System-Specific DDR5 RDIMM Kit

This 512GB kit contains four 128GB registered ECC modules built for Dell PowerEdge XE9780L and XE9785L rack servers. It runs at DDR5 5600 with a CL46 latency and operates at 1.1V. The 288-pin RDIMMs use 4Rx4 organisation and major OEM chips from Samsung, Micron or Hynix.

Suited for Qualified Dell Servers

The kit is validated for the two Dell PowerEdge models listed and will not fit consumer motherboards or workstations that require unbuffered DIMMs. Buyers who need non-ECC memory, lower capacities or different form factors should look elsewhere. Systems outside the specified Dell platforms are not supported by this part number.

4Rx4 Rank Determines Slot Population

Each module presents a 4Rx4 rank structure that the memory controller must recognise to initialise correctly. This rank configuration dictates how many modules can be installed per channel on the target Dell platforms. Verify the server's memory population rules against this 4Rx4 specification before ordering.

Questions about this item

Should I choose the 4x128GB kit or a different capacity for my Dell PowerEdge XE9780L?

The 512GB kit provides four 128GB modules to fill four slots, matching the 4Rx4 rank structure and 1.1V voltage required by the XE9780L and XE9785L platforms.

What does the DDR5 5600 CL46 rating deliver in a running server?

The modules operate at 5600 MT/s with a CAS latency of 46 cycles, giving registered ECC throughput of PC5-44800 bandwidth under standard 1.1V operation.

How does the 288-pin RDIMM interface limit speed and capacity in this system?

The 288-pin DDR5 RDIMM form factor locks the kit to 5600 MT/s and 128GB per module, with registered buffering and ECC required by the Dell PowerEdge XE9780L/XE9785L memory controller.
