Don't forget that he didn't use HT and use some really cold water.

Initial indication is HT on for 32nm doesn't cause as much heat as it did for 45.

Also - droping from ~1.65 down to 1.45vcore, that combined with the 32nm part already runing cooler vs. the 45 - the 2xboreas is working out great.
A little antifreeze keeps the water from freezing.
When summer comes I will need to be carefull about condensation - I haven't really protected anything in my current setup.

But it does make the chip not clock as high when enabled, which I think was his point.

Yes, was true for 45nm, probably also true for 32.
When I get a chance, I will rerun with HT on and see how far I get - probably not 4.7 but we'll see.

my 4.6 ghz is with HT enable. will try 4.7 this weekend.

Ok so this time with HT on, I probably didn't need 1.5v vcore but I didn't want to spend a lot of time at high voltage to find the lowest v.
Cooling was the same 2x boreas in series to an apogee XT block.
I might try to up my pcmark vantage score this weekend.
Gflops must be broken.
