Thank god work is being done on memory compatibility.....right now it is SHOCKING.

890GPA-UD3H with Athlon x2 5200+ and F3-12800CL7D-8GBXH ram gave 3.95GHz on unlocked cpu (became x4 with L3 cache) and 1800MHz ram speed.

GA-990FXA-UD3 with same cpu and ram is unstable when unlocked cpu, and even when cpu is locked ram can't make rated speed at rated timings and cpu only stable at 3.4GHz. Ram always wants to run at silly loose timings.

@dinos22 or Sin0822 i have two questions since you seem to be in the know with gigabyte;

Are there any indications that modules can be unlocked on these FX just like cores on Phenom?

I have a Rev1.0 990FXA-UD3 that has very crackly sound from the onboard 3.5mm jacks and popping from HDMI......is this a known issue and maybe down to drivers for the dolby realtek chip or have i just got a broken board?
