I also have similar problem with 2x 280x. One card is hashing but the other one is not disabled but hashing only 10kh/s. Do I need to upgrade memory to 16GB?

You can launch one miner per card to make sure they work fine and there is enough memory.

Should I have to check the memory status in task manager? And if there is not enough free memory should i buy more? I do not have problem with upgrading just asking if this will help. Thank you

EDIT: I have 8GB right now.

Start one miner copy with -d 0 and another with -d 1 to see if they work fine.

One miner with -d 0 and -I 16 in still not hashing but consumes more than 2GB free memory, and if I run only the seccond miner -d 1 and - 16 it is hashing fine and consuming almost nothing from free memory.

Reduce intensity and/or clock speeds of the failing one.

Yes with reduced intensity (-i 15) it was working. But I still do not know why card 0 alone consumes almost 2GB (hashing 10khs) and card 1 alone only 0,02MB (hashing 500khs). It looks like that Windows was in some strange state because from 8GB total memory, 4,4GB was used sa Cached and 2GB free. Anyway I have added another 4GB and it looks fine also with intensity i 16. After a half day is the cached memory again 3,5GB and 3GB free. Now it is hashing fine. Thank you for help

I have another question. What is the hashrate for 280x and for 290 (non X)?

About 500KH/s give or take. Maybe closer to 550KH/s for 290.
