Dell XPS L702x memory upgrade
Posted 14 March 2011 - 09:33 PM
I'm not 100% sure which is the correct memory to buy to upgrade. Dell look like they're selling 4GB memory modules for the XPS 17 laptop which would do the trick: Dell Memory. Are those memory modules actually any different to something like Kingston Memory or Corsair Memory for example? Is there any particular brand that is better than most of the others? What does Dual Channel mean? Is that some sort of special memory, or is it just any pair of memory modules?
If I removed the two 2GB 1333MHz memory modules and replaced them, would it be better to use memory modules with a clock speed higher than 1333MHz, or would that not be compatible with the system since the original memory modules were 1333MHz? I must sound like a complete idiot but I just don't want to end up buying something that won't work and having to return it. If anyone can answer any of my questions and point me in the right direction, I would be most grateful.

It might work. But you would get no gain from it. The memory would automatically be under clocked to 1333 by the motherboard BIOS.
Both brands you listed are quality brands.
While mismatching memory, keeping the OEM Dell and adding either the Kingston or the Corsair may work, I would stick with one manufacturer for all the RAM. Whether you buy more from Dell to add to your existing memory or completely swap it out with Kingston or Corsair.
What does Dual Channel mean? Is that some sort of special memory, or is it just any pair of memory modules?
Dual channel basically means there are two pipelines, so to speak, to transfer data to and from the memory.
As opposed to one on single channel.
