Need help, q9400 overclocking

Hey guys!
Ive been ocing for about 2 years now and im only now starting to go a bit deeper.
I have a q9400 (non S) running at 3.36ghz (418fsb, 8x multi) on my msi P43 C51 neo, 2 sets of mushkin essentials ram 2x2 1066 running 1:1 at 6 6 6 24 timing. My temps are around 35 idle, 49 heavy gaming load (didint exceed 45 under prime95, 3 tests.) Id like to reach 3.6 ghz but I need help with voltages. You see, when I try to increase my vcore it goes one step up to 1.127v, appearing white (safe settings), and the next step reads as red, unsafe settings, at 1.128v. Is it dangerous to go past this? I feel as if i could push 1.2 at least just to maintain stability but i have some concerns without a second opinion and some more information. Aswell, im curious what I should set vtt to. Thanks in advance!

Maximum safe vCore voltage is 1.45v according to Intel but I've run greater than that for over 10 years. Things get hard to cool above about 1.4v so make sure you have enough cooling to keep things below 90C or stability will be difficult to find. Default spec VTT voltage for 45nm chips is 1.1v and the most that many boards allow is around 1.3v.

Quads are difficult to run at high FSB which is a shame, because they can sure use it more than duals. Your goal of 450MHz is quite high and would require a lot of tinkering to accomplish, which is why most people would instead get a chip with a higher multiplier like 9x (Q9650, X5450, E5450), 9.5 (X5460) or 10 (x5470) using the 771-to-775 mod. Especially given their low prices today...

1.128v is lower than the VID of any 45nm S775 chip I have ever had hands on and that's dozens of them. Nevertheless they were all made on the same line and rated to the same max voltage--the VID was only binned to there. Note that the factory VID spec table goes all the way to 1.3625v and Intel would've had no qualms going there if only AMD had gave them any competition at all.
