Memory for NEC Express5800 rack, tower, blade and fault-tolerant servers, matched to the NEC memory part number. This collection holds 80 listings covering 71 NEC part numbers, from DDR3 RDIMMs for b- through e-generation systems still in service to DDR5-6400 RDIMMs for the current R120k and the AMD EPYC R125k-2M. Every listing carries the NEC part number in its title and names the Express5800 models it fits.

The fastest way to your module: type the NEC part number (for example N8102-711 or N8102-772) into the search bar, or use the NEC Express5800 memory lookup, which lists every part number by generation with links to each listing.

Express5800 memory by generation

The lowercase letter in the model name is the generation, from b to m (NEC skipped l). 2nd-Gen and 3rd-Gen refreshes keep the model name but move to faster memory, so match the part number, not only the model.

Generation	Express5800 models	Memory
m	T110m, T110m-S, R110m-1	DDR5 ECC UDIMM (NEC spec DDR5-4400)
k	R120k-1M/2M, R110m-1M, R125k-2M, R110k-1	DDR5-6400 RDIMM; DDR4-3200 ECC UDIMM on the R110k-1
j	R120j-1M/2M, R110k-1M, T110k-M, R110j-1, T110j	DDR5-4800 and DDR5-5600 RDIMM; DDR4-2666 ECC UDIMM on the R110j-1 and T110j
i	R120i-1M/2M, T110i	DDR4-3200 RDIMM and LRDIMM; DDR4-2400 ECC UDIMM on the T110i
h	R120h, T120h, D120h, R120h-1M/2M (3rd-Gen), T110h	DDR4-2666 and DDR4-2933 RDIMM, DDR4-2666 LRDIMM; DDR4-2133 ECC UDIMM on the T110h
g	R120g, T120g, B120g, B120g-h, R320g	DDR4-2400 RDIMM and LRDIMM; DDR4-2666 RDIMM on the R320g
f	R120f, R120f-1E, T120f, E120f-M	DDR4-2133 RDIMM and LRDIMM
b–e	R120d, T120d, R120e, T120e, B120e, T120b-E	DDR3 RDIMM

Before you order

N8102 parts are for rack and tower servers, N8402 for B-series blades, N8802 for the R320 fault-tolerant series.
RDIMM, LRDIMM and ECC UDIMM do not mix, and DDR5 and DDR4 are keyed differently.
R125k-2M parts come as F and T pairs for the same module (for example N8102-F778 and N8102-T778); one listing covers both.
The DDR5 ECC UDIMMs for the T110m, T110m-S and R110m-1 are DDR5-5600 modules that run at the DDR5-4400 speed NEC specifies.
