|I'm not sure you're understanding how things work.|
PC2100 is designed to run at 133MHz. You *may* be able to get it to run a little faster by playing with the settings & increasing the RAM voltage, but you will NOT get it to run at 200MHz or even 166MHz for that matter. Just run the CPU at it's default clock speed of 2.2GHz at 11 x 200MHz & run the RAM at it's default speed of 133MHz. Sure, performance will suffer, but you really don't have any other choice - you have the wrong RAM!
On the motherboard, set both the CLK_SW & CLK_RATIO to AUTO.
Here's your BIOS settings:
System Performance = Manual
FSB Frequency = 200MHz
Memory Frequency = By SPD
AGP Frequency = 67MHz
That's it! There's no point in doing it any differently as long as you have PC2100 RAM.
BTW, here's your motherboard manual:
