^ didn't know that. Was wondering what happened to bigadv. Also wondered about 4p users since could isn't as efficient as gpus now. Wonder if those users still fold with 4p machines.

I was never exposed to the BigAdv issue so googled it and found this link that explains what was going on at the time.

There isn't a good way to influence which unit you get, and all units need to be folded so I just recommend folding all of them. Who knows, one of those that you don't like might cure a disease, and if you hadn't folded that specific unit with that specific PRCG, then it might not be cured. If you are folding for points, no offense, but it is being done wrong.

Linux offers an advantage to NVIDIA folders, it does not do the same for AMD folders, in fact for AMD folders, Windows is better.

With Linux your PPD will be somewhere around 8-12% lower with AMD cards. This has not been the case with everyone, but most people that have tried folding AMD in Linux have had issues with it. That's also partially because of AMD's bad driver support for Linux users. It's the opposite for NVIDIA, you'll see around 5-15% higher overall PPD.





Ughh - this might be me as i switched to Linux to avoid those pesky core 15's (low PPD + no QRB) and to get the 10 - 15% higher PPD on my Nvidia cards blushsmiley.gif

I think most if not all of the 2P/4P folders stopped folding completely. I never built my 2P system to fold so I don't carry such animosity towards Stanford, but it was quite the crappy decision by them and could have been dealt with better. People mostly repurposed their systems to other DC projects.

 

If you look at [H]ard's folding output you'd also notice that their output has dropped by ~600% since 2014. There was quite the drama at the time and I think most of their leaders cut ties with Stanford. It has dealt a huge blow to x86 CPU folding,

Hi there!
I wonder what GPU specs have more impact in ppd, from the list:

  1. Base Clock
  2. Boost Clock
  3. Memory Clock
  4. CUDA Cores
  5. Bus Type
  6. Memory Detail
  7. Memory Bit Width
  8. Memory Speed
  9. Memory Bandwidth

What spect(s) do we need to considere the most when buying a gpu for folding, on a short budget?

Cheers!

Maxwell changed everything. A GTX 960 with a 128 bit bus can put some good PPD. Look that up.

Hi!
Thanks by the answer...
In case of pre-Maxwell products (say gtx6** and gtx7**), what specs should i considerer the most?

Cheers.

GTX 780s and GTX 780 Tis are your best bet for Kepler based cards. The rest are definitely in their shadow.

Just a suggestion, but might be wise to include a field for driver version. They obviously can introduce huge variances, especially for Kepler and Tahiti/Pitcairn.
