G.Skill Trident Z5 NeoX w/ EXPO ULL!

G.Skill has sent us two kits of their new Trident Z5 NeoX RGB DDR5 memory that features AMD EXPO Ultra Low Latency technology. The claim is that we will see 4% improvement in performance with absolutely no work required. Naturally those were claims we simply had to check.

Key features

• Designed for AMD Ryzen desktop processors and the AMD AM5 platform, the Trident Z5 NeoX RGB series memory kits are engineered to achieve up to their rated speeds when the “AMD EXPO Technology: Featuring Ultra Low Latency” memory overclock profile is enabled in BIOS. The AMD EXPO ULL memory overclock profile includes G.Skill tuned sub-timings that deliver greater performance on supported hardware and BIOS. It is the ideal memory solution for PC enthusiasts to build a high performance AM5 platform for PC gaming or content creation.
• Extra Tuned Sub-Timings for Extra Performance Potential
  Going beyond memory frequency and primary latency timings, the Trident Z5 NeoX RGB series is engineered with optimised memory sub-timings to further improve latency and memory performance when AMD EXPO ULL profile is enabled. Enabled by “AMD EXPO Technology: Featuring Ultra Low Latency”, G.SKILL is able to fine-tune a broader range of memory parameters than before, unlocking additional performance potential for gaming, content creation, and memory performance demanding computing workloads.
• Engineered for Performance and Quality
  Built with carefully screened DDR5 memory ICs, the Trident Z5 NeoX RGB memory kit is rigorously validated to ensure exceptional performance, quality, and stability on supported hardware configurations for PC gamers, enthusiasts, and performance-focused PC users.
• Experience Extreme Performance of AM5 Systems
  The Trident Z5 NeoX RGB is optimised to complement modern AMD Ryzen desktop processors. Combined with optimised overclock timings in the AMD EXPO ULL memory overclock profile, this memory kit is designed to extract extreme performance from AMD AM5 platforms.

Geekbench 6.7 Multi Core

In Geekbench 6.7 Multi Core the two blue bars are for Ryzen 7 9850X3D and the five yellow bars are Ryzen 7 9700X. We can clearly see that EXPO ULL gives a small advantage over regular EXPO settings.

The AIDA64 Memory Copy shows EXPO ULL running well on the G.Skill Trident Z5 NeoX RGB kits.

Assassin's Creed Mirage at 1440p

In Assassin's Creed Mirage at 1440p we can plainly see that EXPO ULL has minimal benefit for a Ryzen 3D CPU and delivers around 3% boost for a regular Ryzen 7 CPU.

Closing Thoughts

AMD claims that EXPO Ultra Low Latency will deliver small benefits over regular EXPO, and that lines up perfectly with our own findings. The inner workings of EXPO ULL are completely invisible to the end user and place the burden on the motherboard companies who have to carry out more research while they are developing their BIOS files, which we consider to be excellent news for the customer.

The snag, obviously, is the current outrageous cost of DDR5 memory. There is very little chance you are considering a memory upgrade for your PC on your existing set-up. This means you are only likely to encounter EXPO ULL when you either build a new PC or carry out an extensive upgrade, perhaps when AMD launches Zen 6 early in 2027.

Pros:

• EXPO ULL gives a useful boost over regular EXPO
• One click to enable – the BIOS does all the work
• Rock solid stability

Cons:

• Buying any DDR5 memory at present is a grim experience
• 3D Ryzen CPUs have less to gain than regular CPUs

KitGuru says: G.Skill Trident Z5 NeoX RGB gives us a clear and welcome view of AMD EXPO ULL technology.
