Getting ready I see:). U might wanna cover more of the pcb with more LET. When benching 580 with ln2 it froze almost all the way out to the ends. Dont wanna see U ******* up Ur card becouse of condensation...

To be honest Im not sure if U can control voltage from a software on that card. U might need to do a hardmod.

But try out AB or gpu tool and see. Make sure to enable voltage controll and overclocking in options in ab. might need to change settings in cfg file.

mine stopped around there also.. i need to buy some supplies before modding this more. where did you get extra caps? same rating absolutely necessary?
sorry sort of new, and trying to learn fast. (also going to try and make external vrm as soon as supplies comes biggrin.gif)

stock VRM's are not the issue... stock Inductors are ;)

 

 

 *I used some Panasonic polymer caps.. 150uf, rated for 2.4v or something like this.. There are 4x locations you can install them on either side of the PCB.. same as in my pic. Adding caps to the vmem phases helps lots as well.. my mems are good on air to ~1160mhz, once the card is cold they scale well with just a slight voltage bump.

 

helpful info for capping:

 

GPUv caps - 2.5 or 4v .. high Q typically 400-800uf

vMEM caps - 4v or 6.3v .. med Q typically a bit larger.. 600-1800uf work well

+12v GPU input caps - 16v .. med Q typically a bit larger.. 1000-3500uf work well
