Hi everyone,

I bought a Acer nitro 5 an515-43-R4MW 3 month ago and I plan to change the original ram from 2x4Go to 2x8Go.
Google tells me that I can't change my RAM XMP Profile because i can't access to this setting in BIOS.
With CPU Z i saw that max bandswith is 2666Mhz and DRAM Frequency is 933.0Mhz, this mean that my RAM is limited by my bios to 1866Mhz? (Return in 2012?)


Here, snapshot of CPU-Z :

My question is my RAM is really limited to 1866Mhz,and if so, is there no way to stop this limit?

Thanks

    Good evening des29 !

    This model does not have native support for RAM in the frequency above 2400Mhz or the XMP profile.
    Then you should use RAM modules of a maximum of 2400Mhz without XMP technology.
    The XMP profile that your Bios does not have limits access to only the base frequency of RAM.

    When idle and no load the cpu underclocks so the integrated memory controller, therefore what you see in cpu-z is true. This cpu is capable on "turbo" mode to hanle 2400 on  single channel and 2666 on a dual (check my bench in the signature). Native supported speed is 2400 thou.
