Folding Forum

Hi, I have the opportunity to get three old Nvidia Quadro 4000's. The Internet shows inaccurate info about it being still supported or not. Can I still fold with it (even not very efficient)?

Someone posted here recently that they were getting assignments for a Quadro 4000 they have.

You can download the latest GPUs.txt file from here - https://apps.foldingathome.org/GPUs.txt. Entries with non-zero and non-blank values in the third and fourth fields are still on the whitelist, those with zeroes or blanks in those fields are blacklisted. That said, they are in the process of realigning how WUs and projects are assigned to various types of GPUs, so this may change in the future. What the minimums will be may change.

In the case of the Quadro 4000, it supports OpenCL 1.1+, so works on many but not all projects that use GPU folding cores that were coded to the OpenCL 1.2 standard. Latest word I have seen is that as it is Fermi based the Quadro 4000 will not be able to use CUDA processing in the latest version of Core_22 and will fall back to using OpenCL.

Thank you very much!

One thing I would add, I would not pay anything much for these Quadro 4000 cards, but if you are okay with the electricity cost to use them they can be used for a while. Otherwise there are a number of more recent cards that can be acquired for not too much that will out perform the 4000s.

Initially that's why I even bothered to ask. I didn't find any threads with the original 4000's in this forum, but I did find threads with K4000 models. Just now able to test one of them, but I didn't get any assignment (yet?). By the way: I can get those cards for free. Otherwise they would end up as electronic waste.

It's almost all in the letters. I see 15 different Quadro 4000s that we list as supported.

The [Quadro K4000] uses the GK104 (Kepler) chip and is currently classified as GPUSpecies 2. The [Quadro 4000M] uses the GF104 (Fermi) chip and is classified a GPUSpecies 2. The [Quadro K4000M] uses the GK107 chip (Kepler) and is classified as GPUSpecies 3. The [Quadro K4000] uses the GK104 (Kepler) and is classified as GPUSpecies 3. THe [Quadro M4000] uses the GM204GL chip (Maxwell2) and is clasified as GPUSpecies 4. The [Quadro M4000M] uses the GM204 chip and is classified as GPUSpecies 5. The [Quadro P4000] uses th The GP104GL chip (Pascal) and is currently classified as GPUSpecies 5.

I could go on: [Quadro P4000 Mobile] [Quadro RTX 4000] [Quadro RTX 4000 Mobile / Max-Q] as well as [Quadro FX 4000] [Quadro FX 3450/4000 SDI]

The Species will be realigned based on benchmark testing. The project owner can decide toinclude/exclude specific ranges of GPUSpecies.

As has already been suggested, I would avoid those that support OpenCL 1.1+, not 1.2, and those listed as Fermi.

My cards use the GF100 GPU. Looking forward seeing those things fold in the future

Fermi GPUs will not be able to run CUDA. OpenCL should still work if FP64 and OpenCL 1.2 are supported.

Then nVidia code that permits Core_22 to support almost any modern nV GPU considers Fermi too old to support.

UPDATE: I indeed got an assignment for one of the Quadro 4000's (FahCore_22). The other two turned out to be broken. Anyway, thank you for the answers
