Narrowing 4,522+ results to one

Every listing title on this site is built the same way — capacity, generation, speed, PC code, rank, voltage, CAS latency, pin count, ECC and form factor, then the systems or OEM parts it is compatible with. Search matches against all of it, so each word you add cuts the list. DDR4 alone returns thousands; DDR4 3200 RDIMM 64GB returns the handful of 64GB modules at that speed; adding R750 leaves the ones listed for that server. Part numbers are the sharpest filter of all because each one appears on very few listings.

• Keep the dashes and slashes. P00922-B21 and SNP1V1N1C/16G are indexed as printed. Spaces in place of dashes will usually still match; dropping the suffix (P00922) matches, but loosely.
• One part number per search. Two part numbers in one box returns listings that carry either, which is broader, not narrower.
• Use the generation and form factor words together. DDR5 RDIMM, DDR4 SODIMM, DDR4 ECC UDIMM — the form factor is the field most often wrong on an order, and putting it in the search removes every module of the wrong type before you start reading.
• Spec strings work in either notation. DDR5-5600, DDR5 5600, 5600MHz, and PC5-44800 all find the same modules.
• Once results load, use the filters on the left — capacity, speed, form factor, and system model narrow further without retyping.

Reading a result title

64GB DDR5 5600MHz PC5-44800 2Rx4 1.1V CL46 288-PIN ECC RDIMM NEMIX RAM Server Memory Compatible with Dell PowerEdge R760 reads left to right as: capacity · generation · speed · JEDEC PC code · rank and DRAM width · voltage · CAS latency · pin count · ECC and form factor · the system or OEM part it is listed against. If the title's form factor and ECC words match what your system's documentation says, the module fits; the compatibility clause tells you it has been listed for that system specifically.

If a search returns nothing, or the wrong thing

• Check the part number for a transcription slip. Zero and the letter O, one and the letter I, and a dropped last character are the usual causes. Search the first two-thirds of the number and read the results.
• Try the system instead of the part, or the part instead of the system. A new part number may not yet be indexed against a listing that already fits it, and the reverse.
• Try the OEM's alternate number. Dell parts have a SNP code and a 370- code; HPE has an option (-B21) and a spare (-001 / -091); Lenovo has an option, a FRU, and a feature code; Cisco has a UCS-MR code and a Cisco-internal 15-xxxxx. The manufacturer pages decode each one.
• Check that the machine is upgradeable. Soldered laptops, Apple Silicon Macs, and ARM NAS units do not appear here because nothing fits them.
• Search by specification as the fallback. The Signature Series lists every module we build by spec, and most systems from a manufacturer we do not have a page for take one of them.

If none of that finds it, send us the part number or model and we look it up against the OEM's documentation and reply with the exact listing — and if the module does not exist yet in our catalog, we build it.
