FWIW, here's my BIOS setup (402, although 401 and 254 worked fine for me too):
  • CPU Ratio: 10
  • FSB Strap: 400
  • FSB FReq: 400
  • PCIE Freq: 100
  • DRAM Freq: 1600
  • DRAM Command Rate: 2N
  • DRAM CMD/CLK Skew A/B: Auto
  • CAS Latency: 7
  • RAS to CAS Delay: 7
  • RAS Precharge Time: 7
  • RAS Activate to Precharge Time: 21
  • DRAM Static Read Control: Disabled
  • DRAM Dynamic Write Control: Disabled
  • Clock Twister: Stronger
  • Transaction Booster: 6
  • Channel A/B PH1/2 Pullin: Disabled
  • CPU Voltage: 1.3625
  • CPU GTL (0/2): 0.63
  • CPU GTL (1/3): 0.67
  • CPU PLL: 1.5
  • FSB Termination: 1.1
  • DRAM Voltage: 1.8
  • NorthBridge (VMCH): 1.31
  • NB GTL Reference: 0.67
  • SouthBridge: 1.05
  • Clock Over-Charging: 0.8
  • Load-Line Calibration: Performance (Setting to "Normal" requires CPU V=1.425 !!!)
  • CPU Spread Spectrum: Disabled
  • PCIE Spread Spectrum: Auto

I changed several of the options from "Auto" to their default or standard value, just so I would know the exact settings. Most of the above settings fall into that category.

Any advice on how to eek more FSB performance out of the memory? Although I could boot into 410 or 425, I was unable maintain Prime95 for more than a few seconds.
In your sig you say that your RAM is DDR3-1600, does that mean it is 1600 or that you are running it at 1600? Let me make myself a little clearer, my RAM is DDR3-1800 but I used to run it at 1600. That particular board is extremelly picky when it comes to supporting RAM passed 1600Mhz.
