Hi,
1) This is a known bug due to how the ring bus is configured (Vcore supplies both the core and ring domains). This should be patched soon.
2) See above.
3) If it's stable in daily use, no reason not to use it.
4) It's not that clear cut because it depends on what the default load voltage is when using offset mode. By setting the Adaptive voltage, you're at least limiting the maximum VID (for a given ratio) to something lower than the default offset voltage (as you increase the CPU ratio, you will see a disparity). If the default (full load) offset voltage is a lot higher than your CPU needs for stability, you'd have to apply a suitably large offset to reduce it. As the offset affects the entire VID stack, a larger value can cause issues for some CPUs when they transition from idle to load state.

Thanks for the detailed response Raja.
So ideally, when the patch comes, I should be able to set 1.22 as the adaptive voltage with no offset? This will tell the motherboard to supply a max voltage of 1.22 to the CPU at the turbo multiplier (4.8 ghz in my case). All other multipliers will be given voltages automatically as if no overclock had been applied. Correct?
OR do I still have to keep the voltage at 1.28 since its the default load voltage for 4.8ghz and apply the negative offset? If that's the case, I suppose I still don't see any advantage to using offset. Negative offset is still being applied to all clocks and it's just offset mode with a different label in my mind.
Thanks again!

adaptive mode works just fine on my asus x hero settings are 5.0 ghz all cores adaptive mode 1.32v , cache 4.6 ghz ( i left min cache alone as it adds volts to cpu ) ram @ 4000 cl 18 . svid support on and best case cinario and llc ia load line to the same as yours .
my cpu drops down to 0.800mhz and 0.7v idol and ramps to 5 ghz on load . my cache also down clocks when not doing much .
the anomaly i found is that when u set cache min value and max value cpu wont down volt properly . it will down volt properly if u only type in your max cahe frequency mine 4.6 - 4.7 then everything works right .
when using prime 95 with my settings my 1.32v jumps to 1.33 and once ina blue moon to 1.34v for a mill a second . bu thats from me using load line @ level 6 .
when i play games i use max performance windows power plan and when on desk top i set max cpu speed via windows power plan to 2.0 ghz unless im in a game save a ton of power . everything down clocks and under volts perfectly . when i set power plan to cpu max to 60 % i get 2.4 ghz max speed with 0.9 v max voltage . off set mode is bad news always over shoots adaptive is where its @

I tried just setting the max cpu core cache ratio to 4.5 and leaving the min at default. However, I can not get the voltage to go to 1.22 while using adaptive voltage. It refuses to go below 1.28 with llc at level 6 or 1.26 with llc at level 5.
And you say that adaptive is where it at but i still see no difference between adaptive mode and offset mode if you have to use an offset with adaptive mode. You're setting the Total Additional CPU core voltage to where you want, but if that voltage is lower than the default load voltage of your chip for that multiplier you have to use an offset to bring it down to where it should be. I could set that value to anything, but its not going to EVER go lower than 1.28 for me which is the default load voltage UNLESS you use an offset. That offset is applied to all clocks so there is no difference between what that does and what offset mode does.
Sorry if I'm being thick, but I'm having trouble understanding how adaptive is at all beneficial if you are trying to lower the voltage for your OC below the VID of that multiplier.

1) No. The minimum adaptive voltage for a given ratio is defined by the CPU. To go below that value, you need a negative offset. Negative offsets currently do not work, and that's what's being patched. I have an alpha build for the Apex that fixes this, will be rolled out to other boards soon (I hope).
2) Consider this:
My CPU at 49X defaults to 1.33V for Vcore if I use a pure offset mode and the system is under full load.
If I use adaptive, the minimum voltage for the 49X ratio is 1.28V.
If the CPU is stable at 1.22V, I need a negative offset of 0.06V with adaptive voltage, yet I need to use 0.09V with offset.
Therein lies the rub. Offset often defaults to a higher default than the minimum adaptive voltage. Granted, both may work in practice, but, some CPUs have a larger disparity, and when that happens, you need a larger offset to reduce the voltage to the desired value (which can cause a few side effects). Of course, at the same offset and load voltage values, there's no difference between both modes. At higher CPU ratios (if some offset voltage must be used) the disparity usually favors use of adaptive mode.
This should clear up the confusion.
