At the time of writing, the largest dual memory kit offered by G.Skill is 128GB, available across four product lines. One of these is the Trident Z5 Neo RGB, available at DDR5-6000 with three latency choices. We review the CL34 model and find out just how well it performs. G.Skill's Trident Z5 Neo RGB memory has been designed for overclocking on AMD platforms with EXPO support. It is available with a choice of two coloured aluminium heat spreaders and features customisable RGB lighting. The 128GB DDR5-6000 kits are available in three latencies: CL32 (1.40V), CL34 (1.35V) and CL36 (1.25V). The CL32 has EXPO support only, while the other two support EXPO and Intel's XMP technology. The Trident Z5 Neo RGB kit we are reviewing here uses a pair of dual-ranked 64GB DIMMs (each using, according to the Thaiphoon Burner utility, 16 Samsung M-die ICs), EXPO rated at 6000MHz at 34-44-44-96 at 1.35V. G.Skill backs the modules with a lifetime warranty. Specification: Model Number: F5-6000J3444F64GX2-TZ5NR. Capacity: 128GB (64GB x 2). Rated Frequency: 6000MT/s. Rated Timings: 34-44-44-96. Voltage: 1.35V. Memory IC: Samsung M-die (K4RBH086VM-BCWM). Module Height: 42mm. XMP/EXPO: EXPO/XMP. The front of the box that the memory comes in has a cut-out near the top, allowing you to see part of one of the modules. Below this are two award logos, and below these are two illustrations of what the memory looks like. The bottom left of the box is home to the AMD EXPO sticker along with the Trident Z5 Neo RGB branding. The rear of the box has two more cutouts (top and bottom), which let you see the SKU sticker attached to the module. To the right of the bottom cut-out is the product sticker that displays the module density, configuration and what the EXPO profile provides. Below this product sticker is a line of logos representing the motherboard lighting software that the modules support: Asus Aura, ASRock Polychrome Sync, Gigabyte RGB Fusion and MSI Mystic Light Sync. The heat spreaders on the modules are made from aluminium finished in (in the case of the review sample) matte black with a black brushed-aluminium insert (a matte white finish is also available). The spreaders give the module a height of 42.8mm. The modules are a dual-rank design; under each heatsink, there are sixteen 4GB Samsung chips (K4RBH086VM-BCWM – M-die according to the Thaiphoon Burner utility) along with a Richtek RTQ5132GQWF power management IC (PMIC). The top of the module is home to the RGB defuser bar, which covers eight RGB zones which are controlled by either G.Skill's own controller software or by the motherboard RGB system. The memory runs at DDR5-5600 with timings of 46-45-45-90-135 (1.10V) natively with the single EXPO and Intel XMP profiles supporting DDR5-6000 with 34-44-44-96-140 timings at 1.35V. There are two ways of controlling the eight RGB zones sitting at the top of the module: G.Skill's own Trident Z lighting control software or via the motherboard lighting support. G.Skill's Trident Z lighting control software allows you to set up four profiles independently with their own custom light setup. The modules can be set up together or as individual units. The software has fourteen lighting effects and a wide colour palette to set up your desired effect. And as each module can be set up separately, you can come up with some pretty radical effects. There's also a Music Mode which can be customised, but once enabled, all the other profiles are disabled. However, in this mode, the modules will stay dark if there is no audio output. If you want to go down the other route with a motherboard utility, then Asus Aura Sync, Gigabyte RGB Fusion 2.0, MSI Mystic Light Sync, and ASRock Polychrome Sync are all supported. We will be testing the memory kit performance with an Intel Core i7-14700K CPU, MSI MPG Z790 Carbon WiFi motherboard and a GeForce RTX 4060 VENTUS 2X BLACK 8G OC graphics card. The processor is maintained at its stock frequency.

The CL34 timings don't seem to do the 128GB kit any favours, as it sits in last place in the result chart. Compute and Productivity Benchmarks 7-Zip In the 7-Zip Compressing benchmark, the 128GB kit of G.Skill's Trident Z5 Neo RGB DDR5-6000 C34 memory sits in fourth place in the results chart with a Compressing score of 182 GIPS, although there is not much to separate the top five in this table. Cinebench 2024 The 128GB kit's Cinebench 2024 CPU points score of 1924 sees it in the lower half of the results chart. Encoding Benchmark Handbrake In the Handbrake test, the 128GB kit is the fastest of G.Skill's Trident Z5 Neo RGB DDR5-6000 line-up we've tested to date. Office Productivity Benchmarks PCMark 10 Essentials Productivity Digital Content Creation In the PCMark 10 benchmark, the memory performs best in the Productivity set of traces, which sees it sitting in a mid-table position. In the Essentials and Digital Content Creation tests, it doesn't do as well, sitting near the bottom of the chart for both tests. Gaming (1080p) Benchmarks Total War Pharaoh - Battle Using the Ultra quality settings, the G.Skill's Trident Z5 Neo RGB DDR5-6000 C34 128GB kit sits in the bottom half of the Total War Pharaoh Battle benchmark, but truth be told, there isn't much separating any of the modules in this test. Easing off the quality settings down to the Low setting sees the memory still sitting in the bottom section of the chart, but up a position. But as with the Ultra settings, there's not much to choose between it and the modules placed above it. Final Fantasy XIV-Dawntrail Using the Ultra quality settings, the kit's score of 112.684 fps sees it in last spot on the results chart, but its 1% Low score is pretty strong. Although sitting in last spot, there's not much to choose between it and all the modules up to the third spot. Easing off the quality settings to the Low setting sees the memory move up a spot on the list. It's 1% Low score is the seventh best we've seen in this test. Cyberpunk 2077 When tested with the Cyberpunk game benchmark using the Ultra settings, the drive produced test results of 97.722fps (average) and 70.073fps (1% Low), which puts the memory in sixth place in the chart. Switching over to the low quality setting saw the module rise to the top of the table with a test result of 190.44 fps (average) and 124.711 fps (1% Low). We will be testing the memory kit performance with an AMD Ryzen 7 7700X CPU, MSI MPG X670E Carbon WiFi motherboard and a GeForce RTX 4060 VENTUS 2X BLACK 8G OC graphics card. The processor is maintained at its stock frequency.

