NEC Express5800 Server Memory by NEC Part Number: N8102, N8402 and N8802
Memory for NEC Express5800 rack, tower, blade and fault-tolerant servers, matched to the NEC memory part number. NEMIX RAM lists 71 NEC part numbers across the Express5800 b through m generations, from DDR3 RDIMMs for systems still in service to DDR5-6400 RDIMMs for the current R120k and R125k. Type the NEC part number (for example N8102-711) into the search bar at the top of the page, find it in the tables below, or browse all NEC Express5800 memory.
Find your NEC part number first
NEC sells Express5800 memory under its own part numbers: N8102 for rack and tower servers, N8402 for B-series blades and N8802 for the R320 fault-tolerant series. The part number is in the system configuration guide for your model and on the order or asset record for the server. Each NEMIX RAM listing carries the NEC part number in its title and names the Express5800 models it fits. The R125k-2M parts come as F and T pairs for the same module, for example N8102-F778 and N8102-T778; one NEMIX RAM listing covers both.
How the Express5800 generations work
The lowercase letter in the model name is the generation: R120h-1M is an h-generation 1U rack server, T120h its tower sibling. NEC uses b, d, e, f, g, h, i, j, k and m; there is no l generation. Several generations have 2nd-Gen and 3rd-Gen refreshes that keep the model name but move to faster memory, so the 3rd-Gen R120h-1M takes DDR4-2933 where the first R120h took DDR4-2666. Check the part number, not only the model.

Rules that apply across Express5800 servers
- Match the module type. RDIMM, LRDIMM and ECC UDIMM do not mix. Rack servers take registered RDIMM or load-reduced LRDIMM; the T110 and R110 entry systems take ECC UDIMM.
- Do not mix RDIMM and LRDIMM in the same server, and keep all modules in a channel the same capacity and rank.
- DDR5 and DDR4 are keyed differently and will not fit each other's slots.
- Faster modules run at the system speed. NEC specifies DDR5-4400 ECC UDIMM for the T110m, T110m-S and R110m-1; the NEMIX RAM modules for those parts are DDR5-5600 ECC UDIMMs and run at 4400 MT/s in those systems.

Data centers, enterprise IT and service providers
Express5800 servers keep running long after NEC stops listing their memory options. Purchase orders, net terms and volume pricing are available for enterprise IT, service providers, system integrators, schools and government buyers. Request a quote for a fleet upgrade, or send us your NEC part numbers and Express5800 models and we will confirm the right module before you order.
Frequently asked
My server model is listed under two parts with the same capacity. Which do I need?
Some generations offer the same capacity in two ranks, for example N8102-721 (16GB single-rank) and N8102-722 (16GB dual-rank) for the 3rd-Gen R120h. Match the part number already installed, or the one in your configuration guide.
Can I mix NEMIX RAM modules with the NEC modules already installed?
Yes, if the module matches the installed NEC part in type, speed, capacity and rank. For a new population, use identical modules throughout.
Is the 256GB N8102-776 available?
No. NEMIX RAM does not offer a 256GB DDR5 module for the R120k-2M. The 128GB N8102-775 is the largest NEC R120k module listed here.
My part number is not listed. Can you still help?
Yes. Send us the part number and server model and we will check it against our range.
