Iv use gigabyte cards and have no problems at all but Im back at the 9800's not the newer stuff.

Are you guys sure your CPU is not throttleing down to save power?

These kinds of problems are video or system ram 9 times out of 10.

Switch your system rams around so that the ones that are now in the high adress are in the low address and see if the same thing happens. If it gets better then you know one set of your rams is bads.

If it does not happen outside of games that is an indication your high adress rams might be bad.


Otherwise they just got a batch of bad video ram ....
