System Model : XPS 435 MT

Memory : 3x2GB of DDR3 memory with 1333MHz.

I have 2gb of 3 memory sticks - total speed shown is 1066 MHz instead of 1333 MHz

Tried populating memory in combinations of 135 & 246 , made no difference to the speed

As per Triple Channel configuration, 3 memory sticks of 2gb each , total of 6 gb on slot 135 or 246 should show 1333 MHz not 1066 MHz

Pl advise

More about triple channel memory speed difference
  1. By default X58 and i7 920 run memory at 1066mhz. You'll need to go into the BIOS and change the default memory multiplier from 2:8 to 2:10, that should equal to 133mhz x 10 = 1333mhz RAM.
  2. As for the rated speed: The SPD chip on your RAM provides a number of potential settings, and your computer's Bios has chosen the default. If you don't like that it's showing a different number, then set your memory divider appropriately. 2:10, as Flyin indicates.

    As for any difference in speed... You may not want to bother, since there is little/no performance gain associated by running higher clocks:,2325.html
