i7920/ASUS R2E Super Pi Test

I was just playing around with this new CPU.
I had an i7 920 C0 before but recently changed it and obviously got a D0. There is a big difference between the revisions.

My old C0 did 3.8GHz with 1.375v and 4GHz with 1.42v aprox.
Max BCLK was 195 (too poor).

This new D0 does 3.8GHz with 1.2v and 4GHz with 1.24v (3 hr Prime95 and OCCT stable). I´m trying max BCLK but it seems I reached a wall around 217-218.

- CPU Intel i7 920
- Motherboard ASUS Rampage II Extreme X58
- Memory Kingston Hyper 3x1GB
- Thermalright 120 Extreme black (2 fans)
- Antec Signature 850 watts

Other hardware stuff here isn´t important for my goal.
I´m trying for 220 but seems like the CPU won´t allow it. Here some SuperPi with a very bad time and 0 tweaking on Win 7 x64:

Voltage/temps details are shown there. Any sugestions to get some extra clocks on BCLK are well-welcomed.

That's impressive... and makes me feel bad about owning to original i7-920's.

Time to change your CPUs Olin

Increasing Voltage gave me 1 clock more but nothing else
My 32M seems to be rather slow. I think I can shave 10 seconds easily but I´m still aiming on BCLK.
