The 8GHZ Project U.S.A.

Hmmmm very interesting. Koolance cooling is plenty capable of 4GHz, but at some point the blocks can't transfer heat fast enough.

Yep, probably have the volt mod set up already. I'll keep checking back to see what kind of progress you make. Good luck!

i can get a 631 up to 5.3ghz on air cooling.. so heat definitely shouldn't be that much of an issue with water...

Our experience with ES chips leads me to believe that the IHS mounting process isn't perfected until around the production of the Retail chip. If your lucky the thermal resistance on your ES should not be as bad as ours. As this is the worst case we have come across to date.
with a stock frequency of 3GHZ and the Vcore at 1.6v The Koolance CPU 305 Block temp was 24C and the IHS was 27C but the Die temp was still 76-82C! the removal of the IHS should solve the temperature differential.
We saw very similar readings with the Koolance CPU 300, Intel Boxed cooler, and the Zalman 9500Cu.

I'm currently in the process of removing Dielectric grease from motherboard and will test the Voltage Temperature curve once again with Air, Water, Chilled water, Phase, and LN2 will be last.

Why is the ln2 pot so damn tall? You could cut about 2 feet off...

We are looking at having a 2" diameter cylinder of copper milled to our specifications for Direct Die cooling.
Most of what has been built was to get the LN2 on the chip and see what was going to happen at -196C
we had two 12" copper tubes some couplings and a few P4 boxed coolers laying around so we put them to good use. The copper cylinder in the P4 Boxed cooler just happens to be the right sice for direct Die cooling with a LGA775 socket.

like Gautam sayd the tube looks like it has been in WW2 or something like that !
if u veel hot with 1.4vcore u should give a run @ 2vcore , it seems u guys have te hard-ware and the helpings hand .
but if i have to say what i think i dont see this happen really , thouge i wish u guys the best off luck

At 1.7vcore With the IHS and LN2 we saw -75c on the back of the board
More surface area in the LN2 block is definitely needed.
For NON OC testing it worked rather well considering it cost us absolutely no $$$$ to make thanks to Intel!

You should just go to the pro's, call up kingpin, mickeymouse, or gorrilakos and get the best 3" tubes ever made from any of them...

Also, why do you have an AMD chip with the IHS pulled?

And BTW, the IHS on all intel chips sucks, not just the ES ones.

Intel ES just happen to have some of the worst mounts around :P

When i get a lil more time this week ill see if Kingpin could loan us some of his knowledge his name was first in my mind when I began this project.

We pulled the IHS off the Opty for testing on a swifttec Rev 1 Storm.
