Back again and ready to build a folding system

Hello again everyone. Been away a while and am considering getting back into folding again. Any hints on the best, low cost options for it?

Give us a budget, and will you be reusing any parts from a previous build(s)?

The GTX 1070 is the current PPD per $ king last time I checked.

Welcome back! I'd say definitely focus on video card folding.

No to reusing parts, as the systems I had it on are totally dead. I hadn't yet decided on a budget, either to be honest.

GPUs are definitely the way to go.

In addition to the 1070, consider looking at used previous generation GPUs. In my area on Craigslist there were two 970's for sale for $260 ($130 each). That's ~700k PPD right there. A few months ago I picked up a 980 Classified for $275; it regularly gives me 500k PPD.

I buy motherboards that can accommodate 2 GPU's (easier to fund a second GPU than have to build another system), large case for great airflow (I favor the CoolerMaster 912 HAF; great airflow, plenty of room, and $59 on Amazon), a left side panel 120mm intake fan, a front panel 120mm intake fan, a 200mm exhaust fan on the top of the case, a decent 750-850w power supply, small cheap ssd, 4gb cheap ram, Win10 (I really wish I could get some strain of Linux to work as you'll get more PPD on Linux, everything else being equal).

The one system I have with a single 980 was built from leftover and a few new parts.

I try to balance each system with a more and lesser powered GPU so I don't overburden the power supply (I don't game at all so I'm focused on optimizing for folding). So I have three 970/960 systems, a 980/750ti system, and the aforementioned single 980.

The two GPU systems run ~ $500 (case, mb, fans, ps, ram, ssd, OS) plus whatever GPUs I can find on sale or lately on Craigslist. Subtract $100 if you know how to run Linux.

I don't go cheap on the case or power supply because these systems work very hard 24x7. I don't need a mishap because of cheap hardware.

Well, here is a link to a build I am thinking about based on the feedback so far: https://pcpartpicker.com/list/dhfKkT

Any comments would be appreciated.

Are you going to use this setup for anything other than folding? Otherwise you'd be better off redirecting the CPU cooler $ to a better gpu. GPU folding gives you at least 10x more PPD than CPU folding, even if you're overclocking the CPU. Also an aside - with GPU folding, each GPU will automatically grab one core of the CPU.

I did not spend too much time investigating CPU folding because the folding performance difference is levels of magnitude, added more heat to my office, and cost is in the same range as a decent GPU, but my recollection is:
i3: ~10-12k PPD
i5: ~15-20k PPD
i7: ~25-35k PPD

This is what I typically see from my GPUs:
960: ~160-180k PPD
970: ~300-350k PPD
980: ~435-500k PPD

The range of PPD above varies on the work unit, any overclocking, etc.

So that's why I don't bother with CPU folding. Four of my machines are 100% dedicated to folding; three have i3's, one has an i5 my son discarded after an upgrade. The fifth machine is 90% folding and has an i7 because I use it for CAD and also as a media server.

Will you be folding 24x7? If yes, you may consider a better power supply that will put up with the stresses of constant work. I had an el cheapo power supply catch fire on my first folder and luckily I was there to deal with it! Scared the hell out of me. After that, no more cheap power supplies.

If you are looking into the AMD GPU space I am folding on a single i5-6600k Skylake system with an Radeon RX470 4GB. so figure I'm getting 15-20k on the CPU and 260K on the RX470 which was onsale for $180 around Thanksgiving.

I agree with gregaber, get a CM hyper 212 Evo or something like that, and put more money into the GPU, 1070, and a beefier PSU, EVGAs are good, just get a bigger one, 650 or so.

Well, the build I linked to is based on the Media/Backup server build I had started, so I can adjust as needed. I also do some pretty intensive image rendering, so I did think about possibly using the machine for a remote node for that, though not on the GPU when folding.

AMD GPUs are good at a lot of things, but they are NOT a good choice for Folding (that might change on the VEGA line, but the Fury line wasn't all that impressive in it's day so I'm not figuring VEGA will be that much better).

1070, 1080, and 1080ti at the SYSTEM cost level are pretty much a tossup on PPD/$ since the recent price reshuffle by NVidia when they introduced the 1080 ti.

1070 - 600K PPD or a bit more.
1080 - 750k PPD or a bit more.
1080 ti - BY REPORT 1150k PPD or a bit more.

1070 and 1080 figures are what I see on my own rigs with a VERY mild overclock.


Most of my rigs are 3-card "mixed" rigs (I am close to my 20 year anniversary with the Distributed.Net project, Febuary of next year) so the following isn't an optimised "folding-specific" rig and the CPU is severe overkill for such a rig.

A10-7860K or A10-7890K (on pure folding rig, go for the cheapest quad-core A-series or possibly duo-core you can find, I use these for the higher-end GPU that runs RC5-72 via the Moo Wrapper and BOINC quite efficiently).
2 x 4GB DDR3 (usually 1600 since that's normally the lowest cost)
ASRock FM2A88X Extreme 6+
Seasonic X-850 (EVGA G2 850 is another good choice here)
2 x "full length" Gigabyte 1070 (not usually the G1 but the next step down, when it's on sale for $379 at NewEgg)
1 x "ITX" Gigabyte 1070
A pure folding rig CAN run from a USB key, but a small HD lets it boot up a lot faster and saves a LITTLE "download" and "upload" time. SSD is severe overkill, but if you find a small one cheap enough they work fine.
Most of my folding rigs are on 500GB or older and smaller HDs (ONE is LINUX on an "overkill" Sandisk 128GB USB).
I *think* you could run a LINUX pure folding rig from an 8GB USB and definitely from a 16GB, Windows takes quite a bit more space and would need at least a 32GB - and you almost HAVE to use 10 for a USB key setup.

I'm moving to using a pair of 1080 in place of the "full length" 1070 cards on future rigs, as the increase in power consumption is minimal for a significant increase in PPD, since the recent price drop on the 1080s.

The "ITX" card is used to allow the middle card to have unrestricted airflow on ONE fan (the other fan(s) are blocked badly enough they get almost NO airflow and the card don't stay cool that way).

You can go Intel instead, the costs will be similar but you have to DIG a lot harder to find a motherboard with 3 x PCI-E 16x slots in the under $100 range. Whatever the bottom-end G-series quad core Celeron (or possible a dual-core) would be enough CPU for a pure-folding rig. DDR4 still tends to be more expensive than DDR3 but it's getting a lot closer of late.

You could go AMD AM3+ instead for around the same cost or perhaps a little less - use the ASRock 970x Extreme 4 motherboard and a low-end 3-4 core AM3+ CPU (might be able to get away with a 2-core but Folding recommends a full CPU core per GPU for full throughput) - that setup would use the same RAM as the FM2+ setup.

If you don't like ASRock, I do have one rig with the ASUS A88X-PRO.
Motherboard works just as well, but I didn't like the BIOS configuration as well and it is usually a bit more $ than the ASRock.
