I think i may of missed telling you that i am overclocking my Gefore FX 5900XT.
I have read up on this and have changed the core clock Frequency from 300MHZ to 474MHZ and the memory clock from 700MHZ to 870.
The other tests work ok so why should it fail on the cpu test on 3D mark, what has the graphics card have to do with the cpu can you explain and maybe give some suggestions i could try. Im not worried about frying this computer as im getting another so any help would be good.
Could it still have somthing to do with the ram sticks. i have set it to no overclocking and i still get a freez on the cpu.
But im keen to overclock this card as ive read alot that it is good fro overclocking.
