64GB DDR3 ECC Registered Kit

This OWC kit supplies 64GB of DDR3 1333 ECC registered memory in four 16GB modules. It is built for Dell PowerEdge R920, T410, T610 and T710 servers that require registered DIMMs with error correction. The modules will not work in standard desktop computers or alongside unbuffered memory.

JEDEC 1.5V 240-pin RDIMM

Each module uses a 240-pin RDIMM form factor at 1.5 volts and meets JEDEC PC3-10600 CL9 timing. The registered design adds a buffer that stabilises the memory bus in multi-socket server boards, while ECC detects and corrects single-bit errors during operation. No heat spreader is fitted, so airflow in the server chassis handles cooling directly.

Replaces lower-capacity RDIMMs

The 16GB-per-module density lets administrators reach 64GB with only four slots, freeing remaining slots for future expansion. It is a direct upgrade for systems running smaller registered DIMMs and avoids the incompatibility of mixing registered with unbuffered memory. Buyers who need unbuffered ECC or non-ECC desktop memory cannot use this kit.

Questions about this item

Does the PC3-10600 1333 MHz DDR3 interface limit bandwidth to 10600 MB/s in practice?

Yes, the DDR3 1333 PC3-10600 rating caps theoretical bandwidth at 10600 MB/s per module; real-world throughput is lower due to CL9 latency and controller overhead.

What physical slot and clearance does the 240-pin 1.5 V RDIMM need to fit in a Dell PowerEdge T610?

It requires a standard 240-pin DDR3 DIMM socket; the modules have no heat spreader, so low-profile heatsinks or tall CPU coolers will not interfere.

How are the four 16 GB 2Rx4 registered DIMMs installed, and which step is often missed?

Populate the matched-channel slots in the order shown in the server service manual, then verify in BIOS that all 64 GB are seen at 1333 MHz with ECC active; skipping the BIOS check is the common mistake.
