GUIMiner with twin R9 290s

[wpalczynski]

Hi Guys,

Could someone please let me know what GUI Miner settings I should be using for my 2 R9 290's.  Its running at approx 650 khas/s.  Almost like its only using one card.  Your help is greatly appreciated.

Regards!

It seems that only one GPU is being used.  Only one is hot and has the fan on high.  When I start the program before it starts hashing i get the following error:

Error -1: Getting Device IDs (num)

Help please!

Try using a mining program that isn't over a year out of date would be a start.

Try this settings:

My GPU: R9 290X
Device: Hawaii
Thread concurrency: 28500
Vectors: 1
GPU threads: 1
Stratum: Yes
Worksize: 256
Intensity: 20
GPU Defaults: 7970 (High Usage)

My results: 934 khs

Just adjust your TC that suite yours.
