We put the G.Skill Trident Z5 RGB DDR5-7200 48GB kit through the paces in our test suite and found it to be a strong contender for our list of best RAM. You've probably heard the terms "non-standard" or "non-binary" associated with some of the new DDR5 memory kits. This signifies that the kit's capacity doesn't conform to the standard capacities that we've been accustomed to. Memory integrated circuit (IC) capacity has typically come in a power of two formats because DRAM vendors previously used 8Gb (1GB), 16Gb (2GB), and 32Gb (4GB) chips for their DDR4 memory kits. However, the introduction of DDR5 memory has changed the game. DDR5 brought the debut of non-power-of-two ICs, commonly called non-binary, in the form of 24Gb (3GB) dies.
Chipmakers have made significant progress in manufacturing processes to increase IC capacity. The latest 24Gb dies slot between the existing 16Gb and 32Gb ICs, allowing vendors to offer a density that was previously unavailable on the market. As a result, we're now seeing 24GB memory modules, the halfway point between 16GB and 32GB, and 48GB memory modules with 50% more density than 32GB DIMMs. Non-binary memory has opened the doors for the best RAM to arrive in 2 x 24GB, 2 x 48GB, 4 x 24GB, and 4 x 48GB configurations.
The Trident Z5 RGB design will look very familiar to avid G.Skill fans. It still retains the fin-inspired aluminum heat spreader. This memory kit, in particular, comes with a matte black theme. The brand typically offers the Trident Z5 RGB in a metallic silver option, but it depends on the SKU. A brushed aluminum strip with a slightly reflective finish and the Trident Z5 RGB logo decorates the middle of the memory modules. As we've seen with previous Trident Z5 memory kits, the memory modules retain a height of 42mm (1.65 inches) and, in most cases, are short enough to fit underneath CPU air coolers.
RGB lighting is a standard nowadays on high-performance gaming memory, and the Trident Z5 RGB has plenty of it. The RGB light bar on top of the memory modules accentuates the aggressive design. The Trident Z Lighting Control software is included for customizing the illumination, or you can use your motherboard software, including Asus Aura Sync, Gigabyte RGB Fusion 2.0, MSI Mystic Light Sync, and ASRock Polychrome.
Featuring a single-rank design, each memory module is 24GB in capacity. There are eight SK hynix H5CGD8MHBDX021 ICs, each with 3GB of density, under the Trident Z5 RGB's heat spreader. G.Skill doesn't have a preferred power management ICs (PMICs) provider for the brand's DDR5 products. For this particular memory kit, the company procured the APW8502C-AZ14Y from ANPEC.
Like other high-speed memory kits, the Trident Z5 RGB runs at DDR5-5600 and 46-45-45-90 timings when you first take it for a ride. It's rare for G.Skill to implement more than an XMP 3.0 profile on its memory. The only profile on the Trident Z5 RGB corresponds to the advertised specifications, which is DDR5-7200 with 36-46-46-115 timings at 1.35V. See our PC Memory 101 feature and How to Shop for RAM story for more timings and frequency considerations.

The Intel system runs the Core i9-13900K on the MSI MEG Z690 Unify-X with the 7D28vAA firmware. In contrast, the AMD system pairs the Ryzen 7 7700X with the MSI MPG X670E Carbon WiFi changed to the 7D70v176 firmware. The Corsair CUE H100i Elite LCD liquid cooler keeps our Raptor Lake and Zen 4 processor operating temperatures under check.
The MSI GeForce RTX 4080 16GB Gaming X Trio tackles the more graphics-intensive workloads, ensuring that there isn't a graphics bottleneck in our gaming RAM benchmarks. The Windows 11 installation, benchmarking software, and games reside on Crucial's MX500 SSDs. Meanwhile, the Corsair RM1000x Shift ATX 3.0 power supply provides our systems with clean and abundant power, directly feeding the GeForce RTX 4080 with a native 16-pin (12VHPWR) power cable. Lastly, the Streacom BC1 open-air test bench is vital to organizing our hardware.

The memory kit checks in at DDR5-7200 with decent timings; therefore, it's pretty fast coming out of the box. The extra capacity gave it an edge over the 32GB (2x16GB) memory in workloads the benefit of higher capacity. For example, the Trident Z5 RGB DDR5-7200 outperformed the second-fastest memory kit by 9.6% in Adobe Premiere.
It would be a more fair comparison to pitch G.Skill's memory kit against competitors with similar density; however, it's the first and only non-binary memory kit in the lab, so this imperfect comparison will have to do for now.
We didn't benchmark this kit on our Ryzen 7000 test platform because it can't reach the peak speeds needed to unlock the best performance from this kit, and it wouldn't make sense to purchase this kit to use it at the standard DDR5-5600 transfer rate.
The current state of the AGESA code and silicon limitations put AMD's Ryzen 7000 processors at a disadvantage regarding memory support. However, the good samples with a powerful IMC (integrated memory controller) typically support DDR5-6400 to DDR5-6600 memory.
For our particular Ryzen 7 7700X, DDR5-6400 is the ceiling, so DDR5-7200 is beyond the bounds of possibility.
Overclocking and Latency Tuning
The Trident Z5 RGB DDR5-7200 C36 exhibited similar overclocking margins as the Trident Z5 RGB DDR5-7200 C34, so the higher density didn't impact overclocking potential. The memory modules achieved DDR5-7600 with timings and DRAM voltage configured to 36-46-46-115 and 1.45V, respectively.

The memory kit fell a bit behind when it came to optimization. With the DDR5-7200 C34 variant, we got the timings down to 34-41-41-81 at 1.45V, whereas the DDR5-7200 C36 was at hairline instability with 34-42-42-84. Although the ICs are from the same brand, the memory kits use different models, hence the minor variation is normal.
The specifications for the Trident Z5 RGB DDR5-7200 C36 are enough to tell you that it's a high-performance memory kit by nature. G.Skill binned the memory modules at a high frequency with good timings. Unfortunately, this action practically dismissed AMD's Zen 4 platform, which struggles with memory kits above DDR5-6600.
The Trident Z5 RGB DDR5-7200 C36's timings aren't the tightest in the category but are above standard. Then, there's the added value of using SK hynix ICs that enables the memory kit to hit even greater frequencies if you're into overclocking. However, the Trident Z5 RGB DDR5-7200 C36's primary strength is its capacity.
The Trident Z5 RGB DDR5-7200 C36 48GB (2x24GB) is available for $239.99, which works out to $5 per GB. The Trident Z5 RGB DDR5-7200 C34 32GB (2x16GB) retails for $165.99, around $5.19 per GB. Therefore, the 48GB memory kit offers slightly better value for your money, assuming you're on the market for that capacity.
No vendor has launched a DDR5-7200 64GB (2x32GB) memory kit thus far, so a pricing comparison is currently unavailable. There aren't many DDR5-7200 48GB memory kits on the market, so G.Skill has the early bird advantage. Besides G.Skill, TeamGroup has a competing memory kit with better timings, but it hasn't hit the retail market yet.
