AMD EXPO 1.2 could supercharge Ryzen CPUs with CUDIMM support amid global DRAM crunch — full AMD CUDIMM support is on the horizon

AMD EXPO 1.2 is anticipated to introduce CUDIMM support for Ryzen CPUs, potentially enhancing memory performance amid the global DRAM shortage. The CKD technology in CUDIMMs allows for faster and more reliable memory operations. While Intel has already integrated CUDIMM support, AMD is gearing up for full compatibility with the upcoming Zen 6 processors. The optimization of the CA bus is crucial for unleashing the full potential of CUDIMMs, which are rapidly advancing towards DDR5-10000 speeds. With DDR5 prices expected to stabilize by 2027-2028, AMD's strategic timing for CUDIMM support aligns with the Zen 6 launch window in late 2026 or early 2027.
