Welcome to the forums!

What version of XMS3200 do you have?

The older v1.1 sticks use the Winbond BH5 memory chips and overclock pretty good for what was a first-generation low-latency DDR400 chip. (Long way of saying the newer PC3500+ memory overclocks from the default PC3200 speed better than the v1.1)

But the later versions of XMS3200 used BH6 chips and they sometimes had problems running at the stock speed on 875P boards, regardless of how loose the timings were. A lot of people who bought XMS in anticipation of how well it worked on 845 boards had a bad surprise when the Canterwood and Springdales came out.

Check your heatspreader for a sticker showing the revision of the memory. If it's anything but v1.1 you're going to have a hard go getting that memory above 200MHz.
