Hynix HMT451U6BFR8C-PBN0AA 4GB

Product Description

Hynix (SK Hynix) 4GB DDR4 ECC Registered RDIMM

This Hynix HMT451U6BFR8C-PBN0AA is a 4GB DDR4 server memory module with ECC. As a 1Rx8 (Single Rank, x8) Registered RDIMM operating at 2666MHz, it is a very low-density component for the DDR4 platform. Its primary value is for exact-match replacement in specific server models that were originally configured with 4GB modules, or for specialized applications requiring many low-capacity DIMMs to maximize channel population.

Key Specifications:

• Capacity: 4GB

• Type: DDR4 SDRAM with ECC

• Speed: 2666 MHz (PC4-21300R)

• Voltage: 1.2V

• Module Type: 288-pin ECC Registered DIMM (RDIMM)

• Organization: 1Rx8 (Single Rank, x8)

• Part Number: HMT451U6BFR8C-PBN0AA

Compatibility & Applications:

• Target Systems: May be found in some Dell PowerEdge 14G (R640/R740), HPE ProLiant Gen10, or OEM whitebox servers that shipped with minimal base memory for certain markets or applications.

• Primary Use: Strictly for repair or niche configurations. Replacing an identical failed module in a system where upgrading density is not desired or possible, or for technical configurations requiring many single-rank modules.

• Note: 4GB is an exceptionally low and uncommon capacity for 2666MHz DDR4. This module is not intended for performance upgrades but for maintaining original specifications in legacy DDR4 deployments.
