mining cards.. and how they work.. or utilise on board memory

[rocksalt]

hi all,

question:

does it matter for a mining card to have 1gb or 2gb ram? i assume as were underclocking ram, we're not that interested in the usage of the ram.... more pushing calculations directly into and out of the GPU's so if i got a 5830 with say 512MB ( don't ask ) it would really matter as it's gpu operations im looking at.

Am i right in thinking this?

RAM doesn't affect mining performance. RAM however affects power consumption, so if you're only mining, get a card with as little RAM as possible.

cool.. i thought as much....  nice to get a confirmation
