Hi!
My rig is as follows:
i5-3570k
Sapphire R9 290 reference
8GB ram
Windows 8.1 Pro
When I use GPU-Z my GPU starts throttling frequently (see the pictures).
Resulting this (white lines of the core and memory clocks are the throttles):

The exact moment of a throttle:

This doesn't happen, if I don't execute GPU-Z.
Before anyone says that this is temperature related, it is not. As my temperatures were (76-80°C) far inferior to my temperature target (88°C) and with out GPU-Z I don't experience the throttling.
This can be reproduced easily by just executing GPU-Z 0.7.5. when ever I'm stressing the GPU.
The throttling occurs even when down clocked (for example to 700MHz) and drops the core down to 300MHz causing fps drops etc.
