I have an M Technology R528WP mainboard. The manual states that it can support a Pentium 200 MHz MMX chip. I installed a Pentium 200 MMX processor, reconfigured the board for split voltage, system clock (66MHz), frequency ratio (3/1) and refresh time to support the 200 MMX chip. I used the manual that came with the board as well as went to the M tech web site for a manual update. I went over the settings numerous times, especially the frequency ratio and I cannot get the frequency ratio above 2.5 times or 166 MHz clock speed.

I checked the processor part number (SL27J) against the Intel listing and it is rated with a core frequency of 200 MHz. So I believe the chip is capable of running at 200 MHz.

I have used system information software such as “Sandra” and the software reports a frequency ratio of 2.5, not 3.

I flashed the Award BIOS. The original BIOS had a version Cu and now it has a Hu and recognizes the MMX chip. Do I need to clear the CMOS after I flash the BIOS?

I contacted SOYO and the technican explained that some early R528 boards had a problem. The fix was to solder a 1k ohm resistor across two points on the back of the motherboard. They faxed me information with a clear discription. I'm quite skilled at performing the task and now the 200 MMX runs at its intended speed.
