Testing components:
AMD Phenom II 940 BE Retail.
Gigabyte GA-MA790GP-DS4H
2x1gb Team Xtreem PC8000
Gigabyte ODIN Pro 1200w PSU
Gigabyte HD 4850 and XFX GTX 280

Air cooling: Thermalright Ultra-120 original
Single Stage: Built by me, chilly1 evap
LN2: Dragon Evo 2.4



The cooler I won't be using.

What I'll be using instead.

Some quick air results...
4ghz was doable, but not for anything multithreaded.

Prepped for subzero cooling...
Very easy to make gaskets for this board.
I put electrical tape over the inner RAM slots after the first LN2 run because they were freezing over.

Brief Single Stage testing...

LN2 testing...
Unfortunately, going into this I only had about 5 liters left in my dewar.
When I ran out was at 99% of a wprime 1024m run at just over 5.6ghz.
I'll be back with more.

And the benchmarks for the onboard video...

very nice OC dude.

my next jump should be into LGA1366....but viewing the power of the Phenom II (and the price), maybe I'll jump with AMD again.
