I have an r930.
With 4x e7-8890 v4’s. 9ssd’s 2x SAS drives 4x m.2 drives on a pcie card 512gb of ram across 32 ram sticks
Pulls about 400w like all the time even at idle.
Holy cow. What's driving half of that wattage? Is it the 32 sticks of ram? Or the 4 cpu?
Your server is 75% of my entire house power, including my server.
I forgot there is also a gtx 1650 in there as well.
But honestly. I’m fairly sure the majority of the power draw is the 4 CPU’s.
96 cores and 192 threads on older architectures was a bit of a power suck. If I had it all to do over again I would for sure have gotten an epyc chip instead.
Well, a DDR4 RAM stick would use 2-4W, so 32 sticks is 64-128W alone. 4 CPUs don't help either. :)
Given it's only 512MB, it could be achieved with just 8 64GB modules, which would save a bit of power, but that's also a lot of money to put into what is after all somewhat obsolete hardware. (And I say that running a v4 Xeon as well :P)
