    Default ASRock 990FX Extreme3 - FSB:DRAM ration

    Hi,

    I have just acquired a new motherboard for my PC. To be more specific it's the ASRock 990FX Extreme3 edition, all good but I have a few issues.

    - FSB:DRAM ratio is 3:10, how do I need to setup my DRAM and PC freq to have 1:1 (PC Specs at the bottom at the post)
    - Almost every time I restart/shutdown my PC I have turn off the power supply and turn it on again to start the pc, if I don't do this it will remain on a black screen.
    - What is the latest BIOS version for this motherboard? how can I update the bios(if needed)?

    Thanks in advance for the answers, below you have my pc config.

    AMD FX-6300 black edition ~ 3.5Ghz
    ASRock 990FX Extreme3
    16GB(4x4GB) Kingston HyperX T1 16GB DDR3 1866MHz CL9 Quad Channel Kit
    2x Nvidia 460 GTX in SLi
    Windows 8 Pro 64bit OS

    Also I have tried to set the DRAM frequency to 1866MHz in BIOS but no success it remains to 1333Mhz, you can see in the screenshots below(Bios&CPUZ), I set the profile but it's not taken in consideration. Any suggestions?

    Hmm, check that the CR(Command Rate) is properly set to 2 in "DRAM Timing Control"

    Also, the primary timings displayed in those pics? Have you gone in and changed the primary timings? They don't jive with what XMP specs are reported to be in the SPD chip.

    And have you set an OC using the automatic OC capabilities in the OC Tweaker page of the BIOS?

    What's the 4x4GB kit part number for these?

    The latest BIOS is easy enough to discover on your own. I'm always surprised by folks who have to ask.

    Go to
    ASRock > 990FX Extreme3
    In the upper left of the page select Download then select BIOS Download

    How to flash? On the same page above is the "Instant Flash' type, my rec'd method here, of the BIOS files. There is one there with a red + , click on it and directions are given within.

    I just put that to know that I have 4 modules of 4GB each 16GB total.

    I will look into the CR and come back with the data.

    Thanks for the reply
    PS: I already have the latest bios 1.50(I found that after the first post)

    Again please, you're asking for help with memory related questions but not providing info on what memory your using.

    So you have 4 sticks of 4gb each and I am allowed to see what one of the sticks are in the pic posted. Just what do you have then? Mixed grab bag?

    So as me and anyone else isn't left in the dark playing hit and miss with our questions, as customary when asking for help on a Forum please go HERE, scroll down and fill in the "System Specs' with as much detail as you care to provide so that we know what you have there system-wise. We can only work with what you provide us with.
