Product overview
The Lenovo 64GB DDR5-6400 PC5-51200 Server Memory is supplied under part number SM37B73342. A channel runs at the speed of its slowest module, so a faster part fitted alongside an older one buys nothing. This module is PC5-51200. Tell us what is already installed and we will keep the channel consistent.
Send a photo or a dump of the current DIMM layout and we will map the population for you before you order.

What you get ordering this from us
Ordered by part number
The order is placed against SM37B73342, not against a description of it, so there is no room for a substitution you did not agree to.
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.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
Is SM37B73342 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 SM37B73342 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.
