Questions about this item

What does the DDR4 3000MHz CL15 rating mean for real-world throughput?

The kit runs at 3000MHz with CAS latency 15, delivering PC4-24000 bandwidth when the XMP 2.0 profile is enabled in the BIOS.

Will the 326.8 mil thick aluminum heat spreader clear my CPU cooler?

Each DIMM measures 326.8 mil thick, 1.7 inches wide and 5.3 inches long; verify your cooler clearance against those dimensions before ordering.

How do I get the rated 3000MHz speed on an Intel 100 or 200 series or X99 platform?

Enable the Intel XMP 2.0 profile in the motherboard BIOS; the modules default to a lower JEDEC speed until the profile is activated.
