    You can work on trying these changes >>>>
    Code:
    tRAS.............................................. ..12/15
    
    Advanced Timing Control
    tRRD........................................... 3-4 
    tWTR.......................................... 3-5
    tWR............................................ 3-6
    tRFC........................................... 46-50
    tRTP........................................... 3-6
    Command Rate (CMD) ....................: 2 5 << ????  5 is not a option, only 0-3.  Set this to 2
    
    Channel A
    Static tRead Value............................: (6) 7-11 8 << See below comment
    tRD Phase0 Adjustment...................: Auto
    tRD Phase1 Adjustment...................: Auto
    tRD Phase2 Adjustment .................: Auto
    tRD Phase3 Adjustment..................: Auto
    Trd2rd(Different Rank)....................: Auto
    Twr2wr(Different Rank)...................: Auto
    Twr2rd(Different Rank)...................: Auto
    Trd2wr(Same/Diff Rank)..................: Auto
    Dimm1 Clock Skew Control...............: Auto
    Dimm2 Clock Skew Control...............: Auto
    
    Channel B
    Static tRead Value..........................: (6) 7-11 8 << 8 is about the best you can do with MCH 400, you can try 7 though but if you do test before you lower voltages or tighten above timings
    
    tRD Phase0 Adjustment...................: Auto
    tRD Phase1 Adjustment...................: Auto
    tRD Phase2 Adjustment .................: Auto
    tRD Phase3 Adjustment..................: Auto
    Trd2rd(Different Rank)....................: Auto
    Twr2wr(Different Rank)...................: Auto  These were already set to this, and there was no Auto << There is Auto, scroll up to the top, past one and you will see it
    
    Twr2rd(Different Rank)...................: Auto 
    Trd2wr(Same/Diff Rank)..................: Auto 
    Dimm1 Clock Skew Control...............: Auto   << kinda lost on what you set for here, there is only +100, 200 and so on.  All below Static tread should be on auto for both channels until dead last
    
    Dimm2 Clock Skew Control...............: Auto
    
    Motherboard Voltage Control
    Voltage Type.………... Manual
    CPU
    CPU Vcore….……….........................: 1.3625V (as a starting point... if you can't get to Windows, increase it... if you get to Windows then your rig dies, decrease it) << Low as you can get and be stable
    
    CPU Termination…..... 1.200V*.......: Auto (or you can manually set as 1.27-1.35V) 1.30 <<< you can try 1.2-1.28
    
    CPU PLL…………………....1.500V*.......: Auto (should be fine) << Please set to 1.5
    CPU Referen.…………....0.755V*.......: Auto
    CPU Reference2………..0.800V*.......: Auto
    
    MCH/ICH
    MCH Core…………….....1.100V...........: 1.2V << Maybe 1.15
    MCH Reference….…….0.800V...........: Auto
    MCH/DRAM Ref.…......0.900V...........: Auto
    ICH I/O……………….....1.550V............: Auto
    ICH Core…………...……1.100V............: Auto
    
    DRAM
    DRAM Voltage ……....1.800V............: 2.1V << Maybe 2.0, try after you do the above tweaking, same for MCH suggested change
