Intel Dothan Overclocking, going for 100% OC on Dry Ice

Overclocking/Overclocking Tests by Jort @ 2005-06-29

Today we go for a 100% overclock with a 1.6Ghz Pentium M Dothan CPU, using Dry Ice to cool the CPU this might be possible. To make things more interesting we also push an ATI X800 to its limit running it at -52?C.

Installation

Asus P4C800-E Deluxe rev; 1.03 featuring a vdroop mod, vcore mod and kyosen vdimm mod, in short, ready for over-volted action.

The Asus CT-479 adaptor with Dothan installed and a thin layer of white thermal grease applied

After we installed the CT-497 we insulated and covered it with non-conductive grease or for the Dutch people “Vaseline”

The motherboard was insulated with multiple layers of insulation or closed sell foam, first the backside of between the back plate and motherboard, then between the motherboard and the retention bracket.

Then inside the retention bracket and the CPU socket, then the CT-497 on top of that insulation, then greased the adaptor with the non-conductive grease.

When you install the adaptor the socket leaver is down you have some place, put some foam there too.

Let’s hope there will be no condensation after having taken all these precautions

I also placed some Armaflex insulation around the container’ base so air can’t get to it.

Now the motherboard is ready for the installation of the container onto the CPU, before you do you can make a CPU shim of some layers of paper or some small pieces of foam.

This is to prevent cracking this fragile core of the cpu.

During one of the first runs I noticed some condensation forming around the edges of the hold down, so I wrapped it in some paper.

Finally ready for the first tests, a cheap old-timer TNT2 was used as graphics card, it once was a very capable card….

Let’s bring on the Dry Ice ->
