Server Memory Upgrade

This 4GB DDR3 1866 ECC RDIMM module is built for server and workstation systems that require registered memory with error correction. It operates at PC3-14900 speed with CL13 latency and 1.50V standard voltage. The single-rank 1Rx8 organisation uses major-brand chips for stable operation in compatible Dell platforms.

Compatibility Focus

The module is a direct replacement for Dell part numbers A7187320 and SNP7826WC/4G, removing guesswork when sourcing memory for those specific systems. Buyers who need different capacities, speeds or unbuffered DIMMs will not be served by this part. Verifying the motherboard's qualified-vendor list before purchase remains essential.

Build and Installation

A 240-pin DIMM form factor fits standard DDR3 server slots, while the registered design adds a buffer that reduces electrical load on the memory controller. ECC circuitry detects and corrects single-bit errors to protect data integrity in continuous workloads. Systems that require unbuffered or non-ECC memory cannot use this module.

Points forts

  • ECC protection prevents data corruption in servers
  • Registered design reduces electrical load on memory bus
  • 1866 MHz DDR3 speed supports demanding workloads
  • 4 GB capacity adds responsive multitasking headroom
  • 5 V standard voltage ensures broad compatibility

Questions sur cet article

Will the registered ECC DIMM need any firmware updates or chip replacements over its service life?

No firmware or chip replacements are required; the module uses major-brand chips tested to A-Tech quality standards and carries a lifetime warranty.

What limits sustained throughput on this CL13 1866 MHz registered module?

The CAS latency of 13 cycles at 1866 MHz sets the primary timing ceiling for continuous data transfers.

How much heat and power does a 1.5 V DDR3 RDIMM produce during all-day server operation?

At the standard 1.5 V DDR3 voltage the 4 GB module draws minimal power and generates low heat typical for registered DIMMs.
