    Well some organisations are willing to pay that amount if they feel that they can derive some benefits from it (but not many). Someone is Oz was interested in getting the machine from Lenovo ANZ, but this option wasn't available to the individual end customer they were only available to the corporate customer through special order. I would think the W520 when optioned with the 32 gigs would cost more than 5000 dollars in Oz, which is a lot of money.

    I'm unsure the max ram limitation depends on the cpu. For example the hp8460p with i7 2620m (as x220) officially supports 16gb. It would be nice if the x220 really support 16gb as well, just for piece of mind

    I can confirm that 16GB works perfectly on the following X220 setup:

    i7 2620M
    Windows 7 Ultimate x64

    ================================================================

    Just tried to run 6 virtual machines concurrently, while running 4 x R sessions. Now 16GB is plenty! And I no longer need to worry about saving memory!

    I'll run memtest86+ for some time and see if it's perfect.

    Damn, I wish I had a real reason to put 16gb into this thing...

    On a side note, have you noticed a reduction in battery life?

    lol dang 13.1 GB used for your VM's.

    Why would you have a reduction on battery? With that much RAM, you wouldn't be hitting page file as much, (had you had a mechanical HDD) you would be saving more battery than using more.

    Sniper,

    Where did you order the Micron SoDIMMs from and how much did they cost?

    Thanks

    Power is still required to keep ram powered up. Prob around 1.5-1.6 volts? I figure, since the density of the circuitry is greater on those 8gb sodimms, they might also require greater current flow.

    People running with 1stick of ram already get better battery life than those two have 2... I was wondering of the added density of the ram added to the battery reduction.

    I'm still running memtest86+ on it now so I'll see the wattage in Power Manager, and the voltage in sensor readings in AIDA64 later.
    I ordered these from Crucial's website directly (Crucial is Micron's consumer brand). That's $740 USD on their website now.
