Chip limit?

[Platinum]

Ive got my 2500M up to just over 2.7GHz but I feel there may be more there
Its running 1.95v, I think it will do this speed with less volts, I can boot into windows at up to 2.8GHz but it falls over, Also I can only get the FSB up to 210MHz, seems low for a NF7s V2?
Yes 2.7 is very fast but if theres more in the chip I want it
System specs are as follows :

Custom waterchill setup, dual rads (1 120mm rad and 1 dual 120mm rad) antarctica waterblock, nb block, L30 pump
Antec 550 Watt True power
2500M
NF7S
1gb PC 4000 Kingston HyperX
6800GT
3 hard drives
Optical drive
Shed loads of fans and cathodes

So what do you think? is there any tips for getting more speed? Ive heard of a L12 mod?

Good effort mate, not tried mine above 2.6 cos it scared me. What cooling are you using with that?

I got mine to 2590mhz on air @ 53'c and 1.85v remember the nf7s tends to under volt so 1.9 may = 1.85
