hi All
I ran into a similar with AMD K6 series processors, I found that between 64 to 128
MB was noticeably faster than 256 MB or more, now i am running a PIII a T-Bird, a
Duron and a Classic Athlon and have not noticed the same correlation, i am running
at least 256 in all of them. When i had a PII it also did not seem to have the same
effect. I am not familiar with Dell model #s so have no Idea what the configuration
might be, but on the T-Bird it seems to go slightly faster by using cas 2 ram as
opposed to cas 3. I run both the cmd line version for NT and the linux one so don't
know if that will help or not, but good luck.
I can't hurt to check the memory configuration in Bios and make sure that the new is
at least as fast as the old e.g. pc133 cas2 is faster than pc133 cas 3...
Good luck.
