Title: RAM Slot Sequence - Single vs Dual Channel
Post by: artbuc on April 21, 2014, 05:17:46 AM
I am totally confused! I have a HP a1600n operating on Win 7 32 bit:

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00757531&cc=us&dlc=en&lc=en#N116

Slots 1/2 are blue, slots 3/4 are black. Right now I have two 512 PC-2 5300 sticks in slots 1 and 2. I am purchasing two 1MB PC-2 5300 sticks. 

1. Shouldn't my two existing 512 sticks be in slots 1/3 or 2/4 to get dual vs single channel performance?

2. How should I arrange the new sticks?

From what I have read on HP forums, the higher density sticks should always be in the blue slots. Not sure if higher density means higher RAM.

Scratch that first post. I just realized CPU-Z shows my PC is operating in dual channel. When I get the new 1GB sticks, I will put them in the blue slots and move the existing 512MB into the black slots.

There ya go...
Different MBoard manuf. do it different ways...
So for example on one manuf. dual channel may be slots 1 and 3...and 2 and 4...whereas on yours it is 1 and 2 ...and 3 and 4.

Thanks Patio. I have been looking but can not find a definitive answer...maybe it does not make any difference; but, do you know if the 1 GB sticks should go in the blue channel and the lesser RAM 512MB sticks should go in the black channel?

Thanks. Considered it done. Sticks should be here by Friday. Hopefully new video card will arrive about the same time so I can install both at the same time.
