So I have an R710 with twin quad 2.8 proc, four 1TB SATA drives and twin "eco" PSU both powered. According to a KillaWat, a single PSU is pulling about 150w, when both are online, each is pulling about half that at 75W.
The RAM config was 12x4GB total of 48GB. I bought 6x4GB additional to populate the empty slots aiming to go 18x4GB = 72 total.
However, after installing the RAM, the server locks into a reboot cycle claiming a W1628 error that there isn't enough watts. Nothing else changed. I can't fathom 48GB drawing another 850W (assuming the power supplies operate accumulate as 2x500W) or another 350W if the "max" is only one PSU. Should I really be needing the 870W PSU when I haven't added anything heavier like more drives ?
According to DRAC, the PSU firmware is 08.04.00 and everything else appears to check out.
Any suggestions ?
