Does anyone have anything to report in on with the 12/21/07 & 1/03/08 Beta Bios Findings?

Hello, 01/03/08 bios allowed me tighter memory sub-timings and max 260 ref clock over the 12/21 bios, which i could not get to post above ~252. Also, I can approach 2100mhz NB but not stable above 2000mhz no matter what voltage, 12/21 bios would not post above 2000mhz

This is my current highest stable overclock with 1/3/08 bios (prime95 8+ hours stable, no experienced lock-ups):
246 ref
phenom 9500 @ 2706 1.38125v (1.376v load), cpu-nb volt = 1.2v (default)
crucial ballistix pc2-8500 5-5-5-16 @ 492mhz 2.16v (1:2)
nb+ht @ 1968mhz 1.25v (default) (8x)
pcie @ 104 1.12v (default)
ref clock adjust gap @ 2 (<--- can i get an explanation on this setting please)

gives 12412 nuclearus, 21m20s project 2653 frame times running 2 smp clients for ~2377ppd

a stable 280+ ref clock is desired !! hope dfi can make this happen
