CL2.5 errors but 2.0 wont???

P4C 2.6
ATI Radeon 9800 non-pro
TwinMOS pc3200 BH5 chips 2x256

Here is what is wierd. I can run prime 95 stable 24 hours @245fsb 5/4 divider 5,2,2,2.0

However... if I try to run @CL2.5... I error out? Doesnt this seem a bit odd?

I wouldn't care too much, run CL2

btw, Twinmos still sells BH5 sticks?
