If I have all of the subtimings set manually and I can boot with 102.54 BCLK and 26.00 multi (2666 effective), I should have no issue booting at 100x26.66, correct?

 

Because that's not what's happening. I can't boot with a multiplier higher than 26.00. BIOS F6C.

 

EDIT: Booting at 106x26.00 for 2756 effective... but I still can't even boot at 100x26.66.

 

EDIT 2: Pushed as far as I could in Windows... 109.5x26.00 = 2850. Of course when it froze, it caused a cold boot. It wouldn't even boot at 105x26.00 anymore. To get there, I had to start with the BCLK low and slowly make my way up (101x26, 102x26, 103x26, etc.).

 

Here is the full array of settings. Everything is quite loose:

 

BCLK 100

CPU Multi 35

CPU Speed 2500

Memory Multi 26

Memory Speed 2600

CPU Vcore 1.35

CPU VTT 1.15

CPU PLL Auto

IMC 1.15

DRAM Voltage 1.65
