System-specific ECC kit for Dell Precision R5500

This OWC kit supplies 64 GB of DDR3 ECC registered memory in four 16 GB modules. It is built for the Dell Precision R5500 workstation and for other servers that require registered DIMMs. Standard desktop boards cannot use this memory because they lack support for registered signalling.

Registered DDR3 1333 CL9 at 1.5 V

Each module runs at DDR3 1333 (PC3-10600) with CAS latency 9 and a 1.5 V supply. The 2Rx4 organisation and 240-pin form factor match the R5500 memory controller requirements. Mixing these registered DIMMs with unbuffered modules will prevent the system from posting.

Steady throughput under continuous server workloads

ECC circuitry corrects single-bit errors on the fly while the registered buffer reduces electrical load on the memory bus. This combination keeps data integrity intact during long compute runs, virtualisation tasks or NAS duties. The JEDEC-compliant design sustains rated speed without throttling when all slots are populated.

Soalan tentang produk ini

How does the 1333MHz DDR3 speed translate in a Dell Precision R5500?

The kit runs at PC3-10600 1333MHz CL9, which is the native DDR3 speed the R5500 memory controller supports, so each 16GB module operates at its rated frequency without downclocking.

What does the 240-pin ECC Registered DDR3 interface cap in practice?

The 240-pin DDR3 ECC Registered DIMM interface limits the kit to DDR3 1333MHz bandwidth and requires a workstation or server motherboard that accepts registered modules; it will not work in standard desktop boards.

What physical clearance does the 240-pin RDIMM kit need inside the R5500?

Each module is a standard-height 240-pin DDR3 RDIMM without a heat spreader, so it fits the R5500 DIMM slots without extra vertical clearance beyond the stock latch mechanism.
