Targeted Server Upgrade

This 32GB DDR5 4800 ECC Registered RDIMM is built for Gigabyte TO25-S10, TO25-S11, TO25-S12, TO25-Z10 and TO25-Z11 systems. It serves workstation, NAS, server and network switch platforms that require registered memory with error correction. Standard desktop computers cannot use this module.

Sustained Load Behaviour

JEDEC-standard timings at CL40 and 1.1V voltage maintain stability during continuous operation. ECC Registered architecture corrects single-bit errors in real time, preventing data corruption under heavy multi-tasking workloads. The 2Rx8 organisation supports consistent throughput for virtualisation and database tasks.

Installation Notes

The 288-pin DIMM seats in standard DDR5 RDIMM slots without a heat spreader to clear tight server chassis. Mixing with unbuffered or load-reduced ECC modules will prevent boot. Verify the target system model matches the listed Gigabyte TO25 series before ordering.

Questions about this item

How much power does the 1.1V DDR5 4800 module draw when the server runs continuously?

The module operates at 1.1V, which is the standard DDR5 voltage, keeping power draw low during all-day workloads.

What motherboard must I already have for this 288-pin ECC RDIMM to work?

It is validated for Gigabyte TO25-S10, TO25-S11, TO25-S12, TO25-Z10 and TO25-Z11 systems only.

Can I add this 2Rx8 registered DIMM alongside older unbuffered ECC sticks in my Gigabyte TO25?

No, registered memory cannot be mixed with unbuffered or load-reduced ECC modules.
