How can you tell if ram is dual channel?

Answer 1

Do not confuse the term DDR or DDR2 with DUAL CHANNEL.
The 2 are unrelated.
It's not the RAM which is dual channel...dual channel is a mode the motherboard operates in to increase ram speed.
A dual channel "kit" of ram simply ensures that the 2 sticks of ram in the kit have been tested to be of identical speed so as to guarantee proper operation on a dual channel mode board.
Generally, any 2 sticks of ram of the same size and speed should run in dual channel mode, but because ram speeds can differ slightly between say 2 different batches or "runs" of say PC3200, occasionally you may run into timing issues with modules that were not specifically matched to each other.

Answer 2

ram isnt dual channel.

chipsets are dual channel.

you can plunk two sticks of normal plain jane ram into a dual channel mobo. and it will run dual channel.

matter of fact. I'm doing it now!

and uhh....

ESC skips mem testing.

lol

and DDR stands for Double Data Rate. or double the rate of SDR.

the PC number refers to the amount of bits it can transfer.

pc-3200 = 32,000bps

the DDR number stands for the common speed of the ram.

so DDR400. is a FSB speed of 200Mhz x a multiplier of 2 (it's always two) = 400mhz

just like a athlon 2.2Ghz

200mhz with a multplier of 11 = 2.220Ghz

OMG MATH!

multipler of 9 gives you a 1.8Ghz Cpu.

always wondered why cpus only came in certain speeds? cause you can't have a 11.5 Multiplier (most of the time)

if you increase the FSB spread Spectrum you can solve this though...

anyways im rambling.

bye!

Answer 3

Dual channel RAM are named DDR while Single Channel RAM are named SDR. Therefore if you look at your RAM, there should be a sticker telling you one or the other. If not, look at the copper connections on the bottom (connecting to the slots), DDR ram only have one gap while SDR has two.

Answer 4

It'll say on the stick "DDR2"... you can see if you have it by entering the "setup" of your computers "BIOS" when it boots up... computers will usually say "press F2 (common on Dell computers) to enter setup" ... other common keys are "Delete" or "ESC".

Answer 5

all i can say is don't listen to the first 2 guys as they have no idea what they are talking about. supertech has it right listen to him.
