HMA82GR7DJR8N

The HMA82GR7DJR8N is a DDR4 SDRAM RDIMM — a 16GB memory module carrying SK hynix’s own DRAM components, not a discrete chip. Every figure below comes from one row of the ordering-information table in SK hynix DDR4 SDRAM RDIMM module data sheet, based on 8Gb D-die, Rev. 1.2 / Jul.2019 (manufacturer-restricted document).

Key figures

• Module capacity as printed: 16GB.
• Module organisation as printed: 2Gx72 (this is the lane width of the module).
• Component composition as printed: 1Gx8(H5AN8G8NDJR)*18.
• Ranks as printed by the table for this row: 2.
• Supply as printed in the feature list: VDD=1.2V (1.14V to 1.26V).
• Data-rate marking: the document lists speeds up to PC4-3200 for this module family; the per-module speed sits in the order-code suffix, which this document does not decode.

Complete order code — what this document leaves open

The part number on this page is the module base code. The ordering table prints the suffix field for this row as a set of alternatives rather than one value, and the document carries no decoding table for those letters. We therefore publish the base code and do not invent a specific speed-and-suffix combination — that would create an orderable number the manufacturer has not published here.

Operating temperature and lifecycle — deliberately not claimed

This document prints no operating-temperature range and no product-status statement for these modules, so both fields are left empty here rather than borrowed from the underlying component datasheet or from any third-party listing. Distributor and aggregator pages are not an acceptable on-page source on this site.
