64GB DDR4 kit for ASUS workstation boards

This 64GB kit contains four 16GB unbuffered DIMMs built for ASUS and Asmobile motherboards including the P11C-I, P11C-M/4L and WS C246 PRO models. It targets system builders and IT teams who need a validated memory upgrade for these specific workstation platforms.

DDR4 2666 CL19 1.2V specification

Each module runs at DDR4 2666 (PC4 21300) with CAS latency 19 and 19-19-19 timings at 1.2V. The 2Rx8 rank organisation and non-ECC unbuffered design must match the motherboard memory controller requirements for the system to post and run stably.

Sustained load behaviour with four populated slots

Populating all four slots places the maximum electrical load on the memory controller, so the kit operates at the rated 2666MHz rather than any higher speed. The modules have no heat spreaders, so case airflow must be sufficient to keep temperatures in check during prolonged workloads.

商品問答

How does the 2666 MHz speed translate once the kit is installed in a real machine?

The four 16 GB modules run at DDR4 2666 with CL19 19-19-19 timing at 1.2 V, delivering PC4 21300 bandwidth across all four slots when the board and CPU support that frequency.

What does the 288-pin DDR4 interface cap in practice?

The 288-pin DDR4 DIMM form factor limits the kit to dual-channel boards with four slots; total capacity cannot exceed 64 GB and the system will run at the slowest installed module or CPU limit.

What physical clearance does the 288-pin DIMM kit need to fit the listed ASUS boards?

Each 16 GB stick is a standard-height 288-pin unbuffered DIMM without a heat spreader, so it fits the P11C-I, P11C-M/4L and WS C246 PRO slots without extra clearance.
