Corsair introduced a new series of Vengeance RGB DDR4 memory modules that feature a revised heatsink design and multicolored LED lighting. The Corsair Vengeance RGB RT DDR4 memory modules are availabl... Corsair Silently adds Vengeance RGB RT DDR4 Memory Modules optimized for AMD platform
XMP began as an Intel optimized bios shortcut/preset. and for years you could buy optimized RAM for either AMD or Intel platforms. only real difference was whether they were recommended by the mobo manufacturer. and the XMP settings matched the mobo if you bought the right memory. plenty of people over plenty of time have had to manually adjust timings because they bought RAM w/o using the ramchecker.
Ryzen requires certain tertiary timing considerations to achieve stability that often renders a system unstable if not met.
o.k. time lapse blow by blow... especially since DDR4, but certainly before then - Intel would push the "tock" with faster cpus w/ new uArch, typically HEDT/Xeon with higher DDR speeds (and timings), the RAM would have to be optimized for the platform (at first same but OC RAM with OC speed) and that was a drag. then they released XMP to eliminate the necessity of manual timings. RAM compatibility mode leaves the RAM running at lowest system value, whereas XMP automatically gets a "sweet" clock for the RAM being used so there is a difference between compatibility and optimization for AMD, Ryzen loves an OC for the RAM and gives extra performance because of the intricacies of Infinity Fabric, so optimization for that is real as well.
