OWC 32GB DDR3 ECC Registered RDIMM

This OWC module is a single 32GB DDR3 1600 PC3-12800 CL11 4Rx4 240-pin 1.5V ECC Registered DIMM. It is designed as a system-specific upgrade for compatible Supermicro motherboard series including H8DGG, H8QG6, H8QGI, H8SGL and X9DA7. The part meets JEDEC and RoHS standards for warranty-safe installation in servers and workstations.

For servers needing registered ECC; not for desktops

This memory suits administrators extending the life of supported Supermicro platforms or building new server infrastructure with registered ECC modules. It will not work in standard desktop computers that require unbuffered memory, and it cannot be mixed with unbuffered modules on the same board. Buyers needing non-registered ECC for entry-level workstations should select a different module type.

Registered ECC with 4Rx4 organisation

The module uses registered ECC technology with a 4Rx4 rank configuration, which is the key specification determining compatibility with the listed Supermicro motherboards. Systems that require registered error-correcting memory with this exact rank structure will accept the upgrade, while platforms limited to unbuffered memory will not. Verify the motherboard manual calls for registered 4Rx4 DDR3 before purchase.

Questions about this item

What does the 32 GB capacity mean for a server running virtual machines?

A single 32 GB registered DIMM adds a large chunk of ECC-protected memory, letting the host run more concurrent VMs or larger datasets without swapping to disk.

How does the DDR3 1600 PC3-12800 rating translate to real throughput on a Supermicro X9DA7 board?

The memory operates at 1600 MHz with CL11 timing, matching the board's native DDR3 1600 controller for full rated speed.

Will the 240-pin 1.5 V registered form factor fit the H8DGG series memory slots?

Yes, the module uses the standard 240-pin DDR3 RDIMM keying and 1.5 V voltage required by those Supermicro motherboards.
