luca2 Posted October 16, 2022 Share Posted October 16, 2022 Hi, After reading some posts about this topic I could not find anything specific for a 5900x. I want to assign 8 cores to a vm. Just curious if anyone has done this before and can share with me his experience. This are the core pairs: I guess they are paired like this because they are the SMT pairs, right? After further reading I found this: "The 12-core Ryzen 9 5900X and 16-core Ryzen 9 5950X are parts that have two 8-core CCDs besides the cIOD. The 5900X is carved out by disabling any two cores per CCD"... Can I assume that 1 CCD has cores 0-11 and the second CCD has 12-23? Rgds Quote Link to comment
TGudde Posted October 19, 2022 Share Posted October 19, 2022 You can use LStopo to find out the correct cores and cache topology of your CPU. Spaceinvader1 made a video about it! I happen to have a 5950x running so i can tell you that for me the correct pair are Die 1: 0-7(HT16-23) Die 2: 8-15 (HT24-31) 1 Quote Link to comment
