turn of translator...
other chip is 62, same I2C bus. try to modd again, sometime the connection is interupted by BMC/iDrag
VRM modify ICC_MAX to run high TDC OEM cpu

Great! So helpful! It's working well! Struggling with the DELL BMC(BTW, I really hope the program could run directly on my MBP...

nice try ,im not think to mod the thermcooler like this, the 3647sok cooller so expsive rightnow
do yourself: locate the VRM controller, trace SDA/SCL to a header (or solder to series resistors)
Some New H3C motherboards do not have VRM debugging for export. For New H3C servers on the C35 platform, I suggest you use probes to modify them.
For New H3C, it is quite difficult to modify. You can refer to the data manual of TPS53679, then use the GND pin of MCP2221A to the grounding position of the fan interface, and finally debug the output according to the PMBUS of the pin. Use a probe to hold down and make modifications. It requires the installation of two CPUs for modification in a shutdown state, which is to connect the power supply, but do not turn on the machine, and then use tools for modification.
Did you see near your fan interface? If I remember correctly, there is a three pin PMBUS debugging lead out.
And The HR650X
VRM位置一般位于CPU插槽附近，对于HR650X的PEX1610C而言，其VRM引出的I2C接口仅有一个，刷写单个即可实现大功率支持。位于CPU1的插槽左下方位置。对应针脚从上往下分别为 SCL SDA GND。
The VRM is usually located near the CPU slot. For the HR650X PEX1610C, there is only one I2C interface led out by the VRM, and flashing a single interface can achieve high-power support. Located in the lower left position of the CPU1 slot. The corresponding pins are SCL SDA GND from top to bottom.
here it is:https://ww1.microchip.com/downloads...oftwareLibraries/Firmware/MCP2221Terminal.zipCan you send me the download link for MCP2221 Terminal
I've been searching for a long time and can't find MCP2221 Terminal.
我找到了这个接口，正在等待工具到
I found this interface and waiting for tools
I find two interface near VRM and they look same, how i should confirm witch is SDA or SDL?
Attachments
use multimeter(beeeeep)
there can be a 30ohm resistor in series to the VRM controller pins.
TPS53579
SDA(26)
SCL(24)
Has anyone done this to perform a code audit?
Thank you for your years of work here Rollo.
Hey for devices I need to do this with it's doable with these 2 correct? Just want to make sure before I order have a DL360 G10 and want to run 8171Ms or 8124Ms on them.

yes correct. the I2C header may not populated, you have to solder or some helping hands.
Yea I can do that i have some stuff from my ardunios and rpis I can use for that. Just wanting to make sure I am buying the right things.
Sorry if youve already mentioned this before but I have the following with the adafruit and was wondering which of the 4 wires I would connect etc. This is my first time doing it so I am a very big noob here with this. Wishthere was a discord to talk about this in or have someone walk through for the first time lol.
How long does it take to program once the script is started cause could I get away with just taping the connectors down good or holding them down really good? I have to do this like 50 times.
