I have 2x1GB G.skill Pc6400 HZ, E6400 and P5b dlx with BIOS 614 official.
At 400 FSB, RAM can go at 1000 only with 5-4-4-10@2.3v, not 4-4-4-12. If I set 333 FSB, RAM can go at 1000 with 4-4-4-12.
With this ram, I can't go over 440 FSB with ratio 1:1, I don't think that are voltage of chipset because with all voltage at defafult the mobo can go 440. If i rise voltage the situation is same.
Actually PC runs 400x7 RAM 1:1 4-4-3-6 @ 2,1 volt
There are some tweaks for this ram & P5b Dlx? WE can resume in all tweaks in this tread, if there are......
P.S. sorry for my bad english
