    Hi,

    I do some CPU/RAM intensive tasks that would benefit from higher frequency RAM if I could get it. I'm considering purchasing this RAM kit: Kingston HyperX Impact 16GB (2x8GB) DDR3L 2133MHz Laptop RAM HX321LS11IB2K2/16.

    Just wondering if anyone here has tried running 2133MHZ SODIMMS in their P15xSM? I don't see any reason why it shouldn't run properly, but perhaps there is some limitation with the P15xSM motherboard that I'm not aware of. Can anyone attest to whether the RAM will function at 2133MHZ?

    Thanks!

    4th gen mobile CPUs support up to DDR3-1600. By design, anything faster than 1600 will still run at 1600 per the memory controller. Whether XMP is an option or not I don't recall on the P15xSM-A.

    XMP is not supported but I have a modified BIOS which allows me to manually specify memory frequency and timings. I also have an i7 4930MX (which is unlocked) so I think I should theoretically at least be able to set the 2133Mhz frequency (and associated timings) in my BIOS. My main concern is whether this can actually run stably.

    If you put in 2133 sticks that don't use XMP they will boot at 2133.

    They should be stable as long as you haven't worn out your memory slots switching sticks over 50 times. Only EM and older systems have issues with 2133+.

    That will be a matter of trial and error. :) The 4930MX has the same memory specs (up to 1600) but you might be able to get away with 2133.

    Ok sweet, thanks everyone. Looks like I'll be purchasing the kit and trying it out then. I'll report back in a week-ish!

    nah no worries :) my P150HM happily accepted 16 GB of 2133 Mhz RAM and I was even able to OC it to 2200 Mhz with tightened timings :)

    @Ragib Zaman I see no reason why your machine shouldnt accept 2133 Mhz sticks, go right ahead!

    I ran some very nice Samsung chips at 2133mhz, just be aware not every CPU memory controller can handle it.

    Could you tell me what timings you were able to run at?

    I've already ordered them so fingers crossed. Even if they can run at 1866Mhz (better than my current 1600Mhz) I won't be too disappointed.

    Have you got the ability to set the speed at the moment?
