However, given the design of Infiniti fabric clock is the speed of your cpu is communicating with your ram, if you will. For example, the Infinity Fabric (FCLK) now runs independently of the RAM controller (UCLK) and RAM (MCLK) and has its new sweet spot at 2000 MHz, which is also set automatically when loading EXPO or XMP profiles. It is also usable as interchip interconnect for communication between CPUs and GPUs (for Heterogeneous System Architecture ), an arrangement known as Infinity Architecture . 0 or greater, before 1. If you manually select a specific frequency for the infinity fabric (as the pic shows), it will probably declock from memory, and both will run independently. e. The MCLK is 1599. So If your Flck is not the same as your ram speed you will lose performance. 3600 is a sweet spot because zen 2 infinity fabric often can’t go above 1800 and benefit from a higher ram frequency. 2 Connecting the Accelerator with Infinity Fabric™ link Relevant information prior to connecting cards through Infinity Fabric™ link should go here. BTW, DDR means double data rate. The 256-bit Infinity Fabric crossbar ties the resources inside of a Zeppelin die together. Even after selecting the XMP profile to 3200 mhz and FCLK to both auto and 1600 mhz, I am still seeing the ram is running at 1330 mhz . AMD says that a future AGESA update will improve Infinity Fabric overclocking and as a result 1:1 memory overclocking as well, but at this point who knows if it will help across the board. Infinity fabric clock is automatically set to be equal to UCLK, though it can also be manually set to something else as you please. With amd you never ever want a manual clock and voltage oc. Operating at the 1800mhz, the "infinity fabric" system also sync runs at 1800mhz, which is IF's max freq. 2. Under overclocking -> Infinity fabric Frequency and driver should I leave to auto or should I change it to 1600? When it was on auto it was showing 3208 in the bios. For optimal performance, maintaining a 1:1 ratio with memory clock frequency is recommended.
