How to fix different programs reporting different GPU clocks

[Reaper 392]

Initially CPU-z was reporting that my new GTX 970 was running at 540Mhz core when running an old version of furmark bench test on the computer. Booting up MSI afterburner to find out why lead me to find that I was running such an old version that it didn't know what a 970 was, so the old version uninstalled and the latest version (4.1.0) was reinstalled. After that, the latest version of CPUz was installed.

Now when the old furmark bench test, both furmark and CPUz still report the core as 540Mhz, but MSI afterburner appears to report the correct clock of around 1200-1400Mhz.

Is there any way I can check to see if it is the program failing to read the clock properly or if it is the GPU misbehaving? just running a game wont really help because, having come from a GTX 460, this new card would probably be significantly faster than what I'm used to anyway

You sure they're not just reporting the idle core speed on desktop?

Yeah I'm sure. The core speed was set to current in CPUz and furmark was running at ~70FPS and had been for a few minutes. CPUz was reporting 540Mhz at the same time as MSI afterburner reporting ~1300Mhz. When the GPU is idling CPUz's reported clock drops a bit (I forget what to though)

Now when the old furmark bench test,

Thanks. downloaded 1.14.1 before I noticed 1.15.1 and that is now reporting the correct core clock as well. I didn't even realised furmark needed to be updated to properly support different GPUs. With furmark and afterburner now showing the correct clock i suspect the card is working fine and it is just CPUz thats displaying things wrong.

Ps. I assume the memory is showing up as 3505Mhz, rather than 7000Mhz, because it is double data rate which means 3500Mhz is effectively 7000Mhz
