    I'm planning to get a Toshiba Satellite A135-S2326 for my son. I was wondering if I can upgrade the memory from 512MB 533MHz to 2x1G 667MHz?

    Need your help please....

    Not sure on this particular laptop, but the rule of thumb is that you can put in FASTER memory but the laptop will downclock it to it's rated speed of say, 533Mhz. You may end up paying for a premium product that your machine can't take full advantage of.....

    Do make sure it's DDR2 or DDR3, etc, don't try putting DDR3 in a DDR2 system, etc.

    Yes. As Compusmurf said, but your motherboard might support it. Do a search on Google if your mobo supports it.

    Neither Kingston nor Crucial list 667MHz ram as an option for that model so I'm betting that it will NOT work in it.

    Well, in worst case the new RAM modules will simply downclock to 533 Mhz...

    Normally Kingston and Crucial will list ALL of the ram that will work in a system. It's not uncommon to see them list 533, 667, and 800MHz ram for a specific model. When they don't it's a dead giveaway that other ram will not work. I stand by my previous post that it probably will NOT work.

    first I concur with PapaSmurf, if neither Kingston nor Crucial list anything faster than 553Mhz products, there may be issues with installing any faster RAM. That said... CompuSmurf is also correct that most RAM modules run fine at one speed slower than its rating. You pays yo money and takes yo chances.

    I'll toss out something I discovered with many modern motherboards... The BIOS will constantly sample memory error rates and automatically adjust the clock toward its highest reliable data rate. By putting in RAM one step faster than specified for the system, I've seen many systems in effect, slightly overclock the data bus and run very well. Again, no promises this will happen with your system.
