Axiom 713979-S21-AX 8GB DDR3-1600 ECC UDIMM server RAM

SKU CH-TGSX-1QWFM MPN 713979-S21-AX

8 GB DDR3 ECC UDIMM running at 1600 MHz with 1.35 V low voltage for HP 713979-S21-AX servers

  • 8 GB capacity supports larger server workloads
  • DDR3-1600 speed delivers 12800 MB/s bandwidth
  • ECC protection detects and corrects memory errors
  • 35 V low-voltage operation reduces power draw
  • 5 mil slim profile fits dense DIMM slots

8 GB DDR3 ECC UDIMM for servers

This 8 GB DDR3 ECC UDIMM operates at 1600 MHz with a low 1.35 V voltage. It is built for HP systems that require registered error correction and unbuffered signalling in a standard DIMM form factor.

157.5 mil PCB with tier-one components

The module uses a 157.5 mil thick printed circuit board assembled with tier-one DRAM and PCB materials. Standard DIMM edge connectors ensure direct installation in compatible server slots without adapters or riser cards.

Low-voltage DDR3 thermals and power draw

Running at 1.35 V reduces heat output and power consumption compared to standard 1.5 V DDR3 modules. The unbuffered design adds minimal electrical load, helping maintain stable temperatures in densely populated memory banks. Not suited for platforms that require registered or load-reduced DIMMs, or for systems limited to 1.5 V memory only.

Questions about this item

What throughput does the DDR3-1600/PC3-12800 standard provide for this module?

The PC3-12800 designation corresponds to the DDR3-1600 speed rating of 1600 MHz for this 8 GB ECC UDIMM.

Will this 157.5 mil thick DIMM fit my server's memory slots?

The module uses the standard DIMM form factor at 157.5 mil thickness, matching regular UDIMM slot dimensions in compatible systems.

How do I install this ECC UDIMM and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the system recognises the full 8 GB and ECC function in BIOS.