Memory AIDA64 Using the AMD test platform, G.Skill's Trident Z5 Neo RGB DDR5-6000 C34 128GB kit produced a Memory Read score of 61,660MB/s, which places the kit into fourth place on the results chart, between G.Skill's Trident Z5 Royal 6400 C32 64GB kit and the Trident Z5 Neo RGB 6000 C28 96GB kit we tested recently. The C34 latency setting sees the modules propping up the results table. Compute and Productivity Benchmarks 7-Zip In the 7-Zip benchmark, the 128GB G.Skill Trident Z5 Neo RGB kit sits third from last place in the table. Cinebench 2024 In the Cinebench 2024 multi-core test, G.Skill's Trident Z5 Neo RGB DDR5-6000 C34 128GB kit is in the lower part of the results table, but it is faster than the two other Trident Z5 Neo RGB DDR5-6000 kits we've tested. Encoding Benchmark Handbrake In the Handbrake test, the Trident Z5 Neo RGB DDR5-6000 C34 128GB kit sits near the bottom of the results chart, but in reality, there is hardly anything in it between it and Klevv's Urbane V RGB DDR5-7600 C36 kit that sits at the top of the table. Office Productivity Benchmarks PCMark 10 Essentials Productivity Digital Content Creation When tested with PCMark10, G.Skill's Trident Z5 Neo RGB DDR5-6000 C34 produced a mix of results. Compared to other kits in the list, it performs best using the Productivity traces, and then Digital Content Creation. The worst performance came from the Essentials test. Gaming (1080p) Benchmarks Total War Pharaoh - Battle In the Total War: Pharaoh – Battle benchmark using Ultra quality settings, G.Skill's Trident Z5 Neo RGB DDR5-6000 C34 average score of 130.997 fps puts it firmly in the lower half of the results table, but truth be told, there's not a lot between any of the modules in the list. Backing off the quality settings to Low sees the memory dropping to the last position in the results chart. Final Fantasy XIV-Dawntrail There's not much to choose from among all the kits in the Final Fantasy XIV Dawntrail benchmark using either the Maximum or Standard image quality settings. Cyberpunk 2077 In Cyberpunk 2077's benchmark, the memory sits in fourth from the bottom of the results chart when tested with Ultra image settings. Switching over to the low-quality settings sees the drive shoot up the chart to fifth position with an average fps score of 185.92 and a 1% Low figure of 133.87 fps. It wasn't that long ago that if you wanted to fit a system with 128GB of memory, you would need at least four memory slots to fill up with modules. With the advent of denser memory chips, you can now get to 128GB using just two modules. One company that offers 128GB memory in dual kits is G.Skill, offering (at the time of writing) the kits in five product lines: Trident Z5 Neo RGB (DDR5-6000), Trident Z5 RGB (DDR5-6400, DDR5-6000), Trident Z5 (DDR5-6000), Flare X5 (DDR5-6000), and Ripjaws S5 (DDR5-6400, DDR5-6000). The memory kit that G.Skill sent in for review was one from the Trident Z5 Neo RGB range. The 128GB DDR5-6000 kits are available in three latencies: CL32 (1.40V), CL34 (1.35V) and CL36 (1.25V). The CL32 has EXPO support only, while the other two support EXPO and Intel's XMP technology. The CL34 kit utilises two dual-rank 64GB modules, each comprising sixteen 4GB Samsung chips (K4RBH086VM-BCWM – M-die). Along with the ICs, there is a Richtek RTQ5132GQWF power management IC (PMIC). The Trident Z5 Neo RGB range uses heatsinks that are made from aluminium finished in (in the case of the review sample) matte black with a black brushed-aluminium insert (a matte white finish is also available). The spreaders give the module a height of 42.8mm. The top of the module is home to the RGB defuser bar. The RGB system comprises eight LED segments per module. These LEDs are very bright, but they can be turned down in the software. There are two options to control the RGB, G.Skill's Trident Z Lighting Control utility, which can be downloaded from the G.Skill site or via the motherboard software. The Trident Z Lighting Control supports up to four independent profiles with their own custom light setup. The software has fourteen lighting effects and a wide colour palette, and modules can be synced or set up as individual units, so pretty much the sky is the limit when it comes to custom schemes. If you want the memory to be integrated into an existing light scheme, most of the 3rd party software is catered for with support for ASRock Polychrome Sync, Asus Aura Sync, MSI Mystic Light Sync and Gigabyte RGB Fusion 2.0. We found the 128GB kit of G.Skill's Trident Z5 Neo RGB on Amazon.co.uk for £389.86 (inc VAT) HERE. Pros: Kit capacity. Performance. Build quality. Cons: Only one memory profile each for XMP and EXPO. Some test results were a little disappointing. Pricey. KitGuru says: If you are looking for a huge capacity dual module DDR5-6000 kit then G.Skill offer several amongst their product lines. The Trident Z5 Neo RGB 128GB kits come in three latency versions, the C34 version sitting in the middle of the three. The Trident Z Lighting Control supports a mind-boggling number of options, so the sky is pretty much the limit when it comes to lighting schemes for the modules.
