I say nice one again. I managed to get mine stable at 1790MHz. Not sure which stepping it is, but I haven't unlocked it yet. (10.5x170MHz) If you 'member my earlier post on this thread, I swapped out the PC2100 DDR I had with some PC2700DDR. 1754 was no problem, and still stable at 1790. Would boot @ 1821 (10.5x173MHz), but was hardly stable. Temps were good @ around 40°C. So might just be reaching the limits. Need to unlock to see if I can get higher.
