Product & procurement FAQ
What is the difference between UDIMM, SODIMM and RDIMM?
UDIMM is commonly used in desktops, SODIMM in notebooks and compact systems, and registered ECC RDIMM in compatible enterprise servers. Verify the exact motherboard and processor requirements.
Are DDR4 and DDR5 interchangeable?
No. The generation, pin arrangement, voltage and platform support must match. Send the existing module information and system model before ordering.
Does DDR5 consumer memory provide server-level ECC?
DDR5 on-die error correction is distinct from system-level ECC. Consumer UDIMM and SODIMM configurations in this catalogue must not be treated as ECC RDIMM substitutes.
Which server memory should I choose?
Match the exact server model, processor generation, DIMM type, capacity, rank and supported data rate. DDR4 and DDR5 are not interchangeable. Send your server configuration and existing part number for a compatibility review.
Can I request a mixed-part-number quote?
Yes. Add several modules to your quote basket or paste your bill of materials. Include target quantities, destination and required delivery date so we can confirm availability and commercial terms.
Do you offer OEM and ODM memory modules?
StarwayDram offers label, packaging and specification customization, with engineering review, samples, validation and volume production. Minimum order quantities and sample lead times depend on the project.
How are server memory modules tested?
Our manufacturing process includes incoming inspection, SMT assembly and AOI checks. Functional, stress, compatibility and environmental testing are defined for the selected module and order. Ask our team for the applicable test scope and records.
