- When you say 18 -- a assume you mean 2 SIMM or SIPPs, where each
- SIMM/PP have 9 chips. In other words you have 2 1Mb SIMM/PPs and
- would like to add 2 256K SIMM/PPs.
-
- The answer is NO. You cannot mix different SIMM/PP memory size in
- the same bank, one bank being 4 SIMM/PP.
-
- Please note that the issue here is not mixing 70ns and 100ns DRAMs.
