Dedicated Folding Rig Questions

post #1 of 17
Thread Starter 
So I have some extra parts and was thinking of building a dedicated folding rig. =p

Some spare parts I already have:
Thermaltake Full Armor+
i7 3820 LGA 2011
4x4gb GSkill Trident X 2400
2x EVGA nVidia 260GTX
Thermaltake 750 Watt Power Supply
3x OCZ Vertex 2 SSD's 80GB

I still need to get a motherboard and was thinking I make get 2 - 4 more current gpu's on the low end that have more cuda cores.

Ideally I would like to get 4x 640GT's or 4x 650TI's. I was looking at:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814127686
http://www.newegg.com/Product/Product.aspx?Item=N82E16814127725

I am wondering if the 750 watt psu is going to be enough?

Any recommendations on an LGA2011 board that I could pick up cheap? Also I am not above buying used lol. Especially for a system that's gonna sit in the corner of my office. =p

I was looking at a gigabyte board:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128532

It was the cheapest I could find with 4 PCI express 2.0 slots.

Depending on how much I have to shell out I may end up using the 2x 260gtx instead of getting 4 of the same cards. I'm trying to go as cheap as possible so any recommendations anyone with more experience with gpu folding etc are appreciated. =p

My budget is gonna be around 500$ Max.

I was about to recommend the ud3 and I think that is the best choice for you.
The problem I see with quad 640s is 300w running from the 24pin on your motherboard. Its not gonna be pretty. I would get 650ti so you can plug in external power.
750w is enough for 400w of gpus and a 3820.

Hrm, I was thinking something along the same lines. Getting 2x of the cards that are a little more and just using the 2x 260's until I upgrade.

I was also thinking about upgrading the 2x 560ti's that are in my machine. So I could get 2x 650ti's for the folder and then move my two 560ti's to it when I upgrade. =p

Does more cores always equal better ppd? Should I be concerned much about the core clocks or memory bandwidth?
post #4 of 17
Yes more cores do help, and overcloxking does as well. Ram speed also helps, and at 2400 you've got it pretty good.

Well, actually I have a GTX 260 in my rig now, lol, I'll go see what kind of points it gets just for a benchmark type thing for you.

If you're serious about running 4 GPU's and a CPU 24/7 in this rig, budget is not the word. The cards are going to be going full fan speed most likely, or fairly close to it, especially if they're older cards.

Maybe consider having a machine with just 2 higher end cards, such as 580's or even 7950's. Even with 3 GPU's I'm thinking the system will be running fairly warm without water cooling..

EDIT: With my GTX 260 under water I'm estimating it'll get around 7-8k PPD, keep in mind that's on stock clocks as well, and temps aren't above 53C. smile.gif

If I were you I'd try and sell the GTX 260's and maybe go for one NVIDIA and one AMD card. I've heard horror stories of running both brands and their drivers together, but I've run my 7850 with a 670, and the only problem I had with dual montors was moving a Minecraft screen from the 670 display to 7850 display would cause a BSOD, but they folded together great. smile.gif

So maybe sell the 260's and save a bit for something like a 79xx series card (7950's can be bought for around $270 new now, with a few free games that can be sold easily for around $30+) and a 6xx series NVIDIA card. Currently a GTX 580 is the top dog for NVIDIA, but with Kepler's newer technology, I'm thinking Kepler might get further optimizations putting the 6xx cards on top.

Not hardly, I just have a lot of leftover parts from upgrades. I have an 1090T and an Athlon X2 4800 system as well. I just figured it would be a fun project to put some of the stuff I have laying around to good use. smile.gif

I have 4 old phat ps3's that have bad bluray drives. (My kids like to stuff change in them, lol.) I was thinking about installing linux on them and setting up a small cluster. thought it might be pretty neat.

I have a few of these laying around as well.
http://aaeon.industrialpartner.com/compact-board/pcm-6897-a10-02.htm

Not sure where I acquired those. I think they are Pentium III's and have 256mb ram. biggrin.gif



PS. My wife thinks I have issues with hoarding. lol.

Thanks for the advice.

I'm thinking I may just run with the gpu's I will have on hand. I should be finishing up a job in the next month and I am starting to really want to upgrade my 560 ti's. I haven't decided whether I wanted to go with 660ti's or 670's yet but I wanted to keep an sli setup. then I could run 2x 260's and 2x 560 ti's in the folding rig. Would give me a chance to get the system put together and see how it performs and make some adjustments before I decide what to replace the 260's with. No matter which way I go I am really wanting to have 4x gpu's folding so I may need to invest some of the budget into cooling before upgrading the cards.

For the processor I was thinking about going with an H100i. Definitely performs better than air cooling and would allow some better airflow in the case.

Instead of a H100i, try to get a Swiftech H220. It's basically an AIO, except can be easily expanded into a full blown custom loop. thumb.gif And they're fairly cheap, $140 for a 240MM unit.

Cool, I was looking at the review on martins liquid lab. It looks like a solid kit. =p
