VRM modify ICC_MAX to run high TDC OEM cpu

[jhgjhgj]

try all until you found two, you just get "not found" if there is no 1610c on that address.
after that report the HP model and addresses, thanks.

HPE DL380 G10 modify successfully with 62 64 address.
I will try with Fujitsu RX2530 at next week.

ok, i bought a DL380 motherboard to investigate this

HPE DL380/DL360 Gen10
PXE1610C addresses 62, 64
VRM connector: J226 see picture for pinout)

connect MCP2221a (prepair programming with other PC)
i made a c# console app for automatic programming ( MCP2221a_iccmax_FF(10052024).7z ) vrm PXE1610C
install CPU1+2, some memory and power up the board, enter BIOS.
1st socket "MCP2221a_iccmax_FF -PXE1610C 62"
2nd socket "MCP2221a_iccmax_FF -PXE1610C 64"
or
1st & 2nd socket "MCP2221a_iccmax_FF -PXE1610C 62 64"

J226

plat 8222CL is TDC=255A too

Yes please let us know how did you connect to physically which location on the board?

added HPE DL380/DL360 Gen10

 

[RolloZ170]

my latest c# app ( MCP2221a_iccmax_FF(10052024).7z ) , supports now a bus scan function.
"MCP2221a_iccmax_FF -scan start end"

Any idea about Asus Z11PA-D8? Support page says "1st and 2nd Gen Xeon® Scalable Processor Family (165W)"

CPU support list includes Platinum 82xx up to 165W

sorry too weak.

One more, what about Gigabyte MD61-SC2 ? It's discontinued, but the QVL list shows support for several 205W 82xx CPU's, like 8268, 8270 etc..

Also i assume that mezzanine slot is pretty useless in a standard E-ATX capable tower case? Thx.

most likely, but not confirmed.
the release note of older BIOS that states support of P-8124(B1, TDC=255A) and P-8136(B1, std.TDC)
but the microcode B1(50653) for both is there.

Guide in the Guide:
modify X11SPL-F & X11SPM-(T)(P)F BIOS 3.9 to support 255Watts
download the BIOS 3.9 from supermicro.
download HxD or use your favorite Hex Editor and open the BIOS file.

( A5 hex = 165 dec. / FF hex = 255 dec. )

X11SPL BIOS 3.9
( this is only correction of ProjectPeiDriver.ffs checksum )
search for "26 22 9C 73 64 32 54 44 99 1C 8D C4 4A 73 D6 AF 62 6C"
replace with "26 22 9C 73 64 32 54 44 99 1C 8D C4 4A 73 D6 AF 62 B8"

X11SPM BIOS 3.9
( this is only correction of ProjectPeiDriver.ffs checksum )
search for "26 22 9C 73 64 32 54 44 99 1C 8D C4 4A 73 D6 AF 62 4A"
replace with "26 22 9C 73 64 32 54 44 99 1C 8D C4 4A 73 D6 AF 62 96"

X11SPL / X11SPM BIOS 3.9
search for "6C 68 A5 00 00 00 68"
replace with "6C 68 FF 00 00 00 68"

X11SPL / X11SPM BIOS 3.9
search for "FB B9 A5 00 00 00 5E"
replace with "FB B9 FF 00 00 00 5E"

save as "BIOS_X11SPL-096E_20230315_3.9_255W.bin" respective
save as "BIOS_X11SPM-095D_20230315_3.9_255W.bin" (just for example)
its works now, here is a proof

Anyone have that 3.9 bios laying around? Wondering if X11SPM-TF would be able to work with 8259CL with this mod and bios?

yes.

 

[Jon]

yes.

Thanks for the quick replay will push the moded bios per your instructions and see were I end up. For now with bios 2.1 that I was using for my ES chip the new 8259CL is not posting and in the IPMI I only see FF on the post

sure, needs at least BIOS 3.0 to support 2nd Gens.
8259CL without the VRM mod the board just turns on, no x86 code is executed.

now updated the GUIDE for BIOS 4.0

Thanks that was quick. Will try this out soon. But at the moment bios updates seem to not work on my board. I run the Bios update via the IPMI or SUM and seem to stay stuck to 2.1 bios after power cyle? So could have a bad board or a other issue to figure out first?

 

[Jon]

For now I can confirm that my 8259CL (shows up as 8255C in CPUz but a 8259CL in cinebench and taskmanager ) seems to work in my Asrack EPC621D8A with bios P2.10 that had a 8124M in it. So back to trying that Supermicro X11SPM -TF bios to update and old the update

 

[Stephan]

Caveat on BIOS 4.0: Contains fix for Intel "Downfall" and that can be a performance killer. Here is one lawsuit: https://regmedia.co.uk/2023/11/09/pacer_intel_downfall_lawsuit.pdf I don't know how many there are.

 

[Jon]

Seem I am in a similar state as the link bellow. I think I upgraded the firmware and bios via IPMI with the Systhem powered on? So ran into that ME error and reading the thread maide me realise the systhem was probably on.

https://forums.servethehome.com/ind...recovery-mode-when-updating-bios.14380/page-3

Still have access to IPMI but cant seem to power it off via the IPMI need to hold the power button. The bios was set to auto power on on return of power and forgot about that after swapping the chip.

So back at it trying to get a moded 4.0 to post as to see it correctly in the IPMI after.
