This could be better as a comment, or if you expanded upon it more a complete answer.

@Tony that's true but it is way better for a user to gain the small amount of rep needed than to create short and incomplete answers.

It's pretty short, but at least gives a suggestion how to fix the asker's issue based on personal experience. It could be improved by providing a description of the problems that the answerer had before  applying his solution.

# cgminer with two R9 290 giving me headaches

(Asked by: username_0 on 2014-02-06)

I've got two R9 290, using cgminer I'm getting nothing but trouble. I'm using the 13.12 driver and installed the 2.8 SDK.

When I launch cgminer it sees both cards, GPU0 and GPU1. They both happily start mining, but after about 30 seconds cgminer hangs for a few seconds and GPU0 starts dropping its hashrate (it gives HW:1). I'm not sure what's causing the issue since both cards are identitical and I've only defined the settings once using `-g 2`.

I've seen that there are some difficulties with the particular card (had to define --no-asl to stop it from crashing the display drivers). Does anyone have any tips or clues to find the problem?

I'm running two Gigabyte R9 290 with an i7-930, 18 GB memory and a 1000w PSU on Windows 7 professional x64.

Is there an alternative to cgminer for ATI cards which can succesfully use the ASL api?

I managed to fix this by using the [kalroth patched version of cgminer 3.7.2](http://k-dev.net/cgminer/). Sometimes my cards still black screen after rebooting the mining process, but generally it runs quitestable once started from a clean reboot.
