System-specific DDR5 kit

This NEMIX RAM kit supplies 256GB across four 64GB registered DIMMs built for Dell PowerEdge XE9780L and XE9785L rack servers. It targets administrators who need maximum capacity in qualified slots without mixing module densities.

DDR5 5600 registered ECC limits

The modules run at DDR5 5600 with a CAS latency of CL46 and require a platform that supports registered ECC RDIMMs at 1.1V. Systems limited to lower speeds, unbuffered DIMMs or non-ECC memory cannot use this kit.

4Rx4 quad-rank density

Each DIMM uses a 4Rx4 organisation, so the memory controller must accept quad-rank registered modules to address the full 64GB per slot. Platforms restricted to dual-rank or single-rank DIMMs will not recognise the full capacity.

Questions about this item

Should I pick the 256GB kit or a smaller capacity for my Dell PowerEdge XE9780L?

The 256GB kit provides four 64GB modules for maximum supported density in the Dell PowerEdge XE9780L and XE9785L.

What does the 5600 speed rating deliver in my server?

DDR5 5600 (PC5-44800) runs at 5600 MT/s, giving the peak bandwidth the platform specifies for these Dell PowerEdge rack servers.

How does the 288-pin ECC RDIMM interface limit performance?

The 288-pin registered ECC DDR5 interface caps operation at 1.1V with CL46 latency and 4Rx4 organisation for stability in the Dell PowerEdge XE9780L and XE9785L.
