64GB DDR5 ECC RDIMM for Gigabyte TO25 Servers

This OWC module delivers 64GB of DDR5 4800 memory in a 288-pin ECC Registered DIMM format. It is built for the Gigabyte TO25-S10, TO25-S11, TO25-S12, TO25-Z10 and TO25-Z11 platforms. The part is not compatible with standard desktop computers or unbuffered memory configurations.

Thermals and Power at 1.1V

Operating at 1.1V, the module follows JEDEC DDR5 standards for registered server memory. No heat spreader is fitted, so airflow in the chassis manages thermals. Power draw scales with the 4800 MT/s data rate and 2Rx4 organisation during typical workloads.

Upgrade Path from Smaller Registered Kits

The single 64GB stick replaces multiple lower-capacity registered DIMMs to simplify population rules. It suits administrators expanding memory in the listed Gigabyte TO25 models. Buyers needing unbuffered ECC or load-reduced modules should look elsewhere.

商品問答

How do I install the 288-pin DDR5 ECC RDIMM into a Gigabyte TO25-S10 server, and what step is often missed?

Power down the server, open the chassis, align the module key with the slot notch, press firmly until both retention clips click, then verify in BIOS that the 64GB module is detected at 4800 MT/s with ECC active.

What maintenance or replacement will the OWC 64GB DDR5 4800 CL40 module need over its service life?

No scheduled maintenance is required; keep air pathways clear so the 1.1V registered DIMM stays within thermal limits, and replace only if memory diagnostics report uncorrectable ECC errors.

What limit appears first when the 2Rx4 registered DIMM runs sustained workloads in a Gigabyte TO25-Z11?

The memory controller’s thermal throttle point is typically reached before the JEDEC-standard 4800 MT/s data rate or CL40 latency becomes a bottleneck.
