DDR2 arrangement

[evildragon]

Ok, on my new IBM ThinkCentre, it has FOUR DDR2 slots, one of them are factory filled..

It goes like this.

(Top)
DIMM 1 - BLUE - 512MB
DIMM 2 - BLUE - EMPTY
DIMM 3 - WHITE - EMPTY
DIMM 4 - WHITE - EMPTY

What I'll do is get a matching 512MB stick (brand, size, and speed), but which slot do I put it in for Dual Channel? Slot 2 or 3?

Why not get the docs from IBM?

Thank you very much, much appreciated.

Because the docs suck and don't mention anything about the colored banks?

When in doubt, Google and Wiki:

http://en.wikipedia.org/wiki/Dual-channel_architecture

But you have your answer already ..

The Wiki conflicts what JDT said though.

From my understanding, I'm supposed to match colors, so both 512MB's should go in the blue, but then Channel 3 is WHITE, not BLUE.

DDR is confusing to me, HENCE asking.

Nobody criticized you for asking. Take a breath and calm down.

If the Wiki conflicts with something else, then it's time to do more reading.

I'm done reading and researching, I'm tired... If you know the answer, just spill it please...

evildragon,

I have a GigaByte Triton MB, with 2 each blue and white ram slots. According to the manual, you should have 2 sticks in the same colored slot to be able to use dual-channel ram (double memory bandwidth).

So, a pair of 512MB sticks in the blue slots will give a total of 1024MB ram with dual-channel capability. This is, in fact, the way my board is set up.

I don't know about DDR2 but you couldn't go wrong with the old DDR. If you put the 2nd stick in the wrong slot, you still got your 1 Gig of RAM but it only worked in Single Channel mode AFAIK, DDR2 works in pairs so you can't go wrong (much). I don't think you can fry anything by putting the 2nd stick in the wrong bank. It's been like this since forever

Yea, I want the dual channel, not single channel.

I got the answers I needed, thanks all those that helped!
