First off, it could just be the use of a Beta BIOS. I see you have to use one so you may be out of luck until a non beta is posted. But just had to tell you that because EVERY beta I have used caused me ram errors. You could try F8a, it supports 8400 as well, as does F8f, but then again all three being beta could give you ram errors
I would keep the voltage to 2.1 or less unless you have a Fan on the ram, as for MCH you may need .125 or .15 for 4 sticks, so try that as well. As you have read, I personally think GA and crucial have issues, but some disagree and get them working fine, Lets see if we can for you.
Try these settings >>>

Fine CPU Clock Ratio 0.0
CPU Frequency 333x9
CPU Host Clock Control [Enabled]
x CPU Host Frequency (Mhz)
333 << manually set to 333
PCI Express Frequency (Mhz) 100
C.I.A.2 Disabled

Set to the highest value below, then later you can move them lower ONE AT A TIME testing after each move

Here is/was likely also you main issue I saw >>>

Static tRead Value Auto=6

You cannot use a phase adjust value with 6, as it will make tread value run at 5 most of the time. I doubt you will even get 4 sticks to run with a tRead value of 6, so best to use 7 or above and do not use a value AT ALL for phase adjust
