OWC 16GB DDR3 1333 ECC Registered RDIMM

This OWC memory module delivers 16GB of DDR3 1333 (PC3-10600) capacity in a single 240-pin registered DIMM. It operates at CL9 latency with a standard 1.5V supply and includes on-board ECC for data integrity. The 2Rx4 dual-rank organisation suits server and workstation platforms that require registered memory.

Targeted at Supermicro SuperServer operators

The module is validated for Supermicro SuperServer 1026GT, 1026T, 1026TT, 2026TT and 6016GT series systems. It will not work in standard desktop computers that accept only unbuffered non-ECC memory. Buyers who need unbuffered DIMMs for consumer motherboards should look at a different product line.

Registered ECC DDR3 240-pin form factor

This stick uses the registered ECC DDR3 240-pin interface, which is electrically incompatible with unbuffered desktop slots. The single specification that decides fit is the registered ECC DDR3 240-pin form factor; only systems designed for that exact memory type will accept it.

Questions about this item

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

The module operates at 1333 MT/s with CL9 latency at 1.5 V, matching the PC3-10600 JEDEC rating for registered ECC DIMMs.

Will the 240-pin registered DIMM fit the Supermicro 1026GT, 1026T, 1026TT, 2026TT or 6016GT memory slots?

Yes, the 240-pin DDR3 RDIMM form factor is the exact slot type used across all listed Supermicro SuperServer series.

How do I install the 16 GB 2Rx4 RDIMM without triggering a memory error?

Power off the server, open the chassis, align the notch on the 240-pin edge connector with the key in the slot, press firmly until both retention clips click, then power on and verify the full 16 GB appears in BIOS.
