Memory FSB question

Ok I have 768 PC2100(I need an upgrade bad heh) set at 2-2-2-6 1T FSB@ 266 in the bios, and i can't set the ratio myself.

When I run CPUz in windows and look at the memory, it lists everything as it is set in the bios:
133x2 (266)
FSB: DRAM 66Mhz
...thats all fine.

Then when I run SiSoftware Sandra, run Mainboard Info and look at the memory settings, it list the ddr at:
2-2-2-6 1cmd
4-way Interleave
Speed 2x240mhz(480mhz data rate)
Multiplier 6/5x

.... Is this right? or a miscalculation?

I did testing everything ran fine( Prime95 and memtest86, 2 passes working 3 but I stopped it.)

Any info would be greatful Thanks.


*edit* 2 screenshots one of Sandra and one of CPUz

Anyone know why there is a difference in the FSB between the two progs?

Would like to if anyone else has the same problem between the two progs when overclocking their memory.
