We've swapped out the DIMMs on MegaRAID controllers.  Given the cost
of a standard low-end DIMM these days (which is what the LSI
controllers use last I checked), it is a very cheap upgrade.

Admittedly I've never actually run benchmarks to see if it made a
significant difference in practice, but it certainly seems like it
should in theory and the upgrade cost is below the noise floor for
most database servers.
