M425R3GA3BB0

The M425R3GA3BB0 is a Samsung DDR5 Small Outline DIMM (SO-DIMM) memory module – a complete plug-in memory stick, not a discrete DRAM component. In this datasheet’s ordering table it is the 24GB capacity member of a three-module family built from Samsung’s own 24 Gb DDR5 B-die. The document is a Preliminary specification, so its values may change.

Key figures

• Module capacity: the ordering table prints 24GB for this part number.
• Interface width: the module is x64 (64-bit DDR5, non-ECC SO-DIMM).
• Component composition: the ordering table prints 3Gx8 using K4RHE086VB (8-wide) Samsung DDR5 component dies.
• Ranks: this is the single-rank (1 rank) member; module height 30MM.
• Supply: the datasheet prints “VDD = VDDQ = 1.1V” and “VPP = 1.8V” for the on-module SDRAM.

Complete order code – what the datasheet leaves open

This part number is a module base code. The datasheet’s ordering table prints it with a single speed suffix – CWM, which the table’s note defines as “5600Mbps 46-45-45”, and states the module is “Backward compatible to lower frequency” (its speed-bin table lists DDR5-4400 / 4800 / 5200 / 5600). Unlike a later revision, this Preliminary table enumerates no further trailing fields, so this page presents the module at its base code and does not invent additional suffix combinations the manufacturer has not published here. Resolving the exact orderable codes is tracked as N270.

Operating temperature – deliberately not claimed

This datasheet prints no Recommended Operating Temperature grade for the module; its only thermal figure is a refresh-interval statement covering case temperatures up to 95°C, which is not an operating-grade claim. So this page publishes no temperature grade or range claim; the temperature field is left blank. Tracked as N270.

Lifecycle status

The Lifecycle field is left blank: the datasheet is marked Preliminary (Rev. 0.5) and prints no product status. We have not verified a reachable per-code Samsung module product page, and third-party retail or distributor listings are not an acceptable on-page source under this site’s rules. This page makes no Active or End-of-Life claim; the gap is tracked as N270.

Provenance

Every figure above is taken from Samsung DDR5 Small Outline DIMM (SO-DIMM) module datasheet **Rev. 0.5, Jun. 2023 (Preliminary)** (81 pages · md5 34a4aa413ea450017f8c68b25ed57b0c · page footer Preliminary Rev. 0.5, SAMSUNG), a channel-local copy of the manufacturer’s own module datasheet. Its PDF /Info carries no aggregator watermark and it prints SAMSUNG footers with a part-number-level revision history, but it is a Preliminary, CONFIDENTIAL-marked document with no byte-identical public copy verified, so the manufacturer datasheet button is left unpopulated and we do not host the file.

Who makes it

M425R3GA3BB0 is a DDR5 SO-DIMM memory module of Samsung Electronics Co., Ltd. – Samsung’s own module built from Samsung DDR5 component dies (the ordering table names the K4RHE086VB die it carries). The “M425R…” code prefix resembles a Micron-style number, but the document is Samsung’s: the page footers print SAMSUNG, the revision history and component composition reference Samsung’s K4RHE-series dies, and the copyright is Samsung Electronics Co., Ltd.
