Q9550 and G.Skill F3-12800CL7D-4GBPI stable settings (water cooling!)
fsb450x8.5=3825Mhz
Dram 1800Mhz 8-8-8-20 Performance level 7
8 Hrs plus Prime Stable (blend), 20 runs Intel Burn Test at max stress
3DMark06 and 3DMark Vantage stable (no freezes, lock-ups or bsod).
Max CPU temp recorded were 78C using IBT and 69C with Prime. All tests backed up by pics if anyone interested.
Warning - These settings are for water cooled cpu and NB.

Next step is 471x8.5 stable (to break the 4Ghz barrier for a cheap quad CPU!) with the g.skills limited to 1570 as there is no way they will work above 1800 Mhz (will need better memory for that - wish I had the corsairs :D).
