ATI's Catalyst 3.8 Drivers: ATI Sanctioned Overclocking

Catalyst 3.8 Drivers
The first new tab on the drivers that jumped out at us was OVERDRIVE(tm). Clicking there we see one lonely checkbox and a description of the functionality. The description states that overdrive will allow the chip to maintain its optimum speed based on the temperature of the chip.
All of the tests in this article have been done with overdrive on.
The second tab we didn't recognize was the VPU Recovery tab. In moving to this panel, we see that ATI has added functionality to their driver that will reset the video card if the hardware stops responding to the drivers commands.
This seems like a good idea as we found a problem with the 3.7 Cats where changing the D3D or OGL settings in the driver while using a DVI connection would drop the screen. I quickly learned the windows shortcut to sleep mode in order to fix that problem, but hopefully this will be a more elegant solution. There may be some overhead and there may not be, but that is a study we will save for later. For now, we left the option set to its default ON state

From a technical / technological aspect I find the Overdrive technology very interesting.I equate it to my background in automobile tuning. Carburated engines had a set timing. You set that timing sso the car would not knock and ping. Electronically controlled fuel injection allowed using different timing / fueling at different load point to extract the most from the engine. Same engine could maybe get 10% more power. Now you see very detailed EFI, where the engine computer advances and retards timing dynamically depending on octane, load and many other inputs, always giving near maximum possible output.
I see this as the beginning of the same trend in graphics cards. It makes sense.

This review was done with stock cooling. Those cards get hot real fast.Since Overdrive stops overclocking when it gets too hot, I would have like to see some form of ultra cooling on some cards like (at least) water-cooling.
The way I see it, Overdrive it pointless.

How long before we can buy a XT watercooled out of the box? I think that's the question remaining now.Anonymous User - Saturday, October 11, 2003 - link

why i cannot run halo i have a radeon 9000Anonymous User - Friday, October 10, 2003 - link
52 - That is exactly what Anand did. They ran a benchmark - recorded the results - then ran another benchmark, and so on. That sounds like they did let it cool every 10 minutes or so. Unlike a real user.50 is partially right. The bus speed improvement when OC is enabled would give much better indication of what the XT is doing over some statistically ambivalent fps count.

The HL2 stolen code setback seems to be perfect timing. Nivida has to be loving it, the bastards!The only good Dx9 game that should have been out with the Radeon XT would have put a nail in Nvidia.
Now Nvidia has breathing room. Lets see if they squander it.
Right now the clear winner for Dx9 is the ATI XT. That is if you are comparing the XT to the 5900 and not some vapour hardware.
You made the charts, take a look at them. ATI is clearly better at DX9 PS2.0. All the new DX9 games are not going to run better on Nvidia. The benchmarks for HL2 were already shown.
I don't see why you can't recommend a card at this time?
If you had 10,000 to bet which card would you pick to be the best dx9 card? If you bet on Nvidia your gonna be 10,000 poorer.

I agree, its much better than the last review. Thanks for the Fps in Tomraider.Do you know what the cap is for the XTs auto overclocking?
Wonder what it would do if you put water cooling on the ATI?
