Product overview
This is the Kingston 64GB Kit DDR4 2133MHz ECC RDIMM Memory, order code KVR21R15D4K4/64. Registered, load-reduced and unbuffered modules are not interchangeable, and a board that accepts one will refuse to post on another. This module is ECC. Send the server model and we will check it against the supported-DIMM list before you order.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
The order is placed against KVR21R15D4K4/64, not against a description of it, so there is no room for a substitution you did not agree to.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
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 KVR21R15D4K4/64 genuine and is the warranty intact?
Yes, new and sealed, with the Kingston warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will KVR21R15D4K4/64 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, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

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.
