Looking for this Asus TXP4-X mainboard. I is old clunker, but when flashed with bios from Asus TX97-XE and wrongly switched (undocumented switch), it give 7.14MHz FSB.
That turn into second lowest CPU-Z clock record that I hold for some time with this submission: http://valid.canardpc.com/show_oc.php?id=348684
But that was friend board I just recapping for him:
Now I get idea, how to get even lower with this mobo (force x1 multiplier), so if anyone find it, I would pay for it some reasonable price
