My family just got a new toshiba A135-4656(something close to that). It has vista, and I really don't want to go through the hassle of getting XP, but its only got 512 RAM running with vista. So, saying that, I really want to get some upgraded RAM for it. I've been looking around on sites for RAM, and I've found some decently priced RAM, but I'm not sure whether I have to stick with the PC2-4200 533MHz, or can I jump to the PC2-5300 667Mhz? Is there no way to tell other than getting it and trying it?

Thanks in advance.

It depends on what your motherboard supports. If that's the speed your RAM is now it's probably safe to assume that's the highest speed it can go so you shouldn't but the 5300's. There's no way of upgrading without changing the motherboard.

I just looked up your machine at crucial, here is the link to what was found: http://www.crucial.com/store/listparts.asp...te%20A135-S4656

Your machine supports up to 2 gig , DDR2-4200 only.
The name says it all -- 59 and holding permanently

In general you won't notice any significant change between the 4200 and the 5300 despite the change in clock speed. I suspect that the mobo would downclock the faster RAM to slower bus speed anyway. And the Toshiba BIOS doesn't offer a whole bunch of options for you to tweak it.

What's your Windows Experience score? That'll tell you where the maximum bang-for-your-buck is. If the memory is the lowest score, then adding memory will make it perform better (which I suspect will be the case with only 512 mB installed). Vista Home Basic will work OK with 512 mB, but once you start using it, it'll clog up quickly.

Right now it seems as if 2 gB is the sweet spot for Vista ($ vs performance) although 1 gB will work well (especially with Home Basic).
