**Official DFI LanParty UT 790FX-M2R Review/Overclock/Guide Thread**

What do you mean by weak and normal mode here?

Hmm.. it modifies them on all Phenoms according to guide AFAIK. What voltage and VID did it give you?
Try 0x3000100A from 1.25VID, it should give you a ~10W AC idling increase in power. If not then something with your CPU MSR is going iffy.

Voltage (in CPU-Z and Everest) did not change, AMD Power Monitor showed what I wrote into the register. The board seems to simply not use VID's. Every board seems to have it's own implementation. Must read the clock-chip's specs.

Yeah I saw it, it's very weird and well, too high

Gonna look into that tonight, happens on various power consumption's in idle so i can sort out psu efficiency jumps.

Thanks but are you sure that's their only relevance?

K, I wrote down all the registers related to P-States and power. I'll post a list here soon with all the variables.

Have you actually tried these work? Very good options if they do.

Well the resolution of the super-io chips reading seems to have a lower resolution ~0.016V, so that can not be used for verification. But I had situations where an +0.00625V helped to get the system stable.

What (&#37 Vdrop and Vdroop does the board have?

I'll give ya a few examples:

cpu frequency/bios/idle/load
200x11,5/1,1625/1,152/1,152
200x12/1,175/1,168/1,168
200x13/1,35/1,328/1,344
219x12/1,38125/1,376/1,376

200x13 might work with a lower voltage all others use the minimal possible voltage (~8hrs prime95+3dmark+internet+some cad work).
From bios to load it's in the rounding area. idle might sometimes be 0.016V lower.
