Capacity and purpose

This kit provides 128GB of DDR4 ECC registered memory in two 64GB modules. It is built for servers and workstations that need large-capacity, error-correcting RAM for virtualisation, database or compute workloads.

Compatibility check

Verify that your motherboard accepts 4Rx4 registered DIMMs at DDR4 3200 and that the memory controller supports the total 128GB capacity. Confirm the 288-pin RDIMM form factor matches your board's slots and that no BIOS limitation restricts quad-rank modules.

Sustained load behaviour

Rated at CL22 and 1.2V, the modules are stress-tested under load to maintain stability during prolonged operation. The registered buffer and ECC function reduce electrical load on the memory controller and correct single-bit errors, helping prevent data corruption in continuous server duty.

Questions about this item

Does the kit include both 64 GB modules or do I need to buy a second stick?

The package contains two 64 GB RDIMMs giving 128 GB total, so no extra modules are required.

Should I choose the 4Rx4 registered version or a different rank for my Tyan board?

This kit is 4Rx4 registered ECC DDR4 3200, matching the specification for the compatible Tyan system.

Will the CL22 latency at 3200 MT/s run at that speed once installed in the server?

The modules are rated DDR4 3200 PC4-25600 CL22 at 1.20 V and will operate at that speed when the platform supports it.
