I am trying to free up some CPU% while using SDRC with the RX-888 and hoped to gain by enabling CUDA on my GTX580 Nvidia graphics card. The GTX580 is old (~10 years) but does have CUDA (confirmed in CUDA diagnostics). However, when I enable CUDA in SDRC the Plan appears as IPP. On my son's computer with a more recent GTX card CUDA is activated and frees up a load of CPU% I have the latest Nvidia drivers.
So the question is am I missing something obvious or is it simply that the GTX580 is too old and I need to purchase a better graphics card?

Hi Dave,
Does the GTX580 meet the requirements?

Attach the logfile - it'll show me what's what.
Re: GTX 580 CUDA not working
Barry, you are right the GTX580 does have CUDA but is rated as 2.0 compute capability so doesn't meet the SDRC requirements (3.0). So it looks like a new card is needed. Not sure how I missed this.
Simon, I have my answer, but I have attached logfile anyway. It is only the RX-888 that gives me CPU problems, ANAN and Airspy HF+ work fine.

Ah,
My notes have a reference to this: https://docs.nvidia.com/cuda/cuda-c-pro ... pabilities
Seems that 3 is needed.

Re: GTX 580 CUDA not working
1650 Super looks v. nice but a bit pricey for me! Probably will settle on a GTX 950 or similar.

I have a 960 & 970 available...
Re: GTX 580 CUDA not working
Ahh...I saw this too late! I bought a 970 from eBay earlier...
Sorry

No probs!
Re: GTX 580 CUDA not working
Hi Simon
Seller let me down...
Do you still have the 970 or 960 available?
