  • Boot failure after trying to activate Profile 2 + RAM keeps as busy as before

    Hi everyone,

    I recently bought a pair of G.SKILL F3-14900CL9D-8GBSR DDR3-1866 RIPJAWSX SNIPER (dual kit, 4+4) in order to improve my RAM. Before I already had a couple of these, that resulting in a total of 16GB for my PC right now.
    However when I check the speed of each one my computer indicates they are running at 800 MHz instead of the 1866 they are supposed to run at, or the 933 MHz, if the system is supposed to show half of the speed for each card as it is the whole kit that runs at 1866MHz.

    After checking several forums I found I might had to activate Profile 2 in the BIOS. I activated it but when trying to boot the PC I got a message such as this one.

    I already checked if my motherboard and CPU support these speeds and they do as per the manufacturer's site.

    This is what my CPU-Z shows:

    Image 2 here (SPD): https://ibb.co/ySJJNrj

    I bought this extra kit because when I used to boot my computer my RAM was already using 50% of its capacity. However with this extra kit it remains the same, just after turning it on my RAM is already using 50% of its capacity (now it is 16gb instead of 8gb). This is something I do not understand either. As now I have doubled my RAM, it is not supposed to be as busy as before. That made me think maybe the PC did not recognize this new kit? I already did several things in order to clear all the programs and stuff automatically working from turning on the PC as well as cleared the cach?.

    As for my hardware, I have:

    - AMD FX (tm)-8350 Eight-Core Processor, 4000 MHz
    - Gigabyte 990XA-UD3
    - NVIDIA GeForce GTX 960

    I thank you all in advance for your kind help,

    Are you using the latest BIOS for the motherboard? Each memory kit is designed to be used on it's own, once a secondary kit is added, the performance profile and rated specifications can no longer be expected. For this particular system, you can try boosting NB Core Voltage and/or DRAM Voltage to see if you can stabilize full slots at DDR3-1866, however if not, it may be best to stick with DDR3-1600.

    You can also test each kit separately to ensure both can work fine at DDR3-1866.

    Here is a guide that may help:

      Good morning,

      Sorry for my late reply, I have been AFK these last days.

      Are you using the latest BIOS for the motherboard?
      I don't know to be honest, I suppose not. I just tried to download the last version from the Gigabite website but apparently the .exe is not valid for 64 bits. Which I find weird ??

      Even if working at 1600 instead of 1866, what I do not understand is why the computer still has 50% RAM busy from booting if I just doubled the capacity from 8GB to 16GB... I already did several things in order to clear all the programs and stuff automatically working from turning on the PC as well as cleared the cache.

      Thank you very much,

      Haldir

        It is possible the two separate kits can not work well together. Each memory kit is designed to be used on it's own.

          Unless you have a bootable DOS-drive prepared, just unpack the Zip, copy the BIOS file (the large one) on a FAT formatted USB drive, reboot to BIOS and launch Q-Flash to update the BIOS.

          The motherboard manual should also cover this (in most cases).

          In general newer Windows versions also are optimized to utilize more RAM, if it is available.
