Windows Vista : Use your flash drive as RAM!

Till this date, Microsoft’s windows had two options for the memory requirement of the computer, so that the computing can be done at cheaper rates and that too without installing the physical memory.

1. Physical Memory (RAM)
2. Page File (A virtual memory file, stored on hard disk).

The page file is used by the Windows OS to cater the needs of various applications when the physical memory is fully used up. The reason for that is, that Virtual memory is slower as compared to the physical memory and thus Phyical memory takes the first priority.

However, with the release of Windows Vista, Microsoft has introduced a new technology called ReadyBoost. With the help of this technology one can use any Flash drive, SD Cards, CF Cards as the third memory option for the computer.

Now, the benefits of USB Flash Drive or Cards as a source of Memory :

1. It is faster than the virtual memory which is accessed through the hard disk drive.
2. It is cheaper as compared to the actually Physical Memory.

How can it be activated ?

In order to activate the ReadyBoost technology on your FlashDrive or Memory Cards, you have to follow these steps…

1. Open My Computer.
2. Right Click on the Removable Disk Drive and select Properties.
3. Click on ReadyBoost Tab.
4. Enable the feature by selecting the option and allocate the amount of space you want to use as memory.

Things to be noted….

1. Regardless of the fact that you use Readyboost or not, you need at least 512 Mb of memory to run Windows Vista decently.
2. If your device is not giving the option of ReadyBoost then it means that it doesn’t clear up the minimum data trasfer rate required by ReadBoost technology.

    This is my first time complementing on ReviewSaurus~ Anyway I was wandering I just bought a 2GB Kingston DataTraveler 400USB Drive With ReadyBoost from Futureshop. I used it for documents before, I wander if I clear up everything in the USB, will it still function properly and as fast as it said it can with ReadyBoost technology?

  25. John says:

    I am running a Windows 7 Ultimate Operating System and have a 32bit 3.2GHz Pentium(R) 4 Processor with 2GB maxed out DIMM DDR2 SDRAM ram slots(yes it is an old motherboard), what USB should I use?
    Can you post the minimum and maximum requirements :)
    I’m thinking of buying an 8GB USB to readyboost it.
    So can a third party USB with the requirements work?
    Using a desktop computer by the way.

  26. Vaisakh says:

    Can anyone tell by how much my ram will increase when i use a 4GB flash drive?

  27. Juan says:

    coooool im doing it right now :) 1GB of RAM + 2GB of flash = 3GB combined RAM :) it works like a charm

  28. LsTrOfSmG says:

    Major misinformation. Using a readyboost enabled flash drive is in no way equivalent to using a flash drive as RAM.

  29. Masum says:

    So Ralph, If I take out my flush drive while running ReadyBoost on it will it crash the windows. It could happen accidentally.

  30. Mango 69 says:

    Hey Hey can I use my hard disk as graphics memory cause the inbuilt one is just 32 mb ???

    • Mayank says:

      well, ram is always faster than using hard disk. so eventually your computer will use harddisk for graphics memory, but it won't make much difference…
