Stupid laptop RAM upgrade question....

Ok, I know desktop computers fairly well. I've done many, many upgrades before. But, I just got a cheapie Gateway laptop (MX-6429) that BB had on sale this weekend and am looking to upgrade the RAM. I haven't cracked this thing open yet, but when I do I'm looking to add RAM. So, is this only going to have one slot or multiple? It came w/ 512 MB, and I'm looking to double it. Not sure if I need to just buy another 512 MB or need a full gig and swap out the original RAM.

If it runs dual channel you're better off trying to match the existing RAM and using two 512s.

You're gonna have to open it up to do that. And it's gonna be as easy to look at how many slots you have and how they're populated as it would be to look it up. Maybe you already have 2 256s.

According to the Gateway specs, it requires PC2700 DDR SODIMM. So, if it's paired already, buying 2 512's is the way to go, huh?

If you want a gigabyte and if it has two slots and if it doesn't already have a single 512 installed.

That is a pretty good system for the price! Since it comes with 256MB RAM and is upgradeable to 2 GB that tells me there is only one chip. Usually the installed RAM chip is under the keyboard and the open slot is under the laptop, I would check there first. However on these new widescreen laptops I have been seeing both RAM chips installed under the keyboard.

Before you buy 2 chips I would find out how many RAM chips you do have. Also I don't see why you would have to install 2 identical RAM chips as I have not had to that for a couple years, and I would reccomend you buy a 1 GB chip. (This will help greatly with Windows Vista!) Even if the two chips don't work together you can take out the 512 and sell it on Ebay and have an extra slot to upgrade.

Totally depends on whether it is capable of dual-channel operation. If it is, and you want to get the extra speed that provides, you're going to need two fairly closely matched RAM modules.

I should do some testing on my laptop inventory, most of my laptops have two identical chips but I have a couple with mixed chips and I did not see any difference in speed. My personal laptop has two different chips, I was thinking about upgrading anyway.

I would still go with the (2) 1 Gig chips if he can afford it.

I wouldn't spend much extra money on dual-channel myself. It only adds about 5% to the overall speed so I wouldn't spend more than about 5% on the RAM unless squeezing out every bit of performance was really necessary.
