I re-formatted my old laptop, a Fujitsu-Siemens Amilo Li-2735, & then filled its RAM to capacity. It originally came with 3GB, & according to the specs it should take up to 4GB:

I've now got 2x2GB sticks in there but it only sees one of them:

It's Corsair value RAM, so nothing amazing but hopefully not faulty. Any ideas?
You need[U][B] dual-channel [/B][/U]ram, also get 667MHz ones because 332MHz is shit slow.
Yup, I'm a dumbass. Just found the product page again: [url]http://www.scan.co.uk/products/4gb-(2x2gb)-corsair-value-select-ddr2-so-dimm-pc2-5300-(667mhz)-200-pin-non-ecc-unbuffered-cl5[/url]
So it's supposed to be 667MHz anyway. (Isn't that the fastest my laptop can take?)
Thanks darage.
I searched and found out 667MHz indeed is the fastest it can take. For what are you recovering it though?
I bought it off a friend a while ago & it still had a bunch of his stuff on there & coupled with my clutter was getting painfully slow. So I took the easy way out & did a backup, format & re-install.

I know you're trying to help, but if you don't know what you're talking about you can cause damage to peoples computers, so please be sure you know what you're talking about.

sorry, that guy has no idea what he's talking about

follow this guide [URL]http://helpdeskgeek.com/windows-7/fix-the-maximum-amount-of-memory-usable-by-windows-7-64-bit/[/URL]
that's most likely the issue
Ah thank you kind sir; that's done the job!

You can put faster speeds of RAM in, the laptop just won't utilize the maximum speed. Example would be if you got PC2-6400 (DDR2 800), it'd only run at PC2-5300 (DDR2 667.)
When I upgrade RAM in machines, I usually get the fastest speed of the JEDEC standard. This can potentially save money in the long run if you buy a new machine that uses the faster RAM, you can just transplant it and use the old stuff in the older machine.

DDR stands for Double Data Rate. This means 332x2 (double) = 664, let's round it up to 667.
Dual (or triple, quad, etc) Channel is a multi channel architecture. That means the memory controller will use multiple modules to theoretically multiply the bandwidth between the controller and the modules. The idea is roughly the same as putting multiple hard disk drives in RAID 0 (stripe).
