As the title says ... I have tried GPU-Z versions from 5.6* back to 4.4. Running CCC 11.9 due to incompatability with a BOINC project for later versions up to and including 11.11*. Board:- Asrock A330 GPU:- HD2400 PCI (not PXIx/PCI-e) RV610 OS:- Windows 7 Pro SP1 64-bit Weirdly, ATI Tray Tools (184.108.40.2063) works and even allows me to overclock ever so slightly although no temperature info is available. * this combination allowed GPU-Z to work but is incompatabe as above therefore cannot be used. Context:- I need GPU-Z to work on this PC as it is destined to be used as a headless server monitored remotely therefore I need as much hardware info as possible especially GPU load & temperature ... which is where GPU-Z is the best tool that I have found for the job. Help!
