Dell XE9640 256GB DDR5 kit

This 256GB kit contains eight 32GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for the Dell PowerEdge XE9640 and runs at 1.10V. The modules use major OEM DRAM from Samsung, Micron or Hynix and are stress tested under load.

IT teams scaling XE9640 servers

The 8x32GB layout fills the XE9640 memory channels for maximum capacity. Buyers who need unbuffered UDIMMs or lower-density modules for other platforms should look elsewhere because this kit is registered ECC RDIMM only.

Standard 288-pin RDIMM installation

Insert each module into the server DIMM slots following the Dell service manual population rules. The most common issue is mixing registered and unbuffered DIMMs or skipping the required BIOS update, which prevents the system from recognising the full 256GB.

Spørgsmål om denne vare

Does the Dell PowerEdge XE9640 require all eight DIMM slots to be populated for this 256GB kit to operate?

The kit provides eight 32GB modules totalling 256GB; the XE9640 memory architecture determines whether partial population is supported, so consult the server manual for the approved slot layout.

Will these registered ECC RDIMMs work in a standard desktop motherboard that accepts unbuffered DDR5?

No, the modules are 288-pin DDR5 registered ECC RDIMMs built for server platforms and are not compatible with consumer desktop boards that require unbuffered memory.

How can I verify the memory is running at DDR5 4800 with CL40 latency after installation?

Enter the system BIOS or use a hardware utility such as CPU-Z to confirm the reported speed shows 4800 MT/s and the CAS latency reads CL40.
