    Those timings should be fine to boot, if anything I would add some MCH voltage and manually set your ram voltage. I know you tested doing that before and had issues, but now that you have booted thru and ran that setup it should work this time around.

    If you would rather not do that, which I do suggest you try first, the only thing I would loosen is Static tRead Value. With not voltage set you may have a rough time keeping 6 going

    I Bench with Everest Ultimate or SiSandra, but there are several good benchmarks out there that are free such as RightMark (Linked in the below post with images) >>>

    Okay my casing was shorting dimm 3. I had a leftover backplate mounting from my smaller ep35 that was right behind the dimm 3 pressing against the back of the PCB directly on the pins.

    No wonder i had a power error.

    Currently running (according to Everest)

    Memory Timings:
    CAS Latency (CL) 5T
    RAS To CAS Delay (tRCD) 4T
    RAS Precharge (tRP) 4T
    RAS Active Time (tRAS) 12T
    Row Refresh Cycle Time (tRFC) 52T
    Command Rate (CR) 2T
    RAS To RAS Delay (tRRD) 3T
    Write Recovery Time (tWR) 14T
    Read To Read Delay (tRTR) Same Rank: 4T, Different Rank: 6T
    Read To Write Delay (tRTW) 8T
    Write To Read Delay (tWTR) Same Rank: 11T, Different Rank: 5T
    Write To Write Delay (tWTW) Same Rank: 4T, Different Rank: 6T
    Read To Precharge Delay (tRTP) 5T
    Write To Precharge Delay (tWTP) 14T
    Precharge To Precharge Delay (tPTP) 1T
    Refresh Period (tREF) 3136T
    DRAM Read ODT 3T
    DRAM Write ODT 6T
    MCH Read ODT 11T
    Performance Level 9
    Read Delay Phase Adjust Neutral
    DIMM1 Clock Fine Delay 10T
    DIMM2 Clock Fine Delay 2T
    DIMM3 Clock Fine Delay 10T
    DIMM4 Clock Fine Delay 1T


    Seems like these numbers don't change regardless of what i manually set in the bios?

    Ouch, hopefully you did not do any permanent damage to your board

    When you manually set something and you say it does not change in everest how many times does your system cycle after you save and apply the changes? If it is 3 times then they are incorrect settings. If only twice, then they should be saved and you should note the changes in everest. Change main timings to 555-15 and check and see if that is reflected in everest. If not you could have possibly damaged the board.

    I would start by loading optimized defaults again, and then make some changes and see how testing goes. And to make things more clear to you (So all the advanced subtimings are not shown such as Fine clock delay and ODT Settings) please check with Memset instead of everest when checking if changes are made. If you change the main 4 timings 5-4-4-12 to 5-5-5-15 and you do not see this changed in windows your board may be damaged and not applying them. Since loosening timings should not affect the boards ability to save and apply them and reboot they should be applied for sure

    Yes i am aware that 3 cycles means the settings failed to post. I read through some posts in this forum saying that. But my board cycles either once or twice so i know the settings are changed.

    Main timings such as 5-4-4-12 and 5-5-5-18 are shown in everest as changed, its the advanced timing that don't seem to reflect being changed.

    Advanced Timing Control
    tRRD...........................................3
    tWTR.......................................... 3
    tWR............................................3
    tRFC...........................................52
    tRTP...........................................3
    Command Rate (CMD) ....................:2

    Currently i'm running 402x8 @ 3.21 on my E8400, rams 1:1 on the 400 latch.

    Seems that the auto settings give me 5-5-5-18 at Static tRead of 9. Is it normal? The rams are only running at 804mhz.... This is compared to 5-4-4-12 at Static tRead 7 using the standard 333x9 and 333 latch and 2.4 multiplier.

    I'm kinda afraid of setting manual timings now because of all the bad experiences with the shorted dimm and the MUCH dreaded power error beeps...

    I don't intend to overclock my system very much... something within its limits and maintaining stock voltages and temps would be good... hence the 402x8.

    I'm afraid of burning something out... haha.

    Have you check to be sure they do not change with memset?

    Ya, This is why Auto is always suggested against. It is often wrong, to much or too little, and for sure is not the best for performance

    You will be fine manually setting things, if your board is ok
