Can my onboard Geforce 2 MX be overclocked at all?

If so, how fast can I get it up to? Can I get it up to GTS specs?

That would be awesome. Any way possible?

I have a ASUS A7N266-e.

I don't see why not. Install the Detonator drivers, and then enable coolbits.

How far should I try overclocking it? I don't want to fry the video card. What would you recommend? This is the first time trying to overclock my video card.

First, make sure the drivers you load are 100% stable in your games, and 3DMark.

Clock up 5 MHz. Test. Do it again. While doing this do NOT click the option to apply settings at startup. Do the GPU and memory separate.

I use 3DMark to test for stability after every 5MHz jump.

When the GPU is too high, you'll experience a hard lock in 3D games/applications. When that happens, clock it back 5 or 10 MHz and there is your limit.

When the memory is too high, you'll start experiencing flashing textures and artifacts in 3D games/applications. When you do, stop and clock it back down 5 or 10 MHz and that's your limit.

Thanks for the advice. I'm at like 190/150 I think.

Thanks again. This is enough for now. I don't know if this is much, but it's enough.

Keep in mind that as you oc the Motherboard fsb/mem, you will be increasing the memory clock of the On-Board MX. For example, most ppl seem to be able to hit 156fsb/mem clock by lowering the multiplier of their CPU on the A7N266-E, and at 156MHz for the memory, you would increase the avialable bandwidth for the GF2 MX (and the CpU for that matter) from 2.1GB/ps to 2.5GB/ps. That would give you even closer to MX performance (A regular MX has 2.6GB/ps). That's where you'll get the "meat" of the oc (ie you'll get the best performance increase by ocing memory rather than core clock). But, I can guarantee you that you won't see GTS speeds:(

The MX core is built into a motherboard chipset with many other functions and I don't think it should be the only thing tested (After all, if that chipset frys, the whole motherboard is dead). Increasing MX clock speeds does not show any improvement beyone small single digit improvements (1-3% etc) because what limits their speed in the majority of applications is the memory bus. What sucks about the MX,is that it's mem bus is multiple times slower than the real GF2, and that is why it doesn't even come close (There is no way to overclock a 128-bit SDRAM bus to GTS speed of 256bit DDR). What sucks about the nForce MX, is that it doesn't even hav it's own memory bus! It uses your MUCH slower system memory (Making it slower than the average MX), meaning any significant overclock would involve overclocking the rest of your system (Memory, CPU, etc). Simply, I wouldn't do it unless I was overclocking my CPU anyway.
