    Would rams with higher MHz bus than motherboard's overclock better ?


    Ok so I was considering a ram upgrade to 16 GBs Kingston HyperX in a laptop of 1600 MHz bus . Kingston have a selection of three bus rams I can buy : 1600 , 1866 , 2133 . The only problem is return policy as I am going to buy them on a trip and will be back home by return due date .

    1 - I am used to over clocking my older rams using Intel Extreme program , highest I can get though is raising it to bus 900x2 (1800) where any higher and the system might freeze , now I wonder if I can get rams that were actually designed to run at even higher speeds would overclocking run at higher clock than that since theoretically it can deal with heat much better on such buses ?

    2 - Also everybody keep telling me that rams with higher bus would run fine on a system only underclocks to system bus , I have had an experience in distant past that a laptop rejected to boot with different bus rams , was that issue solved in modern rams ?

    Hi,
    You don't post anything about the actual laptop so anyone's guess.

    Well I thought the upper listing is all that matters mind you can be logically deduced from bus speeds but anyways lets cut to the chase :
    It's a i7 Lenovo laptop DDR3L that comes with 8 GBs of Samsung rams running on bus 1600MHz

    Hi,
    Look on their website and see what are memory compatibility list for speed for the device.

    now this isnt really help , the question is about overclocking , something all manufacturers frown upon , not even one manufacturer would list in specifications he can recommend a ram with higher or lower bus than the one designated for and yet everybody keeps playing with those to squeeze the last drop out of their rigs so directing someone to the formal source isnt the brightest idea .

    Hi,
    OEM's lock hardware spec's down for that reason
    If a different speed is not listed as a OEM upgrade options it's likely not possible

    You can use crucial scanner and see what it says is a upgrade option easy enough
    Crucial System Scanner | Crucial.com

    In general higher speeds are already oc'ed whether that will go higher than that depends on if they work at all

    I quite understand that if in theory they will work as people say they will work underclocked to system designated bus i.e the 2133 MHz will tune down to 1600 MHz yet however my question is , is this source of information authentic ? and the second question , would then boosting them to higher speed than 1800 MHz be acceptable since they can actually clock to higher speed than that ? got it ?

    Hi,
    On a good day a set of memory will down clock to the boards default speed
    It's not always the case
    I added some trident-z 3200C16 to my x99 rig
    It wouldn't even go to bios
    3200C14 would and works perfectly so go figure.

    If you don't want to go to the laptop's website and simply look at the spec's page (which no oem hardware police) will care lol then take a chance best odds are only 50-50% different spec's memory will post.

    Well the official manual says 1600 MHz and that is it .
    Crucial says 1866 MHz ram is available option for upgrade .
    which brings us to the question , would what work for Crucial work for Kingston ? and if i used rams of 1866 MHz i can boost them to extra couple of 100 MHz than 1800 ?

    Hi,
    No idea you'd just have to see for yourself :)
    What's the price difference crucial has a good compatibility claim/ record
    Compare the spec's of each.
