64GB DDR4-3200 ECC Registered Module
This 64GB DDR4-3200 module delivers registered ECC memory for servers and workstations that require error correction and signal buffering. The dual-rank 2Rx4 organisation increases density within a single 288-pin DIMM slot. It is built for systems qualified for PC4-25600 operation.
DDR4-3200 Speed and Registered Buffer Limit
The module runs at 3200 MT/s with a CAS latency of 22 cycles. Registered buffering adds one clock cycle of address/command delay, which stabilises heavy loads but prevents use in platforms that accept only unbuffered DIMMs. Maximum throughput is bound by the DDR4-3200 interface.
64GB Capacity per DIMM Decides Fit
A single stick provides 64GB, so the total memory ceiling depends on how many registered DIMM slots the motherboard exposes. Boards limited to lower per-slot capacities or unbuffered memory cannot use this module. Verify the platform's qualified vendor list before purchase.

이 상품에 대한 질문
Should I choose the 64 GB dual-rank module or look for a single-rank alternative?
This module is a 64 GB dual-rank (2Rx4) DDR4-3200 registered DIMM; dual-rank can improve bandwidth on supported platforms but requires a motherboard that accepts registered ECC memory.
What does the DDR4-3200 CL22 rating mean for actual throughput in a server?
The module runs at 3200 MT/s with a CAS latency of 22 cycles, delivering up to 25 600 MB/s theoretical peak bandwidth when the platform operates at the rated speed.
Does the 288-pin registered DDR4 interface limit the maximum speed I can reach?
The 288-pin registered DDR4 form factor supports the rated DDR4-3200 speed; actual operating frequency is determined by the server's memory controller and BIOS configuration.
