2023年2月27日 · For example, you can check the "Core Complex ID" (CCX ID) information provided by the CPUID instruction, which identifies the particular CCX within a CCD. In summary, while it's not possible to directly read the number of CCDs from the CPUID instruction, you can use other information such as the CCX ID to infer the number of CCDs.

2023年9月23日 · Hello! I looking for information about cores layout in CCX. On official AMD diagrams it just show "Core", but no actual numbers which core is which. Like Core #0, Core #1 e.t.c. I have got Ryzen 7 5800X3D, so it's 8 cores CPU (Core #0 - Core#7). My best cores are #0 and #7, so they are on opposite s...

2019年8月8日 · The test found that the core frequency of the ZEN2 processor CCX is uniform, or there is a floating of 25/50/100Mhz. Manually set different frequencies for different cores in CCX. If there is a high probability, the core frequency will fall to a lower level. If there is no problem setting the unified frequency.

2020年4月20日 · Hello All, I'm kinda stuck, in Ryzen master I can't change anything because it is showing one of my cores disabled. However, in HWinfo64 and task manager it shows all cores active. I went thru bios and couldn't find any disabled cores and I checked to make sure windows wasn't disabling any cores. I...

My understanding is that each CCX shares a level 3 cache with all cores contained within that CCX as well as a private level 2 cache per core. If a thread moves to a core within the same CCX, the cached data can be copied from the level 2 cache of the original core, to level 3.

2022年6月10日 · Meaning that there is no AMD EPYC processor (apart from some embedded models) which can be used to run Oracle DB SE2 software. This renders some bizarre cases where there is for instance only 1 active core per CCX (7262), meaning that Oracle counts this chip as 8 sockets, while this chip only has 8 cores.

2023年3月3日 · A CCD, sometimes also called a "chiplet", is a cluster of eight CPU cores that share access to a common L3 cache. Some AMD CPUs, like the Ryzen 7 7700X and Ryzen 7 7800X3D, have one active CCD per physical processor. Higher-end chips in the Ryzen 9 Series have two active CCDs, typically referred to as CCD0 and CCD1.

2021年4月10日 · Running 4000/2000 at CL16 without WHEA 19 is my goal eventually. It may require trying a 5800X or 5900X since they are 105W parts and seem binned better. Rumor has it the 5800X has the same CCX as the 5600X just 2 more cores, so it could be an epic waste of money over the tried and true 5900X having the ability to get to the 2000 FCLK.
