- Some motherboards (and they tend to be the more poorly designed ones)
- are particularly sensitive to RAM and balk when using mismatched
- banks.
-
- At present, however, I am using a no name clone motherboard with four
- 80 ns 3-chip SIMMs and four 70 ns 9-chip SIMMs -- and it all works
- just fine. And that will be the rule rather than the exception.
- However, in those cases where you get numerous TRAP 2 messages,
- suspect mismatched RAM, particularly a mixture of 3-chip and 9-chip
- SIMMs.
-
- Due to some recent experience one should also suspect the RAM cache.
- Some vendors, it seems, cut corners and supply slightly out of spec
- cache memory, substituting cache that is too slow for the system.
- This, too, can result in memory parity errors.
