Samsung 256GB DDR4 RDIMM Kit

This kit provides 256GB of DDR4 server memory across eight 32GB registered DIMMs running at 2666MHz with CL19 latency. It is built for Dell PowerEdge servers including the M640, R440, R540, R640, R740, R740XD, T440 and T640 models. The 288-pin RDIMM form factor and registered design suit multi-socket platforms needing high capacity.

Installation Notes

Each module seats in a standard 288-pin DDR4 slot; the registered buffer adds a small electrical load that the memory controller must support. Mixing registered and unbuffered DIMMs will prevent boot, so populate all channels with identical RDIMMs. Verify the server firmware is current before adding the full 256GB kit to avoid memory training failures.

Pre-Purchase Checks

Confirm your Dell PowerEdge model appears in the supported list: M640, R440, R540, R640, R740, R740XD, T440 or T640. Check how many DIMM slots are free and whether the CPU configuration allows eight modules per processor. Ensure the existing memory runs at 2666MHz CL19; mismatched speed or latency will force the system to the lowest common settings. Buyers needing unbuffered UDIMMs or a different capacity per module should look elsewhere.
