Memory/NB Cooling?

[[XC] gomeler]

Anyone ever phase change cool memory or the north bridge of a nforce2? Considering how electrical circuits start to take on superconducting capabilities with lower temps, would below zero temps help? More curious about the possibilities than actually doing this. Would be so xtreme though =)

superconducting is not just a matter of temperature, its a matter of material.
afaik the team from THG cooled the NB with a direct die while they OCed the P4 using LN2...

Peltier cooling the Northbridge on a DFI NF2 to -20C gave me a ~5MHz increase in FSB with 2-2-2-11 timings increasing from ~260MHz to ~265MHz. This was with the same voltage applied to the northbridge and memory.

This has nothing to do with superconducting

I ran watercooling on my NB of my A7N8X Deluxe (NF2) to run FSB @200. I got sick of the plumbing and recently removed it after my experiments with my first water chiller.

It simply doesn't need any cooling. Other than the stock puny heatsink. My system is stable:

2500M @ 2200 200FSB 1.6V (lowest on the MB)
Dual Channel 2x512MB Corsair XMS PC2700 2-3-3-6 @ 2.5-3-3-6 default voltage 200FSB

And not a single fan in the system. Ambient in the case can go into the 30s (C).

ive phase changed my northbridge with my vapochill once .. (nforce2 a7n8x e deluxe)
CPU runned @ r404modded Mach1

it didnt get me really any further in OC ..
but everything runned more stable and i had no crashes anymore (like they were before .. even if very seldom)

but its cool to have 2 (or more) cooling units connected @ one PC

I know the jpas LN2 cool their nb and ram, just cant find a pic of both. Heres one of the nb I think

Edit:
Found it

I've been thinking about how to phase change the RAM for a while now, and I've got some ideas on the evap. Insulation is going to be a though, so I was thinking of connecting the suction line from the GPU evap (dual evap system, no point wasting a 1/4hp Aspera) to two RAM evaps and then connecting a final suction line between them and the compressor. Not only should it give atleast -10 on the RAM, but if the other evap is sitting on something with a low heat output (GPU) the RAM evap would end up acting like an accumulator and help prevent liquid slogging.

Hmmm good point on the material, but I would think something would be helped by cooling the ram. I run OCZ Plat rev2 3200 @ 2-2-2-5 @ 210 (I'm not pushing it, mobo has a crappy controller) and when it is under full load they are too hot to touch, so now they have a 80mm sitting over them. I can only imagine how hot these dimms will get @ 300+ ~3-3-3-7 or whatever timings it requires to run that high. If anything perhaps I can tune a system that runs the suction line from the CPU over a combined heatsink on the ram, bringing tems into the ~30-40 *C
