A-Tech 4GB DDR3 1333 ECC RDIMM 2Rx8 Server Memory

4GB DDR3 1333 ECC RDIMM Server Memory

This 4GB DDR3 1333 ECC RDIMM module provides registered, error-correcting memory for server and workstation platforms. It operates at PC3-10600 speed with CL9 latency and standard 1.5V voltage. The 2Rx8 dual-rank organisation uses major-brand chips on a 240-pin DIMM. It serves as a direct replacement for HP part numbers 500658-B28 and 654559-888.

Suits servers needing registered ECC DDR3 capacity

This module fits systems that require registered ECC DDR3 DIMMs at 1333 MHz. Builders whose platforms accept only unbuffered non-ECC memory or a different DDR generation cannot use this part. Systems limited to single-rank modules or a lower voltage standard also fall outside its specifications.

Registered ECC with 2Rx8 organisation

The registered buffer and ECC function together with the 2Rx8 rank structure determine whether the memory controller can initialise the module. Verify that your motherboard or server documentation explicitly supports registered ECC DDR3 DIMMs with dual-rank 2Rx8 layout before purchase.
