For Intel® Optane™ persistent memory (Intel® Optane™ PMem) see troubleshooting steps taken according to symptoms.

Fail to Boot or Blue Screen troubleshooting

  • Verify according to supported operating system (OS) list, Operating System OS for Intel® Optane™ Persistent Memory.
  • Verify proper BIOS and PMem firmware installation. Contact Intel Support if necessary:
    • PMem firmware (FW) is released with Platform BKC. The download site requires a non-disclosure agreement (NDA).
    • If you need to contact support, visit Contact Support and under Memory and Storage, click Intel Optane Persistent Memory.

The total physical memory is incorrect according to the system

There are several reasons for incorrect total physical memory capacity:

  • Some overload loss (around 2%-3%) is to be expected.
  • In Memory Mode, DRAM memory is used as cache. Therefore, DRAM memory is not counted toward total memory.
  • Violation of population rules for Intel® Optane™ PMem and DRAM will likely provide unexpected capacity. See Module DIMM Population for Intel® Optane™ Persistent Memory.
  • A processor's SKU suffix determines total memory capacity.
    • No Suffix - 1 TB per socket
    • M - 2 TB per socket
    • L - 4.5 TB per socket
    • For additional information about memory capacity suffixes, see About Intel® Processors.
