Manufacturer description
The G.SKILL Ripjaws S5 64GB (2x32GB) DDR5 RAM kit (F5-6000J3238G32GX2-RS5K) gives an Intel desktop enough memory for heavy multitasking, large game installs, content creation and local workloads, without filling all four DIMM slots. Each 288-pin, non-ECC U-DIMM holds 32GB. The matched pair is rated for DDR5-6000 at CL32-38-38-96 and 1.40V through its Intel XMP 3.0 profile. Out of the box the kit boots at its JEDEC default SPD speed. To reach 6000MT/s, you enable XMP in the BIOS, and whether that speed stays stable depends on your motherboard and CPU. G.SKILL lists the kit for Intel Z890…

Frequently Asked Questions
Will the G.SKILL Ripjaws S5 64GB kit run at 6000MT/s right away?
No. It boots at its JEDEC default SPD speed at default BIOS settings. You must enable the Intel XMP 3.0 profile in the BIOS to reach DDR5-6000 CL32-38-38-96 at 1.40V, and stability depends on your motherboard and CPU.
Which motherboards is this DDR5 kit compatible with?
G.SKILL lists Intel Z890, Z790, Z690, B860 and B760 platforms. For your specific board, check the G.SKILL memory QVL or the RAM Configurator tool on the G.SKILL website.
Can I add a second Ripjaws S5 kit later to get 128GB?
G.SKILL advises against mixing memory kits. Each kit is matched to run as a set, and mixing kits can cause instability or system failure. If you need 128GB, buy a single kit of that capacity.
Is this RAM ECC or suitable for servers?
No. The F5-6000J3238G32GX2-RS5K uses non-ECC, 288-pin DDR5 U-DIMMs designed for desktop PCs and gaming systems, not ECC-dependent workstations or servers.
What does the kit include and what are its timings?
You get two 32GB DDR5 modules for 64GB total, rated DDR5-6000 at CL32-38-38-96 and 1.40V. The modules carry a JEDEC default profile plus an Intel XMP 3.0 overclock profile.
