Linux used to have a larger lead over Windows when it came to Folding but changes in Core 21 changed all that and dramatically reduced the difference. Now there is still a performance bump with Linux over Windows but it it is typically only about an advantage of 5% or less depending on the Work Unit (WU). Mostly down to Linux having better (more efficient) mechanisms for PCIe Bus arbitration. Under the hood Folding uses OpenMM for modeling Protein Folding. On GPUs both OpenCL and CUDA are supported for OpenMM. AMD supports only OpenCL whereas NVidia supports CUDA and OpenCL. CUDA always enjoyed a 10-15% performance increase over OpenCL for Folding but during the Pandemic the CUDA Libraries were optimized further by NVidia and now CUDA out-performs OpenCL significantly. The net result is, though on paper the Dual-Precision Floating Point (FP32) throughput of a GPU (TFLOPs) should be a good indicator of the yield of a GPU while Folding, in practice NVidia GPUs are almost double the yield of a AMD GPU with comparable Dual-Precision throughput. So while AMD GPUs may be the value king for rasterization in Gaming, Nvidia GPUs end up being a better value for Folding despite their expense. AMD could likely improve the Folding Performance of their GPUs by implementing ROCm on their Consumer hardware but, for some reason they have decided to only support ROCm on their Enterprise "accelerators"

LOL - This seemed appropriate for the Data Collection Staff

@GOTSpectrum "... vsteel is continuing to man the post of the Honourable Gatekeeper, taking up 19th ..." Don't you mean "10th"?

More so down to the Silicon Lottery. There are likely no changes in the Intel Memory Controller on the 14th Gen "Refresh." Some chips will have better Memory Controllers than others. Intel's Specification for 14th Gen for the rated maximum RAM speed is 5600MTS which is identical to 13th Gen. YMMV

I have the Intel version of that board and the VRM is weak but even then a 5950x is very power efficient and the VRM should be OK. x570 boards are starting to get scarce. Yes, I rolled that LOL - @leadeater passing others with just CPU Folding? If you get a Cyber Power or APC unit and use the HID Driver rather than the manufacturer's software it will actually issue the "On Battery" Flag and pause Folding on the system (see the UPS link in my Sig.

I'm surprised it's yellowed that quickly as that case (Lian-Li O11 Dynamic Air Mini) has only been out for a couple of years. I would be hesitant using Bleach or Hydrogen Peroxide on the case without first testing on a small portion to verify it won't attach the finish. Say the 2-slot PCIe Expansion Card retainer at the back). As for using it for a NAS Build ... it only supports 4 x 3.5" HDDs and mounting two on the side bracket is tricky:

Nice, but you'll excuse me if I defer changing over to beta software this month.

@Windows7ge The v7 Debian build, however, still has a bug that makes the service FAHClient stop not work. You need to patch it to get it to work properly: Patchfile for /etc/init.d/FAHClient: --- FAHClient.orig 2020-04-15 01:53:38.000000000 -0400 +++ FAHClient 2022-04-30 17:35:21.434251186 -0400 @@ -121,6 +121,7 @@ fi pid=$! + echo $pid > $PID if wait_for_log_change "$LOG_STATUS" $pid; then echo "OK" else

No, I've slowed down somewhat today as the weekend is over and Electricity is expensive most of the day again. I suspect you'll be pulling ahead of me weekdays and I'll do a bit of catching up on weekends.

or procure some Loctite Threadlocker 242 Blue.

No, I'm happy where I am but Lucky #7 would be nice but I don't want to force @Alex Atkin UK to have an even more expensive electricity bill. Still, not too shabby for 1.4kW 50-75% of the day

Here's the efficiencies I'm seeing: Top 4: 4070ti; Orange: 4070, Yellow: 3080; Purple: 4060ti It appears the chips used on 4070tis are binned better as my 4070 and 4060ti get much lower efficiency in practice then they should just based on CUDA Cores and FP32 Performance but even those are almost twice as efficient as the 3080.

I bough a boatload of 3000-series B-stock EVGA Cards when they were still on Fire Sales at their web site and though I love EVGA Build Quality I quickly regretted this as the 4000-series, if run at the sweet spot (2200-2500MHz) are almost twice as efficient as 3000-series (1440MHz). For gaming they don't make fiscal sense but for folding, if you care about your power bill they are the best. I have 4 Zotac Trinity OC 4070tis in 2 rigs so 1/2 slot of space between the lower and upper cards. IF you run them clock or power limited they're fine with that little space (48-53C on lower and 66-70C on the upper) but I am considering removing the backplate on the lower cards to get more room to breathe. And, combined, you can feed these two cards from 3 dual 8-ping PCIe PEG Power Cables if your running them with a clock or power-limit (likely a bad idea if you want to run them full-bore). The easiest way I've found on Linux to automatically apply the limits is via a shell script run at reboot from the root crontab: cat /root/setpwr.sh #!/bin/bash nvidia-smi -pm 1 nvidia-smi -i 0 -pl 175 nvidia-smi -i 0 -lgc 0,2205 nvidia-smi -i 1 -pl 175 nvidia-smi -i 1 -lgc 0,2205 crontab -l # use /bin/bash to run commands, instead of the default /bin/sh SHELL=/bin/bash @reboot /root/setpwr.sh > /dev/null 2>&1

I haven't had the opportunity to test a 4090 but from the number of CUDA Cores and the theoretical FP32 performance, assuming both that it scales linearly (it does) and you can keep it fed with big WUS, it will be the most efficient. The issues are that your don't always get big enough WUs and without risers you can't get more than one in a normal ATX case and to support more than 1 GPU and then you also are getting past the 850-1000W "sweet spot" for power supplies and into the realm of much more expensive 1200-1600W units that have enough PCIe PEG Power Connectors. The 4080 should be a better value than the 4070ti but it's price point is (still) too high so the 4070ti tends to be at the price and efficiency "sweet-spots" but the 4070 might be better for dual rigs as this is the first model with 2 slot cards available (excluding that Inno3D 4070ti model that is dear in North America and someone (cough @GOTSpectrum @Alex Atkin UK @RollinLower) seem to have bought all the European stock of.)

Yup, woke up to another rig with both slots set at "Failed" and stuck there for the last 6 hours. What I noticed last night was the Rigs that failed then were all running driver 535.129.03 whereas the Rigs that were still up were on 535.113.01 or 525.125.06 and one Rig on 535.129.03. Guess What? The Rig that didn't fail yesterday evening that has 535.129.03 was the one that failed overnight. So all my Rigs running 535.129.03 have all failed within 12 hours of each other. All started working again after just a reboot with no "apt update" required. I'm going to keep running as is and see what happens but it looks like 535.129.03 might have issues.

You could always create a RAM Disk and move the work directory (/var/lib/fahclient/work) to that - just to what, if any, difference that might make

Burn-In Test! Way better than mprime

If you have SSH or can run sshd on an alternate port you can port-forward a browser session from a remote machine and run the extension on that

I might slip a bit as, of course, I had a dinner meeting this evening and wasn't able to baby sit the Rigs and watch as they started up again at 19:00 EST when the Electricity prices dropped and, wouldn't you know it, I came home to find 3 Rigs with 4 GPUs (all my 3000-series, except for one 3080) stuck at "Failed" which requires a reboot to get rid of. Back up and running again but as it's now the weekend and Electricity rates are at the most affordable all weekend I should be able to make up for lost time.
