Awesome, thanks. I may pick one up in place of the P106 this summer if it's a stunner.

 

That's a lot more than I'm ready to spend, I think I'll grab a better PSU and hunt some B450 deals on eBay. That new R3 1300AF and 3100 both look like interesting relatively low TDP options for a good budget folding rig to keep one or two GPU's steadily fed and maybe do a little CPU work as well, or even a 1600AF maybe. I'd like to spend as little as possible, obviously, so I'll see how much I have on hand that I can recycle. I have a glut of 2GB DDR3 modules, too bad FAH doesn't like lots of RAM.

If you plan to build only folding-rig, go to second market and search for bare-bones mining rigs (without GPUs), they usually come cheap and you can put any GPU in it. Or even better, buy GPU and put it in your current PC if it has one more x16 slot.

Anything you can expand is going to be a ton cheaper than building up from nothing (see: containers vs VM vs dedicated servers). Your post reminded me about the secondhand market that I tend to forget about since I never buy used.  Due to the PCIe lane requirements for F@H (and CPU since you need 1 thread per GPU) I wouldn't give less than a 2x interface for lower end cards and a 4x for 1070/80? on up due to interface throughput bottlenecking I've seen mentioned here. Problem is most boards don't offer more than 2, maybe 3 slots larger than 2x unless you specifically select for it without M.2 PCIe adapters (which I don't know much about).

I don't know a ton about the hardware end of things, but again, that's what I've heard mentioned and regarding CPU, what I've observed personally.

I put a CloudWatch dashboard in place that shows the efficiency of my cluster. It's dropped to 52% this morning. Really seems to go up and down.

I think more people keep joining F@H which surprises me at this point. I figured most of the people who wanted to do this already were or gave up.

I'm taking my folding offline to concentrate on BOINC for the pent. BUT! I will be back!

 

Hopefully will see some more of you guys over there! Even if you just throw your CPU at the Marathon, that would be a great help!

i will be switching some but my AMD GPU will stay on F@H as Bionic don't support it very well. unless amlicable numbers or what have you is the item then i will

Honestly one of the reasons I'm taking all my cards offline is for some maintenance and what not while I can. Also need to free up the CPU cycles. Power in the new house is more expensive than the last for a reason unknown to me, but the provider can't come inspect the meter due to the whole epidemic so reduced bill for the next couple weeks will be appreciated too.

I'm almost onto the team page! Almost part of the team. Just another million or so and I'll be at the bottom!

any one else having fun with 14436 and 14443? 12hr for 133k

 

well crap i think i fugured it out my after updating the Graphics driver yesterday its now only folding on my MSI Video card and my asus is on strike....now to finish the current WUs so i can uninstall and reinstall the previous drivers and for good measure reload F@H....

 

well had to reinstall windows...and was still broken so someone posted a link to the beta in the folding forum and that fixed it.

it just dumped my 1060 and my 2060ko F@H wont even let me reengage my GPUs im not sure who did what but i think they just lost a lost of compute power

moving my mATX main system into an gently massaged ITX hs been awesome, but definitely didn't help with temps.

right now folding at a toasty 70C on my RTX 2080. seems like i need to figure out how to push some more air through this thing.

too bad this isn't my thread, otherwise i would have definitely marked it solved by now.

I bought a new CPU for that mining rig because i think the Intel® Celeron G4900 is bottlenecking my 7 GPU's of the mining rig on Folding at home, now i bought the Intel Core i5 9400F because it has 6 cores 6 threads...

If it's one GPU per core it shouldn't bottleneck anything excluding any background OS tasks. If you've got 7 GPUs on 6 cores, something's likely to have to share and it won't be happy to do so. There another PC you can put that 7th card into?

I just looked at the Task manager and the mining rig is using always 100% of the CPU, and sometimes the system freezes. So i really think it is the CPU that my GPU's are bottlenecking the heck out off.

 

And I currently have a Intel® Celeron G4900 in the mining rig that is a dual core CPU...

Well yeah, especially off a Celeron at the moment. I meant for the replacement.

No unfortunately i don't have a motherboard with at least 7 PCIE slot in to it to test. But i really think that I5 CPU what i bought will will do the trick of Tripling my PPD.

Sounds like a job for AMD Ryzen! Lots of cores for not lots of money.

Why I recommended it. A CPU and MB can cost the same as a CPU only from Intel. Probably not quite here though, but probably close.

NVidia GPUs reserve 1 thread per GPU. That thread shows 100% utilization but it's just doing a spin-wait waiting on the GPU to require more data. My 6-GPU system has a R7 2700 in it and is running 9 threads of BOINC and shows a 5-minute CPU load of 12.38 but my 2 NVidia GPU rigs that both have 13 threads of BOINC running and one shows a 5-minute load average of 15.95 and the other 14.01.

 

AMD cards are interrupt-based so you can get by with a whole lot less threads feeding multiple GPUs from what I've read. I only have the two AMD RX5700XTs so I haven't yet had a chance to investigate that further but looking at that system now with 21 threads of BOINC running it is showing a 5-minute load average of 22.19 on a 24-core processor so I likely could add another BOINC thread and still have a bit of available CPU for system overhead.

 

So you will likely still be bottle-necked with a 6c6t CPU but as you said hopefully a lot less bottle-necked.

Exactly. I made the mistake of buying an i9-9900k to get more threads on an existing z370 motherboard only to discover I needed a 280mm rad to have it run Compute with decent performance and that the VRM on the motherboard was super toasty requiring some modifications to the heatsink mount.

 

My conclusion was I would have been better off getting another 3900x and a x570 motherboard for it and it would have been the same cost as the 9900k and 280 AIO.

[Zberg]

Man these fail to send WU's are killing me.  6 very chonky boys (250-300k each) in the last 2 days sitting in a send queue, down to 10% their original value, if they every go through.

The VRM bit is why I hate the heat-slab thing MB designers have done on some boards.  You can't OC them without either a lot of directed airflow or a board surgery to put a heatsink on instead (it is otherwise a great board from what I can tell). I posted a picture a few weeks back of me stacking a sink from another board on top of a slab in a bit of silliness and it did help more than expected. Not OC good though. I think Gamers Nexus did a bit on that a good while back.

I know you've already spent the money but take a look at the build thread for the 6-GPU rig in my sig.

 

After a couple of years of folding I've come to these conclusions:

1. Two GPU rigs in a standard chassis are a bugger to manage the heat load on. If you must go this way buy a hybrid card for the upper card.
2. x299/399 just aren't worth it. The cost per slot is too high. A 6-GPU rig built in a mining chassis using a PCIe m.2 card and m.2 to PCIe3 x16 adapters is about the lowest cost-per-slot and you can run twin- or tri-axial cards more quietly in a mining frame than a chassis where you almost have to go to Delta level airflow to get decent thermals.
3. If your considering doing CPU as well as GPU compute spend the money up-front on fat processor. The 3900x is about the sweet spot. I recently did a cost analysis and the only thing that beats it are the 2000-series threadrippers if you can find them at a discount deep enough to offset the cost of a half-way decent x399 motherboard.
