The difference between 133 mhz sdram and 100 mhz sdram is about 1/3.
Same as a 400 or 300 mhz CPU.
The S-Spec's of your Cpu.Look them up.Would determine if you could benefit
from the 133 MHZ Sdram.
The FSB is going to determine everything.I have a Gateway.It was originally
P2 450 100 Mhz FSB.I bought a Lin Lin Adaptor and a 1000MHZ Socket 370 CPU.I upgraded from 128MB of Sdram to 512 Mhz Sdram.
My computer is by no means a gamer but,it is twice as fast as it was and it
will be 8 years old in a couple of months.
It is by no means decomposing.It operates as well as it did new.
There are people out there who will agree that the 440BX motherboard was
quite a jewel.
