System-specific DDR4 kit

This 32GB kit contains four 8GB DDR4 DIMMs rated at 2400MHz with CL17 timing and 1.2V operation. It is built for MSI X299 Raider, SLI Plus, Tomahawk Arctic and XPOWER Gaming AC motherboards. The unbuffered non-ECC modules use 2Rx8 organisation and 288-pin layout.

Motherboard and CPU alignment

Verify that your board is one of the four listed X299 models before ordering. Six-core and above Core X processors (78xx and 79xx) provide eight DDR4 slots supporting up to 128GB. Four-core i7-7740X or i5-7640X CPUs provide four slots supporting up to 64GB. The kit fills four slots exactly.

Sustained-load behaviour

CL17 latency and 1.2V voltage deliver stable throughput during extended workloads on the X299 platform. Major-brand chipsets and 2Rx8 rank structure maintain consistent timing without heat spreaders. Lifetime exchange or repair coverage from Computer Memory Solutions applies to manufacturing defects.

Questions about this item

Does the kit include four 8 GB DDR4 modules or do I need to buy extra sticks?

The package contains four 8 GB DDR4 DIMMs giving 32 GB total, so no additional modules are required.

How do I choose between the 2400 MHz CL17 kit and a faster or higher-capacity option?

This 32 GB kit runs at 2400 MHz with CL17 timing at 1.2 V; select it when your MSI X299 board and CPU combination supports that speed and you need four ranks of 2Rx8 unbuffered memory.

What does the 2400 MHz rating mean once the memory is installed in an MSI X299 system?

The modules will operate at DDR4 2400 (PC4 19200) with 17-17-17 latency, delivering the rated throughput provided the processor and motherboard firmware enable that frequency.
