    i7 920 3836A756 #2
    Max BClock

    Testing 2nd twin batch cpu and definitely this second i7 920 3836A756 is better than my first one in terms of max Bclock and low CPU VTT usage.

    i7 920 3836A756 #1
    • max memtest86+ bootable bclk = 224 requiring 1.58-1.60v CPU VTT
    • max super pi 32m bclk = 222bclk (without IOH/ICH voltage tweaks) & 228bclk (with IOH/ICH voltage tweaks) requiring 1.60-1.61v CPU VTT
    • max CPUZ Validation = 230bclk requiring 1.60-1.63v CPU VTT


    i7 920 3836A756 #2
    • max memtest86+ bootable bclk = 229bclk requiring 1.40-1.48v CPU VTT
    • max super pi 32m bclk = 227bclk (without IOH/ICH voltage tweaks) & ???bclk (with IOH/ICH voltage tweaks TBD) requiring 1.48-1.50v CPU VTT
    • max CPUZ Validation = 231bclk requiring 1.50v CPU VTT


    TBD - Haven't tested 2nd cpu with IOH/ICH tweaks yet

    Max Validation @231Bclock

    CPU VTT = 1.50v





    Max Screenshot @228Bclk with low CPU VTT



    Max 32M @225Bclk



    Bit higher at same CPU VTT = 1.48 = 227Bclk
