I'm honestly short of time and have a non-bootin Phenom with a DOA board and a DOA PS for 3 days, so not in the best position to post, but to answer your qs, all has been shown many times in one place without anything extra. Me and Achim must have posted this quite a few times, all you really need to know is small, trust me. Achim did it fully incl. the bit values needed in the DFI thread, straight from the AMD guide. Check that long quoted post, it's all there. http://www.xtremesystems.org/forums/...&postcount=578

About the MSRs, they are not MB specfic. MSRs are CPU registers, held inside the CPU. When you change them, you change the CPU settings (if write enabled and within specified parameters). Thus if you have a Phenom, all the VID/FID/DID MSRs and their respective value mappings should be the same on any board. They can be found within the Family K10h BIOS and Kernel Developers Guide.

Value mappings, again, a monstrously lengthy task and can v.slightly differ from a board to another (i.e. depends on VRM - vdroop and vdrop you get) so not really feasible to write one by one, refer back to the VID/Volts I posted long ago as they denote the VID=Volts for IMC as well.

Quickly;

MSR C001_0070 decides the current system state.
ALL 96BE's can change VIDs.
95/96 are locked upwards at 1.25VIDs.

MSR C001_0070
EDX 0x0
EAX 0x28003007

Blue Bolded Hex Value = NB VID
Red Bolded Hex Value = CPU VID

That above is at 1.25VID CPU (30h) but around 1.30VID CPU NB (IMC - 28h).

Hex to NB VID

20h 1.350VID
25h 1.325VID
27h 1.312VID
28h 1.300VID
30h 1.250VID (default)
....
34h 1.225VID
35h 1.225VID
37h 1.212VID
38h 1.200VID
39h 1.200VID
40h 1.150VID
41h 1.150VID
42h 1.138VID
43h 1.138VID
44h 1.125VID
45h 1.125VID
46h 1.112VID
47h 1.112VID
48h 1.100VID
49h 1.100VID
50h 1.050VID
52h 1.038VID

That's lowest I've been at 1.8G, my Phenom cannot downclock NB so I can't try lower VIDs on NB.

Test 30h-25h NB VID please, its only a copy/paste from read to write, change NB VID number and click on write. Then check AMD Power Monitor (latest one) to let me know what value you get. Guide mentions different to what I was getting. There should be 1.275VID and a few more values I was missing.
