HPE DL380 Gen10 w/ 6132 Gold idle power consumption too high!? (alien.top)

Hi there,

I am just surprised this machine I got from a refurbished sale has quite high power draw. Even when I remove all of the peripheral parts and just leave one CPU in the chassis, so remaining just:

- 1x Xeon Gold 6132 (14c/2.6 GHz, 140W TDP), 2x 32 GB RAM 2400 MHz

Even then, idling (no OS, just in UEFI mgmt.), the machine draws at least 112 Watts from the socket from which 64W go to the processor and 6 to the RAM (says iLo). The remaining 40 or so Watts are lost in the system.

When I install the 2nd CPU the CPU draw rises to ca. 120W, so I already got a good saving here.

Nevertheless I find this a bit too much, also considering some other testing labs results which seem to be significantly lower. For ex. see here, which supposedly not only shows CPU but the whole system consumption.

Do you have any explanation for this?

Thanks and cheers

My brother in christ why didn't you run an OS to make sure the acpi can be controller properly?...

Well, now I did .. after Proxmox install, we're heading the right direction: 1 CPU installed, 2x32GB RAM (as above) plus Raid controller P408i, 8x SAS backplane and 2x 10Gb Eth. NIC it idles at 74W out of which 15W go to the CPU. With 2 CPUs we get 87W in total with 19W on the CPU.

That's a completely different story. Was not aware of this ..
