Been having a play with this with my 5900x and it seems like it can get really good results, although I've not done full stability testing yet.

I went through the instructions and had these as my P1 and P2 with the Hybrid OC

P1:
CCX1 (158): 4425 MHz, 1181 mV OC=
CCX2 (133): 4325 MHz, 1181 mV OC=

P2:
CCX1 (158): 4550 MHz, 1288 mV OC=
CCX2 (133): 4500 MHz, 1288 mV OC=


And then I thought I'd do some runs with Cinebench R23 and compare with Stock and with PBO and these are the results, all readings HWInfo64, voltages are from CPU Core VID (Effective).

Stock:
Score: 20205
Voltage: 1.181v
Clock: 3.975ghz both CCX
Temp: 70.6c
Power: 130w

PBO:
Score: 21606
Voltage: 1.325v
Clock: 4.3ghz both CCX
Temp: 87c
Power: 180w

CTR:
Score: 22398
Voltage 1.181v
Clock: CCX1 - 4.425ghz, CCX2 4.325ghz
Temp - 74c
Power - 140w



So a decent amount better than PBO with stock power limits, 400mhz jump over stock with the same voltages.

My thoughts as well are that if PBO will happly run 1.325v at full load, then I could use that voltage in CTR and get even better results. However I'm a bit reluctant to push it that high, as it doesn't use FIT so could put too much voltage through and cause degradation.


I run my 5800 at 1.325v fixed... PBO pushes mine to 1.3v full load also

Careful with that logic. PBO operates based on all kinds of clever sensors to push this high. It has ways to decide when high voltage should be dialed back. Whereas at fixed overclock there is no plan B.
Have you tested with Stock + negative curve optimizer?

My 5950x is a bronze sample in CTR 2.0, but I knew that anyway from it's boosting/poor curve optimiser results from before.

One things I've found interesting if that I've never bother messing with 'manual' OCs since moving to Ryzen, and there's quite a variance between what PBO does and what a manual OC does that doesn't make a whole lot of sense to me.

With PBO enabled and CO set to max stable. Running CB R23 I get this results:

Average core clock: 4400 MHz
Average core voltage 1.18-1.20 V
CB R23 nT score: ~29,000
CPU power: 225 W
CPU temp: 85 C

With a manual OC set instead using CTR 2.0, I get these results:

Core clock: 4400 MHz
Core voltage 1.20 V
CB R23 nT score: ~29,000
CPU power: 170 W
CPU temp: 68-70 C

Same clocks, same voltages, same performance. Yet 55 W more power on PBO with the CPU temps to back that up. That doesn't entirely make sense unless PBO is just straight up lying about the voltages it's using.

I also experience much higher TDP/temps with PBO with very similar performance vs a manual OC. Yet the voltages are supposedly an entire 100mv less under load with PBO...

Yeah that's why I was taking about possible degradation. I have issues with stability as soon as I touch the curve optimiser it seems. Even putting -5 on a few cores causes huge amounts of errors in occt and makes prime95 fail.

Strange.. the app suddenly wont launch for me ¯\_(ツ)_/¯
Same here Asus Tuf Gaming B550 Plus with AMD Ryzen 7 Pro 4750G will not work with this app with bios version 1801. Anyway my AMD bundles sent back for full refunded due to unstable in normal base clock. Very poor indeed.

my 5950X is a Silver sample at 4.04 efficient. strange though it recommends higher clock speeds than your recommendations.

My P2 is 4600 @ 1.25V

hmm yes that is strange - maybe higher temps for you?

I’ll have to run it again. I seem to remember it in the high 30s though. I’ll give it a proper go when I tear everything down and rebuild it again.
Want to test my old Auros X570 Xtreme vs Dark Hero.

you can see it in the log - no need to rerun - its all there :D CTRLOGS subfolder

Received my 5600x this morning, so been having a bit of a play - tho my MSI B450 board is still on 1.1.0.0 Patch D. PBO boosts to 4650mhz.

Now to let it tune in both profiles.

There seems to be some misunderstanding in this thread about what CTR does. Unlike PBO which just increases power (and therefore heat which could throttle performance depending upon your cooling), clock tuner allows you to get more performance per volt by tuning the performance of each core. The new mode should allow prioritisation of better cores for single threaded applications whilst also allowing multiple cores to share loads optimised to around 6 cores (as used by most games). In pure productivity tasks an all core overclock might be better but overall it will use more voltage and generate more heat. Try running the clock tuner following the guide at guru 3d:
https://www.guru3d.com/articles-pages/clocktuner-2-for-ryzen-(ctr)-guide.html
Make sure to follow the BIOS settings as advised and to benchmark in a game and in cinebench to see real world performance before and after. You should find better power usage for the same performance or more performance after tuning. Like all overclocking your milage may vary.

So Bios 1.2.0.0 was released today for my X470 and I ran the test again which took almost 30 mins.

Edit:

Ok so I Clicked on Tune and my PC restarted right away, now the CTR program doesn't launch when i Click on it :p

Edit 2: to fix the Program not starting

"For the app crashing on startup, I have found the config file in AppData can get corrupted when the PC reboots before the file write is complete as the end of the file is filled with null characters.
Go to %USERPROFILE%\AppData\Local and the config file is in the folder named A, rename it and the app should startup."

The above test was ran with LLC set to Extreme then I read that I should leave it on auto, which I did and ran the test again...
