Dell PowerEdge R6625 R760 R7615 R7625 Compatibility

This 256GB kit contains two 128GB DDR5 4800 CL40 ECC Registered RDIMM modules. It is built for Dell PowerEdge R6625, R760, R7615 and R7625 servers. The memory targets IT teams expanding capacity in these specific 1U and 2U rack platforms.

Registered ECC DDR5 Interface Limits

Registered ECC DDR5 modules require a server chipset that supports registered signalling and error correction. They will not function in standard desktop motherboards or consumer laptops. Mixing these DIMMs with unbuffered or load-reduced memory is not supported and will prevent boot.

4Rx4 Rank Density Determines Fit

Each 128GB module uses a 4Rx4 organisation, delivering high density per slot. The server memory controller must support 4Rx4 ranks at DDR5 4800 to recognise the full 256GB. Systems limited to lower rank counts or slower speeds cannot use this kit.

Pontos fortes

Perguntas sobre este artigo

Should I buy the 256GB kit or look for a different capacity?

This kit provides 256GB total using two 128GB modules, matching the listed part number 4R8D54R4256P.

What does the 4800MHz speed mean once installed in a PowerEdge server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, delivering the rated throughput when the server memory controller operates at that speed.

Will the 288-pin ECC Registered RDIMM interface work in my R760?

Yes, the 288-pin DDR5 ECC Registered RDIMM form factor is designed for the Dell PowerEdge R6625, R760, R7615 and R7625 and cannot be mixed with unbuffered or load-reduced memory.
