Can you fit another PCI-E card in there though? I ask as thats what I want, I have an X1900XTX and an ARECA 1210 at the moment and want to add a second X1900 for Crossfire....

Looking at the pictures of the board and the size of the X1900s, I can't see how you can fit 2 x GFX + RAID, unless you fit the RAID in the blue slot and the gfx cards in the black slots....my understanding is that that gfx cards should be inserted into the blue and white slots though (they are the only 16x wired slots)?

Board is wired 16/0/4/0 or 8/8/4/8 top to bottom - blue/black/white/black.

Unless I'm mistaken there are no boards that run dual 16x when both slots are occupied, it just means both slots are capable of it. So the P5W-DH will run 8x/8x when in Crossfire, and so will this board.

It has been confirmed elsewhere that Crossfire can be done on 1+4 or 2+4. If you used an X1900 card in the blue slot (1) and another in the bottom black slot (4) you'd have space to fit the Areca card or any other PCI-e card in the white slot. It would only run at 4x though, but reviews seem to show it doesn't make a huge difference running at 4x or 8x.

Hope this helps :)

Many thanks, thats just the info I was looking for :)

I have been testing a P5WDG2 WS Pro, and if I set it to anything higher than 1.50 or 1.55 (can't remember which), CPU-Z reports the voltage as 1.2x volts!!!
I just assumed this was an error in CPU-Z, because I am quite sure that the ASUS utility reported it as being close to accurate. Could this be true, or is it just a software bug?

Albeit, that's using hardware monitor to measure not a DMM, but i think it's close to reality because I could get the same overclocks at 1.6v BIOS (1.64v reading - overvolt) as I could at 1.7v BIOS (1.64v reading - undervolt)

What really sucks is it only allows 1.7vCore and 2.4vdimm :(

This isn't limited to Asus mobos. This happens on pretty much all C2D capable boards available at the mo :)

Is the reason for this known?
(sorry if o/t)

It's just a CPU-Z error, I don't know why but I don't think it's a big issue. I use BIOS hardware monitor or the Ai Booster readout (they match). Anyone with a DMM have any actual readings?

From memory, the manual on the P5WDG2 WS Pro states that the second PCI-Ex slot runs at 8x only, whether you have a card in the first slot or not. In SLI/CF both run at 8x.
Unsure whether it's the same with the P5W64 Pro though.

Also, I think there were some AMD boards that ran dual 16x in SLI but with no major performance gain.
