Preparation ASUS GTX580 MATRIX for LN2

[stummerwinter]

As Massman requested few days ago I will show here, how I prepare a MATRIX for LN2...

First I use an organic rubber to isolate the PCB. This material is easy to release from the VGA, much easier compared to ARMAFLEX...

In the next step I heat up the container to arround 50°C for easy application of the GOX, normaly to stripes like shown...

...and then equal out the paste:

For backplate I use a 6 mm hard platic coverd with two layers of 3 mm ARMAFLEX:

Fixed with springs, needs some space, but works, add some plasticine to isolate:

Board is isolated with ARMAFLEX:

In addition I add a CORASIR mouse pad (any will work, seems to bee out of neoprene):

Everything together:

After 3 h beniching @ -175°C, no issues this time, but no better score, this card could do only 1525/1350 UH:

In addition:

- use the hack-fw to adjust voltages to 1,5 V - hack 8 works normally fine
- swith 2D-mode off, eg with GPU-tweakit
- adjust voltages with NVinspector to 1,6 V or higher in combination with buttons
- use no-cold-slow bios
- bench

Some cards need to heat up to -120°C to boot into OS, in this case a strong hair dryer or something similar helps...

Have fun...:)

I usually put the thermal on the GPU (and not on the pot)...
Will try this way,..
Thanks for share
