Server-grade DDR4 module

This 128GB DDR4 3200 PC4-25600 CL22 ECC Registered RDIMM is built for workstations and servers that require registered memory with error correction. It operates at 1.2V and carries a 288-pin form factor compatible with specific TYAN motherboards and the Thinkmate RAX QN24-22E7 system. The single-module design delivers high capacity in one slot.

Suited for registered ECC platforms only

This module fits administrators upgrading compatible TYAN S7120 or S8030 series boards or the listed Thinkmate server. It will not work in standard desktop computers or any system that requires unbuffered memory. Builders needing load-reduced DIMMs or non-ECC consumer RAM must choose a different product type entirely.

128GB density in a single rank-8 stick

The 8Rx4 organisation packs 128GB into one registered DIMM, maximising capacity per slot on qualified platforms. Verify your motherboard supports this rank configuration and total capacity before purchase, as registered ECC modules cannot be mixed with unbuffered or load-reduced memory in the same system.

Questions about this item

How do I install the 288-pin ECC RDIMM and what step is often missed?

Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify the system registers 128GB at 3200MHz — the step often missed is confirming the BIOS recognises the registered ECC type rather than treating it as unbuffered memory.

What maintenance or replacement will this 128GB DDR4 module need over time?

No routine maintenance is required for the DDR4 RDIMM; replacement only becomes necessary if a memory test reports correctable ECC errors that exceed the platform threshold or if a capacity upgrade demands a different rank configuration.

What limit appears first when this 8Rx4 module runs sustained workloads at 1.2V?

The thermal limit of the 8Rx4 organisation typically appears first; dense rank packing generates more heat per DIMM, so sustained 3200MHz operation relies on adequate chassis airflow to prevent throttling.
