Ripjaws S5 64 GB DDR5 Kit

The G.SKILL Ripjaws S5 Series delivers 64 GB of DDR5 memory in a dual-channel kit of two 32 GB modules. It runs at 6000 MT/s with CL36 timings and a 1.35 V operating voltage. The kit is built for DIY builders and PC enthusiasts who want high-speed DDR5 performance on modern AMD and Intel platforms.

Low-Profile 33 mm Modules for Tight Builds

Each module measures just 33 mm tall, leaving clearance for large CPU coolers and compact cases. The 288-pin DDR5 DIMMs install in standard desktop slots and support both Intel XMP 3.0 and AMD EXPO profiles for automatic overclocking. At default BIOS settings the memory boots at SPD speed, so no manual tuning is required to get started.

Aluminium Heatspreader Handles Thermals

A matte black aluminium heatspreader draws heat away from the hand-screened ICs during sustained workloads. The low voltage of 1.35 V keeps power draw modest while the tight 36-36-36-96 timings maintain efficiency. No onboard lighting means the kit runs silently and stays cool in everyday gaming and content-creation use.

Questions about this item

Will the 1.35 V operating voltage limit sustained performance?

The kit is rated for 1.35 V at DDR5 6000 CL36, so that voltage is the validated operating point rather than a throttle ceiling.

How hot or noisy do the 33 mm aluminium heatspreaders get during all-day loads?

The 33 mm low-profile heatspreaders are passive aluminium with no fans, so they add no noise and rely on case airflow to keep temperatures in check.

Which motherboard feature must already be present to run this kit at 6000 MT/s?

Your motherboard BIOS must support Intel XMP 3.0 or AMD EXPO to load the 6000 MT/s profile automatically.
