mixing RAM types

[Jorge M. Pacheco]

I wonder if anyone has ever tried to mix nodes in a beowulf which use different types of RAM.
We just bought some new AMD's with PC2100 and added them to a beowulf with SDRAM/PC133.
The result is ackward, in the sense that the behaviour of the new nodes depends VERY MUCH on the settings I use for the 
DDR DIMMs.

Any experience/clue ?
