Overclocking


Overclocking on the nVidia cards was performed using Rivatuner Release 2. Overclocking on the HD 2900 XT was performed using the AMD GPU Overclocking Tool. Again note that I am only using 2 x 6 PIN PCI-e power dongles and not a 6 PIN and an 8 PIN PCI-e power dongle as advised by AMD/ATI.

A test run of 3DMark06 was performed after the overclock to verify stability and also if the OC was worth the time.

Note that no hard or soft mods were performed on the card apart from setting the higher clocks.

Results

Here's how the cards stacked up as far as overclocking was concerned:

The Ultra did not seem to quite have the "give" in it that the GTX did and I started getting tearing, glitches and freeze-ups when I pushed any further.

Still, an OC of 680/2300 for the 8800 Ultra wasn't too shabby.

I ran a quick 3DMark06 to see how the overclock went and what the advantages were.

A healthy increase of 400 3DMarks or so shows that a small OC goes a decent way.

Mr. Smith
Nice write up.

I thought the Ultra's had a tonne of OC headroom... Evidently not.

Not free game with a £400 card? C'mon.

Looking at the OC results, budget or not, get a GTX and OC it - nothing that hasn't been said before. With the money saved get a better CPU or more RAM.

I want a GTX...

Edit: LOL - I think ilk is a very English word Quote

I found the Ultra got better scores than the GTX across the board - mainly due to those stream processors mefinksQuote
