✔ Best Answer
Your Aspire accepts a max of 8GB RAM (2 x 4GB) & it should be DDR3-1600. DDR3-1333 will work but there will be some performance loss. Please post the make/model & specs of your RAM.

BTW, if you're running a 32-bit version of Windows 7, it's pointless to increase your RAM amount above 3GB.

The specs listed for that machine say it comes preloaded with the 64 bit version of the OS so unless you reloaded your OS with a 32 bit version you should be ok with 6 gigs.

There is more to RAM than just the size and speed. Different memory sticks can come in differing timings which may not run on the other's settings. Try swapping them to the opposite slots, that may work but you will still not going to be running your memory at its optimal settings. If you have 64bit Windows then I would recommend returning the single stick of 4Gb you purchased and purchase a matched set of 8GB (2x4GB) at 1600MHz which will allow your system memory to run in dual channel mode at its optimal settings.

You have to be a little bit crazy to keep you from going insane.

As Fingers mentioned above running RAM in dual channel mode is best, if possible. Dual channel increases memory bandwidth, which is advantageous in some instances.

In your case the benefit of installing new matched RAM modules may not justify the expense. In the future keep it in mind.

To further comment on Finger reply, installing the slower RAM in the first slot may allow both modules to run at the slower speed. Conversely, installing the faster RAM in the first slot will force an overclock on the second module, which may not work.

Of course, the RAM must be compatible for your computer.
