128GB DDR5 ECC UDIMM kit for ASUS motherboards

This 128GB kit contains four 32GB DDR5 4800 modules built for ASUS Prime and Pro series boards. ECC unbuffered operation suits workstations and NAS devices that need error correction without registered memory. The 1.1V modules run at CL40 latency and use 288-pin UDIMM form factor. Builders who need non-ECC or registered DIMMs should look elsewhere.

Sustained workload stability from stress-tested

Each module undergoes rigorous load testing before shipment to verify reliability under continuous enterprise workloads. The 2Rx8 organisation and Samsung, Micron or Hynix chips provide consistent throughput for virtualisation, ZFS storage or rendering tasks. ECC corrects single-bit errors in flight, preventing silent data corruption during long runs. Systems without ECC support in the BIOS will not benefit from the error-correction capability.

Straightforward four-module installation

The kit drops into four 288-pin DDR5 slots on compatible ASUS A620, B650 and Q670 micro-ATX models listed by the manufacturer. No heat spreader means low-profile clearance for compact coolers. Installers must populate all four slots for the rated 128GB capacity and ensure the BIOS recognises ECC unbuffered mode. Boards limited to two DIMM slots or requiring registered memory will not accept this configuration.

Questions about this item

How much heat or power does the 1.1V DDR5 4800 kit draw when the system runs all day?

The modules operate at 1.10 V and carry no heat spreader, so thermal output is limited to the standard DDR5 4800 power envelope for 2Rx8 unbuffered ECC UDIMMs.

Which motherboard slots and chipsets must I already have for this 288-pin kit to work?

You need a motherboard with four DDR5 UDIMM slots and a chipset such as A620, B650 or Q670 that supports 2Rx8 ECC unbuffered memory at 4800 MT/s.

Will the CL40 2Rx8 modules run alongside older DDR5 sticks I keep in the other slots?

Mixing ranks or latencies can prevent the board from training at 4800 MT/s; for stability, populate all four slots with this matched 128 GB kit rather than combining it with different modules.
