Best PPT,TDC,EDC values for 65watt cpu

Go to solution Solved by Chris Pratt,

There are no best values. It's unique to every chip and rig. My "best" values for my 5900X changed from switching power supplies. The one you need to pay attention to is EDC. Find the value that gives you the best performance, while ensuring that PPT and TDC are not limiting you (both less than 100%). Then, adjust PPT to where you're hitting 100% on that and EDC at load. Finally, adjust TDC the same, to where you're hitting 100% on all three.

I've tried numerous settings and testing them by using CB R23. The best score I got was 6519 and that was having PPT 85, TDC 55, EDC 80. I'm still learning and I was a little confused by lower the values from 88,60,90 actually gave me better results. Any help would be greatly appreciated.

Change to the correct PPT limit I had when I got the best score.

Oh so that's the correct way! So make them all to where they are hitting or sitting on 100% ? Could you please just let me know if they should be hitting 💯 on all 3 or pegged on all three. I appreciate your help.

They should touch, it really depends on the type of load the cpu is receiving. Hit it with a heavy load and you will hit edc fairly easily. You want something light but substantial to let the cores stretch their legs. It really is a bit of a balancing act. What works for me might bomb for you. The CPUs are not consistent, each of them are different.

This is my son's computer and I'm always trying to improve performance for him but in all reality he could care less.🤔😁 All he really does on it is game,watch videos, and stream with his friends. So basically you are saying with a normal load they should still have a little breathing room but at heavy load be pegged? Yeah it is definitely a tedious operation but to be honest with you I'm really enjoying learning. Thanks for your input. I appreciate it.

I had a 3600XT for about a month or two.. I didn't bother with PBO much, I didn't really like how it worked.. I focused on all core clocks with that CPU. No PBO, no boosting, 1 clock 1 voltage. I was able to run it at 4400 with 1.2375, and 4500 with 1.3375. The 4500 was not good for all loads just because of the voltage I had to use. 4400 was good for everything. And I was able to run my Le Grand Macho RT with no fan on that CPU running at 4400. Pretty schweet.

Yeah that's definitely sweet. 4400 at 1.23 is awesome. Was it stable at that? I'm sure the 4500 at 1.34 basically got pretty warm. I've tried an all core frequency but it just doesn't do that good with the 3500 because the best thing about this processor is the single core performance and that just kills it. I'm going to upgrade the processor soon and I was thinking about 3700x or 3600 what's your opinion.

Yessir, Linpack Xtreme and everything else. 4500 was good for everything except Linpack.. she got warm with it. And its a lot of voltage for Zen2 imo. 

 

If it were me looking for a CPU, I would be looking at Zen3, any of them. I have a 5600X and it is a sweet little CPU. Its a good thing I didn't sell it, because I think I am going to sell my 5900X.
