It came with the Turbo option, but I was having problems with graphics lockups, so that's sitting in an antistat bag

Not sure if IRIX 4D1-3.3.2 has a bug or something, but the machine slowed down noticeably after going from 32MB to 64MB. Guess I'll back down to 48 and see what happens.

Is it possible that RAM chips are different speed. Does one have -60 on it and one have -70 or -50 or it..?
Chips used to have how many nanosecond they were rated for marked on the chip itself..

They're all 70 or 80nS, and 4D/25 is supposed to support 80-100nS (IP12 SIMMS are 80nS). Each set of 4 is matched.
