Allways check Pci-E lane distribution before purchase if expecting to use all ports on a mainstream board !
On mainstream boards they allmost allways will be shared somehow, and most company´s list how this sharing is done in the specification page.
Lane sharing varies much on mainstream board so newer is not "better" as so.
You migth want to consider LGA2011 witch has plenty of lanes to spare comparing to LGA1155
Okay, well i am using all 3 GPU slots, but i can see that i need to unplug my 3rd GPU in order to use my 3x x1 pcie slots, limiting me to 5 gpus..
Thats a bit of bummer, since i use to run 6 cards on an old cheap H61 board.. Did not think a newer board would have such limits.
If i plug a x1 pcie into the 4x pcie will then be able to use the all 3 pcie 1x slots?
I can say that after i Disabled the pci x4 it would see the 4th GPU, but with that said, its not playing nice. It still wants to use the 4x as primary GPU which annoys me a bit.
I cant get the rig to behave as i want, if i removed the 3rd card, nothing puts out an output, and that makes it very hard to know what the heck is going on??
I found that by running on the 3x PCI-e slots and the 8x 16x slot, i could run with 4 cards.
So as far as im concernd there is no more problems.
I'll just want to bring the last update on this subject.
The card was returned to the shop, and they were fast to test it and called me up, they got the motherboard running with an nVidia card, after a full bios reset, which is also had done a few times.
Since I bought a new motherboard in the mean time, they asked if i wanted my money back, as they saw no damage what so after on the motherboard, and i agreed.
So for now, i no long own this motherboard, but i do have one question. I had asked for the 4 year warranty, and i got my certificate yesterday. If this board is to be resold, I dont want this to have an impact for a potential new owner, so please tell me if i need to do anything about that.
