Hey everyone. I have been having an issue with my cards, but I am sick of hijacking other people's threads so I thought I would make my own.
I get very unstable and/or low fps in the games I play with my Powercolor 7870LEs. I have noticed that one of my cards is clocking at 501/1550 while the other one jumps between 900-925/1500.
I have tried overclocking them with CCC and Afterburner. I have installed several drivers. I have used driver sweeper in between installs to ensure that is not the problem. I have disabled crossfire and re-enabled. I have the power set to +20%.
It appears it is stuck in a dual monitor 2D speed. One of the cards doesnt even seem to be taking the overclock because it is stuck at stock speeds. Usage is very very spiky between the 2 GPUs during gaming. It is not evenly distributed AT ALL like it was on my previous 2x 6950 setup.
To get an idea of what we are talking about, my 3dmark 11 score is P9211 with both monitors enabled. With just one monitor enabled it jumps to P11920, but still the core speeds jump around and will not hold the full speed during the run. I know 3dmark scores dont really hold much weight around here, but the difference is staggering and shows an obvious correlation.
So my question is, does anyone have any experience with how to fix this? Is there a way I can force constant 3D clocks.
Any input is greatly appreciated!
