Product overview
This is the Lenovo ThinkSystem 128GB TruDDR4 performance+ 2933MHz (4Rx4 1.2V) 3DS RDIMM Server Memory Module, order code 4X77A12187. Registered, load-reduced and unbuffered modules are not interchangeable, and a board that accepts one will refuse to post on another. This module is RDIMM. Send the server model and we will check it against the supported-DIMM list before you order.
No price is published here because the market for this part moves week to week; ask and we will give you a current one rather than a stale one.

What you get ordering this from us
Ordered by part number
4X77A12187 is what is quoted and 4X77A12187 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Questions buyers ask about this part
- Is 4X77A12187 genuine and is the warranty intact?
- Yes — new and sealed, with the Lenovo warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will 4X77A12187 work in my server?
- Send the server model and a list of the DIMMs already fitted. Rank, voltage and population order all have to agree, and a module that is electrically compatible can still be unsupported in a given slot. We map the population before you order.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
Host memory on an AI node is normally sized against accelerator memory, so the model and its working set both fit.
