Hi there community,

 

I own a vx15 with 16go RAM and wanted to upgrade to 32go so I bought a Kingston KCP424SD8/16 to get along with the pre installed kingston acr24d4s7d8mb-16. Unfortunatelly upon restart I only get a black screen. Does anybody have a hint about that ? Are the two modules incompatible ? Did anyone with the same configuration upgrade to 32 go ? With what sort of RAM unit did you upgrade ?

 

Cheers,

 

Rorshach

 

PS : the RAM module I choose was the one recommended on Kingston website for VX15

    Maybe the latency is different. Can you try swapping the places of the 2 models - this might work out.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    Swapping the two modules did the trick !! 32g recognized by bios.

     

    I'm a programmer but not really into all that hardware stuff, does latency mismatch means future problems ? Below are images from CPU-z of the module charcteristics

    The first RAM module which you already have was the main RAM. The second module which you bought has to follow the latency of the main one. In your case the 2nd module couldn't work on that latency the 1st module could. So swapping their places makes the 2nd module to be the main and then the 1st has to adjust to the latency of the 2nd, which it could do and that is why swapping the modules helped.
