Capacity and kit size

This 64GB kit contains four 16GB DDR4 2400 CL17 modules in a 288-pin DIMM form factor. The memory runs at 1.2V with 17-17-17 timings and uses unbuffered, non-ECC chips. It is built for ASRock D1540D4I, Fatal1ty X299, X399 and X99 Professional series boards that accept this specification.

Builders who need this exact configuration

The kit suits users upgrading the listed ASRock platforms to 64GB using four matched sticks. Builders whose boards require ECC or registered DIMMs cannot use these modules. Systems limited to lower speeds or different pin counts should look at other memory. Buyers needing more than 128GB total capacity or eight populated sockets must choose a different solution.

Speed and latency target

The decisive specification is the DDR4 2400 CL17 rating (PC4-19200). If your motherboard and CPU combination requires this exact speed and latency pair, the kit will operate as intended; if the platform demands a different data rate or tighter timings, this memory will not meet that requirement.

Questions about this item

Will the 2400 MHz speed run at full rate on my Fatal1ty X299 board?

The kit is rated for DDR4 2400 (PC4 19200) and the listed ASRock X299 boards support that speed, so the modules will operate at 2400 MHz without manual tuning.

Does the 288-pin DDR4 interface limit total capacity on these motherboards?

Each board accepts 288-pin DDR4 DIMMs up to 128 GB across its eight sockets, so this 64 GB kit fits well within the maximum.

Will the four 16 GB sticks physically fit the DIMM slots on an ASRock D1540D4I?

The modules are standard 288-pin DDR4 DIMMs without heat spreaders, matching the slot layout of the D1540D4I and the Fatal1ty boards listed.
