- Some 3rd party memory that was announced for the r4k Indigo had 36x1
- SIMMs rather than 9x4. The extra chips cause extra bus loading, which
- may (and may not; it is hard to say for sure without a lot of analysis)
- cause problems. I don' know if it was from Kingston or somebody else.
- The smaller capacity chips are presumably cheaper per MB, but somewhat
- harder to fit in the same space, as well.
-
- Our hardware engineers weren't willing to commit at all to the 36x1
- SIMMs working reliably. I don't know what the vendor's 'fix' involves,
- or whether it truly fixes the problems the extra chips introduce or
- not. I don't know enough about bus design to comment from my own
- knowledge.
