Question : New question for you.
I plan to buy the Gigabyte GA-990FXA-UD3 or
Gigabyte GA-990XA-UD3 motherboard but I see lots of people having CPU vdroop issues.
Why is this so and what is being done to fix it?

Answer : Hi,

"GIGABYTE 990 series motherboards strictly follow the AMD AM3+ load line calibration design guide, and so CPU

V-core voltage will drop according to loading. Such calibrations are built into the platform to protect the user’s purchase

and prevent damage to the PC system."

sounds like they just being lazy.

they should add the LLC option in the bios, to let the user choose how much LLC is used.

the lower the LLC the more vdoop there is, higher the LLC the less vdoop there is,

At the moment I use Gigabyte GA-890XA-UD3 with a Phenom II x2 560 BE.
I just changed to the most recent bios and now CPU volts show and stay at 1.34v instead of what it shows as default in the bios(1.35v).
Before with the other bios it showed and was 1.35v all the time.
I got used to the voltage changing under load.

but the gigabyte 990fxa boards handles x2/x4 chips fine without vdroop .

the problem is with the x6 chips it doesn't seem to handle the voltage right. it needs more LLC
