    What is the GT550M voltage?

    I pull up a 550m vgabios in nibitor and it shows up as a 540m bios with the same voltages as the 540m bios, but I can't view the clock domains like I can on the gt540m.

    So is the 550m just an overclocked 540m? It's exactly the same. Some people say they get 760Mhz max on the 550m.

    I'm on a 540m and get 800mhz from increased voltage from the gt540m/gt550m stock 3d volts of 0.98v. I increased my 540m volts to 1.0v and get 800Mhz so I'm out performing the 550m...

    I'm looking to modding over the P15 voltage table of the gt 440 which is the exact same GF108 which has a max 3d volts of 1.1v which can do 810mhz ultra stable by stock. I could possibly push to 835Mhz while retaining stability on my gt540m if I can mod over the gt 440 p15 value/ parameters.

    I'm thinking this is something that has to be done in hex because say the 0.98v parameter is at I believe 00 00 00 00 00 00 0F 00 62. But I want to retain the p15 value all together, because when I change the 62 which is 0.98 to 64 and recompile it pulls 1.00v in windows in 3d but the p15 goes away in Nibitor.

    I want the P15 to remain as it is with the new 1.1v value within...
