AMD announced its new memory profile called EXPO ULL as part of Computex 2026. ULL, which stands for Ultra Low Latency, adds a new profile focused on low latency to AMD EXPO technology. The new standard is prepared for DDR5 memory kits used with Ryzen processors on the AM5 platform and enables automatic overclocking and tighter timing settings on supported memories. AMD EXPO ULL reduces DDR5 latency on AM5 systemsAMD EXPO technology enables memory overclocking settings to be applied more easily via BIOS on systems with Ryzen processors.
The new EXPO ULL profile brings a structure that focuses on reducing memory latency rather than increasing frequency. The technology, which comes as part of the EXPO 1.2 update, works with more aggressive timing settings on supported DDR5 kits. According to the data shared by AMD, EXPO ULL provides up to a 13 percent increase in average FPS in games compared to JEDEC DDR5 memory. At 1 percent lower FPS values, an increase of up to 15 percent is given compared to JEDEC memory.
Compared to existing EXPO profiles, an additional increase of up to 4 percent on average FPS and 1 percent on the low FPS side was announced for EXPO ULL. Tests were performed on a system with a Ryzen 7 9700X processor. AMD’s test system used 8-core Ryzen 7 9700X, 32 GB DDR5-6000 AMD EXPO memory, Windows 11 Pro, X870E motherboard and NVIDIA GeForce RTX 5090 graphics card. Testing included the GeForce 595.79 driver, VBS on and SAM/ReBAR on configuration.
Comparison was between DDR5-6000 CL30 AMD EXPO memory and DDR5-6000 CL30 AMD EXPO ULL memory. AMD also tested CL28, CL30 and CL36 memory configurations. In AMD’s testing list, ARC Raiders, Anno 117: Pax Romana, Assassin’s Creed Shadows, Avatar: Frontiers of Pandora, Baldur’s Gate 3, Battlefield 6, Black Myth: Wukong, Borderlands 4, Call of Duty: Black Ops 7, Clair Obscur: Expedition 33, Counter-Strike 2, Cyberpunk 2077, DOOM: The Dark Ages, Dragon Age: The Veilguard, F1 25, Far Cry 6, Final Fantasy Requiem, Shadow of the Tomb Raider, Sid Meier’s Civilization VII, Star Wars Outlaws, Starfield, Tom Clancy’s Rainbow Six Siege, Total War: WARHAMMER III and Warhammer 40,000: Space Marine 2 were included.
A decrease in memory latency was also announced with EXPO ULL. According to the shared information, the new profile reduces the delay by approximately 5 to 7 nanoseconds compared to a standard DDR5-6000 kit. EXPO 1.2 also includes new profile fields such as ULL Enable, tREFI, tRRDS, tWR and VDDP voltage. These fields allow more detailed definition of timing and voltage settings on supported memories. The new profile requires a compatible DDR5 memory kit.
Certified EXPO ULL memory kits will be available as of June 2026. While certified memory partners were emphasized in AMD’s announcement, the list included G.SKILL, Kingston FURY, KLEVV, Lexar, TeamGroup, V-Color, XPG by ADATA and Origin Code. Motherboard and BIOS support will depend on the updates released by the manufacturers. New options for DDR5 settings have recently been added to AM5 motherboards with AGESA 1.3.0.1 and 1.3.0.1b versions.
BIOS updates are required to spread EXPO ULL support to motherboards. In order for users to use the new profile, both the memory kit and the motherboard software must support this standard. AMD positions EXPO technology within the scope of memory overclocking. According to the company’s standard warning, changing processor and memory clock speed, multiplier, timing or voltage values outside official technical limits may void AMD product warranty.
Such settings may also affect warranties offered by the system manufacturer or vendor.
