Just an update. Switched out the I/O board ($30 on eBay) on the DL580 that wouldn't boot with E7's and am now up and running. Using standard mem cartridges too, which is great!

I've also tested ROI coin with several memory configurations and the best hash is definitely achieved using all eight cartridges, using two 4gb mem sticks per. Haven't tried one yet, but really don't see a need to either. Setting huge_pages to 1024 is also optimal. Plus I've figured out how to achieve the same hashes with 8837's as with 4870's. A little tweaking on settings and all is well! These processors are pretty amazing.

You guys really should check out ROI coin. If you deposit coins for a one year period the returns are astronomical. It's a relatively unknown coin right now, so difficulty is very low. It also equates to the coin not being very high in value, but with the team of devs behind it and some time I'm totally confident this will change. And even if it doesn't increase in value after three years of rolling everything into deposits, which is unlikely as more people get on board, the returns are absolutely amazing!

I haven't heard of ROIcoin until you mentioned it. In fact I misinterpreted your post where you asked: "Is anybody running ROI on a DL-580 G7?". I thought you were asking about "Return on Investment" on the purchase price of the HP DL580 G7 and the cost of mining on it. That was why I was posting about reducing power these systems use when mining.

As an example I have two HP DL580 G7's each with 4x E7-8837 Xeon Processors and 8x Nvidia GTX 750 GPUs. When mining Monoreo they use 2114 watts for both or 1057 watts each. They are currently powered down as the profitability has been negative recently. Today it is a few dollars on the plus side:

2% profit and paying $112.63 for electricity and only earning $3.34 is not worth it. If Monero gets back to $130 or higher then I will turn them back on.

I do hope that your electricity cost is low as these systems do burn the power and since you are using seven more cartridges that is an additional 210 watts per system above what I am seeing.

Have you installed HP-Health on your system?

If you have then doing: sudo hpasmcli -s "show powersupply"
will show you the power used by the power supplies installed. To get the wall power take into the account the power supply efficiencies. If for example the power supplies are labeled 94% on the fan then take your measured power and divide by 0.94 to get the wall power. Example 888 watts divided by 0.94 is 945 watts.

On the subject on ROIcoin is there a market (exchange) where they can be traded to BTC?
