ASUS AMD Beta BIOS Releases

[zanzabar]

CPB mode appears to be a core performance boost, it throttles the multi and voltage of idle cores on X6 CPU's, it drops the cores to 800mhz and lower voltage a sort of power saving feature I suppose, that's as far as I have got so far I'm probably wrong lol, no notable difference in performance so far.

no desktop boards support core independent cool and quiet fully since they can only deliver 1 voltage but the bios and cool and quiet let the cpu think that it can work so it will show a changed multi and VID but the voltage dose not change. this was a huge problem with the thulbans on am3.

One would think that but the board already does that anyways.
I have no idea what the cpu cpb mode does.

I don't know about independant core voltages.
But I do know it will idle down to the lowest vid voltage when the core fid's are within the limits and etc.


Lowest fid on the ch4f by default is 4x.
At 200mhz fsb the lowest pstate speed is 800mhz.
And your highest is either the value of your cpu multiplier that you set in the bios or the turbo multiplier.
The speeds themselves are independent of each other.
Any one of them for example can hit turbo mode, and all of them can doit at once.

The only thing that the am3 can't do is cpu-nb voltages and speeds for each core independently, probably because they share the same mem controller setup.
And I have no idea if the am3+ does that anyway.
There isn't really anything to add for power management.
Unless it's bios interface wise (fid/vid control for all multi's...).

Chipset wise I've seen at least one 890fx paired with an am3+ socket already.
And then supposed new board rev's from msi I think it was.
I'm not to hopeful because of the cpu socket thing, but otherwise I don't know why not.
Regardless this bios didn't add cpu support, they usually don't add cpu support anyways until around the time the cpu is released I think.


I did notice the mem bandwith sucks at a cpu 100% llc setting .
Not sure if the previous did that, but the one before that didn't...(before 50% was an option)
It's alot slower, at least 3-5k on copy bandwith in aida64.

At a 50% setting it's fine though as far as I could tell.
I wonder if cpu-vdda would fix that :\ ?
