Product overview
This is the IBM 64GB DDR3 1066MHz ECC registered CDIMM 1.5V 276p Memory, order code 46K2590. A channel runs at the speed of its slowest module, so a faster part fitted alongside an older one buys nothing. Tell us what is already installed and we will keep the channel consistent.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

Questions buyers ask about this part
Is 46K2590 genuine and is the warranty intact?
Yes, new and sealed, with the IBM warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will 46K2590 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.
