40 5830s? IN how many rigs?
20 rigs. I averaged about $0.71c/per million hash on the builds.
Wow... why only 2 cards per rig isn't that a bit inefficient? having to have 20 mobos and cpus and psus instead of 3 or 4 cards per rig?
limits downtime/outages? Would you want 3-4 GPUs offline or 2 at a time? but, perhaps the owner can share their reason with us?
This is EXACTLY the reason. Not to mention its WAY easier to cool them. I'm up to 70 5830's as of today. When a box goes down it doesn't effect my production that much. Plus I don't like pulling GINORMOUS amounts of wattage on single circuits. This just works way better for me all the way around.
Here's a picture of another stack I just finished today.
