Hi,
I have a 386 33Mhz IBM PC clone. It had 4MB RAM (4 x 1MB 80ns SIMM's). 
I added another 4MB RAM this time 70ns (again 4 x 1MB 70ns SIMM's). 
My PC now runs slower. Especially at boot, the memory check is at least 
5-6 folds slower. It is also slower under DOS and Windows.
In one of the Internet postings I had read something about different speed
SIMM's on the same motherboard causing slow down, but I do not remember what 
was the proposed solution to bring the speed to normal.

If you know the solution, could you please either post here or e-mail 
to me (I prefer e-mail).

Thanks,
Halil Ozmen		halil@ittpub.nl
