No matter your graphics card, there comes a time in your computer's life when it can no longer cope with the latest technological demands the ever so popular games impose. This is one of the main reasons for overclocking your graphics card. Gamers are always looking forward to a little extra boost in terms of framerate. Even though most of the times the boost is far from noticeable, overclocking remains the last resort when you can't afford to buy a brand new VGA card.

The default frequencies for the Aopen 7800GTX are 450MHz for the Core and 1250Mhz for the Memory. We tried to push these frequencies while maintaining valid and stable performance, finally maxing out at 499MHz for the Core and 1390MHz for the Memory, whence the tests were carried out once more. We compared the results between the default frequencies and with the OC and this is what we got.

Let's see how much of a difference in performance we achieved.

Unfortunately, in both cases (Doom3 and HL2), the difference between default and OC is no more than 4-5 fps. Note that the OC version of the 7800 (which we achieved here), is now the same as the ASUS N7800's default Core and Memory frequencies.

The OC 7800GTX reached the performance of the ASUS N7800 as it can be seen in these graphs. Even though performance did not dramatically increase in terms of fps, some improvement has been made.
