4GB DDR2 Dual Channel Vs. 6GB DDR2 Single Channel

Hi,

I have a question regarding the gains and loses of Dual Channel RAM. Is it true if you get an extra stick of RAM, and stick it into another socket, that you will kill the dual-channel advantages for having 3 sticks and not 2 or 4? If so, by how much?

  1. Well I know that with the i7core you can have 3x or 6x but if you have an amd it is 2x or 4x but I could be wrong. Sorry that is about as much as I know I am still learning too.
  2. No, this is not DDR3. This is DDR2. DDR3 can only go Triple Channel.
  3. not entirely true. There is dual and triple channel DDR3. IE: The lga1366 processors use triple channel DDR3, where as the Phenom II and the Core i5 processors use dual channel DDR3

    I ment that DDR3 can only go triple channel, and not DDR2. Not that DDR3 does not have dual channel support.
  5. With DDR2 motherboards I think its ider 2 or 4 DDR2, if using XP Pro 32-bit, otherwise it will spoil the dual channel you just have one DDR in. I´m going to buy a Dual channel DDR2 motherboard and my first thought was to get 4x1 GB so I can take the last one away if XP struggle of having more than 3 GB RAM, but my retailer says I should buy 2x2 GB DDR2 to use in only one (2 slots) of my dual channel, so I later can upgrade to Windows 7 and get more RAM if I whant to. How many DIMM slots do you have and what OS do you drive?
  6. Really no one has answered this question. I have 4 gb dual channel running on an xfx 680i board with windows vista. i have 2 1 gb single channel laying around . The question is , if i put them in; will it kill the dual channel. I think it will. But which is better, 4 gb dual channel or 6 gb single channel. Which has more speed and response time. Will the increase in amount offset the decrease in speed?
  7. 4GB Dual Channel > 6GB single channel, generally speaking. Just an FYI, the dual channel architecture was designed to eliminate the bottlenecking of single channel RAM when the FSB of the CPU was greater than the RAM
