Red face GeForce clock speeds...

Galaxy GeForce 670 GTX.

Binary drivers from NVIDIA.

GPU clock speed = 700Mhz

The card is factory clocked @ 1000Mhz.

It runs fine in windoze.

Apparently, starting with the Fermi cards, NVIDIA stopped supporting the Coolbits option in xorg.conf.

I am angry.

Does anyone know how to get around this? I'm being very hopeful asking that question...

Usually the driver clocks down the GPU when in desktop mode to keep it cooler and save energy. Have you tested the clockspeed under load?

Yes, I ran the heaven benchmark.

Attribute 'GPUCurrentClockFreqsString' (workstation:0.0): nvclock=705, memclock=3004
'Prefer Maximum Performance' checked in nvidia-settings.

Driver version 310.19

I never thought to research the damn overclocking on an NVIDIA card - I've been doing that since day one with NVIDIA... I probably would have bought an HD7970 had I known NVIDIA butchered such features. I can't even change the fan speed!

If its a 'factory overclock', you shouldnt need coolbits or any other overclocking software.

Either your GPU isnt under full load, or the drivers are downclocking the card, or the speeds are misreported, or there is some other issue.
