Creative Geforce Annihilator Pro DDR:

I tried overclocking the memory from the default 301.
Performance increases as expected until I hit about 320.
Then something strange happens, performance suddenly becomes worse. It
is immediately apparent in the Quake3 menu because the mouse pointer
moves very laggy. The benchmark suddenly takes twice as long to complete
and is very noticeably slower especially viewing gibs.

It is possible to continue increasing the clock up to about 370 before
artefacts start appearing, but the performance only increases slightly
and is still way below the non-overclocked state.

Then returning the clock to default levels does not reinstate the
previous performance, even after allowing time to cool. The only thing
that returns it to normal is a reboot.

So what is going on? Has anyone else seen this sort of behaviour?

Quake3 demo001
