Summary: I bought a used ThinkPad X61 two months ago. A very nice little notebook, came with 2 GB RAM. Running 64-bit Linux (Xubuntu 13.04) on this computer and some PLC programming software in virtual machines (VBox) I thought about an upgrade of the RAM memory. Official up to 4GB RAM are supported, but I red in the ThinkPad forums, that a lot of people tried 8 GB RAM (2 * 4GB) instead and worked fine. So I ordered two of these Patriot 4GB RAM modules at Amazon.
Summary: I looked around for a while before buying this. PC2 memory is solid but the industry didn't make a lot of them. For my wife's older computer, this is as much as you can get. Pricey, but worth it when my wife doesn't have to wait 3 minutes for her computer to boot up.
Summary: The Patriot Signature 4 GB PC2-6400 DDR2 Notebook Memory PSD24G8002S is perhaps the single greatest piece of computer electronics I've purchased in my 20+ year IT career that ranges from my time as a graphics designer on the Mac SE30 to my current position remotely managing more than 4,000 servers at a Tier I data center.
