Bios configuration help needed Am3+ gaming / hd video rig

Heres a list of the parts I have aquired:
-ASUS M5A97 LE R2.0 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI
-AMD FX-8120 CPU 3.10GHz Eight-Core AM3+ 125W FD8120FRGUBOX
-G.SKILL Ripjaws X Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900)
-LG Super Multi Blu-Ray Writer Drive BH12LS35

It's running with an 80g SATA at the moment, an old Maxtor drive hosting Ubuntu Linux 13.10 x64 bit
When I went into the BIOS for the first time I tried to enable what I thought were all performance enhancing settings, but I didn't really understand beyond the manual what most of them meant. It took me awhile to get it to post after that without going back to defaults entirely, but when I got them to a seemingly stable point I noticed the RAM was not being detected correctly by the OS

Long story short, its running but its unstable with frequent lockups and I'm very frustrated. I need some help configuring my BIOS properly for my RAM I think but I have all the settings required from the manufacturer, just no clue what to do with them.
I am from 90s era hardware and could build systems from that era with my eyes closed, configure them easily but haven't upgraded in nearly 10 years, so I'm just learning from scratch... it seems like it anyway from where I'm sitting.

Any help appreciated, knowledge with Ubuntu would be a bonus because I probably have something wrong on the OS level as well.

  1. is the os 32bit or 64bit????

    how much ram does the os detect????
  2. Best answer
    1) Set AI Overclock Tuner from [Auto] to [DOCP] (page 3-10 of manual)
    set DRAM O.C. Profile to [DDR3-1866MHz]


    2) Set AI Overclock Tuner from [Auto] to [Manual]
    Set Memory Frequency to [DDR3-1866MHz]
    Set first four DRAM Timing numbers beginning with CAS Latency
    for example:

    G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL9D-8GBXL
    DDR3 1866 (PC3 14900)
    • Timing 9-10-9-28
    • Cas Latency 9
    • Voltage 1.5V

    If recommended DRAM voltage for memory is higher than 1.5v, then set that manually also.
  3. At the moment I'm using the DRAM OC Profile to the preset DDR3-1866 with the rest done automatically
    THE OS detects: 3.8 GiB in system settings.
    The POST detects 4080 MB instead of 4096 MB
  4. I'm going to try the manual settings found based on the website for this exact kit:
    Cas Latency: 9
    Voltage: 1.5V
    Multi-channel Kit: Dual Channel Kit
    Timing: 9-10-9-28
    Model #: F3-14900CL9D-4GBXM
    Item #: N82E16820231474
    Return Policy: Memory Standard Return Policy

    To see if this helps and I'll post any updated info.
    Thanks for replying so fast!
  5. Based on my hardware list, what would be a suitable amount of ram for me to use? 4g is all I could afford at the time of the big purchase and I have 2 free slots.

    My ideal setup would be to dual boot to windows xp 64 bit for better support in windows games but xp 64 bit is hard to game on now, I don't like any releases of windows after xp so thats just personal preference. I'd be willing to throw on 7 as my windows environment for specific games I can't get to work right on ubuntu.
    I want to do all the HD video in linux/ubuntu, but have issues getting xbmc to transcose aac to ac3 on the fly as well as getting it to even offer support for my surround sound, which works fine in vlc (all but the transcoding on the fly) otherwise I'd go full xbmc, maybe even try the os level version of it.
  6. G. SKILL - FAQs

    I want to install more memory, in addition to my existing memory kit. What are my options?

    We do not recommend mixing memory kits, regardless of brand or model.

    By mixing memory kits together, there may be compatibility issues such as unable to boot or unable to operate at rated specifications.

    Each of our memory kit are thoroughly tested to ensure compatibility within each memory kit. And because we have not tested our memory kit with your existing memory kit, we cannot guarantee compatibility when multiple kits are used.
