    Can somoene look at my cpu-z Ram timings and tell me if they are ok?


    I have come to the experts for some advice!

    I have a Acer Predator laptop It's an i7 9750h cpu with 16GB of ddr4 2666 Ram..

    I wanted to upgrade to 32GB and so I bought some G.Skill RipJaws same speed and 18 CL

    I will show the before and after Ram timings on Cpu-Z.

    Can someone tell me if this is ok? I ask because I just installed the new Ram and I now have what appears to be like an odd 'input lag' when I was playing a game that I always play and it seemed to be sluggish yet the fps seems fine.. I think also when I was using the web browser it seems to not be smooth and a little laggy/jerk when scrolling..

    is this something from the new ram? I feel like something is off.

    Hope this makes sense.. Any ideas?

    thanks.

    You'll need to check the actual laptop specs to see if it CAN run two 16GB modules.
    Sometimes the RAM slots are limited in what they can physically run.

    Your laptop may be "limited" to only running, up to two 8GB sticks.

    What is the Max upgradable RAM capacity for Acer Predator Helios 300 PH315-54-748Y? — Acer Community
    Seems OK

    I don't see any problem as you replaced the two sticks with two with better specs

    Ofcourse I checked that before I bought ram, my laptop says it handles up to 32GB. So that is what I bought.

    I'm having a good laugh that the responses are about if the laptop can handle 32GB of ram... haha it's an i7 from 2-3 years ago folks haha..

    My actual question is are those timings messed up or seem wrong, because I will test again today, but I have noticed a kind of input lag and it seems the ram is running at a lower speed (I don't understand how to read JEDEC timings as it shows in picture below) than the original if you actually look at my pictures from the Default ram to the New Ram, notice the picture showing my original RAM and the New one on bottom.. is there any experts on timings or how to read this and why it's slower than my original ram yet I bought exact matching 2666 DDR4 Ram with 18 CL and my original Ram is DDR4 2666 19CL

    In CPU-Z, the "Memory" tab shows what the RAM is actually running at.
    The SPD tab just shows the various possibilities.


    For example... the bottom pic, shows what my RAM is actually running at...
    Multiply the DRAM frequency (bottom pic), times two because DDR (double data rate).

    The new RAM is running very slightly faster than the original RAM, should be OK.

    The JEDEC # timings are just preset profiles of RAM timings. It does not matter whether the Profile # used has a different # number in the new RAM modules.

    "I now have what appears to be like an odd 'input lag' when I was playing a game that I always play and it seemed to be sluggish yet the fps seems fine.. I think also when I was using the web browser it seems to not be smooth and a little laggy/jerk when scrolling..

    Real world you notice nothing on increasing RAM. You are wrongly thinking that your RAM is slower, and arbitrarily linking that to other stuff.

    Yes, thank you for explaining the ram in CPU-z to me.

    ok yes, thanks for the response, that helps. so apparently I did well with my ram ha.
