View Full Version : What type of memory for typical 286 or 386 motherboard?

I have a typical 286 and 386 motherboard. Does anybody know typically what memory is used? What I mean by this is whether it needs to be parity or non-parity. Thanks.

That's a pretty broad question. I have 286 and 386 boards that take DIPs (of various sizes), SIPPs (mostly 30-pin) and SIMMs (mostly 30-pin). Precisely what do you have?

Most generic boards that took SIMMs didn't care if the memory had a parity bit or not--some allowed you to explicitly disable parity checking. Something I've seen on both 30 and 72-pin SIMMs is a "cheat"--a parity generator chip rather than an extra bit of DRAM. Absent spilling coffee into the works, it's therefore impossible to get a parity error, even if the data's wrong.
