The Maximus Formula Thread - Help/OCing/Guide/Rampage conversion

[Brama]

Just got my Asus Rampage Formula yesterday (no maximus -> rampage conversion.)
It had BIOS version 0219 ready. Voltages seem to be bit strange (Dram voltage set 2.1 in bios, reads 2.192 in bios; cpu voltage set 1.38125, reads 1.360 in bios ?).
Can anyone comment those voltage readings?

My P5E converted to Rampage does the same.
Actually, to have 2.1 V BIOS sensor reading, I have to set 2.02 V.
Cpu voltage is normal because if you don't enable LLC, the BIOS apply a minus offset to the preset voltage, following Intel best practice in designing a VRM for core2 processors.

Loadline Calibration was turned on when I looked at the voltages though

The vDRAM is a normal overvolt. A lot of ASUS boards do that, and the Maximusi were no exception, so it surprises me not in the least that Rampages would do the same. Just be aware of it and undervolt where necessary.

Your CPU undervolt seems odd. I have no comment regarding it besides that.

Loadline calibration helps with vdroop (the drop while under load) and not the vdrop which is the undervolt I've seen on every board I've owned. I have mine set 1.30v in bios and get 1.28v real. I also have the vdroop pencil mod and the voltage doesn't budge under load.

Loadline calibration never seemed to do anything for me so I left it off. Pencil mod works much better.

btw this is with P5E -> Rampage
