How To Increase PCs RAM using a USB drive

ReadyBoost is designed to help when your PC's memory is running low. Low memory can make your computer sluggish because Windows, which needs a place to stash data, turns to the hard drive. Flash memory offers a speedier alternative.

ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards. 

ReadyBoost requirements for USB keys are as follows:        

§  The USB Key must be at least USB 2.0.

§  The device must be able to do 3.5 MB/s for 4 KB random reads uniformly across the entire device and 2.5 MB/s for 512 KB random writes uniformly across the device.

§  The USB has to have 64MB free space

To use USB as a RAM memory . Do This :

·         Insert Your USB Pendrive.

·         Right click on your pen drive and get into properties.

·         There you would find a tab called “Ready Boost”.

·         Select your 3rd Radio Button over there stating “Use this Device”.

·         Wait for some time till the RAM space gets ready.

·         Restart computer to feel the effect.

                                                        

If your USB FLASH DRIVE tells you that you can’t use the ready boost then it means that it doesn’t clear up the minimum data transfer rate required by ReadyBoost technology.
