    @All: thanx!

     

    @Hondaycity: no, full pot is to much, because off danger that thermal paste breaks...

     

    @Smoke: no, my own design, saddly to expensive to manufacture, need a wire EDM machine

     

    Have a 100 mm wide (~ 2,5 kg) und 80 mm wide (~ 2,0 kg) version, the big is a little tricky with the MATRIX, because very close to power management, but works somehow, used it this time for 03, normally prefer for 03 and 11 the slim one...

     

    100 mm:

    @1700: if I can solve the problem with thermal paste, this card has the potential...;)

    Preparation ASUS GTX580 MATRIX for LN2

    in Extreme overclocking

    Posted · Edited by 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...:)
