AMD is bringing a new automatic memory overclocking feature out, dubbed EXPO Ultra Low Latency (ULL). The new tool promises a 13% uplift in average performance across over 30 games compared to JEDEC standard speeds for DDR5, as well as a 4% uplift compared to standard EXPO, at least according to AMD’s internal benchmarks. The company hasn’t said when ULL will be available, but it has several memory partners lined up to support the feature.
We don’t know much about how EXPO ULL works, and more specifically, where AMD is finding improvements compared to standard EXPO. Despite that, AMD shared some broad benchmarks looking at EXPO ULL performance on a Ryzen 7 9700X CPU in over 30 games. AMD didn’t share resolution (presumably 1080p) or settings details for the titles, outside of the fact that they were tuned for “best performance.” You can see the full configuration in the gallery below.
Compared to JEDEC-standard DDR5-5600 CL46, AMD shows EXPO running at DDR5-6000 running 9% faster, and DDR5-6000 CL30 with EXPO ULL running 13% faster. Looking at 1% lows, AMD claims a performance improvement for EXPO and EXPO ULL of 11% and 15%, respectively. AMD didn’t clarify the CAS Latency of the standard EXPO memory, but it notes that it tested at CL28, CL30, and CL36 for both EXPO and EXPO ULL.
AMD simply says that EXPO ULL is “coming soon” from major memory partners, including G.Skill, Kingston, Klevv, Lexar, Origin Code, TeamGroup, V-Color, and XPG.
There are still several lingering questions about ULL, which we hope to learn more about on the ground at Computex 2026. Presumably, ULL isn’t a feature that’s being backported to older EXPO DIMMs, but rather a new standard moving forward. AMD hasn’t confirmed that’s the case, however.
We also don’t know what ULL is actually doing to find 4% extra performance compared to standard EXPO. Given the wide swath of games and CAS Latency settings AMD tested at, there’s a good chance ULL won’t show a benefit in all games. We should see better uplifts in smoothness, however, as evidenced by AMD’s 1% low results.
Tom’s Hardware is on the ground in Taipei for Computex, where we’ll be meeting with AMD to learn more about EXPO ULL, along with the newly-announced Ryzen 7 7700X3D and reintroduced Ryzen 7 5800X3D.
