    Hey guys,

    I just bought a T400 and its been spectacular so far! Out of curiosity though, my order sheet promises me PC3-8500 DDR3 memory, rather than DDR2...today when I looked at the EVEREST and SIW report, I have 3GB of DDR2 memory, which is rated at 667mhz. That's definitely not the same.

    WTH? should i take this up with lenovo?

    The T400 isn't capable of taking DDR2, so I bet it is a software error. What speed does Everest show the RAM is at?

    All of the production T400, x200, etc. use DDR3 RAM. Some of the review units had DDR2 but they had early motherboards. I think a lot of the software packages (Everst, CPU-z, etc.) can't see DDR3 properly (I have the same issue with my x200 Tablet). If you want to verify that you have DDR3, just turn off your computer, flip it over, remove the memory plate, and look up the model number of the installed memory.

    It is just reading it wrong. Open up your memory bay and see that it is ddr3 sodimm 204pin ram :p if you are so worried.

    Download CPU-Z, and upload a screenshot of the SPD page. (Post a half-link, since you're under-15)

    The second shot seems odd in that none of the entries are filled out. My guess would be CPU-Z isn't reading the memory properly.

    fair enough -- i suppose there ought to be other markers to look at for the DDR2

    however, there is one interesting bit if u notice the clock speed of the memory is about 531.8 and theres a 1:2 multiplier on it...basically, its running just shy of 1066 (which should be its speed if it were the DDR3) right??

    Thats DDR3. The CL=7 is a dead giveaway.
    DDR2-SODIMM do not support timings of 7-7-7-20.

    Anyway, this has been brought up many times. If the manufacturer says it is DDR3, it is DDR3. Software haven't been updated to show DDR3 modules properly yet.

    The frequency is shy of 533MHz, because 1066MHz is an on-the paper figure. I/O Clocks throttle due to the FSB throttling. Anyway, it is performing at 1063.6MHz, so its fine.
