MemTest86 Version 11.7 Introduces Preliminary Support for LPCAMM2 Memory

PassMark’s MemTest86, a widely trusted memory diagnostic tool, has released version 11.7 (Build 1000) with significant updates, most notably the introduction of preliminary testing support for the LPCAMM2 memory type. This enhancement is particularly relevant for users of Intel’s latest “Meteor Lake” and “Arrow Lake” processors, which are among the first platforms to adopt this new memory form factor.

LPCAMM2: The Next-Generation Memory Form Factor

LPCAMM2 is rapidly gaining traction as a modern memory solution, with early implementations appearing in devices such as the Lenovo ThinkBook 14+ and 16+, as well as the Framework Laptop 13 Pro. Major DRAM manufacturers, including CXMT and Samsung, are leading the way with LPCAMM2 modules. CXMT’s offerings utilize LPDDR5X-8533 modules, while Samsung’s modules feature LPDDR5X-9600 memory stacks. With additional support from SK hynix, Micron, and CXMT, LPCAMM2 is positioned to become a universal standard for laptop and compact device memory.

The upcoming DDR6 memory standard is expected to further drive the adoption of (LP)CAMM2 modules, making robust memory testing tools like MemTest86 essential for ensuring reliability and performance.

Key Fixes and Enhancements in MemTest86 11.7

  • Preliminary support for LPCAMM2 faulty die decoding on Intel Meteor Lake and Arrow Lake chipsets.
  • Integration of LPCAMM2 support in the module graphical report.
  • Inclusion of unknown slot error counts in module graphical reports saved as bitmap images.
  • Display of module form factor information (e.g., LPCAMM2) for detected SPD modules in reports.
  • Added CPU, ECC, timings, and decoding support for Intel Bartlett Lake chipsets.
  • Expanded ECC, timings, and decoding support for Intel Raptor Lake and Arrow Lake chipset variants.
  • Support for measuring TSC frequency using the ACPI PM timer when HPET or PIT is unavailable.
  • Resolved issues with enumeration of physical memory slots when SMBIOS contains an entry per DRAM chip or die, particularly on boards with DDR5 modules.
  • Corrected physical slot layout for Intel Arrow Lake 2-slot boards with swapped memory controller ordering.
  • Fixed faulty chip decoding for 1R SODIMM modules on Intel Meteor Lake and Arrow Lake chipsets.
  • Improved memory speed reporting accuracy on Intel Meteor Lake chipsets.
  • Fixed reading of DDR5 temperatures when volatile register MR11 is not set to zero.
  • Resolved a bug related to disabling hyperthreads in the Free version of MemTest86.

With these updates, MemTest86 continues to provide comprehensive and reliable memory testing for the latest hardware platforms, ensuring users can validate the stability and performance of cutting-edge memory technologies like LPCAMM2.
