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 about this item
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.
