Following quote is as much documentation you will ever need, and that I ever had on that topic.

The technical reason is that memory controller is powered at Vqpi and it is physically connected to RAM.

To avoid that Vram comes back to IMC, destroying it, there are protection diodes that block the Vram voltage.

If the difference between Vqpi and Vram is less than 0.47 V, the diodes are closed but over 0.47 V the junction opens and Vram can go to IMC, destroying it.


If you want to use Vram over 1.65 V, the trick is to push Vqpi to mantain Vram>Vqpi difference less than 0.47 V.
Thanks Brama! Precise, concise and understandable.

Also, have any of you managed to get a stable 5GHz+ OC run in LinX for the stability club? Is anyone trying - other than myself.

Thanks
When you set in BIOS to 1.65V it is actualy set to 1.65625 or similar, so it's over 1.65 and they (Asus) are just warning you that if you kill you CPU, it's not their responsibility.

There are two Gulftowns in Intel 4.5GHz & 5GHz LinX Stable Club, but picture is there only for one and the other is missing. There is one Bloomfield over 5GHz too.

I would try do 5GHz LinX stable, if I had phase change unit (read: money to spend one one )
