Try updating the drivers to Radeon Software 21.1.1 and see if that helps. I've seen Windows updates that revert the drivers and break some things. Running the Radeon Software software may even say you have the wrong driver version when that happens.

I'd suggest getting a replacement power supply. Many people don't realize that power supplies can degrade over time, and if the load is high, they will degrade faster than if you give yourself a lot of extra room. If you add up the power draw across all of your cards, then add 200W for the rest of the system overhead, you then want an extra 200W on top of that to play it safe(so spikes don't pull more than the power supply can handle).

Hi,

I've been mining for a few months now with no errors. All of a sudden I'm getting a clSetKernelArg (-48) error...see below:

Code:

Does anyone have any ideas?

Thank you.

Its possible but I have the cards distributed over 2 power supplies. Total draw is 550w and the power supplies are rated at 1600w. So I've never been close to their limits. I'm really stuck!

You were right. Updates turned off but somehow Microsoft had performed an update which included driver updates for AMD and NVIDIA. I was lucky and a 'restore to previous point' process worked and I'm back up and running. Thanks for the help!
