  • CL19 latency balances timing and stability

Server-ready 8 GB DDR4 module

This A-Tech registered DIMM delivers 8 GB of DDR4 2666 MHz memory with ECC error correction. The 2Rx8 organisation and 1.2 V operation suit enterprise servers and workstations that require registered modules. It plugs into standard 288-pin DDR4 slots.

Replaces Hynix HMA41GR7BJR8N-VK

The module is a direct equivalent for the Hynix HMA41GR7BJR8N-VK part number. The upgrade is worthwhile when a system currently runs below the PC4-21300 speed grade or lacks ECC protection for data integrity. CL19 latency matches the original specification.

Fits registered DDR4 platforms

Installation requires a motherboard that supports registered ECC DDR4 DIMMs at 2666 MHz. The single-module design leaves additional slots free for future capacity expansion. Verify the platform's qualified-vendor list before purchase to ensure compatibility.

商品問答

Will this 288-pin DDR4 DIMM fit my server motherboard?

The module uses the standard 288-pin DDR4 DIMM form factor, so it fits any server or workstation board that accepts DDR4 registered ECC memory.

What is the correct way to seat this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both side latches click, then verify the system detects the full 8 GB capacity at 2666 MHz in BIOS.

When should I consider replacing this 8 GB DDR4 2666 module?

Replace it if memory diagnostics report correctable or uncorrectable ECC errors, if the system fails to POST with the module installed, or when upgrading to a higher-capacity configuration.
