64 GB Load-Reduced DDR4-2666 Server Memory
This 64 GB DDR4-2666 module uses a 288-pin Load Reduced DIMM form factor with ECC and a 4Rx4 rank configuration. It operates at 1.20 V with a CAS latency of 19. The design targets HP Synergy 480 G10 platforms and other servers that accept LRDIMMs to maximise installed memory capacity per channel.
Replaces standard RDIMMs when density limits are
Standard registered DIMMs restrict the number of modules per channel; this LRDIMM removes that ranking limitation so more DIMMs can be populated. The upgrade is worthwhile when virtualization, in-memory databases or HPC workloads demand total system memory beyond what RDIMM populations allow. It also delivers higher memory bandwidth and better energy efficiency than standard RDIMMs at the same 2666 MT/s data rate.
Installation requires matching memory type
The module must be installed in a server platform qualified for DDR4-2666 Load Reduced DIMMs; it cannot be mixed with ECC UDIMMs or standard RDIMMs in the same system. All existing UDIMMs must be removed before populating LRDIMMs. No heat spreader is fitted, so airflow across the module must be adequate. Verify the motherboard or server memory-qualified vendor list before purchase.

Otázky k tomuto produktu
Will this 288-pin DDR4 LRDIMM fit the HP Synergy 480 G10 memory slots?
The module uses the standard 288-pin DDR4 form factor required by the Synergy 480 G10, so it seats directly in the server’s DIMM sockets.
What is the correct installation sequence for these 4Rx4 Load Reduced modules?
Populate all slots of a channel before moving to the next channel; the common mistake is mixing ranks across channels which prevents the LRDIMM buffer from working.
When should I expect to replace these 64 GB DDR4-2666 CL19 sticks?
They are rated for continuous server operation at 1.20 V; plan replacement only if ECC correctable-error counts rise sharply or a DIMM fails POST.
