Who it fits

Key specs explained for this RAM

Capacity: 64GB

This single module provides 64GB of total memory. You use this for large virtual machines or in-memory databases that need substantial space. It fits high-density server slots. Compare this to 32GB sticks if you need less capacity. Higher capacity reduces the need for multiple sticks on boards with limited slots.

Form Factor: 288-pin LRDIMM

This is a Load-Reduced DIMM with 288 pins. It uses buffering to lower electrical load on the memory bus. You need this for high-DIMM-count server boards. It is not compatible with standard desktop UDIMMs or RDIMMs. Check your server manual to confirm LRDIMM support before buying.

Memory Speed: 2933MHz

The module runs at 2933MHz, also known as PC4-23400. This speed matches the expectations of your server memory controller. It ensures the system posts correctly at full capacity. Match this speed with other installed sticks to avoid downclocking. Faster speeds may not be supported by your specific CPU platform.

CAS Latency: CL21

CL21 indicates the delay before data access begins. This latency is standard for LRDIMMs at this speed. Lower latency improves response times for database queries. Compare CL21 with CL19 or CL22 when evaluating performance. The buffering in LRDIMMs often results in slightly higher latency than standard RDIMMs.

Voltage: 1.2V

This module operates at 1.2V, the standard for DDR4. Lower voltage reduces power consumption and heat generation in your server. This helps maintain stability during 24/7 multi-socket workloads. Ensure your server power supply and motherboard support standard DDR4 voltage. Do not mix with older 1.5V DDR3 modules.

Physical Design And Build Details

According to the listing, this module measures 8 inches in length and 3 inches in width. The height is listed as 1 inch. These dimensions align with standard 288-pin DIMM slots found in server racks and workstations. The physical size ensures it fits into high-DIMM-count boards without interfering with adjacent slots or cooling solutions. You must verify that your server chassis has adequate clearance for this specific form factor.

The listing identifies the model as compatible with the Apple Mac Pro 2019 (MacPro 7,1). It also notes general compatibility with PCs and servers. This suggests the physical build adheres to industry standards for LRDIMM modules. The 288-pin configuration is critical for load-reduced buffering. This design lowers the electrical load on the memory bus. You benefit from this when running high-capacity workloads like virtualization or in-memory databases.

The listing does not specify the color of the heat spreader or the specific materials used in the PCB. It only confirms the 288-pin LRDIMM form factor. You should assume a standard black or green PCB unless otherwise stated. There are no visible controls, switches, or buttons on the module. The design is purely functional, focusing on electrical performance and physical compatibility. You rely on the manufacturer's lifetime warranty and US-based technical support for any issues related to build quality or fitment.

Setup And Daily Use Guide

Installing this module requires a server or workstation motherboard that explicitly supports LRDIMM technology. You cannot use this stick in standard desktop PCs or laptops because the 288-pin Load-Reduced DIMM form factor is distinct from RDIMM or UDIMM types. The listing notes that this is an exact-match upgrade for systems expecting 4Rx4 ECC memory at 1.2V and CL21 latency. Before you install, you must verify your platform’s QVL or BIOS settings. High-capacity servers often have strict population rules. If your board does not support LRDIMM at this specific capacity, the system will not post correctly. Once installed, the load-reduced buffering lowers the electrical load on the memory bus. This allows high-DIMM-count boards to reach maximum capacity per channel. In daily use, this setup supports virtualization, in-memory databases, and 24/7 multi-socket workloads. The ECC protection ensures data integrity during heavy processing tasks. You benefit from stable operation when running multiple large virtual machines simultaneously. The 2933MHz speed and 1.2V voltage are standard for DDR4 server environments. This configuration is ideal for enterprise environments requiring high density. It is not suitable for gaming or general consumer use. Always check your manual to confirm compatible memory types. The lifetime warranty and US-based support provide a safety net for enterprise deployments. You rely on the specifications to ensure compatibility. The precise rank and voltage matching helps the memory controller recognize the full 64GB capacity without errors. This reduces troubleshooting time during setup.

Before You Buy This Kit

You must confirm your server supports LRDIMM technology. This module is not for standard desktops or laptops. It fits only high-density server boards. Check your motherboard manual for LRDIMM compatibility. You also need to verify the maximum capacity per channel. This stick lowers electrical load on the memory bus. It helps high-DIMM-count boards reach maximum capacity. Ensure your BIOS supports 64GB modules. You may need multiple sticks for full channel utilization. Compare this single 64GB stick with other options. The listing shows configurations up to 768GB. Choose based on your workload needs. Virtualization and in-memory databases benefit from this density. Keep your server firmware updated. This ensures stable operation at 2933MHz. You should also verify ECC support in your system. This memory type requires specific server hardware. Do not assume compatibility with consumer platforms. Proper fitment prevents boot failures. Review your platform’s qualified vendor list. This step saves time and ensures correct operation.

Check before you buy

• Confirm your server supports LRDIMM form factor
• Check motherboard manual for 64GB module support
• Verify BIOS updates for stability
• Ensure ECC memory is enabled in settings
