Other news
I assembled the 4th Ryzen 3600 (aka GPU compute node v3) machine and have had it running in. I also have it on a power point power meter to see how much juice they use. At peak load with the  CPU and GPU fully utilised it jumped to 240 watts (at a supposed 240 volts - according to the meter its getting 236 volts). Running Milkyway work on the GPU is less taxing and it barely gets to 200 watts. Running just the CPU at full load its using 140 watts. Idle was 60 watts.

It was a bit warmer yesterday afternoon so I had to stop GPU crunching, hence running Einstein gravity wave work on the CPU only. The Ryzen 3600 is faster than my i7-8700 machines doing the same work. Both CPU's have the same core count but the Intel has a lower clock speed (3.2GHz base) and doesn't support memory faster than 2666MHz.

GPU compute nodes
Version 2 of the GPU compute nodes was a Ryzen 1700 with a GTX 1660 Ti (they originally had GTX 1060's but I upgraded them to the 1660 Ti when they came out). Version 3 is a Ryzen 3600 with the same GTX 1660 Ti.

I got another two GTX 1660 Ti's and have assembled another of the v3 GPU compute nodes. I also decommissioned another v2 as well as an i3-6100t that was acting as a GPU compute node (with a GTX 1060). I still have one more v3 to assemble and one more Ryzen 1700 to decommission. I will be selling off the older compute nodes.

The first v3 GPU compute node that I built has managed to get its recent average up to 73,400 so far for Seti. They take a bit over a month to reach their highest average and this one has been going just shy of one month. The second v3 GPU compute node that I built has got up to a recent average of 53,300 and its only been running for two weeks.

With just three GPU compute nodes running I've climbed to 61st place on the Seti rankings. I don't expect it to last too long though as once the first v3 GPU compute node is a month old I will get it doing some Einstein CPU work.
