This laptop comes with 4 GB of RAM. At the time of purchase, the seller added another 4 GB stick, which reset the memory speed to 1333 MHz. I want to increase the memory speed to 2133 MHz (which most laptops have) but there is no option in the BIOS for that. How do I proceed?

    Hi,
    Could you please provide the memory brand and model number, your memory seems to work at 2666MHz, if you are in doubt, please install CPU-z free program, go to Memory tab and SPD tab, post the snip of them.

    Sorry for the late reply. 
    The Frequency used to be 1333 MHz in the Task Manager, but due to some reason, it is showing 2400 MHz (I noticed it just now). The only thing I changed in the BIOS was Function key behavior (so that it recognizes F1-F12 as function keys rather than media keys; media keys are fn + F# now).

    Edit: The DRAM Frequency shown in CPU-Z "switches" between 933.0 MHz and 400.0 MHz in like every 2 s.


    Sorry for the late reply.

    The snip of the SPD tab of CPU-Z:

    Hi,
    I see your system allocates 1.1GB for Hardware reserved, that may be the problem, could you please remove one memory module and take the snips for CPU-z(memory tab and SPD) and Task manager, then do the same for the other module as well, please post all the snips clearly showing which readings for which module, I suspect one of the modules may be incompatible.
    You could also take out each module and wipe them clean with soft cloth and see whether it helps, 1.1GB is too much for Hardware reserved.

    All of these notebooks (from multiple sellers; each of them adds a new stick for a total of 8 GB RAM) have 1.1 GB for Vega 8 iGPU. I did not do anything to this. I did see a video which had compared the performance of ~0.5 GB vs ~1 GB in GPU intensive tasks and there was a difference. Also, this does not have VRAM and the GPU only has system memory to work with. So having less memory allocated to it can bottleneck it.

    Hi,

    Then you have to let the system decides how to allocate the speed to suit your system, it's impossible to manually control the speed.
