HD 7970 matrix platinum artifacts

[Kakostox]

Hi,I've got a lot of artifacts on stock clocks on hd7970 matrix platinum on heavy load of games(BF4,COD Ghosts...).I made a research on google and found that is the Vram the problem. From 6600mhz I downgrade it to 6300mhz at same stock voltage (1.6volt) and I got no artifacts now.Also I try a lot of kind of drivers from asus and amd and is not the drivers the problem.My question is If i stick to 6300mhz vram will my card get damage or the in future get again artifacts on 6300mhz? Should I RMA it? Thanks

RMA it asap, it is faulty.

ok,i made a quick search for postaging from Cyprus to UK and will cost me (200+ euro) I cant RMA it.. So if i stick to 6300 mhz may my card die one day..?

It won't die. The reference memory clock speed of the 7970 is 6000Mhz. Yours is still faster than that. Just stick with it if it costs too much to RMA.

is the matrix platinum edition..the stock clock is 6600 mhz.

Stock clock doesn't necessarily have to be the same as reference clock.

Reference clock = The clock speed set and recommended by the GPU manufacturer, AMD. All cards should run stable at this speed.

Stock clock = Set by the card manufacturer, usually faster than the reference clock. Risk of GPU becoming unstable.

ok,that a good info.The bad is that i pay for the matrix edition and is unstable.How do I know if my card is stable at 6300mhz? I test it with OCCT program(http://www.ocbase.com/) and I get a lot of errors even in 6000 mhz.Is that program reliable?

Looks like you got a bad card. Keep lowering the memory clock till you get no errors.
