Axiom 8 GB DDR3-1333 ECC RDIMM

This Axiom module is an 8 GB DDR3-1333 ECC registered DIMM built for server platforms. It operates at 1.35 V low voltage and runs at 1333 MHz with a PC3-10600 rating. The part is designed for HP Gen 8 systems and uses tier-one components on a 157.5 mil thick PCB.

Who this suits and who should look elsewhere

Administrators upgrading or repairing HP Gen 8 servers that require low-voltage DDR3 ECC registered memory will find guaranteed compatibility. Buyers who need higher capacity modules, faster speeds, or non-ECC unbuffered DIMMs for workstation or desktop boards cannot use this part.

DDR3-1333 ECC registered at 1.35 V

The module delivers 8 GB of DDR3-1333 ECC registered memory at 1.35 V. This specific combination of speed, voltage, error correction, and signal processing determines whether the DIMM matches the server's memory subsystem requirements.

Questions about this item

What speed does the DDR3-1333/PC3-10600 interface actually run at in a Gen 8 server?

The module operates at 1333 MHz, matching the DDR3-1333 standard; the server memory controller sets the final clock.

Will the 157.5 mil thick DIMM clear the heatsinks in an HP Gen 8 chassis?

At 157.5 mil (about 4 mm) the PCB fits the standard DIMM slot clearance used in Gen 8 servers.

Do I need to enable any BIOS setting for the 1.35 V ECC registered module to initialise correctly?

Insert the RDIMM with the server powered off; the BIOS detects ECC and registered operation automatically at 1.35 V.
