Predictably enough, the card we got overclocked well. It would be pretty sad to have this cool looking card that has a Blue Orb HSF and copper heatsinks just to run it at spec, after all. The card already comes clocked higher than the reference speed of 200/460, shipping at 215/515. But given the fact that it uses 3.8ns DDR RAM, it was clear that the RAM had some room to go up; and the cooling on this card made it apparent that we should be able to get it even higher than we could otherwise.

While it should be noted, at this point, that your mileage may vary and that, particularly with a smaller company, the card you get and the one we got sent for evaluation purposes may differ slightly, I was able to run the card without any erratic behavior at 240/555. At higher clock and memory speeds, some applications began displaying some irregularities that made it impossible to call stable. But at a 240MHz clock speed and 555MHz memory speed, I had no problems running Quake 3, 3DMark 2001, Aquamark, Vulpine GLMark, and Max Payne. And performance, of course, went up with the speeds, particularly on higher-resolution tests.

Card	1024x768	1280x1024	1600x1200
OCZ Titan 3 @ 240/555	178.4	133.6	94
OCZ Titan 3 @ 215/515	171.8	121.3	85.1

That Leadtek GF3 card I used in the earlier benchmarks has now been taken out of the running because while getting it to the OCZ Titan 3's default of 215/515 was no problem, getting it up to the 240/555 we overclocked the Titan 3 to proved impossible.

As you can see from these Quake 3 Arena scores, moving from 215/515 resulted in a 10% speed increase at 1600x1200, both at 16-bit and 32-bit. Low-resolution scores (640x480 and 800x600) did dip slightly, but I doubt anyone needs a game to run faster than 192 frames per second at 640x480.

Card	Aquamark	GLMark
OCZ Titan 3 @ 240/550	23.6	30.6
OCZ Titan 3 @ 215/515	21.6	30.1

Card	Score
OCZ Titan 3 @ 240/550	6400
OCZ Titan 3 @ 215/515	6043

And as you'll see here, both Aquamark and Vulpine GLMark showed only negligible speed increases from overclocking to 240/555; but the 3DMark 2001 score we got is the highest we've seen from a GeForce 3, with its 6400 score we got 6% faster than at the default clock and memory speeds of the OCZ Titan 3 and 12% faster than what you could expect from a reference GF3 at its default 200/460 speed.
