Axiom 8GB DDR3 1333 ECC Unbuffered DIMM

This Axiom module provides 8GB of DDR3 SDRAM rated at 1333 MHz (PC3-10600) with a low 1.35V operating voltage. It uses a 240-pin DIMM form factor and includes Error Correcting Code for data integrity. The unbuffered design suits servers that do not require registered memory.

Fits Dell PowerEdge M620, R620, T110 II.

The memory is validated for these specific Dell PowerEdge systems. Administrators maintaining or upgrading those platforms can install this module with confidence. Servers outside this validated list or workloads needing registered DIMMs should evaluate other options.

DDR3 1333 unbuffered ECC at 1.35V

The single specification that determines fit is the combination of DDR3 1333 speed, unbuffered signal processing, ECC support and 1.35V voltage. A motherboard must accept all four attributes for the module to function correctly.

Questions about this item

Does this 240-pin DDR3 module need a server motherboard with ECC support to work?

Yes, the module is ECC unbuffered DDR3-1333 at 1.35V, so the motherboard must accept unbuffered ECC DIMMs and run at PC3-10600 speed.

Can I add this 8 GB stick alongside existing 4 GB DDR3-1333 modules in my PowerEdge R620?

The R620 supports mixed capacities per channel, but all DIMMs must be unbuffered ECC at 1.35V; matching speed and voltage lets the system run at 1333 MHz.

How do I confirm the module is running at 1333 MHz with ECC active after installation?

Check the BIOS memory information or run dmidecode — it should show 1333 MHz, PC3-10600, 1.35 V and ECC enabled for the A5185893-AX DIMM.
