Noob needs help with bios ram settings

I currently have 12gb 1600MHz, 9-9-9-24, 1.65V RAM installed (2x2GB, 2x4GB).

I just noticed in CPU-Z that the DRAM frequency was set at 666 MHz.

Can someone tell me if this is correct or do I need to do something in the BIOS to fix it, as I have never touched the bios settings for the ram on this new motherboard.

I have been getting a lot of BSOD (page fault in nonpaged area) since I tried to overclock my CPU, so I am not sure if its related to the ram.

Any ideas?

  1. Best answer
    The DRAM it shows is supposed to be multiplied by 2. The blue screens you have been getting might be related to the RAM because of the non matching gigabyte RAM kits. Try going into your BIOS and find the RAM option OR just go to your system status in the BIOS and check if it is 1600mhz. If it is not, change it back to 1600. However your bluescreens could also be a result of the overclocked CPU. what motherboard do you have? If you are OCing with the stock cooler, stop.
  2. What mobo and CPU? and what actual model #s of DRAM?
  3. Hi,

    Mobo: Gigabyte P55A-UD3R
    CPU: Intel i5 750 2.6GHz

    I went into bios and enabled an XMP profile and now CPU-Z is showing 800mhz instead of 666.
    CPU-Z also shows:
    FSB : DRAM: 2:1 - is that bad?

    RAM is all the same type, just 2gb and 4gb sticks (XMS3 PC3-12800 1600MHz DDR3 DIMM 240pin CL9

    My CPU is back to its default settings (but I would really like to overclock it back to 3.5GHz again).

    So, now that the RAM is fixed, try OCing your CPU again and if you are still blue screening, then either turn down the OC or remove it all together. Hope I helped!
  5. Looks good, now that DRAM is correct and stable can OC the CPU
  6. Thanks guys. Do you think the fact it has been running at 666 MHz all this time could have been causing the problems?

    Yes, I believe so. Glad you got it fixed!
  8. I agree with Xexoxix.

    Yes, they were running at the mobos default, so prob at 1333 they had some loose timings which can cause problems
  10. Hey so I just tried to OC my CPU again but now my RAM speeds have changed and showing 875MHz.

    I changed the bios clocks to 175x20 to get up to a CPU speed of 3.5GHz.

    Any idea why the ram has increased as a result and how to get it back to 800? I don't really want to OC the ram.

    Hope I am making sense, thanks!
  11. Can anyone help? Still stuck trying to sort this mess out!
    I am also getting blue screens everytime I open speedfan now (since the OC - IatoR.sys)

    I don't know - is there an option in the OC program you're using to turn off RAM adjustment or something? I don't really OC my CPU.
