Another one bites the dust

Farm status
Intel GPUs
All off

Nvidia GPUs
Three running Seti work

Raspberry Pis
All running Einstein BRP4 work

GPU compute nodes
The 3 new GPU compute nodes arrived as parts. I have assembled one, which has replaced another of the Ryzen 1700 GPU compute nodes. That is two done - the ones with GTX 1660 Tis. I will work on the other two during the week. I also need to buy a couple more GTX 1660 Ti graphics cards for these last two.

I have Dariks Boot and Nuke running on one of the former GPU compute nodes at the moment erasing the hard disk. Its only been going for 16 hours so far with an estimate of another 6 hours. I then have to repeat the process on the other node before selling them.

The former GPU compute nodes got their RAC (Recent Average Credit) up to 75,600 for Seti so the new ones need to beat that, despite the fact they have less cores. The first one I replaced is currently up to 58,600 and still climbing.

The old and the new
The "old" GPU compute nodes (v2) consisted of an ASUS X370-Pro motherboard, Ryzen 1700 CPU, 32GB of memory, 2TB HDD, GTX 1060 3GB graphics and a 750 watt bronze rated power supply. These pull 235 watts at the wall socket (240 volts) under load.

The new GPU compute nodes (v3) consist of an ASUS X570-P motherboard, Ryzen 3600 CPU, 16GB of memory, 1TB NVMe SSD, GTX 1660 Ti graphics and a 550 watt gold rated power supply.

I need to plug in the power meter to get an idea of how much electricity the new ones use. In theory they should be about the same as the old GPU compute nodes but as you can see there are a few differences between them.
