MSI NX7900GTO T2D512E is 7900GTX?!

I haven't seen anyone clock 900 on these mems yet... but if it's 1.1ns then why not?
It should do 900 right?

No chance of that, not without a volt mod. They physically reworked the cards. The memory maybe 1.1 ns Samsung GDDR3, but with 1.4 ns timings and voltage (1.9V).

My MSI7900GTO overclocks the memory to only 1638 when Atitool crash but the timmings looks tighter than samsung specifications (batch BJ11):

trc: 31 (35) trcdrd: 10 (12)
Trfc: 39 (45) trcdwr: 6 (8)
tras: 22 (25) trrd: 10 (8)
trp: 9 (10)

in the link above we can read that the timmings of my GTO are the one used for the BC14 which run at 1400 Mhz

I wonder if relaxing the timmings can give 1800 Mhz as the 1.1 ns samsung volts specificatios are 2.0 v +/- 0.1

could anybody post the details timmings of a 7900GTX using Nibitor????
