Overclocking Limits:

For GF2 MX400 Series: 200~240Core, 200~230Memory.
For GF2 Ti Series : 280~300Core, 450~530Memory.
For GF3 Ti200 Series : 220~240Core, 450~500Memory.
For GF4 440-MX Series: 290~320Core, 450(5ns ram)~520(4ns ram)
Memory.

Here are some programs you can use to determine the limits of your card. If the display goes crazy, restart PC and backdown the clock a bit.

Note: If you see white dots on the screen then it's a memory problem. If you see the figures have odd shapes then it's a core problem.

Suggested Settings:
When overclocking your video card, it is suggested that one uses 2X AGP transfer, disable Side Band Addressing (SBA) and AGP Fast Write.

Some Overclocking Tips

1. Disable APG4X, Sideband addressing, and fast write, if u can. This will generally give you another 5~10MHz.

2. Increase the I/O to 3.5V or 3.6 as it normally increase the voltage the video ram is getting(for GF2MX) which is good for oc. The higher priced GF2, GF3 and GF4 have another voltage controller for ram.

3. Add an active cooling for your VGA card, reapply the thermal component as manufactures are very slack at this.

4. Do not increase your core and memory at the same time. Leave the core at its original frequency and increase the memory's frequency to the max. After reached the max for your ram, increase the core.

5. Add a ram sink after u go beyond 500MHz (DDR clock)

6. Flush your VGA Bios, it may increase the range u can oc.

7. Play around with AGP driving control. It might increase your range of oc.

8. Try out different drivers, some offered better oc ability.

9. Install the latest VIA AGP patch.

http://www.driverheaven.net has some great drivers and help for overclocking ATI Radeons, nVidia and Matrox Parhelia cards. If you have a radeon then use the Omega drivers as they will improve performance massively.
