  • 2x F3-2133C10D-16GAB on ASROCK Z87 Extreme4 @ DDR3-1866

    2x F3-2133C10D-16GAB (4x 8GB = 32GB)
    ASROCK Z87 Extreme4, UEFI 3.00
    i7 4770K @ stock speed

    There was a terrific deal on the F3-2133C10D-16GAB kit at newegg a few days ago, so I decided to take the chance that I could run two sets. I have no intention of reaching DDR3-2133. I am just looking for a stable configuration at closer to 1.5V than 1.6V DRAM Voltage. So far, I have them running stable at DDR3-1866 with 10-11-10-31-2N and 1.500V. I basically loaded up the XMP1 profile and then amended the values I just mentioned.

    I would like to try and match the XMP1 profile from the F3-1866C10Q-32GAB kit as close as possible, but I haven't found the full suite of timings written anywhere. I only see 10-11-10-30-2N at 1.5V. Are all of the timings tabulated somewhere? My UEFI allows configuration of: tWR, tRFC, tRRD, tWTR, tRTP, tFAW, tCWL, tREFI, tCKE, tRDRD, tRDRDDR, tRDRDDD, tWRRD, tWRRDDR, tWRRDDD, tWRWR, tWRWRDR, tWRWRDD, tRDWR, tRDWRDR, tRDWRDD, RTL (CHA), RTL (CHB), IO-L (CHA), IO-L (CHB), ODT WR (CHA), ODT WR (CHB), ODT NOM (CHA), ODT NOM (CHB), Command Tri State, MRC Fast Boot, DIMM Exit Mode.

    Attached are screenshots of my current UEFI configuration.

    It's also worth mentioning that I ran memtest86+ for 11 hrs today (3+ passes) without errors in my current configuration.

      The motherboard adjusts those values based on the main values you input. Looks like everything is ready to go.

        Ah, well isn't that convenient. Thanks!
