Taking the stage at Computex, AMD introduced the EXPO Ultra Low Latency (EXPO-ULL) memory overclocking standard. EXPO supported RAMs have already been on the market for a long time, EXPO-ULL is the next stop. What is EXPO, what is the difference between EXPO-ULL? Overclocking with RAM can be much more complicated than CPU overclocking. That’s why there are ready-made overclock profiles such as XMP and EXPO. RAM profiles take up a small, inaccessible space in the memory, and it is very easy to access ready-made settings from the motherboard’s BIOS.
Thanks to ready-made memory profiles, we can increase our memory to the high speeds specified on the box with a single click. EXPO was doing this job, while “ULL” will provide “low latency profiles” as its name suggests. EXPO-ULL RAMs marketed for AMD systems will enter our systems with extremely low memory timings. Ryzen 7000 and Ryzen 9000 Series processors were more limited in terms of memory speeds compared to Intel’s DDR5 platforms.
However, there was still some headroom in Ryzen CPUs when it came to timing. Memory manufacturers were marketing their mid-level DDR5-6000 and DDR5-6400 memories under the name “EXPO” with timings specific to these speeds. With AMD’s latest move, DDR5-6000 and DDR5-6400 kits with lower timing values are now starting to hit the market. Memory manufacturers participating in the EXPO-ULL program include G.Skill, Kingston, Klevv, Lexar, Team Group, V-Color and ADATA XPG.
The red team shared first-party tests showing that EXPO-ULL memory provides up to 100% FPS increase and an average 4% FPS increase compared to general JEDEC memory kits. David McAfee, AMD’s VP and GM of Ryzen and Radeon, said: “EXPO has evolved and we’re working with all the module suppliers. We saw an opportunity to add more sub-timing to the SPD profile and get some lower latency.” The memory will come with a different brand logo, including a new badge.
So, when shopping for RAM, you will notice that the products are different. You already know that memory prices have increased recently. Fortunately, there is no reason to increase the price of ULL badge kits. AMD manager McAfee confirmed this firsthand. No release date for the new standard was specified. Leading RAM manufacturers will release “ULL” supported memory throughout 2026. How does EXPO-ULL perform? The new standard promises an increase in average performance across 30+ games compared to JEDEC standard speeds for DDR5 and a 4% increase over standard EXPO.
At least those are AMD’s test results. AMD showed that EXPO running at DDR5-6000 is 9% faster compared to the JEDEC standard DDR5-5600 CL46. EXPO-ULL running on DDR5-6000 CL30 seems faster. Looking at the 1% lows, they claim a performance increase of 0 and 100 for EXPO and EXPO-ULL respectively. The company hasn’t announced the CAS latency of the standard EXPO memory, but it has been tested at CL28, CL30, and CL36 for both EXPO and EXPO-ULL.
EXPO-ULL release date The company hasn’t announced when ULL will be available, but it has prepared several memory partners to support the feature.
