Ok, let's put this simple... I purchased a boxed 300A made in Malay, I guess it's a SL2WM (OR SL2WN). I originally purchased a Diamond Micronics C400 (good board, many PCI slots, no CPU monitor, no overclocking unless B21) and 128Mb PNY-PC66 form Compusa.

I bought a DFI P2XBL Rev B+ and I did the overclocking right away. The machine have been working flawlessly. Quake 2 at 640x480 went from 51fps to 71fps with my CL Riva TNT AGP.

The board supportss clock speed from 66 to 133. The CPU configuration is done using DIP switches. There is a jumper that let you specify the FSB Speed, 2 options Default, then you can change the bus up to 83 Mhz and the other option is 100MHz, thta can be changed in BIOS from 83 to 133. It comes with the Winbond CPU monitor, so you can know what is going on inside.

The amazing things is that I'm using PNY-PC66 SDRAM. I think this was just luck.

So, I'm posting this message to let you know that I guess there's another alternative to the Abit BH6/BX6, Asus P2B and FIC VB-601.
