Someone desoldered all 4C10N mosfets and CHL 8510 drivers and also changed the resistors. . What should be the value of the resistor in the picture? I don't have 4C10N, can I use the 4C09N ??

I soldered 5 phases and started the card. Something is wrong VRM Efficiency 100% .

VRM Efficiency looks fine. It is efficiecncy of DC-DC converter, not "the percent of max tdp", that is shown for nvidia. However >100W power draw for idle card seems really incorrect. 100W without spinning fans would quickly put the gpu much hoter than 50°... It looks either like incorrect measurement, or like some ICs of of DC-DC converter are eating 100W and are extermely hot for idle mode. |

I found two damaged resistors, probably measuring ones. I could not read their values. I soldered with a value of 000 like the others next to it. Unfortunately, it did not help the card still in idle have 100W.Any ideas what to do next ??

I don't think that these are measuring. They may be related to some power phase, and zero resistors often are not damaged by themselves, but a burned due too high current. So, I suggest re-checking that all about phases related to those zero resitors are fine |

I replaced the Ir 3567B but it is still the same, the power supply system is slightly warm. There are strange jumps in the current consumption in the 100W-150W gpuz. The card can hang during these jumps. Once I saw even 1.5V on the gpu. I have no idea what lying to the measurements ?? |

It turned out that the card was mechanically damaged. A broken pad under one of the coils, someone tried to stick it. After removing the coil, the card has normal consumption. Thanks for your help. |
