THIS WORKS WITH WINDOWS 7,

1.) Plug your flash drive into one of the USB ports. Make sure you have no important files saved to the flash drive. The higher the memory on the flash drive, the more RAM you can add to you computer, however, certain computers can only use so much.

2.) Click Start > Computer > Right Click your flash drive > Properties

3.) Go to the Ready Boost tab and check the "Use this device." box. Now drag the slider all the way to the right, so you can use your flash drive to it's full potential. Click apply then Ok.

As you can see I have added 1902 megabytes of RAM, which is almost 2 Gigs.

4.) Now just to check if everything worked open up your flash drive and you should have a ReadyBoost file located inside of it.

And there you go your computer should now run more smoothly! Remember the more RAM you add the more of a difference you should see in performance.

Some IMPORTANT Things:
-The RAM added will not show up in your installed memory because it is "Virtual memory".
-Do not unplug your flashdrive while your computer is on, turn off before unplugging. Computer may crash if unplugged while computer is on.
-You can use as many flashdrives as you have USB ports.
-I recommend changing the name of you flashdrive to something involving "RAM" so you don't save any files to it.
