I have added a 2933 hyperx impact ram with xmp support. But now the speed in task manager shown is 2667 instead of 2933. Can i know how to enable xmp for acer ?

    Hi,
    What was the original memory module frequency? Two  modules should be of same frequency, if the original module is 2666MHz the new module will downclock to lower speed.

    The original module also run at 2933 mhz
  • Can you check the settings of the rams memories with the cpuz program and send some screenshots?

    Already check with cpu z- first ram which preinstall is samsung 3200 ram and and the one i added is 2933 with xmp 2.0 profile. However, in task manager only shown 2667 ram speed. Its latest helios 300 btw...

    Already check and should be the problem of acer bios without xmp profile support.

    Hi,
    You have mixed speed RAM modules installed(JDEC &XMP), please post the picture of CPU-z Memory tab and SPD tab for both slots as requested by my colleague @egydiocoelho.

    Hi,
    Yes, you have mixed RAM modules in your laptop, different Profiles, speed and CL value, if you want the laptop to work @2933MHz frequency, I would suggest you to install another 8GB 3200MHz module with JEDEC profiles or buy another 8GB 2936MHz Kingston HyperX module and install.
    2x8GB 2936MHz Kingston HyperX
    OR
    2x8GB 3200MHz module( will work at 2933MHz because it's the maximum frequency supported by the CPU)

    If I just remain this configuration, does It cause any effect to my laptop ?

    No, it will not cause any problem but you will not benefit optimal function of your memory modules, for example, feature like dual-channel mode.

    isn't my ram run in dual channel mode ? Just they match the lowest speed of ram which is 2666 mhz

    TANTANTAN no your ram its not running on true dual channel performance  mode also u cant enable xmp on any laptops the bios are locked also the hyperx xmp 2.0 jedec will auto clock itself also as @brummyfan2 stated make sure youre always in dual channel mode and never mix ram with different size/clock/CL just get a proper dual channel set depending on what your cpu supports check the intel specs for it u have 2 options here either remove the samsung and get another hyperx to match the one u have or remove the hyperx and try to buy a used samsung sodimm (im guessing thats your stock ram if so its not available to consumer to buy its manufacturers oew ram you should be able to get it used from someone else) i would just throw out/sell the samsung sodimm its up to you good luck :)

    TANTANTAN if you want the best ram either hyperx or vengeance you shouldnt mix anything just get a proper dual channel ready set either 2x8 or 2x16 (when i say ready set its from the same manufacturer properly tested for that purpose) if you dont want to have more issues forget your stock ram i already gave my best advice from now on its up to you to do whatever u feel like to i dont have anymore advices regarding this  good luck

    So, I have to replace the stock ram with another hyperx impact? But will this problem happen again where 2x 2933 hyperx impact run on 2666 mhz again ? Also why my system run on lowest xmp with 2666 ?

  • TANTANTAN
    TANTANTAN Member Posts: 55 Enthusiast WiFi Icon

    TANTANTAN the hyperx will run at 2936 not 2666 you cpu only supports 2933MHz doesnt matter if u get 3200nhz or not will always downclock to 2933MHz its a waste of money do u understand it now just remove your samsung and use the hyperx only you will see the clocks  (1468mhz X 2 = 2936mhz simpple mathematics )
