What are the supported DDR4 UDIMM module configurations that enable an Intel® Xeon® E-2126G Processor to support 128GB of total ECC RAM?
The Intel® Xeon® processor E-2100 product family originally supported a maximum of 64GB of RAM. Later, support for 128GB of maximum RAM was added.
Per the Intel® Xeon® E-2126G Processor "supplemental information" sub section of the Intel® Xeon® E-2126G Processor product specification page:
"Support for up to 128GB system memory capacity will be available in 2019 and requires both a BIOS update and hardware platform support. Please contact your hardware provider regarding availability for your system."
Page 18 of the processor family datasheet vol 1: "The system memory interface supports two channels of DDR4 memory with a maximum of 2 DIMMs per channel."
Meaning, this CPU family can take 4 sticks of RAM.
Page 19 of the processor family datasheet vol 1 lists numerous supported ECC and non-ECC UDIMM configurations. None of the supported configurations contain a DIMM capacity above 16GB.
The only supported DDR4 UDIMM module configurations total 64GB because there is no DIMM capacity listed greater than 16gb.
What kind of ECC RAM do I need to buy to get 128GB of RAM working with this CPU?
Following the update, do I need to use registered ECC or do I need to use unregistered ECC to get to 128GB?
I tried to open a support ticket with Intel but there is no option to select the "Intel® Xeon® E-2126G Processor" when choosing the product a customer needs support for.
Thanks for your help.
