Can't overclock my Q6600 past 2.7Ghz

Affirmative

Set your NB voltage between 1.30 and 1.40
Set Vcore arround 1.30
Set SB arround 1.50 (or other settings(not familiar with EVGA))
Set HT to arround 1.30 (not familiar)
Then multiplier 9X
FSB 333 X 4 = 1333Mhz
Core speed = 3.0Ghz

Ok, i see you are also using 750I SLI, normally they have the same Chipset, Northbridge and Southbridge
I got my Q6600 (VID 1.325) stable at 3.0Ghz

These settings should work for you

NB 1.30
SB 1.50
HT 1.30
Vcore 1.325 (or 1.30 if you have a lower VID)
MEM AUTO (or default voltage of your ram, every ram has another voltaege f.e. Kingston : 1.850, OCZ 2.1V, ....)

Rated FSB 1333Mhz
333 Mhz X 4
Unlinked
Ram 1066Mhz (Ratio 8:5)
Memory Timings Auto

I hope this settings work for your 750I motherboard
I am not familiar with EVGA, so don't kill me if the settings don't work

hi i have the same problem my q6600 is in a nf650islit-a motherboard and the only way i can overclock is by the fsb and any thing over 2.7GHz and it jst becomes unstable and crashes
my multiplier is 9
core voltage is 1.27500v
