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!
