December 23, 201114 yr Crew 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... Edited December 23, 201114 yr by stummerwinter
December 26, 201114 yr I usually put the thermal on the GPU (and not on the pot)... Will try this way,.. Thanks for share
