AgaBooga told me that when doing memory intensive things, the RAM MHz speed should equal the FSB speed of the CPU. Would it be ok to use DDR SDRAM PC3200 400 MHz in a dual channel configuration? An Intel worker over the phone on Customer sales support told me that this was the optimal performance configuration and said that with Dual channel, that the memory throughput would be doubled and therefore equal the FSB throughput? Is this true? Would this be just as good of performance for everything you do as it would be if the MHz RAM speed and FSB speed matched exactly from each individual DIMM of RAM?

That is the currently only way of reaching a FSB speed of 800mhz so we don't have anything to compare 'as good of performance for everything you do as'

How is what I said a flame? I said almost the same thing in the thread you linked to... lol

Calm down dude, I didn't even mention your name. There were a lot of trash posts in that thread, but lots of good info too, just didn't want to have him get scared off by a little name calling and what-not.

I'm calm, but I'm glad you weren't saying it was me flaming. Sorry :)

Dual channel DDR400 has a theoretical bandwidth of 6.4Gb/s

While the Bandwidth between the CPU+NB is also theoreticaly 6.4Gb/s, so the Intel guy was right!

BTW you hardly ever reach theoretical bandwidth, i get 1438Mb/s WRITE and 4468Mb/s READ with Aida32 Mem Bench.

But thats running a little overclock ~10Mhz more DDR420! :beer:
