Overclocking the GV-N595U Benchmarks

Due to the thermal safeguard abilities of the FX59XX series GPUs, overclocking the GV-N595U is a rather imprecise science. Instead of a linear progression of performance improvements, continuing until you push the card too far and get artifacts or lockups, the FX5950 tends to throttle itself back to protect itself when you over stress it.

This is not to say that you cannot overclock the card though; just that it requires a different kind of observation. When you would otherwise be seeing the telltale signs that you have gone too far such as artifacts, you will see nothing wrong but your benchmark scores will simply drop instead.

As usual, the Coolbits utility enables overclocking in the Nvidia control panel. In this section, you may notice an 'automatic settings' button, which will actually overclock the card for you, to a (generally slightly conservative) setting. Now I'm not sure if it's the 52.16 drivers or not, but while this button seemed to work fine if we started from the default clock settings, hitting it after manually overclocking the card resulted in some extremely high settings, high enough to lock up the card, thermal throttling or not.

Best to do things manually here then. After some playing around, we settled on 516Mhz core, 1.02Ghz memory timings as being a good stable platform to use for our overclocked benchmarks.

8. Gigabyte FX5950 Ultra (516/1020) 6089

Since the 3.4.0 version of 3Dmark 2003 came out during our testing of the card, we had a chance to benchmark with both versions. As you probably already know, the newest build of Futuremark's synthetic benchmark considerably lowers the scores that recent Nvidia cards achieve.

We saw this illustrated very clearly, as with both overclocked and stock settings, the 5950 dropped ~900 3Dmarks with the new build. Pre-patch, the 5950 actually managed to achieve an impressive 6980 3Dmarks, which dropped back to a more reasonable 6089 with the new version. At stock, the FX5950 now comes in a little behind the older ATI 9800 Pro in this benchmark, which hurts a little.
