Great discussions and info in this thread!
Just wanted to share my DL580 G7 build, wanted to run 11 cards, but settled with 9 after hours and hours of struggle.
Mining etherium at ~ 255MH/s. Ran Cryptonight at 1650H/s with 4x E7-8837, but stopped since i switch to SimpleMiner from hiveOS (had to prioritize gpu stability).
So 4X E7-8837 at 130 watts each is around 520 watts, correct? Maybe not too much to worry about if electricity is cheap or free but I just wonder if there are still better price-to-hashrate-to-power options. I mean $20 for the 8837 is really awesome but then there are strong processors at 65 Watts instead of 130 Watts that are more expensive but might pay for themselves in power costs over the course of a year.
I've been trying to decide on a configuration for my next mining build that would include stronger CPU hash capability.
Thank you for your contributions here. I really enjoy this thread.
