wasn't trying to pick a fight or anything..
my understanding is that when you run pc100 in a 133 bus, you are, in effect, overclocking the memory and that can cause issues.
I run pc133 in my 100 mhz bus... (i.e. the reverse of the above situation - "underclocking" my ram, if you will)
as I said, it was a wild guess. I was only tryin' to help, don't get all upset on me here
