Sandra not reading correctly??

[H4rm]

I have an Abit KT7-Raid motherboard, 1 ghz Socket A T-bird, PC150mhz Mushkin HSDRAM, and Sparkle 300 w Pwr supply. After having run Sandra Pro on win98 and Win Millenium, my FSB reads 100 mhz? It should read 133 or 150 mhz right? I do have Host+PCIclk enabled in the Bios. Why wont Sandra read this correctly, and how do i fix this or is there another software that will give me good readings on my ram speed or FSB speed?
