Product overview
M393A4K40EB3-CWE is a Samsung 32GB DDR4-3200 ECC registered RDIMM 2Rx4 288-Pin Server Memory Module. Population order decides whether you get the full memory bandwidth or a fraction of it, and the rules change between one and two processors. This is a 32GB module. Send the current layout and we will map the slots for you.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

What you get ordering this from us
Ordered by part number
Quoted and supplied against M393A4K40EB3-CWE specifically, so what arrives is what your build sheet asks for.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Rank and voltage confirmed
We check rank, voltage and module type against the platform before quoting, which is where most memory orders go wrong.
Questions buyers ask about this part
Is M393A4K40EB3-CWE genuine and is the warranty intact?
Yes, new and sealed, with the Samsung warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will M393A4K40EB3-CWE 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
