I haven't played a lot lately. Been crunching away though.

Actually, I haven't done a whole lot of anything lately. Aside sleeping, that is. Tonight there was a family crisis and my mum was extremely upset and now I feel like playing a game to take my mind of it, since I can't really sleep right now.

That said, all of my six CPUs have been crunching away non stop, 24/7. I passed 30 million points with World Community Grid not long ago and my PPD seems stable well over 500,000 Points Per Day. 50 cores, 100 threads will do that, I guess.

So I don't think I updated my blog with what I did regarding the World Community Grid setup. So here's the low-down.

'Cat-proofed' Crunching Zone!

In my room, I have four machines. In the picture above; the two at the rear both have Ryzen 7 2700 8-core processors, one is running at 3425 MHz on all 8 cores (locked, with tuned voltage) and the other is 3625 MHz with the same tuning, albeit with a tad more voltage for the extra 200 MHz.

Behind those, is an open-air benchtable with a Ryzen 5 2600X 6-core, running at 3750 MHz on all six cores, locked and tuned again. I wasn't quite happy with the 2700's low all-core clock speed in WCG (3.0-3.1) on both CPUs, since I'm assuming the workload is at least mildly intensive on the CPU's FPU/SIMD circuitry. That said, the 2700s ran incredibly cool and essentially sipped power, but I felt I could extract a bit more performance; hence the manual tuning. I'm of course, monitoring the systems and checking for invalid results every day. So far both have been rock solid.

Anyway, the 2600X is on the open bench, and currently hidden behind my large mirror (which is from a cupboard door) to prevent my lovely ginger boy and black and white girl from jumping up and potentially hurting themselves on the parts - and damaging them also.

Oh, and I almost forgot the machine in the foreground. That's my main PC, my workstation essentially with a Ryzen 9 3950X 16-core CPU which chugs along at stock, but with a manual PPT setting of 95W (socket power). Under a mostly MCM/MIP diet the 16 cores run about 3.65 GHz flat-out, which really underscores Zen2's incredible perf/watt.

I've also got a machine downstairs with a Ryzen 7 3700X 8-core, which is currently sat behind the TV and used as a "HTPC" or "console gaming experience" (controller + sofa). That has an RX 590 so it's pretty good at 1080p. Oh! Then mum's PC also crunches in its spare time, that's running a Ryzen 5 3400G quad-core APU, which sits at about 3.8 GHz after a while or so, though before the chip heats up and the short turbo window wears off (it'll start at about 4.15 GHz then slowly ramp down to 3.8 as it warms up).

So yeah. Lots of numbers being crunched. I also moved an AC unit (8000 BTU) into my room, because these guys and their ancillery hardware (PSUs, VRMs etc) produce a fair chunk of heat. I'll need that in the summer for sure. If I'm okay paying for the ~1600W constant power use of my entire set up with the AC, lol. Guess I'll cross that bridge when I come to it.

In the mean-time, the Science gets done and you may not make a neat gun, but it doesn't matter because it's for the good of humanity.

Check out my stats here, I'm quite proud of this so far. :3
