I have seen a bunch of post in hardware asking if this board works with no replies to them, that I have seen. I am new, 1st post, so I can not answer these guys.
Yes 8 PCIe ports populated and mining with HD 5870's.
I know it doesn't matter much for mining purposes but if you'll use the board later on for gaming or something else,
4 slots - 8x
2 slots - 4x
2 slots - 1x
No hiccups running LinuxCoin, will be trying BAMT later today. Had to install and use ATITweak instead of ATIconfig and AMDOverdriveCtrl. I don't consider this an issue though as ATITweak if far better IMO.
Only issue with having 8 PCIe ports populated with GPUs is power. I am running off a 120v outlet and the wire gets hot! If this is a rig you're going to look into, use 5830's or use a 240v outlet to power it.

I will post a screenshot up later when I get a chance for proof of operation and stability
Don't waste money on new with this board either. I purchased an open box from newegg for $279, saved a hundred bucks and it came perfect.
