Key takeaway from this video: AM5 does not report WHEAs for correctable infinity fabric errors, in contrast to AM4. The difference is minimal. The MCLK is 1599. 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. Consequently, there can no longer be a 1:1:1 config with DDR5-6000, as there was with Zen 3. The advertised speed is the transfer rate in MT/s, not the frequency. U should aim for 6000-6400mhz first before infinity fabric Oct 30, 2023 · FCLK is the Infinity fabric, that seems to need to be within a certain multiplier range of the MCLK - any value dividable by 0. Double check in CPUZ if you aren't sure. One theory is that Zen 4’s DRAM bandwidth is limited by the link between the memory controller and fabric. In addition to 1.

BZ recommends Y-cruncher VST for validation, but I figure you might still need to performance validate infinity fabric overclocks as you will not get WHEAs telling you that silent errors are affecting your performance. 1900 got me to the Windows login but everything was frozen then after 20 seconds it rebooted on its own. Infinity fabric clock is automatically set to be equal to UCLK, though it can also be manually set to something else as you please. So the memory controller is much better than Intels in that it can run dual rank configs to at least 6000 mt/s, and it seems to run pretty tight at single rank 6400, comparable to Intel platform, but then it completely shuts down single rank above 6400 mt/s. Our memory frequency will be DDR5-6800 which is 3400 MHz. BTW, DDR means double data rate. I noticed in my bios that my memory is achieving a frequency of 4831. I have the Aorus B450 Gigabyt Elite motherboard and I didnt see any options in the bios to change the frequency. Manual: FCLK must be less than or equal to MCLK for best performance in most cases. Anytime you see it listed as MHz, it's technically wrong. Doubling the data rate from 1333 to 2666 MT/s grants a 46% performance Já no passado discutimos e definimos o que é o Infinity Fabric da AMD, o método de interconexão dos diferentes componentes que compõem os processadores AMD Ryzen. At RAM clock rates beyond 6000 Mbps, the UCLK automatically goes into 1/2:1 mode, better known as 1:2. This forces the memory controller to run at half the frequency of the system memory.
