Lenovo 4X77A93556 memory module 16 GB 1 x 16 GB DDR5 288-pin DIMM ECC

Product Overview

AI-generated summary

At ~£1,164 ex-VAT for a single 16GB DDR5 ECC DIMM, this Lenovo-branded 16GB stick is priced like it’s being sold for a very specific, pre-approved server spec or through an OEM channel. For most UK SME rebuilds and “top up what’s already there” upgrades, that’s a hard sell: the cost per GB is simply too high, and you’ll almost certainly find cheaper compatible ECC DDR5 modules elsewhere (as long as you match the server’s supported speeds/rank requirements). Unless you’re tied to Lenovo part numbers for warranty/compatibility paperwork, you’re paying a premium you may not need.

Who *should* buy it: organisations running Lenovo servers where the service/warranty terms, management tooling, or vendor contracts effectively require OEM memory, and where the machine is picky about exact module characteristics. Who *shouldn’t*: anyone doing cost-sensitive expansion, homelab-style upgrades, or “generic compatibility” installs—there, this price makes me suspect you’d get better value by sourcing equivalent ECC DDR5 from a reputable supplier and only using OEM if you hit a compatibility issue.

If you tell me the server model (and what RAM you already have), I can help you sanity-check whether paying this premium is actually warranted.
