I’m adding cards to my rig and am having some difficulty. I’d be very appreciative for any help. I have been running 1 R9 290 at 880khs for a couple weeks. I’m trying to add 2 additional R9 290’s, but they are not recognized by my system. The first card is still recognized and mines fine at 880khs, same as before. I can switch the cards and they each work, one at a time, but not together.
I had it recognizing 3 cards previously, but then went down to 1, now going back to 3. The cards are all Gigabyte Radeon R9 290 GV-R929OC-4GD. It shows only 1 GPU in sgminer, MSI Afterburner and only 1 display adapter in the Device Manager. I even booted to BAMT and it only sees 1 GPU.
I reinstalled sgminer and AMD drivers (after using Display Driver Uninstaller to remove the old ones). I’ve tried different risers. I've tried plugging each of the new cards one at a time. I’ve tried plugging the cards into the second 16x slot on the MB. All without success.
Thanks in advance.
I’m running:
MSI 970A-G43 8GB RAM Win 7 x64 1 Gigabyte Radeon R9 290 GV-R929OC-4GD directly on MB 2 Gigabyte Radeon R9 290 GV-R929OC-4GD on powered 1x to 16x risers SGminer 4.1 13.12 beta drivers
I am executing setx GPU_MAX_ALLOC_PERCENT 100 and setx GPU_USE_SYNC_OBJECTS 1 before launching SGminer.
My config:
