Thanks for the reply.
From Bios:
CPU Voltage: 1.176V
DIMM Voltage: 1.524V
VTT Voltage: 1.044V
Is it possible CPU Vcore 2.2V = CPU Vcore + GPU Vcore? Because I'm using G620 GPU and not using extra VGA card.
But, If CPU Vcore 2.2V = CPU Vcore + GPU Vcore, the voltage is fix at 2.232V and never change even I test playing movie or test using Prime95. The only keep changing is VIN4 and the differences with VID is about 0.1V-0.2V.
From this, can I say that VIN4 is CPU Vcore(Based on HWMonitor)?
I want to undervolt G620, so I need to make sure everything first. Thanks.
*edit
I don't know which BIOS I'm using. From ECS website, the latest BIOS is updated on 2013 but I'm using 2014 BIOS(Based CPUZ). No BIOS version on ECS web. All based on date. I'll ask ECS about this. Thanks.
