Power and internet have been out for the last few days, so I am just catching up. Did you already grab this board? I like the board and haven't had any issues with it. You might have to disable some onboard peripherals to get the board to recognize GPUs in all the slots. I have an X399 Taichi, but it is missing the VRM heatsink. I pulled the VRM heatsink to run a waterblock on it, and somehow managed to knock it off my workbench, and then step on it, which pinched the heatpipe. I tried to get a replacement from ASRock, but no luck with that.

Folding on the CPU, even with a slight overclock, on air, is going to be a tall order unless you have a pretty good cooler. Pretty much all of the new CPU tasks are primarily using AVX instructions, and you are likely to see temps and wattage roughly in the neighborhood of Prime95 "blend" or even a bit higher.

The limit on PMs is a real joy. It's been a bit since I sent out a bunch of PMs on OCN, but I I think I can PM 25 users at once. What I did was split up my list into chunks in a text file, and then just copy/paste the broken up list into however many PMs I need to send. I don't remember hitting a hard limit, but it has been 8 months since I did that so not sure on any changes that might have happened since then.

Nice. I have a few of those and a passive x8x8, and they work great. For Threadripper on X399, I can say that 6 GPUs definitely work. The max at 7 I think would only apply for x8 slots, but I can't say for sure since I've never exceeded that number of devices. As long as you can bifurcate a x16 slot to x4x4x4x4 I don't see any reason why you couldn't add more GPUs. You may have to disable some USB and/or sound devices, depending on how your board handles addressing devices, but other than that, there is no maximum device limit on X399 and Threadripper.

Thanks for sending it up the chain E. ? I just set custom rules for my inbox, and then clean them out periodically. I will say that the "security" concern is an interesting take on user security. I guess it's nice to know when you've been pwned, but by the time you see the alert, the damage has likely been done. 2FA and/or hardware tokens are really the best, easy to implement solution. In my experience, most user facing security items that are likely to cause user fatigue, are not worth the time to implement. If something hits a user's inbox multiple times per day, then the natural thing to do is to ignore the alerts, rendering them useless. This is similar to password fatigue, where you require the user to change their passwords frequently, which annoys the users, and then you start to see things like oldpassword1, oldpassword2, etc, or just shorter and easier to remember (i.e. insecure) passwords. FWIW Google, Microsoft, and a bunch of other large corps do the same thing with logins.

The Splitty 9 Active is a nice little powered splitter if you are just looking to power some fans, and control them via the PWM header on the motherboard. https://modmymods.com/aquacomputer-splitty9-active-splitter-53231.html

I like it. I have a few very similar benches w/o the acrylic. I just spaced the crossbars to match the standard ATX dimensions. The "i need to be able to stuff more GPUs in this rig extended height edition"

I'm all about competition. Once upon a time I had a TC 290 OC'd to the moon, and it was beating 290X's, 390X's, and maybe even a Fury or two. I'll be around to lend a hand with anything you guys need, and I'll start brainstorming on some ideas for the reincarnation of the TC.

Someone had floated the idea (over on OCN, was that you @BWG) of pooling all the interested folders, and then doing a draft to fill out the teams. I think that is a decent idea, because it might even things out a bit. I know that I was generally able to recruit people for my team, but that wasn't always the case with other teams, and I had an advantage since I was the Editor of the BOINC section. Outside of having enough folders interested in joining, the most important thing will be to have a reliable stats site. Not sure how specifically you want to structure the teams, but we could look at CPU, GPU-O (open), NVIDIA, and AMD. Balance is always tough unless there is a full roster for every team.

I'll be leaving a 2080S and a 5700XT up and folding for a bit. ?

It's not terrible, and I can actually power limit the cards to about 225W without much of a loss in production. Most WUs are right around 1.6M ppd.

I tested 1x on a 1070 about a year ago, and the average was about -25-30%. With QRB it scales a little funny. The higher ppd WUs actually take a bigger hit because of how QRB works with more bonus points the faster the work is completed.

They are not great for folding, but I am currently folding on 4 Radeon VIIs. Currently the best WUs are only about 2 million ppd. There has been a steady decline in AMD folding ppd for the last year across all AMD GPUs. There was a time when AMD GPUs were starting to catch up to their NVIDIA counterparts, but that shipped has sailed with the CUDA WUs. I haven't specifically look at the latest cores, but I am somewhat sure that the hot-paths are seeing mostly CUDA optimizations. Once upon a time there were WUs that were 4M+ ppd, but that hasn't been the case for at least the last year.

Pretty close to listing a handful of Radeon VIIs on Ebay. I bought all of them brand new for $550, except for 1 that I bought at launch for $700. Currently they are selling for $1500-$2100. Selling them now would allow to grab a pair of Radeon Pro VIIs that are actually more useful for me with the Infinty Fabric link and full fp64. ? *Edit* On top of the low price that I paid for the cards, I am basically even on the purchase already, since I have mined eth with the cards from time to time when they were idle.

Didn't notice that you were on Windows, so not sure how that all works. I know that CUDA is bundled with the GeForce/RTX drivers, but I'm not positive if that's the case with the Tesla drivers. Are these the drivers you installed? https://www.nvidia.com/Download/driverResults.aspx/170719/en-us

No reason to run an ancient version of CUDA, and I believe that you will need at least CUDA version 9 to run the F@H CUDA WUs. After you install the latest drivers I would delete the cores in your F@H data folder, and then start the client. The client will automatically download new cores at start up.

The major uptick in ppd for NVIDIA GPUs is from the new Core_22 WUs which are running on CUDA rather than OpenCL. Performance boost across the board is 25% or so, with some WUs doing even better than that.

Ha. That's what I do, and everyone I know thinks I'm nuts. My music library has doubled in size over the last few years with everyone jumping on streaming. You can grab boxes of CDs for a few bucks at most pawn shops.

Right on. If I had gone X299 instead of Threadripper that's the board I would be running.

AAC @ 256kbps.

Not too bad, but the ppd/Watt number is not so great. 300W+ to get that 1M ppd running at 4.2GHz.

Missed this over the weekend. If it's not too late, and you are interested in something like an X99-WS or an X399 Taichi, let me know. I also have a spare Xeon that can go with the X99 board. I'm across the pond, but if time isn't an issue...

Should have a few more GPUs to throw at this when I get home tonight. On the CPU front my 3960X folding on 40 threads is at about 1M ppd. ?
