Hello, I recently changed my computer today to do some tests with 3dmark on the new computer I found that the graphics oc is not stable. Old PC: - Q6600 @ 3.2 - Asus P5K-e - Thermaltake lite power 700w - Msi gtx670 oc edition power New PC: - 3570k @ 4.2 - Z77x-UD3H gigabyte - Thermaltake lite power 700w - Msi gtx670 oc edition power This is the OC I had before and no problems Now in the new pc this is the most we've gotten What can it be? Could it be the PSU? I have seen with the GPU-Z to change the values afterburner, I formatted the PC a few times if software issue. I changed drivers but the result is the same. THX!
