- Are there any 486 motherboards that use (PS/2 ?) 36-bit memory modules ?
-
- I'm looking for ways to replace or upgrade my home 386 computer to a 486
- with 16Meg of memory (for 32-bit O/S).
-
- By employing 2 banks of 9-bit SIMM's, most 486 motherboards are optimized
- for 8M of memory (or 32M). To get 16M, one must put 4M SIMM's into a single
- bank. There is no interleave, but luckily, the cache system can cover up
- the problem somewhat. Doesn't that sound stupid anyway !
-
- On the other hand, if the boards were designed for 36-bit SIMMs, four 4M
- (1Mx36) modules would yield 16M with 4-way memory interleave ! I find
- 36-bit modules more flexible and suitable for 386DX and 486. But they are
- not widely used in clone systems, why ?
-
- Theory aside, how do 16M, one-bank machines fare in real life with real
- applications ?
-
- Thanks for any information you can provide.
