Frequently Asked Questions

How do I identify a Samsung server memory part number?

Samsung server memory part numbers start with M followed by 3 digits indicating series (M393 = DDR4 RDIMM, M391 = DDR4 UDIMM, M386 = DDR4 LRDIMM, M474 = DDR5 SODIMM). The 4-character middle code encodes capacity, rank and speed. Email us your existing module label and we'll match the exact part.

Are Samsung DDR4 RDIMM and DDR5 RDIMM interchangeable?

No — DDR4 and DDR5 are physically and electrically incompatible (different pin counts, different voltage, different command set). Verify your motherboard's memory technology in the QVL before purchasing.

Can you ship Samsung memory in bulk for HCI cluster builds?

Yes — we routinely stage 200-1000 unit Samsung memory orders for vSAN / Nutanix / VMware Cloud Foundation cluster builds. 5-business-day lead time for bulk staging, endurance-matched lots on request, palletised delivery.
