I use dunkin donuts 4 cup holders, inexpensive. I like to keep the rigs exposed to get max cooling and or heat dissipation during summer/winter. But i am starting to put things into cases to cut down on my dusting and consolidate...

I managed to source two Xeon Platinum 8272CL for 800$ per CPU and wondering if they will work with Supermicro X11DPI-NT motherboard.
Plat 8272CL - 26 cores 2,6Ghz, 3,7 Ghz turbo. TDP=195W
from the TDP (195W) they should work, if they have higher thermal design current(TDC) you can request a VRM upgrade from supermicro(if your board is not under warranty you can do the VRM modd yourself)

Unfortunatelly mobo isnt under warranty ;-(

I'm thinking to source DELL 7920 barebone but not sure about the compatibility due to CL version of the CPU. Whats the chance it will/wont work ?


Thanks for help.

Hello,

just to be sure, the tutorial from RolloZ170 to patch the VRM on SuperMicro boards will not work on the X11SPA-T, X11SPA-TF, because these boards does not have the old needed BIOS2.x? I would like to run a 8273CL...

Thanks in advance!

the BIOS can reject the TDP in some board with up to 165Watts support, boards with 205W support normaly have NOT a TDP limit block in BIOS.

i.e: if you modd a X11SPL for 8273CL the CPU will start POST after the VRM modd but the BIOS will report a "over specs CPU" and reboots after some seconds. to overcome this you have to use BIOS 3.1 or older or remove the TDP limit of the BIOS. i have BIOS with 255W limit for X11SPL/X11SPM.

X11SPA should NOT have a TDP limit because the up to 205W support, if supermicro do one in the future the BIOS must be modded or you have to use an older one without TDP block then.

Got it! Thanks for the clarification! So there is a good chance, that the steps for the X11SPM could also work on the X11SPA-T too? Then I would buy ElmorLabs device and would give it a try!

Hi guys,
I'm having problems getting the QDCS (CPUID = 0306F0h) to boot in my motherboard Jingsha X99-8D3.
I've tried various BIOSes with 306F0 microcode included by default and the board gives FF post code, however if I use BIOSes with 306F0 microcode removed then the CPU is able to get past FF, yet it's stuck at code 79.
Has anyone an idea of what is going on here?

Hi experts,
I have a couple of x11dpu g6 ni22 boards which is effectively an X11dpu that shipped as a Nutanix system. I have no idea what the difference is aside from maybe the firmware as physically they look identical. Anyway, I am hoping to chuck in some ES CPUs, now I can see the X11DPU supports quite a range without a mod, so my questions are:

Would I be able to chuck standard X11 firmware on the board and therefore any modded firmware, or am I stuck with the Nutanix specific firmware, in which case does anyone know which firmware would support the ES CPUs? They use a different naming conjecture.

for the skylake ES stepping B0 i.e. you need a older BIOS (without 2nd gen support)
if you have a file we can take a look in the BIOS.

I'll have a dig around and see if I can find an archive of the older BIOS's, the oldest that is easily accessible is https://download.nutanix.com/kbattachments/7812/NX11DPU1.B30.PU50.002.Signed.bin which would only be 12 months old

Edit: Managed to find an older BIOS: https://s3.amazonaws.com/ntnx-sre/G6-BIOS/PU21.000/NX11DPU8.808

looks not special, but has different BIOS ID which prevents update to regular X11DPU BIOS with standard methods. but with programmer should work. this BIOS includes two microcodes
50652 SKL B0 PRE
50654 SKL H0 PRD

Thanks for taking a look - would that mean with that firmware I should be able to chuck in a processor such as QL29 without modifying the BIOS, or would I still need to make some changes?

I've also got a couple of QJW5 units here which I will try at some point too.

QL29 should work yes.
Note: the IPMI GUI maybe does block the downgrade

50651 SKL A2
no way, they are known to work only in HPE with oldest BIOS.

Hi @RolloZ170, as you know I purchased the Intel Xeon Gold 5218 ES version qq8m
for one of my 2 - X11DPL-I's (140TDP)

For the second board I was looking at the Intel
Xeon Gold 6148F QS QN3G 20C 2.4GHz 3.1/3.7GHz 27.5MB 150W


I see this is a 150w TDP will my board run it? Plus your opinion on the
Gold 6148F QS QN3G 20C vs the Gold 5218 ES version qq8m

thanks in advance
