S2E - Q9550 - 2x2GB DDR3 7-7-7-20 1600Mhz - Trying to get stable 3.4Ghz OC

UPDATE IN POST #11



Hey Guys,


I've been trying to run stable on 3.4Ghz for a couple of days now and I just can't seem to find what's missing



Specs and info:
First attempt at building my own rig (went fine), water cooling it (also going very nicely ) and overclocking it (touch and go :P).

Specs:
Vista Ultimate 64Bit
Asus Striker 2 Extreme
Intel Q9550 2.83Ghz
2x2GB Corsair DDR3 XMS3 DHX PC12800 7-7-7-20
EVGA GTX 280
WD 300GB Velociraptor
Zalman ZM-1000HP

Cooling (H20):
DDC3.2
TFC 480 w/ Zalman ZM-F3 fans (idle set to ~rpm1000, load to ~1800rpm)
D-Tek Fuzion V2
EK-FC280
EK Res 250

Pictures of rig:



Temps and voltages on load (3.2Ghz - Stablish):



Bios Settings:
CPU FSB: 1505
Vcore: 1.35
Vnb: 1.5
Vsb 1.5 (Auto)
MEM FSB: 1505
Timings: 7-7-7-20
Voltage: 1.84V
(Anything not mentionned it on Auto, speedstep disabled, loadline calibration enabled)


Now I'm nearly stable on those settings at 3.2Ghz (60% pass on 10 Linpack runs). A bit of fine tuning and it should be stable.



Anyone have any tips or suggestions to push this chip a littler further?
I'm still not familiar with what the voltage settings other than Vcore, NB, SB and Mem do so I'm open to suggestions



One addition to my system I'm considering is getting an extra 40mm fan to place on the top mosfet heatsink on the Asus Fusion Block system to help keep that NB under control:




Edit: Stable on 3.2 by raising NB Voltage to 1.54, NB temp now at 59, I don't think I can push it much further without added cooling, I remember reading it gets less stable above 60C :/
