Message 1238 - Posted: 24 Oct 2019, 14:04:48 UTC

So I have dual GTX 970 cards but only 1 is running at a time.

How do I adjust the setting to run 2 wus, 1 on each card.

Thanks for any advice.

Situation has changed. Now a 2nd wu started but stopped in less than a minute and says "waiting for memory".
My memory settings are 90% of memory regardless of computer being or nor being in use.
Any ideas on solving this?

Hi AT Hiker,

Your computer has 16GB RAM so you are able to run a single GPU task only. You will require 24GB to run 2 tasks and 8GB more for each additional GPU task you run.

This is because each task uses 8GB system RAM and your system will be using a few GB during normal operation, along with usage from other programs you may open.

Regards,
Kellen

Try increasing your virtual memory, that should solve it but you will have some system lag here and there from it.

Start reading here for new 10^21 tasks:
