AMD’s Extended Profiles for Overclocking (EXPO) technology is receiving an update with version 1.2. According to the latest HWiNFO v8.35-5890 Beta, this tool has added support for AMD EXPO 1.2, even though AMD has not officially released this version yet. Currently, AMD employs EXPO 1.0 with its Ryzen processors to provide optimal overclocked memory profiles for each configuration. This approach enhances overall system performance and gives the Infinity Fabric, which interconnects the CCDs and IODs, perfect balance of latency and speed.
What will come with EXPO 1.2 remains a mystery. Recently, as part of the “Granite Ridge” Ryzen 9000 X3D series, AMD’s upcoming Ryzen 7 9850X3D processor was seen running with 9,800 MT/s DDR5 memory, which is unusually high for its class in this late-cycle “Zen 5” SKU. AMD could bring some late-stage “Zen 5” memory profile optimizations that we haven’t seen so far, just in time for the late cycle X3D SKUs.
Update 22:15 UTC: According to AMD insider and author of HYDRA, CTR, DRAM calculator for AMD Ryzen 1usmus on X, the EXPO 1.2 will finally include support for CUDIMMs. These are DDR5 modules with integrated clock driver circuits, which improve signal integrity at higher frequencies, allowing the DDR5 modules to reach frequencies beyond JEDEC-provided range. We still have no idea how AMD plans to implement this. The slide below is just for illustrative purposes and is AMD’s earlier mention of EXPO. It does not reflect the latest 1.2 version.
