F@H questions

post #1 of 14
Thread Starter 
OK, so I am going to build a folding rig. So far specs are

Phenom II x4 965BE
4GB DDR3
Nvidia GTX 560 (pending purchase)

This rig will be dedicated to folding. I want to get as much out of it as possible. However, I still want to be able to administer it (remote desktop, view stats, etc.).

Should I keep one core of the CPU idle for this?

How do I prevent SMP from using all the cores?

Will folding slow down internet connection speed (Work Units going in and out)?

What is the best bang for the buck GPU for folding under $250 (I have a 750W (the one in my sig rig) PSU for the whole PC, so power is no issue)?

Thanks for the help.

It should not be necessary to hold a core back for remote desktop, although it may be necessary to do it for you gpu.

to stop one core from folding you will just add the "-smp 3" flag, the three being the number of cores you want it to fold on. To specify which core to stop, you can use a program called AFC
.
You internet will take a small hit (or larger if you game) when a WU is uploaded.

Right now the 460 768mb is the best bang for your buck. They can be had for about $130 open box and when overclocked can net you 11.5-12.5k PPD.

Thanks for the info. so far. Are there any spreadsheets for AMD avg. PPU values? I saw a thread with Intel ones, but they didn't have any AMD ones listed.

If you look at the top of the spreadsheet there's an AMD tab.

And the 460 is a great bang for buck, but the 9800GX2s give 13k (when OC'd a little) and are about $90 used right now. They're folding MONSTERS.

I was looking at those, but someone recommended the 560 because it got like 15.5K PPD, but I want to spend as little coin as possible on a very good card.

You might want to investigate TeamViewer if you're planning to remotely access it.

Remote destkop has a nasty habit of resetting the GPU driver, which causes the GPU WU to fail. This makes folders sad.

To be honest, I would simply set the SMP up as -smp, and the GPU up as normal, and let them fold. I haven't seen any benefit to allowing the GPU one whole core to itself, Windows manages itself pretty well without the need for it.

To remotely view stats, you can setup HFM as per the guides here somewhere on your main rig, then samba share the folding client work directories from your folding rig over your network, so you can see them and add them as clients on the main rig

Remove all unnessesary services, leave just TeamViewer, HFM, and the clients open, and forget about it.

^ omega is spot on.
Though the Fermi cards sometimes are better of having a thread to themselves, but OP isn't using one just wanted to point that out.

I'll just post the links.

Setting up HFM

Remote monitoring
HFM remote monitoring
Or
Dropbox HFM remote monitoring - This one seems easier to me


Remote desktop
Teamviewer
or
Logmein - I find LMI better than TV for personal use.

Would you (anyone) run antivirus on it if it's just for folding?
post #9 of 14
No.

Seems silly to have it since all it is doing is transferring information with Stanford and they will not send you anything harmful.
Unless you start browsing on it and look at sites that can get you infected you should be fine without one.

I'd just stray away, if it's not browsing the internet you won't be getting viruses and it may just interfere with your folding.
