Folding Forum

Greetings and salutations,

Is it possible to add support for an nvidia GT215 series card. I have the nvidia 340xx drivers installed with xorg 1.20 and a 5.5 linux kernel. This computer does nothing so am looking yo assign it some full time work!

Some logs:

Hope it can be added,

Thank you.

The T in GT215 stands for Tesla, an ancient micro architecture no longer supported in F@H.

The Tesla was good at Core_15 and still worked in Core_17. (badly)
Today Core_21 is slowly being replaced by Core_22 and Tesla has been 'extinct' for years.

No, it is too old and based on the Tesla micro-architecture. The oldest nVidia cards that could be used were based on Fermi, and you probably need one based on Kepler to complete current projects within deadlines.

In addition all current projects require GPU's that support both single and double precision calculations.

Thanks for the speedy reply! Ah ok thanks!

You could still run a GT730 (I tried it).
Though I wouldn't use anything lower than a GT1660 or 1660Super or Ti, due to older GPUs performing pretty inefficient.
But a 730 still works, and is about as fast as a quadcore 3-4Ghz CPU

There are several different GT 730 cards that were sold. One was based on a Fermi GPU and has few shader cores, it might not finish WU's in time. The others were based on Kepler and have more shader cores.

I'm still running a GTX970, and it's good for as much as 450k PPD, depending on the project. On any given project it gets a bit more than half the points of my 1660Super.

OTOH it uses over twice the power of the 1660Super (275W vs 125W), so yeah maybe not the best in terms of points per watt. In fact, when I do the math, that card running 24/7/365 is costing me about $180 a year vs $80 for the 1660Super. So I could earn back the cost of a 1660Super in a bit over 2 years in reduced electricity costs and get more folding done at the same time.

So maybe an upgrade would be worth it. Thanks for making me think about that.

I second that comment.

The ":0:" just prior to the "GT215" in that string denotes "unsupported". Did you get a message in your log telling you that?

As the line in the GPUs.txt file is actually the following I am assuming you modified the downloaded file. As was mentioned in the topic you first started out in asking about the GPUs.txt file, user modifications to the file have no effect on how a GPU is treated by the servers. They only manage to confuse the client, and may allow you to force creation of a folding slot for an unsupported GPU.
