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

Trident Z5 CK.

HWiNFO, a popular system monitoring and diagnostics utility, just added support for AMD EXPO 1.2 overclocking profiles, kicking off a wave of speculation about improved support for the best RAM on the market today.. According to renowned AMD utility developer 1usmus, EXPO 1.2 is set to finally unlock CUDIMM support for AMD Ryzen processors — some of the best CPUs.

DDR5 blazes past speed limits by tapping into client clock driver (CKD) chips—paving the way for cutting-edge CUDIMMs. Without getting too deep into the technical details, the CKD acts as a signal booster. It helps keep the signals strong and clear, allowing CUDIMMs to run faster and more reliably than standard DIMMs. It allows memory manufacturers to push DDR5 speeds even higher.
