  • Capacity128GB
  • 128 GB total capacity from four 32 GB modules
  • 2400 MHz DDR4 speed rated at PC4-19200
  • CL17 CAS latency for responsive server workloads
  • 288-pin RDIMM form factor fits registered DIMM slots
  • Validated for Dell PowerEdge R430, R530, R630, R730, R730XD, T430, T630, M630

128 GB DDR4 registered server kit

This Samsung bundle delivers 128 GB of DDR4 registered memory across four 32 GB RDIMMs. It runs at 2400 MHz with a CAS latency of CL 17 and uses the 288-pin form factor. The modules conform to the PC4-19200 standard and are sold new.

Compatible Dell PowerEdge servers only

The kit is validated for Dell PowerEdge M630, R430, R530, R630, R730, R730XD, T430 and T630 servers. Builders working with other vendors, consumer motherboards or unregistered DIMM slots should look elsewhere.

Registered DDR4 RDIMM at 2400 MHz

The decisive specification is that these are registered DDR4 RDIMMs operating at 2400 MHz with CL 17 timing. Systems requiring unbuffered UDIMMs, different speeds or lower latencies cannot use this kit.

Questions about this item

How do I install the four 32 GB RDIMMs in a Dell PowerEdge R730, and which slot order is the common mistake?

Populate the 288-pin DDR4 slots in the sequence shown in the server service manual — typically one DIMM per channel per CPU — and avoid filling all slots on one processor before the other.

What maintenance or replacement will the registered DDR4 kit need during its service life?

No routine maintenance is required; if a module fails the 128 GB kit must be replaced as a matched 4 x 32 GB set to keep CL 17 timing intact.

What limit appears first when the memory runs at 2400 MHz under sustained load?

The CL 17 latency and PC4-19200 bandwidth ceiling are reached before any thermal throttle on registered DDR4 modules.
