Topic: Please help!! R9 290 CGMINER - page 2. (Read 21777 times)

Ok thanks, ill give that a try.

Why does removing and reinstalling seem to work I wonder?

I was going to try uninstalling 13.12 and reinstalling 13.9 and then trying the 13.11 beta drivers.

Which ones are you using?

You need to uninstall Catalyst Control Center completely, uninstall AMD APP SDK if you have it installed.

Google "how to completely uninstall AMD drivers manually" and follow the steps. (I don't like driver sweeer or other automated sweepers.)

Download the CCC Beta installer for R9 series cards and when you install DON'T FORGET TO RUN AS ADMINISTRATOR. I had a similar problem and that's all it ended up being...

I also have Sapphire R9 290. My computer crash if I exit cgminer by pressing q, however, clicking x works fine. I don't know what the problem is.

Tried on two different motherboards, Z87 MSI and Z77 Asus.

Hi wondred if anyone on here had any idea what may be wrong with my R9s (Sapphire)

The plan is for 5 on one board, I have 10 in total and 2 boards.
I am waiting for powered risers to come, so only tried 3 in one board. I used 1x risers to connect all 3.

Now connecting one card works fine, connecting 2 cards to the 16x slots (with 1x risers) works fine too and boots to windows showing the bios screen and everything in between.

Adding a 3rd card makes the screen blank until it gets to Windows where it appears. It does detect all 3 cards in device manager OK.

Now with 2 cards installed I can mine with similar settings to those in these posts with about 830 KH but every time I quit CGminer I get BSOD with ati driver error. Perhaps it's the 13.12 new driver I upgraded to?

If I install the 3rd card, CGminer opens but almost as soon as it starts, Windows goes to black screen and BSOD restart.

I am at my wits end with it. Not sure what it could be other than these:
- 13.12 drivers? Maybe roll back to 13.9 but do these work with the R9 290?
- Powered riser required for 1x PCI slot and not enough power crashing the card?
- Incompatible motherboard? I am using Gigabyte Z68AP-D3 with celeron 1155 processor and 8GB ram. Although with the same motherboards i have rigs set up running 3 x 6970 and 3 x 6950.
Funnily enough one rig with 1 x 6950 and 2 x 6970 only shows the screen when it gets to windows and is blank before that.
- Maybe the wire to short the 1x PCI slot, but I am using the 1st slot which doesnt usually require that wire, and also Windows does detect it as a card.
- Maybe the R9 isnt supposed to go 3 way?
