Pros & Cons

Pros

✓ DDR5-6000 CL30-40-40-96 at 1.35V, tight primaries for the speed grade
✓ One BIOS toggle: the Intel XMP 3.0 profile applies the full 6000MT/s rating
✓ Boots at JEDEC SPD default, so the PC posts before any overclocking
✓ Validated on Intel Z890, Z790, Z690, B860 and B760 boards per G.SKILL's QVL

Cons

✗ The rated 6000MT/s is not guaranteed, it depends on your motherboard and CPU
✗ Full speed needs XMP enabled manually; defaults run at slower JEDEC SPD
✗ No AMD EXPO profile listed, so AM5 users get JEDEC speeds unless tuned by hand
✗ Non-ECC modules, so not an option where error correction is required

Manufacturer description

The G.SKILL Ripjaws S5 DDR5 memory kit pairs two 16GB U-DIMMs for 32GB total, rated up to DDR5-6000 with CL30-40-40-96 timings at 1.35V, the latency-per-megatransfer mix most gaming builders target on current Intel platforms. Out of the box the kit boots at its JEDEC default SPD speed on compatible hardware, so your system posts before you touch a single BIOS menu. Loading the included Intel XMP 3.0 profile unlocks the full 6000MT/s rating; G.SKILL is explicit that enabling XMP is an act of overclocking and that the speed you actually reach depends on your motherboard and CPU. The company…

SpecPicks Verdict

SpecPicks scored G.SKILL Ripjaws S5 Series DDR5 RAM (Intel XMP 3.0) 32GB (2x16GB) Up… using a rating × review-volume × price-fit model applied to published specs and reviews across the memory (ram) category. G.SKILL's memory (ram) lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for memory (ram) of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this kit run at 6000MT/s out of the box?

No. With default BIOS settings it boots at the JEDEC default SPD speed. Enable the Intel XMP 3.0 profile in BIOS to reach the rated DDR5-6000 CL30-40-40-96 at 1.35V. G.SKILL notes that enabling XMP is overclocking and the result depends on your motherboard and CPU.

Which motherboards is the F5-6000J3040F16GA2-RS5K kit validated for?

G.SKILL lists Intel Z890, Z790, Z690, B860 and B760 platforms for this kit. Check the G.SKILL memory QVL or the RAM Configurator tool on G.SKILL's website to confirm your exact board and CPU combination before buying.

Can I buy a second kit later to reach 64GB?

G.SKILL advises against it. These modules are sold as a matched 2x16GB set designed to run together, and mixing kits can cause instability or system failure. If you expect to need 64GB, buy a single 64GB kit instead of doubling up on this one.

Does it work with AMD Ryzen AM5 boards?

The only overclock profile on this kit is Intel XMP 3.0, and the platforms G.SKILL validates are Intel Z890, Z790, Z690, B860 and B760. There is no EXPO profile listed, so on AM5 you would be running JEDEC default speeds or tuning manually. Check your board's QVL first.

Is this ECC memory, and what is in the box?

It is non-ECC. You get two 16GB DDR5 U-DIMMs, 288-pin, 32GB total, in a matte black finish, model F5-6000J3040F16GA2-RS5K. Check the product listing for current warranty terms.
