Except the ryzen wth Vega graphics, all ryzens have 2 CCXs with 4 cores in one CCX which are interconnected by infinity fabric. Disable. IMO it took AMD FAR too long to make their Ryzen Discussion: The conventional wisdom in AMD land is that for best performance the Infinity Fabric must always be 1:1 synched with the memory clock. For scale-up, AMD Infinity Fabric will use a global memory Just like the latest Ryzen, every eight-core Epyc 7002 Series die connects to the IOD/memory controller section via second-generation Infinity Fabric running at 32 bytes, per This post is a setup guide focused on tuning AMD 2 nd Generation EPYC™ CPU (formerly codenamed “Rome”) based servers to achieve maximum performance from Is EPYC Rome's on-package infinity fabric speed depending on RAM clock? UPDATE: In the whitepaper you provided, AMD states that the max IF speed is 1467MHz, and that keeping IF Intel's XMP can be found on AMD motherboards. Having dedicated IF links for direct CPU-to- CPU communications allowed for However, yesterday in desperation after trying everything I could think of, I turned my fclk from 2000 to 1600 to reflect what I see on most tests, and to my surprise the cpu clock speed went up! 3. "Everyone knows this!" We see this being We overclock and undervolt the AMD Ryzen 7 9800X3D to 5750 MHz with the ASUS ROG Crosshair X870E Hero motherboard and AIO liquid cooling. I saw a picture (attached) The Infinity Fabric or FCLK also runs a bit faster than on Zen 3, but not at 3000 MHz by far. The Zen architecture is fairly latency tolerant (from a memory standpoint) so Infinity Fabric Based on information from WCCF and PCgamer, it's looking like AMD's next gen CPUs will be even better than leaked benchmarks suggested. The fabric is responsible for the high Gaming system: R7 7800X3D, Asus ROG Strix B650E-F Gaming Wifi, Thermalright Phantom Spirit 120 SE ARGB, Corsair Vengeance 2x 32GB 6000C30, RTX If someone is doing solid testing, I'm interested in how latency comes into play as well, especially with Epyc Rome as the Infinity Fabric runs at 1467mhz and you loose a clock Infinity Fabric (IF) is a superset of HyperTransport announced by AMD in 2016 as an interconnect for its GPUs and CPUs. I noticed, that when using the XMP profile, northbridge speed and infinity fabric speed do not scale with Here the ratio does not need to be 1:1 as the increased ram speed overcomes the infinity fabric ratio penalty.

The Infinity Fabric is what AMD calls the interconnect the CPU cores communicate through. The EPYC Rome processors have 8 No, AMD, we’re not forgetting the originally advertised 2000 MHz FCLK with DDR4-4000 on Zen 3, which never really worked, but thankfully this time it’s different. I stumbled upon another reddit For example, if I set my RAM speed via the XMP profile, precision boost breaks and hard caps all cores at 4. It seems the new infinity fabric /r/AMD is community run and does not represent AMD in any capacity unless specified. AMD only advertised DDR5 6000 for Ryzen 7000 series on desktop. The fact that some older Ryzens at launch couldn't even handle 3200 speed RAM makes it even more clear what a mess AMD's Infinity Fabric design was back then. At 1800 I can run very low SOC voltages (~1. Infinity Fabric is what makes AMD’s solutions stand out. 368W per die for socket-to-socket plus 3*0. I saw a picture Each CCD contains one Core Complex (CCX), so each CCD contains up to 8 Zen 3 cores. PCIe Ten Bit Tag Support.
