Frequently Asked Questions

What does Low Profile mean for server memory?

Low Profile (LP) DIMMs have a reduced height compared to standard DIMMs, making them suitable for space-constrained server chassis where standard-height DIMMs may not fit due to airflow or component clearance restrictions.

Is the HMCG94CHBRA compatible with Intel Xeon Sapphire Rapids?

Yes, it is compatible with Intel Xeon Scalable Sapphire Rapids server platforms supporting DDR5-6400 ECC RDIMM. Verify your specific server's QVL before ordering.

What is the difference between HMCG94CHBRA and HMCG94CHBRA280N?

The HMCG94CHBRA is the base part number while HMCG94CHBRA280N includes an additional suffix indicating a specific production revision. They are functionally equivalent — verify with your server's QVL for specific revision requirements.
