I thought it was to do with the ATI v8.9 drivers as well because the 8.8's I just uninstalled yesterday showed overclocked bandwidth at 140Gb/s on my 4870's CrossFire. I appreciate the people who make GPU-Z freely available, so we are all just having a bit of a dig at ATI. I thought it was funny when I looked at the figures of a GPU clock of 819,246Mhz, suddenly ATI have a GPU to play Crysis on high Heres the proper screenshots: With 8.6 ATI drivers (no overclocking)... And heres the actual screenshot with GPU-Z v0.2.7, then ATI CCC v8.9 (CCC shows the right speeds) Also notice the bandwidth is wrong at 64Gb/s instead of about 140Gb/s... So does anyone know how exactly this effects the GPU-Z's tool to read the speeds & was this change worthwhile for better speeds or improved technology support? And, does ATI not give you guys access to their technical support to make you aware of any unusual code changes so you don't have to play "find the pin a haystack"?
