    tRD 9 should work, once you have the correct voltages, 10 shouldn't be needed at all.

    There is no difference in BIOS between 1.0 and 1.1 on this board, you can use the latest one listed. And yes, you can flash to any BIOS you want, and then backwards to any one as well as long as your CPU is still supported by the older ones.

    A few updates:

    I was able to get 399x2.00B nearly stable with 4-4-4-12 timings with tRD 8. The voltages are nowhere near the values recommended to me. This is what it looks like:

    CPU VTT: 1.20v
    MCH Voltage: 1.16v
    VDIMM: 1.90v
    VDIMM Termination: 1.045 (55% of VDIMM)

    After two days of memtest, I have a total of five errors. That's much better than the previous 400x2.00D setting with 5-5-5-15 timings with a tRD of 9 (several thousand errors after two days).

    My VDIMM could be dropped to as low as 1.86v, but I chose to set it to 1.9v in order to give it a nice, healthy buffer. 2.0v, which is what it is rated at, caused increased degradation.

    I increased VDIMM termination just because of the fact that a higher termination decreases voltage noise (if I understand that part correctly), but I didn't go any higher because it was recommended that it be set no higher than 50% VDIMM. I don't know how much further I can push it before it becomes unsafe.

    When MCH voltage was set to 1.1v, I had zero memory errors, but I would get BSODs in Prime95 blend, probably because memtest doesn't stress anything more than the controller. Not a lot of CPU, PCIe, or other northbridge related stress. Setting to 1.16 fixed this.


    So, with that mentioned, is any new light shed on this situation? The closer to standard voltages, the better it operates. I don't know if it's a PSU or MOSFET problem, a heat issue (which I seriously doubt), or if it's just the fickle nature of the P45. Either way, it appears I am getting closer to appropriate voltages.

    Where would I go from here? Which settings should I try changing next? I haven't touched the reference voltages, as I have no idea how they work.

    Have you tested with:
    • Intel BurnTest or LinX: 10 loops maximum using the maximum amount of memory
    • Prime95: Blend, small FFT and large FFT tests (8 - 12 hours or more for each test)
    Watch your cpu core temperatures while running IBT or LinX.
    Are you using the latest version of Memtest86+?

    As I said previously, I can run any prime95 test practically forever without error, at least until my memory stability degrades (which seems to happen on a fairly consistent rate). The highest temps I've ever seen was 44c for system, and core 0 tJ (always the hottest) was 74c.

    However, I just ran IBT, and my CPU was not too happy about it. In the middle of pass 4, it failed. Core 0 tJ went from 68c to 82c in the matter of two seconds, followed immediately by a power down. Suffice to say, I never want to do that again.


    As for the template, here is the modified version of what was posted in the OP to reflect my current setup (399x2.00B) instead of (333x2.40B). Compare and contrast :).

    I would use VDim Ref Auto, and set your ram to the rated amount, then test things as you have been.

    I would also set Driving Strength Profiles, to your ram speed or one above if it will boot.

    Do not trust any setting value you see in the BIOS, check voltages with Easytune and memory timings with Memset
