I found it.(The reason why I couldn't find it out is that there is no holes and BOX2 connector on a board.)this is from my DL360 Gen10 mobo
Thank you so much!
Hi @ RolloZ170,
Would it possible to do this mod to a Tyan Thunder HX FT77D-B7109 4U Server motherboard?
Supposedly a 205w TDP board. Asking on behalf of a customer.
Let me know
Kind Regards, Abdul

if one of the supported VRM controllers is used and you find a I2C header for programming yes.
that is not the issue. boards with support up to205W usualy do not block TDP, but TDC instead.
Experts, can you help me take a look at the Inspur 5212H5 machine? I want to confirm whether the power supply chip is where it is marked in the picture.

if this is the only PXE1610C you found the right one. some boards use PXE1610C also for RAM supply.
better zoom out the picture a but.
Thank you very much. I can't upload a large picture right now. I found this chip in the accessories of CPU0 and CPU1. CPU0 has a four-pin connector, but what is very difficult to understand is that there is no docking connector installed in the same position of CPU1.
max. 999kb (reduce quality with e.g. IrFanView) or upload somewhere (imgbb) and insert-image link.
I2C is a bus. you will see both.
do a scan, will find more than two devices thought.
There is a 3-pin interface in the lower right corner of CPU1. Can it be modified through this? If the 4-pin of CPU0 and the 3-pin of CPU1 are available, how should they be connected?
VR_PROG_CONN is enough.
most dual socket motherboards have only ONE I2C header for VR prog.
this is the pinout of PXE1610C. trace the wires to the VR_PROG_CONN with multimeter (the device with the beep)
maybe it is similar than this:
sorry.
5212 M5 is known(2x 3pin I2C), but much diff. from H5
ther may be 20...50 ohm resistors in series from PXE1610C to header. sometimes you can visibly trace.

I am about to take the endeavor of updating the HP Z8 for 8259CL CPUs. How do I even find the header location for I2C?
There doesn't necessarily have to be a header.
i would never try because they have 4+1 power stages, i can't recommend because they are too weak.
if you want to try: check what VRM controller model is used, see picture: this couled be a header, you have to measure if the controller is one of the supported.
