full shipping specs so there will be more results soon.

The unit does take one dimm slot..the ram plugs in the board as normal as if it didn't trace lengths would be a mile out and no voltage would help the dimm clock.

The shipping units will be available for A64 boards also with the pot vertical etc so you should still be able to run 2 dimms.
