Server Memory
Registered ECC memory is not optional in a server. What varies is the speed grade, the rank configuration and whether the module is qualified for your platform — get any of those wrong and the machine either runs slow or will not post.
We list 289 parts across 12 brands — Crucial, Dell Technologies, HP, HPE, IBM, Intel, Kingston and Lenovo, plus 4 more, from $10 to $2,405 per unit. 285 are in stock and ship worldwide.
Browse by brand, capacity or interface below, or send us a part number and quantity. We source well beyond the published catalogue and quote within 48 business hours, with compatibility validated against your specific server platform before anything ships.
