When you overclock DDR5 memory to the point of causing errors, it will perform error corrections and cause you to lose performance. You may also be running out of power from the PSU causing the GPU to throttle down.
Are there any reasons as to why it will be performing error corrections? I have a Corsair AX850 Power Supply and only have a single GPU Rig.
My CPU is being water-cooled, and on maximum load (running Prime95) at 4.2 it peeks at 49 degrees Celsius.
Could there be any performance alterations to the Power options that I should make? What voltages are ideal for over-clocking a GTX580?
