Installation / Setup Of The GeForce2 MX
Classic GeForce but begging for some "tweaking"
 
Behold the GeForce2 MX in all its frugality....


We don't need to go into a lot of detail on the installation process for you.  It was all very uneventful, just the way we like it.  Pop the card in, install the drivers, you know  the drill.  Here is a shot of the control panel for the NV11 currently.  However we are told this will change soon with a driver update.

We then installed the "CoolBits" registry tweak (download link) to access the over-clocking control panel.  You knew we were going to over-clock this bad boy, right? 

Overclocking The GeForce2MX
A little tweak here and a little there...

The board we received directly from NVidia, as you can see in the above shot,  was minus the heat sink and fan combo we are use to seeing on GeForce and TNT boards of the past.  This is a testament to the MX's excellent power "sipping" architecture.  The chip actually gets warm but not hot to the touch when clocked to the stock 175MHz. speed.  However, we were able to overclock the chip to 195MHz. Core and 210MHz. Memory clocks, right out of the box.  That brought us to the next step in tweaking the MX.  We pulled a heatsink off of a Leadtek Winfast GeForce 1 card and plugged it into the already prepared push-pin holes on the GF2MX board.  Here is the result of that effort.

As you will note in this picture, the active heat-sink/fan assembly doesn't have a site on the reference board to plug its power connector into.  This is easily remedied by hooking up a three pin male power header on the end of a pig tail power splice, as shown here.

All you need to do is just plug the two black and red pins into the corresponding mates on the fan connector and your are in business.  Now, all of this will be a non-issue should you pick up a retail version of the GF2MX that has a heat-sink and fan on it, although we are sure that there will be many that don't due to cost constraints.  Regardless, this is a quick and easy mod that you can do yourself without much trouble.  Just remember to apply a nice thin coat of thermal grease or paste on the backside of the sink and you'll have an excellent cooling solution.  We could have looked around for larger sinks that fit of course but this was such an easy "bolt-on" solution that we just went with it. Here are the results again of our minimal efforts.

This is a decent gain for such a quick modification.  Also, as a side note, the memory clock was pegged at 210MHz. which was as far as it would go with the slider.  However, we get the distinct impression that it could go even higher with stability.  The core clock made it to 205 without artifacts, popping pixels or a lock-up of any kind.

So, let's take a look at the numbers, shall we?
