I have the same set up, although I use a different cooler and OCZ brand memory with the same stats. I recommend skipping the 333-399 range and going straight to 400. Set your CPU multiplier to x8 because x9 (3.6 GHz) is probably too much. DRAM should be 1:1 (i.e. 400 MHz / 800 rating). Who knows what the mobo does with "Auto" voltages, I suggest just using lowest voltage instead. I use lowest voltage for everything, except 2.0 V for RAM (it's rated for 1.9-2.1 anyway) and 1.3125V vCore. I might just have gotten a lucky chip, it being stable at 1.3125V vCore. Try 1.4 first and then drop down as you verify stability.
It's not a big deal, but I have C1E / CPU TM / Speedstep enabled. I figure it might help throttle if my CPU starts burning up or something. Also I left the Execute Bit checking on (not sure if this is called Enabled or Disabled).
For mem I use 4-4-4-12-2-35-3-9-4-10. The last 6 numbers aren't very important at all (probably less than 1% performance boost), and took me a lot of checking and time to reach. I have no idea what numbers your RAM chips will be stable with. I used the memset program to view the memory chips SPD (the default, programmed-in timing values) as a starting point. BTW, you should back off your mem settings to something like 5-5-5-5-15-6-42-11-11-11-11 until you verify CPU stability. Then start tightening memory.
Since my vCore is super low (1.3125 V) and temps are low as well (Core Temp shows 23C idle up to 45C under Orthos testing), I can probably reach 3.6 GHz stably. But I think 400 FSB is some kind of sweet spot because it's exactly where the CPU "strap" changes for this motherboard. Also, I thought 3.2 was a good blend of speed and CPU lifespan. So I left it there.
You could try 401+ x8, or 356 x9, but I wouldn't bother. Above 356 your northbirdge is highly overclocked and 370-399 will get very unstable. (When you reach 400 your motherboard changes the strap and tricks the northbridge into thinking that the CPU freq is a multiple of 333, then the northbridge is only overclocked by (400-333)/333 = 20% instead of (400-266)/266 = 50%. Things get stable again at 400.)
For stability testing, memtest86 and especially its test #5 are good for a quick check of memory settings. Then run Orthos priority 9 with Blended test to stress CPU and RAM. Run it overnight, 8 hours is plenty for verifying stability. (FYI I've never seen it reach 2 hours and then fail, if it fails it will probably do it within about an hour. )
I sometimes then run rthdribl, Orthos, Winamp (playing music), and Windiff (comparing two hard drives) to stress everything. Unfortunately rthdribl consumes a lot of CPU time, dumbing down the Orthos tests.
