For the 5950X this value is very important because given the chance your CPU will not hesitate going there given the workload. This should be a good starting point as the values to pick for PPT, TDC and EDC.įor people who want to go further, you should play with TDC and EDC combo for higher results, even a small variation can be enough to squeeze a bit more performance.Ģ00W is enough for 5600, 5800 and maybe 5900X SKUs. Observe TDC, EDC and PPT values and check what % of the max you are hitting. Once you do this, boot into Windows, open Ryzen Master and start CB23 multi thread test.
#Zen bound ii manual#
In the advance section of PBO, set PBO limits to motherboard or manual and set values that you won’t realistically hit. Load up BIOS defaults, go into PBO menu and enable advanced. Further testing for those who want can be done. There’s 2 approaches to these limits and I will share the approach that is more user friendly but not the one that will necessarily yield better performance. Also, SKU matters, the values for a 5600X are absolutely not the same as the ones for a 5950X, The value for these limits varies hugely from CPU to CPU, some CPUs scale differently, specially with TDC and EDC combo.
Inside your BIOS**,** enable PBO and select PBO advanced, this will bring up a bunch of options:
#Zen bound ii software#
Other software to validate performance gains such as Cinebench R20/23, 3D Mark suite, Geekbench,gaming benchmarks, etc, can be also used. Ryzen Master ( ) - Tool to monitor % of TDC and EDC values during testing. Props to blu3dragon from OCN for this tool. OCCT ( ) - All in one stability testing tool, very good, also support the developer, really nice guyĬoreCycler ( ) - Very decent tool to complement OCCT, to test each core individually. HWINFO64 ( ) - Monitor temperatures, clock speed, voltages, etc.ĬPU-Z ( ) - Quick and dirty benchmark for single and multi-thread performance Some of the things in this guide will vary from CPU to CPU due to but not only, silicon quality variation, cpu SKU (5600, 5800, 5900, 5950X), cooling method used, RAM setup, Operating System bloat, etc. AMD ZEN 3 PBO & CURVE OPTIMIZER OVERCLOCKING GUIDEīy unlocking PBO limits you are violating AMD’s stock configuration and therefore invalidating your WarrantyĮven though this guide is aimed at everyone, I am expecting you to at least know some of the basics about how ZEN cpus work, this includes PBO, PBO limits, navigating BIOS, troubleshooting potential issues that arise, etc.
