Here are my settings for getting the CPU stable at 400x9:
I found that adjusting the GTLs to +50,+10 gave me 9 hours small fft stability (which I stopped), whilst anything lower or higher conked out after 8 minutes or less. This was also tested twice on each setting, so I'm now much more confident this is the correct one for me.Code:Processor: Q6600 Ai Overclock Tuner: Manual OC From CPU Level Up: Auto Ratio CMOS Setting: 9 FSB Frequency: 400 CPU Clock Skew: Normal NB Clock Skew: 400 FSB Strap to North Bridge: 266 DRAM Frequency: DDR2-1200MHz DRAM CLK Skew on Channel A1: Auto DRAM CLK Skew on Channel A2: Auto DRAM CLK Skew on Channel B1: Auto DRAM CLK Skew on Channel B2: Auto DRAM Timing Control: Manual CAS# Latency: 5 DRAM Clocks DRAM RAS# to CAS# Delay: 5 DRAM Clocks DRAM RAS# Precharge: 5 DRAM Clocks DRAM RAS# Activate to Precharge: 15 DRAM Clocks RAS# to RAS# Delay: 3 Row Refresh Recycle Time: 50 DRAM Clocks Write Recovery Time: 5 Read to Precharge Time: 3 Read to Write Delay (S/D): 8 Write to Read Delay (S): 3 Write to Read Delay (D): 5 Read to Read Delay (S): 4 Read to Read Delay (D): 6 Write to Write Delay (S): 4 Write to Write Delay (D): 6 Write to PRE Delay: 11 Read to PRE Delay: 5 PRE to PRE Delay: 1 All PRE to ACT Delay: 5 All PRE to REF Delay: 5 DRAM Static Read Control: Disabled DRAM Read Training: Disabled MEM.

I've now pushed up to 405x9 which is pushing my memory a little more, but I know it's stable up to 1233 so hopefully I can begin to encroach on my old 410x9 on 1.4625v setting I had on the P5B.. At least I'm close, with faster memory speeds
So far 405x9 failed on the 4th core (which I know is weakest) with the same vcore, so am currently testing with 1.45v which has improved so far.
410x9 is still crapping out on me even at 1.5v so I would ask for any suggestions on how to approach this speed.
