I have just purchased a Dell XPS L702x laptop, but I think should've got one with more memory. I have 4096MB (2x2GB) 1333 MHz Dual Channel memory, and there are two spare slots, four in all.

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 :wacko: 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. :thumbsup:

The Dell memory are pretty much the same. Kingston, Corsair, G.Skill, Patriot etc are quality made ram. It most likely won't be compatible.

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.

Thanks for the responses. The Corsair and Kingston memory seems fairly cheap, so I may get 16GB of one brand and sell the 4GB of Dell memory on eBay. One more silly question; the Corsair Memory has listed under specifications Timing: 9-9-9-24. What does that mean? The Kingston Memory has Latency Timings CL9. Is that just a different way of saying 9-9-9-24, or is one superior to the other?
