Topic: WTF? New R9 290's not recognized (Read 1567 times)

OK, so here's what did to get it working. I reset the MB bios to stock settings and reinstalled the chipset drivers. That seemed to do the trick.

Now I have them all screamin' at full bore. Thanks for the suggestions zen.  

may have fried your pcie ports too - try different ones.

I had the same cards but had to RMA them. I fried them by hot plugging the DVI cable while it was mining. I always thought that was cool to do, but I guess not. After that, I may have reinstalled win. But regardless, I'm thinking this is not software, since BAMT doesn't recognize them either.

You had it running 3 before? What did you change?

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.
