Well, I ran the old version of the C6 with 180 Mhz in an crappy PCChips-Board 3 months under Windoze NTwithout any probs The chips should have been certified also under several Unices for operation. Also the Asus board is know for some stability, I also put together some boxes with that board. Thermal issues are non-important (at least the old Winchip was able to run 2*50 MHZ=100 MHz) without any cooler without probs... It is imaginable that some power-saving code in -current does not work properly with the IDTs Or that the bus speed is too high and out of spec. (some series needed to do 75*3, like Cyrix) Possibly other problem could be the 1st level cache, which is a bit bigger and different organized than that from a Intel chip. Regards Olaf Hoyer P.S.
