MTA36ASF4G72PZ-3G2

MTA36ASF4G72PZ-3G2 is a Micron 32GB DDR4 registered memory module: the datasheet cover describes it as 32GB (4 Gig x 72) and as a 288-pin, registered dual in-line memory module (RDIMM), with Dual-rank organisation and Supports ECC error detection and correction. In Table 3 of the module datasheet the row for this part number prints 32GB | 4 Gig x 72 | 25.6 GB/s | 0.62ns/3200 MT/s | 22-22-22. Procurement note: the manufacturer states below that every module part number carries a further two-place revision suffix, so bills of material should be reconciled with the manufacturer catalog before ordering.

Key figures

• Density and organisation: 32GB as 4 Gig x 72; the cover prints 32GB (4 Gig x 72) and the addressing table gives the DRAM devices as Base device: MT40A2G4.
• Data rate: PC4-3200 class, 3200 MT/s at tCK = 0.62ns; Table 3 prints the clock/triplet column as “0.62ns/3200 MT/s” with CAS-latency RCD-RP timing 22-22-22.
• Module bandwidth: 25.6 GB/s per the same row.
• Error protection: Supports ECC error detection and correction — the module carries x72 organisation (64 data plus 8 check bits).
• Ranks and banks: Dual-rank; 16 internal banks; 4 groups of 4 banks each.
• Supplies: VDD = 1.20V (NOM) with VPP and the SPD supply at 2.5V (NOM).
• Form factor: 288-pin, registered dual in-line memory module (RDIMM); the outline drawings give Module height: 31.25mm (1.23in).

Ordering and revision codes

Table 3 lists this part number as MTA36ASF4G72PZ-3G2. The own note of that table on enumeration is quoted verbatim: “All part numbers end with a two-place code (not shown) that designates component and PCB revisions. Consult factory for current revision codes.” The datasheet illustrates the complete form with the example “Example: MTA36ASF4G72PZ-3G2J3.” This page publishes the code the table prints and does not guess the revision suffix: we have no manufacturer module catalog entry on file for the other suffix combinations, so a suffix is not asserted here.

Temperature rating

The options-marking block of the datasheet lists the operating-temperature option as “Commercial (0°C ≤ T OPER ≤ 95°C)” with the marking field left unlabelled for that option. No reliability qualification standard and no grade certification appears anywhere in this document, so this page asserts none: the range is published as printed, nothing more.

Lifecycle status

The Lifecycle row above is left blank: the module datasheet states no product-status or end-of-life figure and we hold no manufacturer module-catalog row for this code to map one from, so we publish none rather than infer one.

Provenance

Every figure above is taken from the Micron module datasheet for the 32GB (x72, ECC, dual-rank) 288-pin DDR4 RDIMM, footer-marked “Rev. J 7/19 EN”. The copy is a channel-held local file and has not been byte-compared with a copy downloaded from the manufacturer, so the manufacturer datasheet button is left unpopulated and no direct PDF link is published.

Who makes it
