Using USB as ram...

    Anyone know much about this?
    How effective is it?

    with 3gb in the laptop, is it capable to boost performance that much...? (and same for a 512mb)

    If so what 'ratio' does the USB's space convert to RAM... (ie 4gb mem stick = 4gb ram?)

    Thanks :)

    it's not worth it for anything over 2GB. You would see more improvement going 64bit os and changing the 1GB stick to a 2GB for dual channel (it works best with 2x the same size sticks).

    I'm using 64bit OS, and meaning for my laptop, which has a restriction it would seem of 2.87GB (motherboard?) irrelevant of 3 or 4gb of ram...

    that number sounds more like the gpu is taking some of the ram to me.
    Have you tried 2x2 sticks

    I tried 2x2 when I had vista 32 and got the same value. (with 2x2 and 2+1)
    Not quite sure why I'm after more, but if I get the situation where I need it, wondering how effective putting a 4gb (or my 16gb) mem stick with 4gb (max) allocated for readyboost...
    Also looking at getting a very cheap eeePC for more portable situations and as that has 512 in, was wondering if this was a cheap and cheerful option if chromeOS allows it.

    if you still have the ram try it now you have 64bit.
    On the eeepc you would get better performance from paying about 20 quid out on some proper ram, usb ram is slow.

    I don't, I borrowed it in the shop I got my 1gb from :p ...
    not ideal to open one up to test really, if I'm not planning on buying unless it works..

    Yeh most likely a better option.
    Like I said was after cheap and cheerful as I already own the flash. And hence asking is it any good :p but you've answered that.

    Sigh, why can't I just have £1000 to buy a MBP ;) ;) ;)

    You can, but first you have to earn it or get a bank/person/fish to loan it to you :p

    USB flash drives are too slow for RAM really. Might as well use them for funny pictures or something :p

    But then I'd need the apple cover, and it would help to have a carrying case, oh and the cable to connect it to a monitor, and some apple software, sad times when I'd need £1000, so I think I'll just buy the £60 eeePC with extra ram?

    764.15 - mbp
    47.00 - applecare
    24.95 - incase sleeve
    17.80 - mini dp to vga or dvi

    which apple software?
    iwork? £54.



    altogether (with no iwork)
    £853.90


    and you can get the incase sleeve for cheaper online, and probably the same for the mini dp.

    Would the USB transfer rate not be incredibly slow compared to that of proper ram? even USB2 is like a slug in comparison (I had same argument about external HDD's)

    Yeh, it would seem that way, I just wanted to see how worthwhile it is with the speed deficit...
