Ripjaws V 32 GB DDR4 Kit

The G.SKILL Ripjaws V F4-4000C18D-32GVK provides 32 GB of DDR4 memory in a matched dual-channel kit of two 16 GB modules. It runs at 4000 MT/s with a CAS latency of 18 and timings of 18-22-22-42 at 1.40 V. The kit targets enthusiasts building or upgrading Intel Z590, Z490 or AMD X570 platforms for gaming and content creation.

288-Pin Unbuffered DIMMs for Dual Channel

Each module uses the standard 288-pin DDR4 form factor and is unbuffered and non-ECC. The kit is validated for Intel XMP 2.0, so the rated speed and timings load with a single BIOS setting. The 42 mm module height clears most oversized CPU coolers. Do not mix this kit with other memory kits; it is sold as a matched pair for reliable dual-channel operation.

Aluminium Heatspreader at 1.40 V

Black aluminium heatspreaders pull heat away from the DRAM during sustained loads at 1.40 V. The low-profile design keeps airflow unrestricted around the CPU cooler area. With no active lighting or moving parts, the modules add no audible noise to the system. Power draw scales with the 1.40 V operating voltage and the 4000 MT/s data rate under typical workloads.

Questions about this item

Will the 1.40V voltage limit headroom for long gaming sessions?

The kit runs at 1.40V with CL18 18-22-22-42 timings; sustained loads stay within the rated voltage so the aluminium heatspreader handles the heat without extra cooling.

How loud or hot do the modules get after hours at 4000 MT/s?

No fans are present — the 42 mm tall black aluminium spreader dissipates heat silently, so noise stays at zero and temperatures remain acceptable for typical desktop airflow.

Which motherboard and CPU combination do I need to run this DDR4 4000 kit at rated speed?

Enable Intel XMP 2.0 on a Z590 or Z490 board with a compatible Intel CPU, or use an AMD X570 platform that supports the 4000 MT/s data rate.
