FB-DIMMs finally arrive - Hotter with a need for synch@ 2006/05/24
This is coupled with the need to run the memory in sync with the FSB. If you run it asynch, you lose enough performance so a FBD/667 on a 1066FSB gets you negligible performance increases. FBD/533 on a 1333FSB hits you for more than the decreased ram speed too, a real lose/lose situation. So, what does this mean? On Bensley, you really want to run FBD/533, and on Woody, you really want to run FBD/667. Anything less is asking for pain.
