MS-16L13 Posted November 16, 2022 Share Posted November 16, 2022 A brief analysis of the power supply of the CLEVO 30 series MXM graphics card. A total of 11 phases of power supply, 7 phases to the core, 2 phases to the memory, 2 phases of auxiliary power. After multiple data checks Mos tube parameters stable 50a maximum 60a, inductor isat 70a irms 45a. This time the question arises, the discerning eye can see at a glance that the parameters of this inductor has a big problem. This package of inductors can have such high parameters, in fact, there is really no, and the false label is very serious. The real isat may only be about 30a, and the inductance drops very quickly, and the datasheet does not match. 1 Link to comment Share on other sites More sharing options...
MS-16L13 Posted November 16, 2022 Share Posted November 16, 2022 Original inductor test 1khz frequency 19a when the temperature drift began to appear What concept isat and irms all false mark more than 30%. After replacing the new inductor without heat dissipation 1khz test 30a temperature 76 degrees inductance value no change, datasheet isat standard 37a 20% inductance value decay fully met the standard. Heat gun heating inductor over a hundred degrees 1khz test 25a still no significant change. 1 Link to comment Share on other sites More sharing options...

What values did you choose for the shunt resistors and did you update the phase count resistor network? Since I've updated my cooling I only get to about 57C at 1900Mhz core clocks during cyberpunk so I'd be interested in re-enforcing the VRM and changing the power limits. 1 Sager NP9877 Hybrid Watercooled setup, D5 pump with dual 140MM fans integrated into custom stand.

Looks like 10-15% over my simple shunt mod. I'd guess from my 1900-2000 to 2150mhz type clocks. 2 Sager NP9877 Hybrid Watercooled setup, D5 pump with dual 140MM fans integrated into custom stand.
