I have a few S2600BPB boards(Four node chassis). Can I run 2x 8273CL without the VRM Mod?
8273CL don't need ICC_MAX mod.
but they are special in some kind, maybe you have to use early 2nd gen BIOS(full size microcode)

Not even with those 20K RPM Fans in a data center environment?
there are still 3 double FAN in the blade. and beside that:
I doubt that enough +12 power can be delivered to the blade. PCB conn. and from there 2x 6 pin to the board.
some has probed 2x 8251C in a T7920 with huge problems because one CPU gets hot air from the other.
edit: only one CPU should be ok.

正确,为了完整起见:
<姓名>TPS53678 (PMBus)</姓名>
如果 EVC 发现超过 2 倍TPS53678请检查ICC_MAX以选择正确的。在 modd 之前应该是 228A 值,但高于 150A。

Hi all! Tell me, is it possible to modify the Supermicro X10DRН board for E5 2687W V4 TDP 160 Watt processors?

this VRM modd do not solve any TDP block.
i.e. a Plat.8272CL 195W does not work on most motherboards even if they support 205W TDP.
get a MCP2221a, locate JVRM1/JVRM2 and check the ICC_MAX value of the VRM controller.
if the ICC_MAX is lower than the TDC 189A of the E5 2687W V4 this VRM modd should help.
but do not change to 255A with my c# cli app, ask me for a special version ICC_MAX set to 199A.
edit:
E5-2687v4 TDP=160W TDC=189A
E5-2696v4 TDP=150W TDC=199A

Please help me take a look at the Gigabyte T181-G20, sir
Which is the power management chip
no idea. if you search for VRM controller your pictures are not helpfull.
the VRM controller is around where the coils/chokes are.
MP2956A is vrm for RAM. CPU VRM can be MP2955A or MP296x
