High HTT/FSB on divider tests.

Seems so far managed 366FSB/HTT as the highest i've been able to boot into windows. It needed LDT dropped from 4x to 3x though. Managed to push out an 8M time but windows frooze trying to save the cpuz validation file heh.

But seems 334FSB/HTT is fine with LDT 4x!. Haven't tried higher than 334FSB/HTT for now.

Click on image for large full size screenie with A64Info showing the HTT Bus speed etc
