Green 16 GB DDR3 ECC registered DIMM module 157.5 mil thick

Axiom

Axiom 647883-S21-AX 16 GB DDR3-1333 ECC Registered DIMM 1.35 V

SKU CH-2EZB-YMZZ8 MPN 647883-S21-AX

16 GB DDR3 ECC registered DIMM running at 1333 MHz with 1.35 V operation

  • 16 GB capacity supports large workloads
  • DDR3-1333 speed delivers 1333 MHz data rates
  • ECC error checking protects data integrity
  • Registered signal processing stabilises heavy loads
  • 35 V low voltage reduces power draw

16 GB DDR3-1333 ECC Registered DIMM

The Axiom 647883-S21-AX is a 16 GB DDR3-1333 memory module built for HP Gen 8 servers. It uses ECC and registered signal processing to maintain data integrity in mission-critical environments. The module operates at a low 1.35 V to reduce power draw. System-specific testing guarantees compatibility with the validated platform.

DDR3-1333 PC3-10600 interface limits

The DDR3-1333 standard caps the data rate at 1333 MHz with a PC3-10600 bandwidth ceiling. Registered buffering adds a clock cycle of latency but allows larger memory populations per channel. Error-correcting code detects and corrects single-bit errors without halting the system. These traits define the practical performance envelope for this module.

157.5 mil thick PCB with tier-one components

A 157.5 mil thick printed circuit board uses tier-one components to meet stringent quality controls. The standard DIMM form factor ensures mechanical fit in supported HP Gen 8 slots. Lifetime warranty coverage reflects the manufacturer's confidence in long-term reliability. Consistent process controls support procurement policies that demand additional qualification testing.

Questions about this item

Should I pick the 16 GB DDR3-1333 ECC registered DIMM or a different capacity for my HP Gen8 server?

This module provides 16 GB in a single DIMM running at 1333 MHz with ECC and registered signal processing, matching the HP Gen8 specification listed for part 647883-S21-AX.

What does the 1333 MHz rating deliver once the DIMM is installed in a live system?

The module operates at 1333 MHz DDR3 speed with 1.35 V low-voltage supply, providing error-correcting registered performance for mission-critical workloads.

How does the DDR3-1333/PC3-10600 interface limit real-world throughput?

The DDR3-1333 standard sets the maximum clock at 1333 MHz; the registered ECC design adds one cycle of buffering, so sustained throughput stays within the PC3-10600 envelope.
