To test ATI cards, we used the most recent WHQL Catalyst 5.4 drivers, and for the AE6800 APOGEE - beta drivers ForceWare 76.50.
Overclocking
Note that in terms of overclocking this card left quite pleasant impressions. From the default 358MHz on the chip (which is already overclocking relative to the GPU frequency standard for this card), we were able to attain 450MHz. Remember that overclocking of the graphic processor in GeForce 6800 (NV41) also amounted to 450MHz. That is, we arrive at a conclusion that the overclocking capability of NV41 and NV42 does not differ much. Actually, having tested a specimen of each of these cards, it would not be quite correct to make any global conclusions, but anyway first tests have been done and we'll deduce the statistics once a couple of specimen cards on the base of NV42 have been to out test lab.
What pleased us most is the overclocking of video memory. The 2.5 ns memory faster than that on the regular GeForce 6800 PCI-E (2.8 ns by default) allowed us to overclock from 660MHz DDR to 850(!)MHz DDR. That is, the memory overclocked by 50 MHz higher than its rated value (800MHz DDR).
Remember that tests were run on an open test bench without using additional blowing of cards or other modifications of the cooling systems (which would be some sort of blasphemy because the manufacturer installed not a poor propeller but an impressive Arctic Cooling). Only the thermo interface has been replaced (with "Alsyl-3"), and the ambient temperature in the test lab was 25 degrees.
