OK, here's how I got this motherboard to accept AMD K6 processors with Vcore voltage of 2.2V.
This modification doesn't come without risk. I've noticed the votage regulator gets VERY HOT. As a result, I don't know how reliable this modification will be. Therefore, if you try it, it's at your own risk.
1. First, you need to make a jumper with a resistance of 25 to 40 Ohms. 40 Ohms will result in 2.17V, and 25 Ohms will result in 2.27V. This jumper is placed across JP12. This effectivly drops the 2.5V default of this jumper setting down to a value the K6 can use. See the 25 Ohms (10 + 15 Ohm, .5 Watt) resistor used in the following illustration.
2. To use the higher multiplier settings the K6 will require, you'll need to make a long grounding jumper for pin W-35 of your CPU. This pin when grounded allows for multipliers 4X and higher.
| JP13 | Clock Multiplier W/Pin W-35 Grounded |
| 1-2, 3-4 | 4.5X |
| 3-4 | 5X |
| 1-2 | 4X |
| 5.5X |
I soldered the long jumper to CPU pin W-35 on the back of the board.
From here it's just a matter of finding a grounding pin to use. You can use the one I used here, or the one identified for your CPU fan. (Note: The pin that has been jumpered has been marked for reference.)
Once the modifications have been made, the board should boot up fine. The BIOS of course will not correctly identify the CPU but the system will still work at it's proper speed.
If you have any questions or suggestions, please drop me a line:
