| 500888 | 2006-11-21 07:34:00 | Hi, I'm trying to sort out a list of components off Pricespy necessary to put together a new computer - however I'm not sure of the difference between "ordinary" DDR2 RAM and Dual Channel DDR2. Can anyone explain this to me in reasonably simple terms, with comments on performance advantages or otherwise of the different types. I'd also like to find out about matched pairs of RAM, and the significance of the colour coded RAM sockets on the M/B. Thanks for anything you can offer. :confused: Dave :confused: |

| 500889 | 2006-11-21 15:05:00 | dual channel ram IS 'matched pairs'.........and colour coded ram slots.....well you'll see that say slot 1 & 3 will be the same colour .......put your dual channel ram into those slots to access the dual channel functionality | drcspy (146) | ||
| 500890 | 2006-11-21 18:03:00 | Dual Channel is controlled by the motherboard not the RAM so any 2 pieces of RAM (whether or not it is described as dual channel) so long as they are the same brand and same size will work. | pctek (84) | ||
| 500891 | 2006-11-22 04:26:00 | "Dual-channel architecture DDR/DDR2 SDRAM describes a motherboard technology that effectively doubles data throughput from RAM to the memory controller. Dual Channel-enabled memory controllers utilize two 64-bit data channels, resulting in a total bandwidth of 128 bits" - Wikipedia Any memory sold as "Dual Channel" will be kits that contain 2 matching DIMMS that are normally guaranteed to work in dual channel mode. 90% of the time its fine to buy matching sticks that aren't in a dual channel kit and expect them to work fine in dual channel mode. It is possible to get non matching sticks to work in dual channel but its no guaranteed and requires a bit of luck, certain chipsets are more lax in regards to how similar the memory needs to be. |
