Unfortunately, some optane-compatible platforms will be updated to the later on firmware if your boards' production/shipping date is late, which might removed some features.

Hi guys,
After a thorough inspection,
I've come to the conclusion that this motherboard is right for me:
MS03-6L0+ES QYFS/R
Buying a dual-socket one doesn't make sense.
Two CPUs will use at least 500W, which is a lot.
And DDR5 memory is currently very, very expensive.
The only other option is to buy Intel Optane PMem 300 Series.
If anyone has any additions.
Any information is welcome.

Could you please refers where is the source of the info "MS03-6L0 support PMems"? Theoretically it does, however without advanced BIOS modifications, MS03-6L0 will not be able to boot with it. If you are insist with GBT products, MS03-CE0 is an available SKU with PMem compatible feature. This is caused by, the MS03-6L0 does not belongs into the certain Intel's project, and is a later SKU compare to MS03-CE0.

What if use an earlier BIOS version MS03-CE0?
For MS03-6L0
Where is there support for PMem
almost certain it will work.
Correct me if I'm wrong.
MS03-CE0 would work as long as the PMem 300 module you have are functioning and been inserted with the correct population.
MS03-6L0 just like what I posted, the hardware features and electrical features of it definitely support the PMem modules, just about the firmware issue. For now the feasibility verifications of this action is still in process, therefore I cannot give you a 100% sure for that.
For the sake of the stability and capabilities, MS03-CE0 would be the better choice. (also if there is no changes to the GBT global pricing, MS03-CE0 is cheaper than MS03-6L0. Differentiation could occur for different region)

R12 ver. stuck at memory initialization B7, older BIOS like Fxx, or Dxx in this link is needed
I have tested 1 pcs NMC2XBD128G6S + 1 pcs 16G DRAM in MM mode with QYFS
PMem must be populated in the same memory controller like {A,B} {C,D} {E,F} {G,H}.
Here are the results under linux, tested and concluded by agent
Speeds, AppDirect mode (module alone, non-interleaved, namespace0.0 fsdax, ext4 with dax=always, fio 3.33, each job given its own region):
seq read bs=1M, 8 jobs: 10.6 GiB/s (11.4 GB/s)
seq read bs=1M, 1 job: 3.5 GiB/s — CPU-bound, sys 99%, 4+ threads needed for peak
seq write bs=1M: 2.5-2.6 GiB/s (2.7-2.9 GB/s), saturates with a single thread, adds nothing past nj1
4k rand read qd1 (libpmem, mmap direct): 668k IOPS, avg clat 729 ns
4k rand write qd1 (libpmem): 408k IOPS, avg clat 1.32 us
4k rand read/write via block device O_DIRECT qd16: 429k / 451k IOPS
Speeds, Memory Mode (16 GB DDR5-4800 as the volatile cache for 127 GiB, single job, bs=1M):
8 GiB working set, fits in the DRAM cache: write 1603 MiB/s, read 2584 MiB/s
90 GiB working set, far exceeds the cache: write 1068 MiB/s (1.12 GB/s), CRC32C verify read-back 1749 MiB/s (1.83 GB/s)
average clat for 1M IOs: 574 us write, 461 us read
Now using PMEM100 in my X11-418G supermicro rig,
- Current Latest Bundle: X11DPG-OT-CPU_4.7_AS1.74.19_SUM2.14.0.zip
- BIOS Revision: 4.7

I've tried every possible option, but for some reason, no launch.
It displays the message shown in the screenshot.

Thanks a lot.
I'll give it a try now.
I have 32GB modules Samsung.
Note:
If I understood correctly, I need to add a kit to the RAM modules I already have
Supported configurations are described here, page 7:
X12 is less flexible than X11. You have to do 6+1, leaving one channel unpopulated, or get two more for 4+4. And, for whatever reason, you can't use 1Rx8 RDIMM alongside Optane DCPMM.

What should I do if I only have two sticks of PMEM?
How do I install them?
The remaining modules are 64 GB each.
6+1 only AD mode.
you need two more for 4+4 to support memory mode.
