cant get RAM to clock at 3000. stuck at 2133

Ram not clocking properly. ripjaws ddr4-3000 16gb... i went into bios and set the xmp profile .... it doesn't change anything... still recognizes the speed at 2133 ghz. I tries to manually set it to 3000ghs and i get an error when the computer boots saying "overclocking failed" ... not super experienced with this stuff but I just built my first pc and I want to optimize it properly. bench scores are terrible for RAM

  1. i should mention I have an asus b150M-A mobo andit supports ddr4 2133mhz
  2. also running a i5 6600k cpu
  3. Hi wickedjermany :)

    Depends on your MB and CPU as to whether or not OC ram will work. Even if the MB supports it, your CPU IMC may not and reject your XMP profile and defaults to 2133MHz
    Very often you can get them to work by manually changing Primary Timings and Voltage in Bios but no guarantee. You can obtain your SPD info in CPUz and here you can also obtain specs on the DIMMs you are using. The best way is to select a kit from the MB QVL that have been tested.

    List your RAM modules and ill see if I can help.

    Your CPU supports DDR4-1866/2133 so anything above that are considered an OC.

    Edit: The MB QVL do have tested OC RAM and up to 4000MHz so you may be lucky.
  4. B150 Chipet DDR4 speed limit = 2133 Mhz.

    Only Z170/Z270 does higher speeds than 2133Mhz, up to 3866 Mhz.

    I get terrible bench marks on my RAM.... just trying to find a way to fix that... like very below average. I'm wokring on boosting my CPU, so maybe that'll help? I have Ripjaws DDR4-3000 (PC4-24000) 8gbx2 (CL-15-16-16-35) 1.35 v

    Any suggestions on how I can get better performance out of this?
  6. Well you have a "K" processor so an OC is possible for more performance. It will depend on your CPU cooler how far you can go and the Silicon Lottery.

    I will get your MB manual and guide you for the OC and ram settings. Give me 15mins.

    There are kits listed on the QVL with very close specs and Timings so you may be in luck.

    Your MB manual does not have very good Bios info however lets try.
    Enter your Bios
    Go to>Advanced mode>AiTweaker menu>Dram Frequency and set to "manual"
    Now to>Dram Timing control. The MB does not list what is available however you should be able to key in the listed Timings and voltage from your SPD info. See how you go.

    If its a no go then I would recommend a Bios update to 3016 if not already done so as Bios updates provide for better stability ,new RAM listings and some USB devices.
  8. With regards to OCing your CPU, Unfortunately the B150M-A MB is not equipped to OC the CPU.
    You would have to get the Z170 MB for that as the VRM phase circuitry on the B150M-A would not be adequate for overclocking.
  9. VRM phase could probably handle an OC on the CPU, the chipset just doesn't allow it however. Same for memory, higher than DDR4-2133 Mhz is not allowed. Both are locked to stock speeds

    Yea the Bios on that Board has very limited capability and the manual reflects that. It does however list higher frequency DIMMs on the QVL and an ability to change Frequency and Timings however as you say if the chipset won't allow it then that's that. In which case wickedjermany you will to return your RAM for a 2133MHz kit.
  11. Yeah, only ASRock's B150 and H170 motherboards have a feature called ''DDR4 Non-Z'' where overclocking memory is possible, AFAIK not with any other motherboards.
