Is anybody running ROI on a DL-580 G7? I have three, two with E7-4870's and one with X7560's. The E7 boxes are up and running Hodlminer v1.4.1 with no issues, but I can't get the X7560 box to configure properly. Something to due with the CPU's, but not sure what. Get an aeskeygenassist error on making the miner. Running Ubunto 18.04. Thought maybe one of you guys might have a solution.

The X7560 lacks the AES instruction and because of that it is very poor for mining and probably the reason for the aeskeygenassist error.

The E7-4870 does have the AES instruction but it is not the optimal processor for mining on the DL580 G7. The best is the E7-8837.

The 10-core processors are worse hashing even if they have two more cores because the processor clock is much lower. The E7-8837 runs at 2.8 GHz on all 8-cores whereas the E7-4870 only runs at 2.53 GHz. I have verified that the E7-4870 is worse than the E7-8837 for mining.

On eBay I have been picking up sets of four E7-8837's for $40 or less.

Be sure to update the BIOS on the HP DL580 G7 before you put in E7-8837 processors. If you don't it will not even boot to the BIOS screen.
