Your memory is not running on DC

Depends on your motherboard, it might or it might not support it.

maroon1 · 05-20-2006, 01:56 PM

memory channel A slot 0 512mb (DDR400)
memory channel A slot 1 not installed

memory channel B slot 0 512 mb (DDR400)
memory channel B slot 1 not installed

my mother board is intel 865PERL

it says on the bios that my memory speed is 400mhz not 200mhz, so is it running on dual channel ?

EDIT: and is there a program that can detect if my memory is runnig on dual chanel, because i want to make sure that iam running on dual channel 100%

CPU-z will tell you. google it and download it.

DDR400 runs at 400MHz effective, 2x200MHz.

Dual channel changes the width of the data channels, which are 64-bit, into 128-bit. It doesn't change the clock speeds.

EDIT:
I'm a bit fuzzy on the details of how Dual Channel really works. I made a picture of an explanation I once read.

now is my memory running on daul channel?

Yes it is running dual channel. For dual channel to work on that board you need to have same sized DIMMs (which you do) in channal A and channel B in the same slot number (ie A0, B0 or A1, B1).

In that cpu-z screenshot, it even said it was running in dual.
