Hello, I am IT system administrator and i like electronics too as a hobby. I fried my homelab server Quanta S210-X12RS trying to put a gpu for AI.. and i am trying to repair it. I have some knowledge, but its limited. I am Spanish and i have 37 years old!

Thank you for this great forum!

Hello,

I have continuous BEEP from motherboard on this server after trying to use a GPU on PCIE X16. I have replaced the chipset C602 and there is no more shorts on the board. I have checked ram ddr3 voltages and are ok, but RESET PIN is low (must be high) and no voltage on any of both cpus sockets (with the cpu in the socket).

I have checked mosfets and coils and are ok, no short. I think there is no VR_ON from IC of VRM, but i dont have the datasheets nor the pinout of Infineon PX3895EDQG and PX3897EDQG. Any ideas how to check if VRM IC is getting the right signals...
