GPU-Z discrepency with CCC - 7970

[Genny]

GPU-Z is 0.5.9
Catalyst version 11.12

Picked up an Asus 7970 (reference card) the other night and wanted to do a mild overclock while I wait for my waterblock. Essentially, when I up the clock speeds using CCC, GPU-Z will report the change on the 'graphics card' tab, but on the 'sensors' tab, the core and memory speeds never pass default settings. Not sure if GPU-Z simply isn't recognizing the change accurately, or if the overclocked settings aren't sticking for some reason. The above readings were taken using furmark as well as a 10 minute session of Skyrim...clocks stuck at 925/1375 in GPU-Z.

Voltages are stock aside from setting power control settings to +20%

I think CCC failed to register the overclock u have set

Try MSI AB and tell us if u will have the same issue when oc'ing there.

Strange...same deal with MSI Afterburner. It acknowledges the changed clock speeds but under stress, the senors reflect default speeds. Setting the speeds in afterburner also does nothing.

edit: rebooting and trying again with afterburner seems to have done the trick.

Thanks Kaynar.


second edit: Think I'm gonna have to take this thing back. Even at bone stock speeds while just browsing the web, every so often I'll get a quick flash of red squiggly artifacts on the screen. It also seems that VDDC is spiking to 1.498v and a low of 0.500v without any manual changes to voltage.
