I just got myself a Radeon 5970 which will solely be used for mining, but for some reason I'm only able to mine with one core?
I'm using guiminer and I start two clients and choose [0-0] Cypress on one and [0-1] Cypress on the other, but they still only use one core? I get around 320Mhash/s, when I should be getting twice as much
Does anyone know what could be the problem here?
I should also mention that I'm running WinXP 32bit, Catalyst 11.6 and guiminer v2012-02-19.
