Overclocking the MSI NX7600GT-VT2D256E
The NX7600GT-VT2D256E comes equipped to utilize MSI's DOT Express overclocking which is enabled by installing the drivers on the CD, or MSI's web site. In our test scenario, however, we opted to use the most current NVIDIA reference drivers to ensure that both cards were as current as possible. So, we used Coolbits to overclock the NX7600GT-VT2D256E and our results were none too shabby. We managed to increase the GPU speed by 23MHz, which equates to 5.5%. Memory speed also increased nicely, adding 55MHz (110MHz DDR), which equals an increase of 7.33%. Next, we put these increases to the test with F.E.A.R.'s built in performance test.
To look at these results, you might think that we didn't gain much. However, with further analysis, we saw something interesting. First, with the No AA tests, we measured an increase of 3FPS, which equals 7.33%, the same increase we saw with the memory overclocking. Next, when we ran the 4XAA and 16X Aniso test, we measured an increase of 1FPS, which interestingly enough, equals 5%, very close to the 5.5% increase we reported in GPU speed. Regardless what you make of this, the overclocking of the NX7600GT-VT2D256E does result in measurable performance gains.
