tictoc

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. ?

This ^^ Unpopular opinion incoming. ? One of the reasons why something like Ethereum was designed to be asic resistant was so that the distribution of eth would be very wide and not consolidated with just a few people holding all the coin. This implementation appears to only target the Ethereum algorithm, so other coins could still be mined. The real question is what NVIDIA does moving forward. Locking hardware functions behind a closed driver, and or bios, for market segmentation never benefits the consumer, and is only done to increase the bottom line for the company. This is nothing new for NVIDIA, since they've been doing this to professional users with their Quadro GPUs and drivers for years. Same silicon, but 10x worse performance for many professional applications without a Quadro and the secret sauce in the drivers. What's next throttling all CUDA, OpenCL, and ML functions, so that exactly zero GPGPU can be done on RTX cards?

Probably too late, but the ASRock X399 Taichi is a great option for multiple GPUs with bifurcation support. I ran 5x GPUs in mine with no issues. Not sure if the latest BIOS has x8x8 bifurcation for all slots, but ASRock support sent me a BIOS with x8x8, x4x4x8, and x4x4x4x4 on all the slots. I would definitely recommend a board that has auxiliary power for the PCIe slots if you plan on running more than 3 GPUs 24/7. Otherwise you have a chance of burning up the 24 pin connector on the motherboard (at best or a toasted board at worst) if you are pulling full board power on your GPUs. I've had great luck with these risers https://peine-braun.net/shop/index.php?route=common/home, since he first went into full production over on [H].

Here is the link to the Phoronix article where the info came from. https://www.phoronix.com/scan.php?page=news_item&px=AMD-Sched-Invariance-Fix-Merged and some benchmarks: https://www.phoronix.com/scan.php?page=article&item=linux511-regress-over&num=1 It should be noted that many users would not have been affected by the performance regression. I have always just used the performance governor on my AMD machines. The schedutil governor has pretty much been a hot mess since it was added to the kernel. The ondemand and performance governors still outperform schedutil. There are also still bugs with scedutil and Zen 3 CPUs that probably won't land in the kernel for a few more weeks.

That script basically matches my burn-in procedure for new HDD's, except that I usually do short S.M.A.R.T.->extended S.M.A.R.T.->bad blocks->extended S.M.A.R.T.

I think you are thinking of 10 or 10/100 Mbps ethernet, and yes that is slow, but 10 Mbps was blazing fast in 1982. ? Once you get up to high enough speeds the copper itself does become a limiting factor, but for consumer gear, looking at the slow adoption of 10 Gbps, that is probably a decade away. There are very few switches on the market for consumers (at a reasonable price) that can do 10 Gbps with standard RJ45 copper connectors. Anything with more than one or two 10G RJ45 ports is going to be $300+ dollars.

I have a 10 Gbps copper switch and it has no issues running at full rated speed on CAT 6A. Longest run is about 30 meters, but 6A should be good out to 100 meters.

^^This. Distilled plus a few drops of Mayhems Biocide+ and Inhibitor+, keeps all of my machines running nice and clean. A 15 mL bottle of each is enough to treat like 30L of distilled, so basically a lifetime of fluid if you only have one system. ?
