    I am looking to upgrade the memory on my T500 from 2gb to 4gb.

    A "2GB PC3-8500 1066Mhz DDR3 SODIMM Memory" is being sold for $65 at Lenovo.
    Same memory model( 43R1988 ) is being sold for $54 at Amazon.

    There is also "Kingston ValueRAM - Memory - 2 GB - SO DIMM 204-pin - DDR3 - 1066 MHz / PC3-8500 - CL7 - 1.5 V - unbuffered - non-ECC" @ amazon for $42 and "Corsair CM3X2GSD1066 2GB PC3-8500 1066MHz DDR3 200-Pin SO-DIMM Laptop Memory" for $41.


    What are the advantaged of buying the Lenovo memory over the other two?

    What does unbuffered - non-ECC means and how does it effect the performance? Any benefits if it was buffered?

    I would suggest you take a look at newegg.com

    they tend to have a better selection and better prices sometimes too.


    as far as unbuffered and non-ECC, wikipedia it.

    I have had look at Newegg. The prices are similar, since they add in tax for my state.

    Check Crucial.com They have a 2GB module for $32.99.

    You should get 204 pin DDR3 1066MHz Unbuffered CL7.

    Any other type of memory (e.g. 1333MHz) will have to adapt to the existing module.

    If you order the RAM from Lenovo, then the memory will assume your ThinkPad warranty (e.g. 3 year onsite).

    Conversely, if you order from Crucial, and the memory fails (not very common) then you would take it up with Crucial (similarly if Kingston, you would deal with Kingston). I believe that Crucial (and most memory companies) offers very long (3 years - lifetime) warranties because failure rates are so low.

    As far as ECC and buffered. This type of memory only tends to be used in Servers and mission critical applications. It doesn't improve performance, costs more, and I don't even think the T500 supports it (ECC RAM tends to have more pins).

    ECC means that the memory is error correcting. This means for 1-2 bits of information. I used to insist upon it and it began to be hard to obtain.
