ok i just got a geforce 2 a few days ago and its great for $100 but i still have frame rate probs with the pregame shows in nhl2002 and the comanche 4 demo gets a little choppy if theres too much going on at once so i'm wondering how to overclock it and if i would need to buy a new fan to overclock it.

its an xtasy geforce2 mx 400,64mb ram clock at 166mhz,200mhz processor,ramdac (whatever that is.?) 350mhz (wanted the verto cause it had some extra stuff but they were sold out).

my pc is a gateway celeron 733mhz with 320mb of ram and everything but the ram and 3d card is factory installed.


also i downloaded the det. drivers from nivdia drivers 21.83 and was wondering if updating to 21.88 would boost speed at all and does 21.88 have any bugs?

What make of GeF2?

I run a Hercules MX400 64Meg, and can clock it to 195/385 with no problems, after adding a small fan to the heatsink on the core.

Use nVtweak to access the clock frequency tab in your display properties. They are good cards for the price, but try reducing the colour to 16 bit, to get a few more FPS out of it.........


I show no difference in 3DMark2001 between the 21.83s and the 21.88's btw.

Sounds like you have a SDRAM card as overposed to RDDs DDR RAM card. I OCed my GF 2MX to 180 GPU and 200 Ram with NO active cooling whatsoever, You'll want to download the coolbits file and use it to tweak your frequencies. Also try disabling Vsync in your driver settings, That should boost your performance quite a bit.

oh yeah the card is by visiontek and yes it is sdram.
will i know when i've overclocked it to much without killing the card?to play it safe with my specs what would be a safe speed to overclock the card?
also does anyone know what 350mhz ramdac is?

if i play games in 640x480 with this card the screen is off to the side a bit...anyone know why?

thanks:)

I didn't know people still played in 640x480:D

I belive the RAMDAC is the part of your card that creates the final picture for the monitor but I'm not 100% sure on that.

As far as OCing you'll want to raise speeds slowly step by step testing each new speed. 3D Mark is good for that. When you start getting artifacts or the picture otherwise looks funny you'll know you've gone a bit too far and want to take down the speed a bit.

RAMDAC is what converts the digital picture that your video card made into a analog picture (RAM DIGITAL TO ANALOG CONVERTER) you only need that if you dont have a LCD monitor. normal monitors use analog signals and the LCD monitors that cost like $500 use digital signals. I think that the highest speed that they have now is 375mhz RAMDAC
