Product overview

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 64GB module. Send the current layout and we will map the slots for you.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

What you get ordering this from us
Ordered by part number
The order is placed against 311-7997, 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.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
- Is 311-7997 genuine and is the warranty intact?
- Yes — new and sealed, with the Dell warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will 311-7997 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.
