G.Skill Ripjaws V 32GB (2x16GB) DDR4-3200 CL16 vs G.Skill Trident Z5 Neo RGB 64GB (2x32GB) DDR5-6000 CL30

The Ripjaws V is the budget pick because the cheapest way to add memory this year is often to stay on the platform you already own. A 32GB DDR4 kit costs well under half the price of the 32GB DDR5 kit in this guide, and for a Ryzen 5000 or a DDR4-board Intel build, DDR4-3200 at CL16 is the long-standing sweet spot.

The kit is model F4-3200C16D-32GVK: two 16GB sticks, timings of 16-18-18-38 at 1.35V, with an Intel XMP profile that AMD boards also read. It boots at the slower JEDEC default speed, so you need to switch XMP on in the BIOS once to get the rated 3200 MT/s. The heat spreader is a low 42mm profile with no lighting, which clears most large tower air coolers.

The catch is that DDR4 is a dead end for upgrades. DDR4 and DDR5 sticks are keyed differently and will not fit each other's slots, and every current AMD AM5 board uses DDR5 only. This kit is for an existing DDR4 system only. Our tracked price since Aug 9 has run from $209.89 to $239.99.

The 64GB Trident Z5 Neo is the premium pick for one reason: some workloads need the capacity, and two 32GB sticks are the right way to get it on AM5. Filling all four slots with 16GB sticks usually forces lower memory speeds on DDR5 platforms, while a two-stick 64GB kit keeps the full 6000 MT/s rating.

The kit is model F5-6000J3040G32GX2-TZ5NR. It keeps the CL30 primary latency of the 32GB version, with slightly looser secondary timings of 30-40-40-96 and 1.40V instead of 1.35V. That is normal for higher-density sticks and still runs from a single AMD EXPO profile. G.Skill lists validation for X870, X670, B850, B840 and B650 boards.

Who it is not for matters more than usual this year. Games rarely use more than 32GB, so a gaming PC gains nothing from this kit except a much larger bill. At $1,119.99 on Oct 19, it costs about $480 more than the 32GB kit. Buy it if your editor, compiler or virtual machines already push past 32GB and start swapping to disk. Our tracked price since June 26 has run from $924.99 to $1,149.99.
