So it looks like instead of actually fixing the issue they just used some lame-ass hack to fix it when it happens. This is totally unacceptable (not to mention the on board Realtek sucks major you know what...) and makes me wish I went with Asus like I usually do...
UD7 shows less RAM when it is unstable (at least it did in good old days I used it). Loosen up the timing, or add Vdimm to get it stable, and it will show/use all RAM.
