A-Tech 4GB DDR3 1600 ECC UDIMM 1Rx8 Server Memory

SKU CH-ATAF-SW4HG

4GB DDR3 1600 ECC unbuffered UDIMM with CL11 latency for server upgrades

  • Capacity4GB
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.50V
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • ECC protection safeguards data integrity with built-in error correction
  • DDR3 1600 speed delivers responsive server performance at PC3-12800 bandwidth

Compatible Replacement for Hynix HMT451E7BFR8C-PB

This A-Tech module is a 4GB DDR3 1600 ECC unbuffered DIMM built to replace the Hynix HMT451E7BFR8C-PB. It runs at PC3-12800 speed with CL11 latency at 1.50V and uses a 1Rx8 single-rank layout. The 240-pin form factor fits standard DDR3 server and workstation slots. Quality assurance testing and a lifetime warranty back the part.

Suits servers needing ECC UDIMM DDR3 1600

System builders maintaining DDR3 platforms that require error-correcting unbuffered memory at 1600 MHz will find this a direct fit. Buyers whose boards demand registered DIMMs, a different voltage, or higher density per slot cannot use this module. Compatibility must be verified against the system's qualified-vendor list before purchase.

Deciding spec: ECC unbuffered DDR3 1600 at 1.50V

The single specification that determines fit is the combination of ECC unbuffered operation, DDR3 1600 speed, and 1.50V voltage in a 240-pin DIMM. If the motherboard calls for registered ECC, a different voltage, or a non-ECC UDIMM, this module will not work. Match all three parameters to the system documentation.

Questions sur cet article

How do I install this 240-pin DDR3 DIMM and what is the common mistake?

Align the notch on the module with the key in the slot, press down firmly until both side clips click shut; the common mistake is stopping when it feels seated but before the clips engage.

What maintenance or replacement will this 4GB ECC UDIMM need later?

No scheduled maintenance is required; replace the module only if memory diagnostics report correctable errors that become uncorrectable or if a system upgrade demands higher capacity.

What limit appears first on this CL11 1.5V module under sustained load?

The 1600 MT/s data rate and CL11 latency set the throughput ceiling; sustained workloads will saturate bandwidth before the 1.5V thermal envelope becomes a constraint.
