I have been following a discussion in the MS Windows group regarding a performance degradation which seems to be traced to having memory in an expansion card. My system is a 33 Mhz 386 which has 4Meg on the motherboard and has the option to drop and additional 12 Meg in a 32 bit expansion card. My question is will the memory in the expansion card suffer from a slower access time than the motherboard memory? Email replies are fine. -Joe -- =-=-=-=-=-=-=-=-=-=-=-=-= \ \_ _/ / =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | Joe Burkley | O_O | "It's not enough that I succeed, | | burkley@cod.nosc.mil \/_\/ everyone else must fail." | =-=-=-=-=-=-=-=-=-=-=-=-=-=- \_/ -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

This speed degradation is linked to memory on ISA (16-bit) or 8-bit slot expansion boards. The 32-bit memory expansion slot does not have this problem, since it is a full 32-bit buss running at full memory buss speed. (Actually, it is an extension of the on-board memory buss in most cases.) So, no, memory on the 32 bit expansion card will not degrade system performance. -- Daniel A.
