GeForce GT 540M

Post by Staniol »

Hi!

I'm not a hardware specialist so excuse me if I'll make any mistakes. I have a Samsung laptop and I am successfully folding on both CPU and GPU. However I have a few questions concerning my graphics card - NVIDIA GeForce GT 540M.

This is what GPU-Z states:

I don't understand why it shows CUDA as unavailable. The specifications clearly state that CUDA is supported. May it be a GPU-Z bug?

This is what FAHClient.exe --lspci states:

So as you see, the folding starts and performs ok on both CPU and GPU.

My question is - should the GPU.txt file be updated with a proper name of a graphics card? If the vendor code was badly recognized till now, should it be further investigated about using a different core? What do you think?

Re: GeForce GT 540M

Each type of hardware has an internally encoded identifying number which identifies what its capabilities are. According to GPU-Z, that number is 10DE-0DF4. FAH uses that code to determine which capabilities to use. It doesn't matter whether the person selling the hardware identifies it as a GT 540M or as a GT 555M SDDR3.

According to NVidia, the 555M appears to be a class of GPUs which can be customized by the manufacturer to a specific clock speeds and a specific number of cores and with a specific memory interface. Functionally, the FAH software does not really care which one you have. http://www.geforce.com/hardware/noteboo ... ifications.

We can probably get GPUs.txt updated to say "GT 540M" instead of "GT 555M SDDR3" but it is a name change that will not change the capabilities of the hardware or how the software interfaces with it. It looks to me like the 540M is just a single customized type of GPU within the range of capabilities spanned by the 555M family.

The GF108 is about 1/2 as powerful as the GF106

Both 106 and 108 are classified as gF cards and thus use the same fahcore. They both fold the same way, one is just faster.

The various OEMs use and re-use similar chips with minor description changes. As long as the class (fermi) is the same, the description in GPUs.txt will not be updated unless obviously wrong.
