7900GT Overclocking Help Please - Off the scale

[M@tt]

Hello Guys, I wonder if anyone can help please :)

I have installed CoolBits Reg, but have reached the end of the scale in Memory overclocking without any errors at all in 3Dmark 2005, so I would like to up the memory some more to find the limits.

How do I increase the mem scale please?
