DDR5 ECC RDIMM
Registered ECC modules for compatible enterprise server and data-center platforms. Compare capacity, speed, rank, DRAM width and exact part number.
View DDR5 RDIMM ↗DDR5 ECC RDIMM & SERVER RAM
Server Memory Supplier for DDR5 ECC RDIMM and Registered Memory
Compare DDR5 and DDR4 ECC registered memory by module type, speed, capacity and platform requirement. YIHMA helps B2B buyers source enterprise server RAM by specification, server model or exact part number.
ECC RDIMM
01 / PRODUCT FAMILIES
Choose the memory family before comparing part numbers.
Module type is a compatibility decision, not simply a performance preference. Confirm the server or motherboard documentation before ordering.
DDR5 ECC UDIMM & ECC SODIMM
Unbuffered ECC formats for compatible entry servers, workstations and compact systems. These are not interchangeable with RDIMMs.
View DDR5 ECC memory ↗DDR4 ECC RDIMM
Registered ECC memory for established server platforms, maintenance requirements and capacity upgrades where DDR4 remains specified.
View DDR4 RDIMM ↗Exact Part-Number Sourcing
For BOMs, repeat orders and replacement requirements where the manufacturer part number and organization must remain controlled.
Send your BOM ↗02 / SPECIFICATION CHECK
Eight fields that define a useful server memory inquiry.
A complete RFQ reduces the risk of receiving a quote for the right generation but the wrong module organization.
DDR generation
DDR5 and DDR4 are physically and electrically different. Start with the platform-supported generation.
Module type
State RDIMM, LRDIMM, MRDIMM, ECC UDIMM or ECC SODIMM exactly as supported by the platform.
Module capacity
Provide capacity per DIMM and target total system capacity, not only the aggregate number.
Transfer rate
Specify the required data rate such as 5600MT/s, 6400MT/s or 3200MT/s and the CPU/platform involved.
Rank and organization
Include 1R/2R/4R, x4/x8 organization and component density when the BOM or platform requires it.
Voltage and form factor
Confirm voltage, pin count and full-size DIMM or small-outline form factor.
Manufacturer part number
Use the complete part number, including suffixes. Similar-looking codes can describe different builds.
Quantity and destination
Add quantity, delivery country, target date and required packaging or documentation.
03 / WORKLOADS
Match memory capacity and bandwidth to the deployment objective.
The final memory population plan depends on the server platform, CPU memory channels and the workload. Use these scenarios to frame the inquiry—not as a substitute for platform validation.
Virtualization & Private Cloud
Plan capacity per host, VM density, channel population and expansion headroom for compatible enterprise servers.
Discuss a host upgrade ↗AI, Analytics & HPC
Memory-intensive compute can be constrained by bandwidth, capacity or both. Share the server platform and target workload when requesting options.
Review a requirement ↗Database & In-Memory Workloads
State the working-set size, redundancy requirement and current DIMM population so the upgrade objective is clear.
Send a configuration ↗Maintenance & Lifecycle Replacement
Use exact part numbers and current module labels when replacing failed DIMMs or maintaining a standardized fleet.
Check a replacement ↗04 / RFQ CHECKLIST
Send one complete requirement for a faster quotation review.
Copy the checklist below into your email or WhatsApp message. Fields you do not know can be marked for confirmation.
System information
Server manufacturer and model, motherboard model if applicable, CPU model, current memory part number and current DIMM population.
Memory requirement
DDR generation, module type, capacity per module, speed, rank, x4/x8 organization and preferred manufacturer or exact part number.
Commercial requirement
Quantity, delivery country, target date, packaging expectation, Incoterm if known and any required inspection or documentation.
Confirmation before order
Confirm quoted model, condition, quantity, lead time, warranty/return terms, payment and shipping terms in writing.
05 / BUYER FAQ
Compatibility questions to resolve before purchase.
Are RDIMM and ECC UDIMM interchangeable?+
No. Registered and unbuffered modules use different electrical architectures. Use only the DIMM type supported by the server, CPU and motherboard.
Can RDIMM and LRDIMM be mixed in one server?+
Usually no. Treat them as different module types and follow the server manufacturer's population rules.
Can DDR5 memory be installed in a DDR4 server?+
No. DDR generations have different physical keying and electrical specifications.
Can different speeds be mixed?+
A platform may run mixed-speed modules at a common supported rate, but population rules vary. Confirm the server manual and CPU support before ordering.
Why do rank and x4/x8 organization matter?+
Rank and DRAM width affect module organization, platform support and population limits. Include them when matching an existing configuration or controlled BOM.
What is the safest way to request a replacement DIMM?+
Send clear photographs of both module labels, the complete manufacturer part number, server model, CPU and current memory population.
Does a higher advertised speed always improve the server?+
No. The effective speed is limited by the CPU, platform, DIMM population and firmware support.
Can YIHMA confirm final compatibility?+
YIHMA can organize a preliminary requirement review from the information provided. Final compatibility should be checked against the server or motherboard manufacturer's documentation.
Which brands and capacities are currently available?+
Availability changes by exact part number, quantity and timing. Request a current quotation instead of relying on a static stock claim.
What should be confirmed before payment?+
Confirm the complete quoted model, quantity, product condition, lead time, warranty/return terms, payment details and shipping terms in writing.
Send the part number, server model or complete BOM.
Include quantity, destination and target date. Jane will organize the open confirmation points before quotation.
