64GB DDR5-4800 ECC RDIMM
This A-Tech module supplies 64GB of DDR5 4800MHz registered ECC memory in a single 288-pin DIMM. It runs at the standard 1.10V and carries a CAS latency of 40. The 2Rx4 organisation uses major-brand DRAM ICs and is built as a compatible replacement for IBM-Lenovo part numbers 4X77A77033, 4X77A81442 and 03LA110.
Suited for servers needing registered ECC DDR5
The stick targets administrators upgrading or repairing systems that require DDR5-4800 RDIMM modules with ECC and registered buffering. Buyers whose platforms accept only unbuffered UDIMMs, a different DDR generation, or a lower density per module should select a different part.
Registered ECC with 2Rx4 layout
The registered ECC design combined with a 2Rx4 rank configuration is the specification that determines whether this module matches the memory controller and slot population rules of the target server.

이 상품에 대한 질문
Does the 288-pin DDR5 RDIMM ship as a single 64 GB module or do I need to buy extra sticks?
The package contains one 64 GB module; additional sticks are not included and must be purchased separately if your system requires more capacity.
Should I pick the 4800 MHz PC5-38400 version or a different speed grade for my Lenovo server?
This module runs at 4800 MHz (PC5-38400) with CL40 and 1.10 V, matching the specification for the listed Lenovo part numbers.
What does the 2Rx4 rank layout mean once the stick is installed in a real server?
The 2Rx4 organisation provides two ranks of x4 DRAM chips, allowing the memory controller to interleave accesses for higher bandwidth in registered ECC server platforms.
