Apple may seem perfect to all of us, but every once in a while, a little gremlin creeps into your life.
We found a possible little bug in the new Mac Pro manual on installing RAM. If you have 2 chips the manual says to put them in slots 1 and 2. Apple’s Memory Slot Utility, however, contradicts that and says slots 1 and 5 are correct. The manual appears to your right.
So, the manual says one thing and the Memory Slot Utility indicates another. We’re working to confirm which is right and which is wrong, but our bets are on the Memory Slot Utility winning this combat.

The Memory Slot Utility is right. In Nehalem and Opteron, each individual CPU has it’s own memory controller, and for each CPU to access another CPU’s memory, they have to go through the HT or QPI bus, and that poses a performance penalty.
Some things never seem to change
