G.Skill Ripjaws S5 Black 64GB (2x32GB) DDR5-6400 CL32

64GB (2×32GB)DDR5-6400 CL32Intel XMP 3.01.40V · Low-Profile Black

The G.Skill Ripjaws S5 F5-6400J3239G32GX2-RS5K is a 64GB (2×32GB) DDR5-6400 desktop memory kit that delivers high speed and capacity in a clean, low-profile design. It runs at 6400 MT/s with CL32 (32-39-39-102) timings at 1.40V using one-click Intel XMP 3.0, and ships as two matte-black UDIMMs without RGB. The part number F5-6400J3239G32GX2-RS5K identifies this exact black 64GB kit. Typically in stock with fast delivery across Cyprus.

Compatibility — check before buying:
This is a DDR5 UDIMM kit and works only in DDR5 motherboards — it is not compatible with DDR4 or DDR3 boards. The rated profile is Intel XMP 3.0; it is designed for Intel platforms and also fits AMD AM5 DDR5 boards, which can typically read the XMP profile. Confirm your board’s QVL supports 6400 and 64GB / 32GB modules, update the BIOS, and enable XMP. The low-profile heatspreader clears large tower air coolers easily.

Frequently Asked Questions

Does my board support DDR5-6400 and 32GB modules?
Check your motherboard’s QVL for 6400 and 32GB modules, update the BIOS, and enable XMP. Most current Intel boards handle 6400 well; on AMD AM5 the practical sweet spot is nearer 6000, so an EXPO kit may suit Ryzen better.
Is this an Intel or AMD kit?
Ripjaws S5 is G.Skill’s Intel XMP line, so the rated profile is XMP 3.0. It is DDR5 and physically fits AMD AM5 boards, which can typically read XMP.
Does it have RGB?
No. Ripjaws S5 is a low-profile, non-RGB kit for clean and small-form-factor builds. For RGB at this speed, see the Trident Z5 RGB.
Is this ECC or registered memory?
No. It is unbuffered, non-ECC desktop UDIMM memory. DDR5 chips include on-die ECC for internal integrity, but this is standard consumer memory, not registered (RDIMM) or module-level ECC.

Expert Insight

Singular Expert Insight
Ripjaws S5 is G.Skill’s clean low-profile Intel-XMP line — a no-RGB, value-oriented choice. At DDR5-6400 CL32 it delivers high speed and 64GB capacity, ideal for tidy or small-form-factor Intel builds. If you want RGB, the Trident Z5 RGB is the counterpart; for AMD EXPO, a Flare X5 6000 kit suits Ryzen. Browse our Memory / RAM category for other DDR5 kits.

Buyer’s Guide

Buy it if
You want fast 64GB DDR5-6400 CL32 in a clean low-profile design without RGB for an Intel build.
Skip it if
You have AM5 and prefer a 6000 EXPO kit, you want RGB, or can’t confirm 6400 / 32GB support.
Also consider
The Trident Z5 RGB 6400 for lighting, or a DDR5-6000 CL30 EXPO kit for AM5.
