System-Specific 64GB DDR4 Kit
This 64GB kit contains four 16GB unbuffered DIMMs built for the Supermicro SuperWorkstation 5039C-T and X11SCA-series motherboards. It is intended for professionals who need guaranteed compatibility without manual configuration.
2666MHz CL19 Capacity and Limits
The modules run at 2666MHz with CL19 timings and 1.2V, filling all four sockets to reach the platform's 128GB maximum. Performance scales to the slowest installed module or CPU capability, so mixing with slower sticks reduces speed.
288-Pin Unbuffered Build
Each stick uses a 288-pin DDR4 PCB without a heat spreader, relying on chassis airflow for cooling. The non-ECC, 2Rx8 layout suits workstation workloads that do not require error correction, and matched-pair installation is recommended for stability.

商品問答
Will the 2666MHz CL19 modules down-clock to match older DDR4 sticks I keep in the Supermicro X11SCA motherboard?
Yes, all installed memory runs at the speed of the slowest module or the CPU limit, so older DDR4 DIMMs will set the operating frequency.
How can I confirm the 64GB kit is running at 2666MHz with CL19 timings after installation?
Check the BIOS memory information or a tool such as CPU-Z; it should report 2666MHz, 19-19-19 timings and 1.2V across all four slots.
Does the package contain only the four 16GB DIMMs or are heat spreaders and cables included?
The box holds four 288-pin DDR4 DIMMs; no heat spreaders, cables or extra accessories are supplied.
