Title: PCIE expansion board
Post by: wowc8 on May 16, 2013, 10:02:57 PM
Curious if anyone has tried anything like this:

http://www.cyclone.com/products/expansion_backplanes/pcie2-460.php (http://www.cyclone.com/products/expansion_backplanes/pcie2-460.php)  

Looks like it would allow for using only one mb, processor, and set of dimms for a giant mining rig.

Any idea what the issues might be if you ran one of these with all x16 slots used by gpus?

I have found that over-the-counter consumer hardware is still cheaper.  I encourage you to contact them, however.

Yes. For instance I see no power supply at the slots, so unless you are going to use powered risers you'll fry the hell out of your motherboard.

I totally agree, but if I was going to run more than three cards I would need to use powered riser cables anyway.

Would the motherboard be able to support something like this?  Anyone try adding more pcie slots to there rigs?

Is this their store?

www.buycyclonemicro.com

Not sure, but I was just using that link as an example of one option.  Paying 1k for a single board would be cost prohibitive, but I've seen boards on ebay go for under 100.
