    Sure, these are rated for 3200 cl18, and are hynix chips. So no guarantee that my settings will work for others.

    How much of those have you tweaked?

    Things I've changed going from 3000/3100MHz to 3200MHz, off the top of my head.

    Cl 15 >16
    tRCD/tRP 17 >18
    tRAS 39 >43
    tFAW 26 >39
    tRFC 420 >560
    tRRD 12 >4
    tTRP 9 >12
    tWR 18 >24

    Here's a screencap of them running @3100 CL15 with the old chip.

    Looks like a good set of timings for the speed :)

    Thanks :)

    @Meaker@Sager have you tried overclocking the ram with all dimms populated? I've been digging through the forums and from what I've read some of these boards have an easier time going faster with all slots filled.

    It seems that the timings are too high for such frequency. Can you do a memory test in Aida64? :rolleyes: I want to compare with your result.

    Yea, the stock timings are garbage. Hence why I dropped them to cl 16. I'll do a test later and get back to you.

    I didn't bother to screencap the aida64 cache & mem benchmark as it hides some of the numbers behind "trial", so here are the numbers:

    3200 cl16
    Read: 46827
    Write: 48685
    Copy: 45737
    Latency: 49.8 ns

    I'll have to tighten them up and see how the sticks scale with voltage eventually.

    @jc_denton, Good result, I'll do a test in the evening. It seems your memory is better than mine.:D

    I think cl15 3100 might have been even better, as both primary and secondary timings were tighter.
