Are you talking about the contents of this thread? -> http://www.overclock.net/t/1321511/gtx-680-lightning-vgpu-mod
Not an extreme cooler here, but just curious as to what your asking about would do, and what can be done with the .zip file you posted in that thread.
No not talking about that thread... which was referring to a possible OCP mod for extreme users by flashing the CHiL firmware [such as GTX480]. I confirmed with MSI sources that this is not needed with Lightning series, so long as you use LN BIOS. MSI has set OCP limit to 1000A for GPUv ... effectively 'removing' OCP for the core.
What I am asking in this thread is "who wants to test memory OCP mod for extreme mem voltage/speed?"
