A-Tech 4GB DDR3L 1333MHz ECC RDIMM 1Rx4 Server Memory

SKU CH-RKY5-Q56NZ

4GB DDR3L 1333MHz ECC registered DIMM for HP servers, 1.35V low-voltage operation

  • Capacity4GB
  • SpeedDDR3L 1333 (PC3L 10600)
  • CAS LatencyCL9
  • Voltage1.35V
  • ECCYes
  • Buffered/RegisteredRegistered
  • ECC protection guards data integrity with registered DDR3L design
  • Low 1.35V voltage reduces power draw in DDR3L modules
  • 1333MHz speed delivers PC3L-10600 bandwidth for server workloads
  • 240-pin DIMM form factor fits compatible HP server slots
  • 1Rx4 single-rank layout optimises memory controller efficiency

Product identity

This is a 4GB DDR3L registered ECC DIMM built for server and workstation platforms. It targets administrators who need to replace or expand memory in compatible HP systems using low-voltage modules.

Thermals noise power

The module operates at 1.35V, reducing power draw compared to standard DDR3 parts. Registered buffering and ECC circuitry add minimal heat under typical server workloads. No active cooling is required on the module itself.

Build fit

The 240-pin DIMM fits DDR3L slots that support registered ECC memory. It frees a single slot for a 4GB capacity increase. Buyers needing higher densities or non-ECC unbuffered memory should look elsewhere.

Highlights

  • ECC protection guards data integrity with registered DDR3L design
  • Low 1.35V voltage reduces power draw in DDR3L modules
  • 1333MHz speed delivers PC3L-10600 bandwidth for server workloads
  • 240-pin DIMM form factor fits compatible HP server slots
  • 1Rx4 single-rank layout optimises memory controller efficiency

Questions about this item

How do I install this 240-pin DDR3L RDIMM and which orientation mistake should I avoid?

Align the notch on the module with the key in the slot, press straight down until both clips snap shut, and never force it backwards — the single notch only fits one way.

What maintenance or replacement will this ECC registered module need over time?

No routine maintenance is required; if a correctable error count rises or the module fails, replace the 4GB stick with an identical DDR3L 1333MHz 1Rx4 RDIMM.

What limit appears first when this 1.35V registered DIMM runs sustained workloads?

The 1333MHz data rate and CL9 latency set the throughput ceiling before voltage or thermal limits become a factor.
