[crotale]

I'm working on the vmch. I think I got it figured out, but I'll verify it first.

I'll see if I can find out vdimm too.

[Tommy L]

ja, det hadde vært fint!

Lookin forward to it! my D9 needs more volt than 2.3 and mch more than 1.45

[crotale]

Here you go!

I have tried them both myself. I take no responsibility if your board stops working, etc. Enjoy!

Just over the dimm slots


Just below the PCI-Express port


Updated with vcore mod and vcore read out:

thanks

are u using the 13 bios? and vdimm? are those ddr2 micron D9 fat?

[crotale]

Haven't had much time with the board, so I haven't tried how good it clocks memories.

I've run both BIOS 13 and a 14Beta, but I didn't notice any difference in overclocking between them.

[ReMEDy]

I use Beta Bios 'AB9-018" and This is some result I can get from this bios.No need to Vmod.

If I've more time for this board I'll post for more result.

[d@rkn1ko]

where I can take this beta bios?

[Tommy L]

would love to se that with higher multipl...

i have the 14 bios and cant change multipl (ES) and the board wont let me get moore than 401.5 even if i set it to 500.. stays at 401.5 x 9 that is.

does this ab9-18 bios fix this issue?
