4 cards on an AsRock Z68 Extreme4? Advice needed

[simonk83]

Does anyone here use an AsRock Z68 Extreme4 motherboard?

It has 3 PCI-E 16 slots, which is fine for 3 cards, but I'm just wanting to check if you can fill those and also use a PCI-E x1 riser and it'll all work fine? I've been reading about and some motherboards seem to disable slots if you populate the x1 slot.

I'll have a 1200W PSU so I assume Power will be fine (touch wood), I just want to check that I can get 4 cards running

Thanks all!

Anyone?

I don't own it, but the manual doesn't seem to indicate any disabling of slots with the 1x slot occupied.  The only notes they give indicate that using all three PCIe 16x slots will restrict bandwidth to 8x/8x/4x for those slots.

I have this MB and have 4x 6950's with 1 connected to the 1x via a riser.

How did you fit a third card in the bottom pcie 16x slot?    I have two (now three) 5870's which are dual slot cards.    I just installed the new psu and was about to install the third card but it doesn't look like there's any way it'll fit...

EDIT:  Just opened it again, no chance at all.   I assume you guys are running caseless?
