I've been runing the backside at the factory default of 222.2 Am using MachSpeed Control v. 2.6.1. The newest.

Have you tried de-interleaving? I THINK WE HAVE B-I-N-G-O! I had just evolved to this same conclusion. Yesterday morning I had removed the one remaining stick of 128 mb 'Tall Ram'. This clearly took care of the cold start monitor delay and the problems running Quicktime 6. As of this morning, I backed the cpu down one more notch, down to 445 mhz and a bus of 55.6 Mhz. Since then, I haven't had a crash all day. :) Knock on wood. Funny that a measly 3 Mhz can make such a big difference. If all goes well, my guess is, not only did I max my bus speed as one factor, but the infamous 'Tall Rams' are clearly of a slower 'nano per sec' then thought, so they were hamstringing the cpu's speed requirements. As reiterated by Harbourmaster, it is something others might consider if they are having problems. (John Hobbs have you looked into this possibility for your 360Mhz limitation with the 450 Formac?) While its still too early to tell, I'll bet if things remain stable from here on out, I won't be able to put the Tall Ram back in without causing instability again. In fact, after a few days of stable running at 445Mhz, I may just try this to be certain. When my first stick of Tall Ram went bad over a month ago, symptoms were obvious during cold start. It failed miserably during various Software Memory Tests too. This second Tall Ram I have however doesn't even raise a red flag on any of the tests, but clearly it is problematic. In fact it is probably just fine for a slower processor as it was with my 300Mhz. Dan_A, you have a couple of Tall Rams in your machine, if you are running a G3 over say 400-450, are you having any similar symptoms? Anyway, I'll give it through tomorrow to be certain but I think this may do it. Thanks, Dave -- SuperMacs is sponsored by <http://lowendmac.com/> and...
