Is it worth folding on a low end computer?

post #1 of 18
Thread Starter 
I don't see a general folding "lounge" so I decided to create a new topic. I am putting together a low end computer using second hand parts that I could get my hands on. So far I got a 775 board, a Core 2 Duo E6750 and 2 GB of RAM (no video card yet, I will probably just buy a cheap $30 video card somewhere). It doesn't have a specific use yet so I am thinking of folding or doing boinc. Now is it worth using this kind of machine? I am asking this because when I browse other people's folding machines, they are way better than my own main rig lol.

All points help the end cause... but that rig wouldn't contribute a whole lot, especially if you compare its PPD to its power usage, and then compared those numbers to other rigs.

If you can afford the extra power bill for not much of a cause, then go for it, but I think it might make a better HTPC/Netflix box or Linux machine to toy around with IMO

it will probably only get about 5k ppd stock but every little bit helps

Yeah, that's what I'm thinking, it may not contribute a lot to justify running it 24/7. I may get a GTX 460 or something but still don't know if that would matter. Thanks for the input guys biggrin.gif

A 460 would be 8-10K points per day... and the CPU points per day would drop off quite a bit because the CPU would be using cycles to run the 460's folding activities... but it's basically all about whether or not you feel good about what you're contributing. Any amount helps the cause, so unless you have a better use for the PC and the power it's using, then go for it smile.gif

I can tell you from experience that it will work just fine and do well at gpu folding. I have a EVGA 780I SLI mb/ 6700 cpu(I think) with a GTS 450 and works great. I just bought a second GTS 450 for $50 from the OCN Marketplace. I would not recomend folding on the cpu.

Best use of that CPU would be to use it to feed a GPU.

If you can find a deal on a GTX 460, they are definitely nice little cards to fold on, even a GTS 450 isn't bad.  With an OC'd 460 you should be able to get up to ~20K PPD with the current Work Units.

This is correct.

This is incorrect, Nvidia cards use very little CPU processes while folding and will easily more than make up the small amount of points lost.

Agreed. It may not be worthwhile in terms of efficiency to fold on the machine now, but it's also nice to have a machine around that you can throw a dedicated GPU in to fold. If you do that then it would be come viable to fold on the CPU in addition to the GPU IMO.

Okay, I was unaware that Nvidia cards had very little impact on the cpu's ppd - AMD is not the same story, I know this from experience so I was under the impression that Nividia cards had the same effect. I've never tried folding with my 670, just my AMD cards.

Also, I never said to OP anything along the lines of the GPU not making up for any PPD lost on the CPU due to folding on a 460 - so I'm not sure why you point that out - I told OP that it would be worth it if he wanted to fold. 8-10K PPD is how many PPD one can expect from a 460 - with 10K being overclocked. So on top of his CPU, about 14K PPD or so might be worth it to OP smile.gif
