32GB DDR5 4800MHz Server Module
This 32GB DDR5 module operates at 4800MHz with CL40 latency and 1.20V. It is an unbuffered, dual-rank 288-pin DIMM designed for server platforms that support DDR5-4800 memory. The single-module configuration provides a straightforward capacity upgrade for compatible systems.
Simple DIMM Installation
Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage, and verify seating. The unbuffered design means no register timing complications arise during POST. The most common issue is a motherboard that does not officially support DDR5-4800 unbuffered modules, which can prevent boot or limit speed.
DDR5-4800 Platform Limits
The module runs at the JEDEC base data rate of 4800MT/s with PC5-38400 bandwidth. Real-world throughput depends on the memory controller, channel population and BIOS revision. Dual-rank organisation can improve bandwidth utilisation on supported platforms, but maximum stable frequency and rank-per-channel limits are dictated by the specific server board and processor combination.

商品問答
How can I verify the module is running at 4800 MHz with CL40 after installation?
Enter the system BIOS or use a hardware-monitoring utility; the SPD should report DDR5-4800, PC5-38400 speed and CL40 latency at 1.20 V.
What ships in the box and what must I source separately?
The package contains one 32 GB 288-pin unbuffered DDR5 DIMM; no cables, brackets or additional modules are included.
Which capacity version should I choose for a dual-channel server board?
This SKU is a single 32 GB dual-rank module; add a second identical module to populate both channels.
