If you've got them in different coloured slots then you will only be running in single channel. If you've got them the same coloured slots then you'll get dual channel.

look in your motherboard manual and follow instructions for which slots to use depending on how many sticks of memory you have.

Usually you put one stick in he slot nearest the CPU and the other stick in the slot that matches the colour of the first slot so usually 1 and 3

not true it's just as often the 2nd nearest and the farthest.

Would that really matter provided it's in 1&3 or 2&4? Or is there a primary channel?

it would make absolutely no difference, just preference and ease. I found it easier to use 1&3 on my old mobo because my case sucks for cable management and with a Corsair TX850W power supply, that is somewhat difficult to not run a cable or 2 over the memory, so having 4 open was easier, because that was closest to where my cables ran.

But, before I had that PSU, I had an offbrand (oh I know, I was a noob back then) which had hardly any wires, and because of my now sold, rather large CPU cooler, it was easier to use 2&4

I'd agree with mame, in theory having the memory closer to the CPU makes sense, if you measured the combined length of the circuit-traces from slot 1&3 you would find them a tincy wincy bit shorter than the combined length of slot 2&4

Slot #1 is nearly always recommended by Memory tech support when people are troubleshooting and need to perform single stick testing . . . this would seem to confirm that it is the superior slot in some way! . . . may as well use it! :cool:

Lmao, the speed difference due to distance wouldn't be measurable, let alone noticed, but I think you were joking

just my 2 pence but on my current mobo it is recommended to use certain slots when OC??

evoyear · 27 Dec 2009 at 19:11

Maybe after a long time, a shorter circuit may be a good choice

all mobo manufacturers rigorously test their prdocuts, I would imagine they did their testing with 2 sticks in slots 1 and 3 when overclocking, the human brain does like order after all, and 1 and 3 is before 2 and 4.

That is the only reason I can think of, but never have I come across a mobo that won't post or BSODs or is less stable or slower when memory is in one slot over another.

I'd say you had quite a strong opinion there aastii . . .

Not sure what your clocking background is but once you get into high speed northbridge and high speed memory you may find you begin taking more notice of which memory slots you are using particulay if your need the DRAM Slew Control . . .

no no, I am quite happy to be wrong, just saying, from experience I haven't ever come across a system that has benefitted from having memory in one set of slots over another

That's fine and its always good to share your experiences with others but what I am saying is . . . . keep an open mind with this stuff, it may make no difference at all but then again it could make all the difference in the world . . . . don't limit yourself and try not to limit others by telling them it makes no difference, we are all involved in a hobby where the the most tiny tiny details sometimes become important! :cool:

This is recommended in the manual and online, they suggest the blue sockets are better for overclocking then the black one. I am totally unsure why and from testing, both channels make no difference if i put it in the blue or black dimm slots.

If someone has a reason?

just read over my posts again and the first few did seem pretty closed minded I see now. Note taken
