This module operates at 1066MHz, also known as PC3-8500, with CL7 latency and a 4Rx8 quad-rank organization. It is registered ECC memory and uses 1.5V.

HYNIX HMT31GR77CFR8C-G7 Description

▼

The Hynix HMT31GR77CFR8C-G7 8GB 4Rx8 1066MHz DDR3 CL7 ECC is a high-performance memory module designed specifically for server and workstation environments where reliability and stability are critical. This 8GB DDR3 DIMM operates at 1066MHz with a CAS latency of 7, providing a balanced combination of speed and efficiency. Equipped with ECC (Error-Correcting Code) technology, it ensures data integrity by detecting and correcting memory errors, making it ideal for mission-critical applications, database servers, and enterprise-grade computing systems. The module’s 240-pin form factor ensures compatibility with a wide range of DDR3-compatible servers and motherboards supporting ECC memory.

Key specifications of this Hynix memory module include its 8GB capacity and 4Rx8 rank configuration, which contributes to improved performance and stability under heavy workloads. The 1066MHz memory speed is well-suited for systems requiring reliable DDR3 memory with moderate bandwidth needs. Its CL7 latency timing ensures low delay in data access, optimizing server responsiveness. The 240-pin DIMM format is standard for DDR3 modules, making installation straightforward in compatible systems.
