64GB LRDIMM for dense server configs
This SK hynix module delivers 64GB of DDR4 2666 memory in a 288-pin load-reduced form factor. It targets administrators who need maximum capacity per channel without hitting rank limits. The 4Rx4 organisation and ECC support make it suited to virtualisation hosts and in-memory databases. It is not for standard desktop boards that accept only unbuffered UDIMMs.
Thermals and power at rated speed
Operating at 1.20V, the module runs within the standard DDR4 voltage envelope and carries no heat spreader. Load-reduced buffering reduces electrical load on the memory controller, helping keep system power draw lower than an equivalent population of standard RDIMMs. Acoustic impact is negligible because the DIMM itself has no moving parts.
Sustained load behaviour in multi-DIMM arrays
The load-reduced architecture lets each channel accept more ranks than a conventional RDIMM, so bandwidth scales further when all slots are populated. Under continuous heavy traffic the module maintains its CL19 timing at 2666 MT/s without the rank bottlenecks that throttle standard registered DIMMs. It is not for workloads that demand 3200 MT/s speeds or densities beyond 64GB per module.

この商品に関する質問
How do I install this 288-pin DDR4 LRDIMM, and which step do people often miss?
Align the notch with the slot key, press firmly until both retention clips click, and confirm the motherboard supports Load Reduced DIMMs — standard RDIMM-only boards will not recognise the module.
What maintenance or replacement will this 64 GB 4Rx4 module need later?
No scheduled maintenance is required; if a DIMM fails, replace it with another DDR4 2666 CL19 1.20 V LRDIMM of matching rank and capacity to keep ECC and channel balance intact.
What limit appears first when this LRDIMM runs sustained workloads?
The DDR4 2666 (PC4 21300) data rate and CL19 latency set the bandwidth ceiling, while the 1.20 V supply and quad-rank density define the thermal envelope before throttling.
