Questions buyers ask about this part
Should I take the 16GB or the 8GB?
Same part, different capacity: identical specification and RDIMM DIMM. The 8GB gives you less capacity at a lower unit cost. Where the constraint is the number of slots rather than the budget (a board already fully populated, or a platform at its supported maximum), the larger part is usually the cheaper way to the same total. Ask us for both on one quote and compare.
Is this IBM part genuine, and is the warranty intact?
Yes. We supply through authorized distribution only, so the part carries the full IBM manufacturer warranty and its firmware update path stays supported. No grey-market stock, no re-labelled drives, no voided warranties.
Do you offer volume pricing and accept purchase orders?
The listed price is per unit and indicative; tiered pricing applies at quantity. We accept purchase orders from qualified businesses, government and defence agencies, and educational institutions, with net terms and consolidated invoicing available. Email the quantity you need and we will come back within 48 business hours.

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.
