Target server module

This OWC 64GB DDR5 5600 CL46 2Rx4 288-pin 1.1V ECC Registered RDIMM is built for the Gigabyte G363-SR0 and G493-Series platforms. It delivers a single 64GB module rated at PC5-44800 with JEDEC-standard timings and voltage. The registered design and ECC function are intended for workloads that demand data integrity and sustained uptime.

Workstation and server builders only

This memory suits administrators upgrading compatible Gigabyte servers or workstations that require registered ECC DDR5. It will not operate in standard desktop mainboards, consumer laptops, or any system that accepts only unbuffered non-ECC modules. Builders needing load-reduced DIMMs or mixed-rank populations should verify platform qualifications before purchasing.

Registered ECC DDR5 requirement

The single specification that decides fitment is the registered ECC DDR5 interface; only platforms explicitly qualified for 288-pin RDIMM at 5600 MT/s with CL46 latency and 1.1V operation can use this module. Systems limited to UDIMM, LRDIMM, or different DDR generations cannot accept it.

商品問答

Will the 2Rx4 registered DIMM need any firmware updates or pairing when I add more modules later?

No firmware or pairing is required; each 64 GB DDR5 5600 CL46 2Rx4 registered module is JEDEC-compliant and installs independently in any supported slot on the Gigabyte G363-SR0 or G493 series.

What thermal limit appears first when the module runs at 5600 MT/s continuously in a dense server chassis?

The 1.1 V DDR5 DRAM reaches its maximum junction temperature before the registered buffer does, so sustained 5600 MT/s operation relies on adequate chassis airflow across the bare PCB.

How much power does a single 64 GB stick draw at 5600 MT/s under all-day load?

At 1.1 V the module draws roughly 5–7 W typical at 5600 MT/s, so a fully populated G493 system stays within standard DDR5 registered DIMM power envelopes.
