IMPROVED MEMORY CONTROLLER
the memory controler is on die with the 64's how could a chipset improve that?
Jswjimmy; I've already thanked you for corrected my error in suggesting the memory controller is a part of the nf4 chip when it is integrated into the A64.
HOWEVER, there
IS a memory "issue" concerning the nf3 chips that was corrected in the nf
4 chips. This "issue" concerns the problems using certain memory configurations and DIMM placements in the four DIMM slots on nf mobos.
For nf3 and earlier mobos if one were to populate DIMM slots 1 and 3 with TWO DOUBLE-SIDED PC3200 dimms or ALL FOUR DIMM slots with FOUR DOUBLE-SIDED PC-3200 dimms then the nfx chip would LOWER the memory bus from 400MHz effective to 333MHz effective and default from 1T to 2T.
The nf4 ALMOST fully corrects this issue. If the two same scenarios described above are implemented on an nf4 board, the PC3200 memory will run at the
proper effective
400MHz speed but will default from 1T to 2T (assuming your memory can even run at a 1T setting).
It was "this issue" that caused me to mention in the earlier post that the nf4 has an improved "memory controller".
