    The computer is still rebooting under the settings I posted above. Should I try Optimized Default and see how it goes? And if it still reboots under that, are there other ideas?

    If you are using the same settings from post 8, try these changes.

    WAY less MCH, try 1.2-1.24
    Dram Termination set to Auto
    Driving Strength Profiles for each channel set to 1066 (If that fails set 800 but it should be fine/best)
    CPU Ref set to Auto
    C1E Set to disabled
    PCIE Freq. set to 100

    MCH Ref, did you set this correctly? With VTT at 1.20 then adjust MCH Ref, then adjust Vtt back to value you want to use? If so ok, what value is it you set for MCH Ref with Vtt at 1.20?

    Alright I did the top changes . What does the driving strength profile do? I had it at 800 a while back but it didn't seem to do anything so I just set it to auto. And when you're asking me about the MCH ref and the vtt, do you want to know what the ref is when the vtt is 1.2? Cause I did change the mch ref after i changed the vtt. If you're asking what the mch ref is when teh vtt is 1.2, then the ref is at 0.8

    Choosing a driving strength profiles just sets a set amount of settings for all the other settings on those pages, normally at 850-950 using 1066 is better

    MCH ref must be set a certain way, that is why I asked what I did. More info in the MCH GTL Ref link in my signature on how this should be done.

    Basically the proper way to set this is to set Vtt to stock 1.20, then adjust MCH ref to desired amount, then raise Vtt back to desired amount and MCH Ref will self adjust keeping the proper percentage.

    I suggest you try .68-.74 MCH Ref with various final Vtt amounts

    The computer restarted again so I might change the ref. Any other ideas in mind?

    I'd try setting the MCH Ref properly as I advised, but you will need to try out several amounts of MCH Ref and Vtt

    Ok, so I tried the MCH ref from 0.68 to 0.84 and the computer still restarts. The lower the voltages, the computer never posted but once it got past 0.70~ then it started to last a couple hours and then when it reached 0.84, it stayed on for a day and a couple hours until it restarted a couple minutes ago. I tried 0.88 and it restarted at the login screen so I'm going to keep it at .84 until I figure out what else to try.

    OK this is good progress testing you have done.

    What Vtt (Final after MCH Ref change from 1.2) were you using for these tests, and what MCH Voltage?
