EDIT: Just did a test load of a new build. It also works for the 64-bit version. I have no idea what people are doing with this flash drive to make it not work. My advice is to make sure your motherboard is 1333MHz compatible as it is a 1333MHz stick. It is also DDR3 and does not work with DDR2 or DDR. It also doesn't work with MHz above or below 133MHz. I had weird doubts about this product just because it came packaged like a package and when you hold the package. it feels like there's nothing there. Finally, if you unfold the back cover, you will find a very thin RAM stick that is half the size of a regular one. It's fragile and very thin, but it works well. I tested it on a 32-bit PC and it works. 4GB DDR3 (3GB can be used with 32) and does what it does regardless of size. Even if you look at the Amazon stock image and realize it's misleading, this is very good RAM. Just be very careful when wearing it. looks like just a bend and it will break. maybe I just got a different model by mistake or an accident, but it doesn't affect the performance.
