Server Memory Upgrade
This A-Tech module delivers 128GB of DDR4 2666MHz registered ECC memory in a single 288-pin DIMM. It is built for servers and workstations that require error-correcting, buffered modules to maintain data integrity under heavy workloads. The 2S4Rx4 organisation with 3DS/TSV stacking enables this high density on one stick.
Registered ECC Design
The module operates at the standard 1.2V DDR4 voltage with CL19 latency and a registered buffer that reduces electrical load on the memory controller. Registered ECC RDIMM architecture suits multi-socket platforms where signal integrity and error detection are critical for uptime. A 262-pin form factor matches the mechanical slot specification for compatible systems.
Capacity Expansion Path
This part replaces IBM-Lenovo 7X77A01307 and 01DE977 modules, letting administrators add 128GB per slot without populating multiple lower-density DIMMs. The jump is worthwhile when the platform supports 3DS/TSV registered DIMMs and the application benefits from fewer occupied slots for future scaling. Buyers needing non-ECC unbuffered memory or lower voltages should look elsewhere.

คำถามเกี่ยวกับสินค้านี้
What speed does the DDR4 2666 interface cap at in practice?
The module runs at DDR4 2666 (PC4-21300) with CL19 latency, so the practical data rate is 2666 MT/s.
What physical slot and pin count does this 288-pin DIMM require?
It fits a standard DDR4 DIMM slot with 288 pins; the form factor is listed as DIMM (262 Pin) in the specifications.
How is the module installed and what step do people often miss?
Align the notch on the 288-pin DIMM with the slot key, press firmly until both side clips click, and verify the system recognises the full 128GB capacity.
