128GB DDR5 4800 ECC RDIMM Server Memory
This 128GB DDR5 4800 ECC RDIMM module is built for servers and workstations that require registered, error-correcting memory. It replaces Samsung M321RAGA0B20-CWK and M321RAGA0B20-CWKZJ parts in compatible platforms.
DDR5 4800 registered DIMM limits
The DDR5 4800 standard at PC5-38400 speed requires a motherboard and CPU that support registered ECC DIMMs at 1.10V. Systems limited to lower DDR5 speeds or unbuffered memory cannot use this module.
128GB 4Rx4 3DS capacity
The single-module 128GB density uses 4Rx4 3DS/TSV organisation with Samsung chipset. Platforms that do not support this rank structure or maximum capacity per slot will not recognise the full memory.

이 상품에 대한 질문
Should I choose the 128GB single module or add multiple modules for my server?
This is a single 128GB module. Add more identical modules to reach your platform's maximum capacity and populate channels evenly for best bandwidth.
What does the 4800MHz speed deliver in a real server workload?
DDR5 4800 (PC5-38400) provides high throughput for virtualization, databases and compute tasks, with ECC correcting single-bit errors to maintain data integrity.
How does the 288-pin DDR5 RDIMM interface limit performance?
The registered 288-pin DDR5 DIMM runs at 1.1V with CL40 latency; the memory controller and CPU determine the final operating speed and maximum supported capacity.
