ground1556 - Rampage II Extreme @ 280MHz - 279.99 MHz Reference Frequency

Killer board. If you don't want I do ;-)

Pretty sure @Jokot has a better one, might send him one of the CPUs I ran the next couple weeks to do more testing. The x58a-oc I have on hand currently is a little worse at ambient, but can boot significantly higher PCIe clocks as well as more BCLK. I suspect thats the only reason it got further then the Rampage II here. Not sure when I'll get around more testing. Need more boards to compare

Other scores from that session:

E5640 - 863 cb (R15); highest quad core score on the platform. Limited by time, CPU wasn't maxed out sadly
E5640 - 5836.16 MHz - limited by board and CPU not playing well if upping BCLK in OS. x58a-oc got wet before I could go for a max frequency run there.
E5649 - 1251 cb (R15); highest non-LN2'ed six core score on the platform. Limited by the board and CPU-z bugging out. CPU does 280 BCLK on Dice, so with the right board more is certainly possible.
x58a-oc - 287.22 MHz - CPU, me or board limited, not quite sure. I suspect the board because it handled far worse at ambient the the Rampage II (~2% worse). Gonna pick up more boards to confirm. Just as the last one I ran this one can't run the E5606, my best CPU for maxing BCLK
 

Also spent about 2 hours getting my good w3520 to run properly, but it only caused troubles. Gonna need to try that one again.

In your experience ,what is the most important for reaching max fsb on certain cpu/board ?

How do you know which one of them you maxed out,cpu or mobo ?

All my binning data is here (needs to be cleaned up, haven't updated the starting post in a while), but in short the following things appear relevant (as far as I can tell):

1 - max BCLK the CPU can handle
2 - max PCIe clock the board can handle
3 - max PCIe clock the board can boot
4 - max BCLK the board can handle
5 - max BCLK the board can boot
6 - temperature
7 - "baseline" BCLK of the board. Requires a CPU tested with as many different boards as possible. Tested at ambient lacking cold for some boards.

In these cases I had these:

x58a-oc:
1 - >=287 (unknown)
2 - 138
3 - 132
4 - >=287 (unknown)
5 - >=286 (unknown)
6 - dice temps with MX2, currently don't have a probe, guess -60°C?
7 - 266 (98.6%)

Rampage II Extreme:
1 - >280 (ran 283 before the x58a-oc got wet)
2 - 138
3 - 118 (this is what I expect to be the limiting factor here, together with #6)
4 - >=285 (E5606 did this much, but the valids failed sadly)
5 - 261
6 - dice temps with MX2, currently don't have a probe, guess -60°C?
7 - 269.65 (100%) (main reason I was hopeful in this board, sadly failed me)

EX58-UD3R:
1 - >280
2 - 125
3 - 126
4 - <286 
5 - <286
6 - ambient ~20°C
7 - 267.3 (99.1%)

Best 5 CPUs on "baseline board" Rampage II at ambient:

E5606 - 273.6
E5640 - 273
E5649 - 269.65
E5640 - 265
E5606 - 264
