Lenovo 4X77A88511 memory module 16 GB 1 x 16 GB DDR5 288-pin DIMM ECC

Product Overview

AI-generated summary

At £1,279.58 ex-VAT for a single 16GB DDR5 ECC module, this is an easy “pause and verify” purchase. Realistically, most buyers should expect that kind of money to go toward a whole matched upgrade kit (or at least multiple sticks / higher-capacity options). If you only need one stick to replace a failed DIMM, the price can make sense in a repair scenario—but you should be very sure you’re not paying “special part” pricing when a cheaper equivalent would be compatible in your server.

I’d recommend this only if you’ve got a Lenovo server that’s been picky about memory compatibility and you need genuine Lenovo ECC DDR5 to avoid weird boot/POST issues, and you’re genuinely sourcing a like-for-like replacement (same spec, speed grade, and rank the platform expects). If you’re doing a planned capacity increase rather than a replacement, look at better value options first—matched sets and lower-cost qualified alternatives usually give you far more usable capacity per pound. Bottom line: buy it if it’s a targeted Lenovo replacement you can’t afford to get wrong; otherwise, at this price, I’d be shopping around before committing.
