Compatible Systems
HPE Server Platforms: Fully compatible with HPE ProLiant Gen10 and Gen10 Plus servers supporting 2666MHz DDR4 LRDIMMs, including ProLiant DL360 Gen10, DL380 Gen10, ML350 Gen10, BL460c Gen10, and Synergy 480/660 Gen10 compute modules.
General Server Compatibility: Compatible with enterprise server motherboards and systems supporting DDR4 288-pin LRDIMMs using 1st and 2nd Gen Intel Xeon Scalable or AMD EPYC processors.
Compatibility Gotchas: LRDIMMs (Load-Reduced DIMMs) CANNOT be mixed with RDIMMs (Registered DIMMs) or UDIMMs (Unbuffered DIMMs) in the same system or channel. Standard desktop/consumer motherboards (e.g., Intel LGA 1151/1200/1700 or AMD AM4/AM5) do NOT support LRDIMM server memory. Always verify your server board population rules and CPU memory controller support prior to installation.
Ideal For
- Enterprise RAM upgrades and capacity expansions in HPE ProLiant Gen10 server infrastructures.
- High-density homelab host nodes requiring large memory footprints (Proxmox VE, VMware ESXi, TrueNAS CORE/SCALE, Microsoft Hyper-V).
- RAM-intensive workloads including database servers, heavy containerization clusters (Kubernetes/Docker), and virtualized lab environments.
