DIMM Server Memory
DIMM parts. Form factor decides whether it seats in the bay or the slot at all, before any other specification matters.
We list 13 parts here from Micron, SK hynix and Samsung, from $55 to $1,495 per unit. 9 of the 13 are in stock; the rest are backorder or special order and we will confirm lead time with your quote.
Pricing shown is indicative and per unit — tiered pricing applies at quantity. If the exact part number you need is not on this page, send it to us anyway: we source well beyond the published catalogue, and quotes come back within 48 business hours. Purchase orders are accepted from qualified businesses, government and defence agencies, and educational institutions.
