Leadtek has added on-board hardware monitoring to these GeForce2 MX models which is also found on other WinFast graphics cards such as their GeForce 256 and GeForce2 GTS. To assist the user in visual troubleshooting, there are three LED lights which indicate the status of the graphics card:
- Power - a green light indicates that the graphics card is getting power and is working.
- Error - a red light indicates that the voltage the graphics card is receiving is less than 2.9 volts.
- AGP4X - a yellow light indicates that the motherboard and graphics card both support AGP4X. If the LED is off, it indicates that the motherboard does not support AGP4X or the card is unstable under AGP4X.
Here's a picture of the Leadtek PCI card in my system. The card is in the PCI slot located directly under the AGP slot which has a yellow sticker attached to it. The green LED on the graphics card is in the center of the picture and is about the size of a pinhead.
Power On LED
Note that the AGP4X indicator is not active. This is due to the overclocking of the front side bus speed (FSB) on my Abit CUSL2 motherboard which reverts back to AGP2X in this situation.
The WinFox Hardware Monitoring provides key information on the temperature and voltage of the graphics card. The sampling time can be adjusted as well a the temperature threshold which is reported in celcius or farenheit.
A test of running a looping demo of Quake 3 in a window for 30 minutes verified that the temperature settings were being recorded. After running the demo with both the core and memory speeds overclock to 200MHz, the chip edge and surface temperatures had both risen 2 degrees celcius. It would proably have been higher, but I had my case open at the time.
