384GB DDR4 2933MHz ECC RDIMM Kit

This 384GB kit contains six 64GB DDR4 2933MHz registered DIMMs built for enterprise servers. Each module operates at 1.2V with a CAS latency of 21 and a 4Rx4 organisation. The kit targets administrators upgrading memory capacity in compatible 288-pin DDR4 server platforms.

4Rx4 Registered ECC Organisation

The 4Rx4 rank configuration and registered buffer determine whether this kit works in a given server. Only systems that support 4Rx4 registered ECC DDR4 2933MHz modules can use this memory. Standard desktop or workstation boards that accept only unbuffered UDIMMs or lower-rank RDIMMs will not be compatible.

Major OEM Samsung Micron Hynix Chips

Modules are assembled with DRAM from Samsung, Micron or Hynix depending on supply. This multi-source approach does not change the rated speed, voltage, latency or ECC function. Buyers receive a tested kit that meets the stated DDR4 2933MHz PC4-23400 specification regardless of the underlying chip vendor.

Questions about this item

What does the 2933 MHz speed mean when the modules are installed in a server?

The modules run at 2933 MHz when the memory controller and platform support that data rate; otherwise they operate at the highest supported speed.

What does the PC4-23400 designation indicate for this memory?

PC4-23400 is the DDR4-2933 standard name used for module labelling and ordering.

What physical slot and pin count do these RDIMMs require?

Each module uses a 288-pin DDR4 RDIMM form factor and fits standard 288-pin registered DIMM slots.
