Voltage control GTX580 Lightning Extreme?


Recommended Posts

Did you switched to LN2 BIOS ?



I didn't have lightning X version , but it should be same as 1.5GB. First double switch from right should boost vGPU and vMem 0.1 Volt, try them. Did you measure voltage with multimeter under gpu load ? Turn all switches On but don't stay on full load for long time.


Southerner switch (near PCI-E slot) is for cold-bug , I don't think that should be necessary to be On. (Num 1 = on : -80C , Num 1+2 = on : -180C)
