Z77 Sabertooth & Corsair Dominator Platinum Memory..HELP!!

Hello,

I am having a problem with my new build. I am running the Z77 Sabertooth Board w the 16gb of 1866mz of Corsair Dominator Platinum Memory (CMD16GX3M2A1866C9). Everything works fine and it runs totally smooth my current issue is the memory is being read at 1333mhz and NOT the 1866MHz. So, first thing go in to bios, it is SET to Auto. Okay, should work, so I put the drop down to DDR3 1866mhz. Click Okay and then Save and Restart, Windows Boots, BLUE SCREEN, okay go back in and change it. So the Z77 Sabertooth as a WEAK OC settings and all so I went into the AI Tweaker and changed it to XMP Mode. Same thing.

Ideas? I know alot of people out there are running the z77 sabertooth and this memory. Did I miss something? Honestly, if we can get this resolved my second question would be, most likely tied into the first, how come when I go into the AI Tweaker and change the BLK freq to ANYTHING it crashes....Ideas? Please? Someone?

  1. Disable XMP and try again. Have you set the timings, voltages right? Also try resetting the bios settings and try again.
    If nothing work try to update your bios. Please do it if you know how to do it properly.
  2. Hello Xttony,

    I updated the bios first thing when I got the machine running. It is running the current updated bios.

    I have already reset anything to stock so there was no issues once I discovered the issue.

    I have not adjusted the voltages for the DRAMM.

    It is NOT running in XMP if I put it to XMP it crashes.

    Should I change it to Manual, put the DRAMM to 1866mhz and change the voltage to the ram manually?
  3. Yeah you can manually change the timings.
    Also check that the voltage settings are right. If not change to the specified voltage of the card.

    What should the timing be at? What do you recommend the voltage to be running at?
  5. The timings and the voltage (specified) should be mentioned on the ram card itself. Also set the frequency.
    The timings should look something like this 8-8-8-20
  6. This is what it would be then??

    Tested Voltage 1.5
    SPD Voltage 1.5
    Speed Rating PC3-15000 (1866MHz)
    SPD Speed 1333MHz
    Tested Speed 1866Mhz
    Tested Latency 9-10-9-27
    SPD Latency 9-9-9-24
  7. If you have 1333MHz as the default voltage then it is better to keep it that way.
    Voltages should already bet set at 1.5volts (slightly higher/lower voltage causes a lot of crashes)
    Set the timings to 8-8-8-20 and if you face any crashes set it to 9-9-9-24.

    Nothing worked. Double checked the Asus website and they say they dont support this memory, so I went ahead and ordered a new set off there list.

    Going to try that on Monday and see what it says.
  9. Where did you actually see that the cards are not supported?
  10. It only read at 1333mhz. Not the 1866mhz. If we tried to overclock it, it would just crash, we couldnt get the DRAMM to read anything at 1866mhz. I called ASUS and they said they dont support that memory. I ordered the "supported" memory and I am going from there.
