i do not do anything about TDP. i change ICC_MAX of VRM controller to match thermal design current(TDC) of the processor.
this does not apply to the LGA4677 platform.
VRM modify ICC_MAX to run high TDC OEM cpu

some day. all seller of ES want that info, and after they got the info they can rise prices.
Sorry，That my fault，I mean change ICC_MAX of VRM controller to match thermal design current(TDC) of the processor for LGA4677 platform
Could you write a program for 4677 platform to change TDC when you free?
there is no need for this. why do you want that ?
i checked already if one processor don't work because of TDC on a gigabyte motherboard with MPS MP2973 controller,
MCP2221a don't support this for some reason. but the MPS dongle EVKT-USBI2C-02 with MPS Demo app can access.
result was ICC_MAX is high enough. e.g. OEMs with TDP 385W do not have higher TDC.
with a processor TDC=550A and ICC_MAX set to 500A the board still worked.
Gigabyte and Supermicro use MP2973 (MPS, preprogrammed 2971)
ASRrock Rack use RAA229126 (renesas)

I've got a pair of 8272CL / SRF89, but they do not work in X11DAi-N (tried CPU1 only, with either of the two). Same result - board powers on the PSU, but the power draw is ~25W and it does never jump to 50W+ as with a other working CPU (4208) on the same board.
Do I still need to reprogram the VRM for these "odd" CPUs? Or the issue is in the microcode?
A normal/public/legit CPU which fits the TDP would work out of the box I assume?
Also the same question for X11DPG-QT (but that one does not run yet.. BMC is "dead" - does not even make access to its QSPI, and then I noticed some damaged parts under the PCH, so likely some power sequencing or reset issue on this poor board).

8272CL = OEM
TDC = 255A
X11DAi-N supports out of the box max. 228A
you need VRM mod/program.
as descibed above, not a TDP issue.
X11DAi-N BIOS has no TDP block.
same with X11DPG-QT.
edit: the only SM boards with TDP block are X11SPL and X11SPM, with a TDP=205W CPU you will see:
the installed processor is over spec, the system will reboot in xx seconds....

Hi Rollo,
Great Post, I think your solution is exactly what I need for my Dual CPU Dell T7820 workstations that I received in a part exchange deal, I ordered the CPUs (from ebay-china) which were the Intel Xeon Platinum 8175M CPUs thinking they were an absolute bargain (not knowing about TDC/TDP limits in my machines). I saw them online and recommended them to one of my customers who ordered a Riser Kit from me, The CPUs he ordered (8175m) on my recommendation arrived to him a few days ago and it did not work in his machine, he came back to me asked me if I could help. In my head I assumed its LGA3647 Gen 1 CPU, then this boards supports Platinum Gen 2, so it should be fine. After some digging I arrived at your post realising that the TDC on these CPUs is higher than my system can produce. I've been trying my best to digest as much info as I can, but its all a bit overwhelming for me.
Can you point me the right direction, I would really like to learn how to it and I realise that I would need to purchase some equipment (happy to do that)
I would really appreciate some help and guidance from yourself or others. I get very overwhelmed with stuff like this, I can update a Bios from Windows and Install Windows 11, this stuff is above my current pay grade.
I have 10 of these machines and 20 CPUs making their way to me from China.
Kind Regards, Abdul

you need MCP2221a (adafruit or similar) and my c# app (link at 1st page)
no, we are all here not pretty enough for this. and our girlfriends have all two left hands, sorry.
and so far it works fine without.

Hi Rollo, do you think this mod would work or be suitable for this motherboard, specs say is Max 205W support.

MD71-HB0 usualy runs dual Platinum 8175M (TDC=255A,TDP=240W)
i am sure this is also valid for MD71-HB1 because microcodes SKL B1 are included in the BIOS,
If not, you can do the mod of course. there is no additional TDP block in the BIOS.
Just a follow up, me and mate did our first one today, however we managed to brick one system which I will come back to later, the second system was a success after some faffing.
We directly soldered our wires to the PJPPT, saved the hassle of removing the entire board from the case, also realised you can only code for the second CPU if second CPU is present (else coding wont work), also for some strange reason the system required 2 sticks of ram to get going, it simply refused with one stick (stuck in some loop), hopefully this helps someone out
Back to the board getting bricked, it is now in Bios Recovery Mode (according to the manual - 3 White and 3 Orange flashes), I think when we booted it up for some reason or other I think it went into Bios update mode, at that point my friend who had the HDMI output cable running via some sort switch which lost signal, after a while of it being on white light and no screen we switched the machine off. (in hindsight I think the system was flashing at that point). This brings me to recovery, what is the best way of re-coding the Bios, can easily get the existing chip(s) and removed them if needed, are the Bios's serial specific (locked to one machine) and that data needs to be transferred to a replacement or can I just copy data from known good bios and transplant it over?
While we are at for good measure can we whack in re-sizeable bar, the system is capable, to my knowledge its been done on 7910, the manual states it can run an RTX 3080 with re-sizable bar enabled.

once run Intel ME/SPS is bond to PCH(chipset) serial for TPM/security functions. dump from other machine will not work(or just for some time)
you need to clean un-initialize(back to only configured) the ME/SPS first(don't know if possible)
if you talk about BIOS modify i am not sure if this is possible. i tried with a prec. 5860 BIOS(LGA4677) with no luck,
Intel BIOS guard is enabled, changes will be redone or BIOS do not work.

Sorry, I couldn't find the location to connect the MCP. It seems to be different from the DL360 Gen10. I’ve taken photos of all the available connectors on the motherboard. Could you please help me identify the correct one? Thank you very much!
