G.Skill Trident Z5 RGB 32GB DDR5-8000 CL38
Among the fastest retail DDR5 kits when it launched, but it is an Intel-only XMP kit that G.Skill validated on a single overclocking motherboard, and Tom's Hardware expected it to need manual tuning unless the processor has a strong memory controller.

About this product
This page covers the G.Skill Trident Z5 RGB F5-8000J3848H16GX2-TZ5RK in matte black, a 32GB DDR5 desktop memory kit made of two 16GB sticks with an RGB light bar. It boots at 4800 MT/s and is rated for 8000 MT/s at CL38-48-48-128 and 1.45V once you enable its Intel XMP 3.0 profile in the BIOS. A metallic silver version, F5-8000J3848H16GX2-TZ5RS, has the same speed, timings and voltage.
G.Skill designed it for compatible Intel platforms and validated it at launch on an ASUS ROG Maximus Z790 Apex with a Core i9-13900K. It suits an enthusiast with a strong CPU memory controller and a motherboard built for fast memory. G.Skill notes that reaching the rated speed depends on the motherboard and CPU.
We found no professional hands-on review of this kit. The closest guides are one Tweakers owner review of the silver TZ5RS version and a SkatterBencher tuning article that ran this exact black kit at DDR5-8000 on an AMD motherboard.

- ✗ Needs a capable processor and motherboard, and may not reach its rated speed without manual tuning

Frequently asked questions
It ranks #11 of 15 on our RAM tier list, in D tier. That placement rests on one cited source.
A strong pairing. G.Skill validated the kit on an ASUS ROG Maximus Z790 Apex with a Core i9-13900K, and at launch Tom's Hardware reported that as the only validated board. One Tweakers owner reports the XMP profile working flawlessly on an MSI Pro B860M-A with an Intel Core Ultra 200 processor. Check your board's memory support list before buying.
G.Skill designs this kit for Intel platforms and gives it only an Intel XMP 3.0 profile. SkatterBencher did run this exact part number at DDR5-8000 on an ASUS ROG Crosshair X870E Hero, with the memory controller at half the memory clock and some sub-timings adjusted by hand, so it is possible but not what the kit is built for.
Yes. Out of the box the kit boots at 4800 MT/s. You enable the XMP profile in the BIOS to reach 8000 MT/s, and G.Skill notes that this counts as overclocking and that the result depends on your motherboard and CPU.
G.Skill lists the Trident Z5 RGB at 44mm (1.73in). The Tweakers owner notes the height is not compatible with every cooler, so compare 44mm with the memory clearance your cooler's maker lists.
G.Skill advises against it. Its spec page says memory kits are sold as matched sets and that mixing kits will result in stability issues or system failure. If you need 64GB, buy it as one kit.
