Sorry, I have sold all these boxestwo possible issues between powergems.
Pinout of the cable / connectors.
And the Controller used in the Powergem.
I suspect that they have i2c wired up so that the NVDIMM can get telemetry from the Gem.
Through that, it could check for a specific controller used.
Datasheets for a a LTC3350:
Technically its the wrong manufacturer since the logo on the chip shown in the pictures refers to Linear Technology (LT) and not Analog DevicesLTC3350 Datasheet and Product Info | Analog Devices
The LTC3350 is a backup power controller that can charge and monitor a series stack of one to four supercapacitors. The LTC3350’s synchronous step-down controller drives N‑channel MOSFETs for constant current/constant voltage charging with programmable input current limit. In addition, the...www.analog.com
@nasbdh9 you could do as a favor in grabbing a multimeter and measuring the pinout of the powergem connector going to the NVDIMM.
Analog Devices bought Linear Technology a few years ago.two possible issues between powergems.

No signs for nvdimmm support in current bios (v2.4) for h12ssland a sm h12.
most likelyDo I need to install an NVDIMM to get options in BIOS to show?
yes, but the settings for Optane and NVDIMM are different.Are the options hidden if you don't have any Optane memory?
Other types of NVDIMM or types?
don't expect these 4 extra slots to be for NVDIMM. this is mostly only A2 / D2.Unknown (Wynnsynn?) Dual LGA3647 Skylake-SP with 4x NVDIMM slots flanking both CPU. It's the 1U Hyve 8x LFF chassis in the Deals section (or check my posts).
What gives me a little hope is that the BIOS had NVDIMM options. At least, from what someone else posted. I'll find out today.don't expect these 4 extra slots to be for NVDIMM. this is mostly only A2 / D2.
memory population guide(manual): populate A2 / D2 only if you don't have enough memory.
Note 2ng gen scalable(non 'M' non 'L') support 1TB of memory, 8 x 128GB does the job with all 6 channels populated.
4x 256GB will also be 1TB but only quad.channel operation.
you can put NVDIMM-N with backup batterie and or flash storage in every memory slot. this memory should not be erased on POST memtest, any idea why?What gives me a little hope is that the BIOS had NVDIMM options. At least, from what someone else posted. I'll find out today.
