DDR3 Dual Channel?

  Joseph Kerr 15:02 12 Feb 10

Hi all.

I'm looking at a Dell machine and have had a quote for a machine with single channel DDR3 RAM. Dual channel is DDR3 is not an option on that machine.

Will that make much differene?

I have little ultraportable laptop which only uses single channel DDR2- it seems to run okay. Apparently single channel can be a bit of a problem for integrated graphics. My Intel X3100 seems to run fine on single channel DDR2 533mhz (plays videos okay, Windows aero etc all work fine), so I expect that single channel DDR3 wouldn't see too much of a problem.

I only use the laptop for office/internet though, I expect it might harm performance if you have more demanding needs of your computer though- games, lots of encoding etc.

no, my needs are basic - the OS will probably the most graphically intensive thing i run apart from youtube! and there would be a separate graphics card.

thanks for that.

Like Wwiw says, for your needs, no.

But that's a strange one. Can you post a link to this PC please? G

P.S. I remember your previous thread click here

click here

I chose the cheapest Vostro then upgraded from there.

Right, I can see why some are single-channel - they are PCs/configurations with a single RAM module, which is understandable. And if you choose upgrades with 2 or more RAM modules, you'll get dual-channel.

However, there are also some PCs there with single-channel no matter what RAM configuration one chooses! I'm sure this is a typo/error on their website.

As usual their graphics cards upgrades a way over-priced - a 1Gb GT240 for £160 extra(!?), when these cards are less than half that price in reality click here. G

I'd just get the standard graphics card, it has the connections i need. I'd probably get 4gig of RAM in a 64bit system. I could go further but how much more can it take? And where do you draw teh line anyway.
