Dual Channel memory,please clarify!

  rickf 23:10 07 Jun 2003

I suddenly realised that I don't know much about what this means. I am about to buy a GA-81K1100 mobo which has this capability. Can I use "ordinary" ddr memory?

Thanks huggyg!From What I can gather from the article I can just use ordinary ddr mem and the dual channel controller on the mobo doubles the rate of transfer. Am I right? I take it that there is no such thing as dual channel mempry modules.

im no expert on this.just get ddr memory that your mobo supports and you`ll be ok.

the mobo manual will no doubt be a good source of info.

to the best of my knowledge(and its not very good)it requires pairs of memory modules to be installed to gain the best performance.

someone with better knowledge will be able to advise.

although in theory you don't need to get specific DDR for this you sometimes have to.

I also have a gigabyte motherboard which supports dual channel DDR. If you read the manual you should see that it states that the ram module have to be exactly the same to work properly, for instance you need to have either 2 or 4 modules, having 1 or 3 modules in won't run on dual channel. Also both have to be of the same size and speed etc...

For example 2 or 4 sticks of 256Mb all of which are PC3200 speed. I have 2 sticks of 512Mb DDR of the same speed. Some companies have Dual channel specific DDR modules which are tested in this dual channel mode and then packed as a pair. However these are usually only required for power users, people who want to clock their ram to get more out of it.

Also if you only have 2 sticks of DDR you'll have to put them in the correct channels, if you've got a gigabyte mobo then you will have colour coded ram slots to help you out here. The ram modules must be in the same coulor slots to run as dual channel, eg. channels 1 & 3 or channels 2 & 4.

Hope all this helps.

oh and you'll be able to tell if the dual channel is running as it'll tell you during boot.
