    Hi guys, i'm looking to pick up some ram for a 2740p and was wondering if this would work: Scan.co.uk: Corsair Memory 4GB DDR3 SO-DIMM PC3-10666 (1333) Dual Channel Laptop - CMSO4GX3M1A1333C9

    What do you think of that module? is it any good? Also, the system i'm buying in the uk has 2gb of ram (i'm guessing it will come in 2x1gb sticks) so i was wondering if I should buy 2x 2gb sticks and chuck out the 1gb ones.. OR stick in a single 4gb stick keeping one 1gb one. i.e. giving me 5gb in total.

    I'm assuming that the latency of the 1gb sticks will be higher than that of the single 4 and so might be a bit slower, but i was just wondering if drawback of latency would prevent the 5gb system working as fast as the 2x2gb (4gb) system.

    what are your recommendations?

    thanks!

    According to the 2740p service manual,
    the 2Gb model comes with 1x 2Gb stick,
    4Gb model comes with 2x 2Gb,
    6Gb with 2Gb and 4Gb sticks,
    8Gb with 2x 4Gb.

    The stick in your link should be just fine. It will run at CL7 latency settings @ 1066mhz though instead of 1333mhz @ CL9.

    Hi, newbie question, what speed ram should I get? 1333 or 1066 Mhz?

    Mine came with 2x2gb Samsung ddr3 10700, but according to CPU-Z, they are running at the maximum of 667 Mhz with dram frequency of just 531 Mhz.

    I'm planning on getting the pair (newegg link below)
    http://www.newegg.com/Product/Product.aspx?Item=N82E16820231294&cm_re=ddr3_1066_laptop-_-20-231-294-_-Product

    1333 versions are about the same cost as 1066.

    Hi ilee01,

    According to the tech specs, it can accept 1333MHz RAM but it'll clock it down to 1066MHz (DDR3-1066/PC3-8500) since the 2740p's memory bus maxes at this speed.

    I always presumed that to be true; any idea why HP stocks the 2740 and 2540 with 1333mhz RAM?

    So, guys. what's your recommendations? 1333 ($101 for Corsair 2x4gb) or 1066 ($94 for 2x4gb) I do not see any advantages of going with 1333 since there is no OC capabilities here.

    get the 1066Mhz set (no point in upgrading to better ram if it can't be used that properly... besides the likely hood you would see any improvement from the 1333Mhz is none)

    I've tried Corsair and a few other brands of RAM in both my 2710p and 2740p and none of them have worked properly with anything but HP rebranded RAM...

    Reminds me of the early nineties when various manufacturers would swap pins etc to make sure that consumers only could use their overpriced rebranded components...
