GPU available power limitation below than 400W

HW: Apollo 6500 Gen10 plus (XL675d Gen10 plus or XL645d Gen10 plus)

 

Symptom: 일부 Apollo 6500 Gen10 plus System에 장착된 Modular GPU의 가용 전력 제한에 따른 성능 저하가 발생

 

nvidia-smi툴로 정보 열람 시, 전원 가용 한계치가 최대치(400W)가 아닌 정보로 설정됨

 

정상/기대 전력:

Power Readings

        Power Management                  : Supported

        Power Draw                        : 66.18 W

        Power Limit                       : 400.00 W

        Default Power Limit               : 400.00 W

        Enforced Power Limit              : 400.00 W

        Min Power Limit                   : 100.00 W

        Max Power Limit                   : 400.00 W

 

이상 전력:

Power Readings

        Power Management                  : Supported

        Power Draw                        : 81.09 W

        Power Limit                       : 400.00 W

        Default Power Limit               : 400.00 W

        Enforced Power Limit              : 350.00 W

        Min Power Limit                   : 100.00 W

        Max Power Limit                   : 400.00 W

 

Recommended Action: Advisory 내용을 바탕으로, Power Updater를 이용하여, 전력 제한 이슈 해소
