    Question What does the EUP Audio Jumper (EUP_AUDIO) do on my G31M-GS R2.0 motherboard?

    Hi, I have just acquired a ASRock G31M-GS R2.0 motherboard.

    The manual mentions two jumpers on the mobo, "EUP_AUDIO" and "EUP_LAN" (Manual URL: ASRock > G31M-GS R2.0)

    It states that these jumpers are set by default to "EUP Enabled" so that the motherboard uses less power in standby/off (So that that motherboard meets the Energy Using Product guideline requirements).

    It states that setting the "EUP_LAN" jumper to "EUP Disabled" will then allow me to use the Wake-On-Lan function, but would increase standby/off power usage.

    However, it does not mention anywhere what advantages I gain from switching the "EUP_AUDIO" jumper to the "EUP Disabled" setting.

    Does anybody know what I gain from switching the "EUP_AUDIO" jumper to the "EUP Disabled" setting?

    Thank you for any help,

    Sital

    Thanks for the response. I understand that by default ("EUP_AUDIO" is set to "EUP Enabled") it lowers the standby/off power consumption. But when the "EUP_AUDIO" jumper is set to "EUP Disabled", the power consumption in standby/off is increased, I was wondering what exactly is enabled that increases the power consumption?

    EUP (energy using products) appears to be a European energy conservation standard. Enabling EUP will save energy, but it might cause stability issues when it's enabled. EUP compliant hardware probably arose because of the original upcoming energy conservation standards. The easy answer to your question is that enabling EUP is done using some type of more efficient circuits when your computer is off or in standby mode. Saving one or two watts an hour doesn't seem like much, but when it's applied to millions of computers that are off or in standby mode for 10 - 20 hours per day, the kilowatt savings add up.

    I emailed ASRock and got an official answer: "Hello,With EUP enabled for audio, you might hear some “popping” sound when the system is powered on. Switching to EUP disabled might solve that. Best regards, ASRock Support"
