I'm really enjoying CTR 2.1 on my 5900x. I like the granularity that I can tune based on workloads. What are safe voltages for the PX profiles? I have "high" set at 1.475v and it droops 1.45 to 1.46 under load for 1 or 2 core stress testing. If I use PBO with curve optimizer those are the exact same voltages that I get. Is it safe to push up to the maximum 1.5v (droop to 1.47 to 1.48)? Also, for the P1 profile I set 1.325v with a droop to 1.26v under load (again same voltages as when I use PBO). Can anybody comment if this would be a reasonable way to set voltages and push clocks safely? I'm a little lost when it comes to PX mid and low as my understanding is mid is for loading the top 4 cores and low is for loading all 6 cores in CCX1.
 
Does anyone know why this happens to me? From my understanding, the tuned voltage and ppt should have dropped, not gotten higher. This happened with 2.0 RC5 as well and I'm quite lost. All of the settings in the BIOS are set to what they should be as specified by @1usmus in the guide. I also must have a less than ideal sample, as the default registers below what a default 5900x would show unless there are any other theories about this:

Been getting good results with CTR2.1 on my 5900X. I had the bios compatibility issue in the past, but no problems with CTR 2.1 RC5. I've had the profiles stuck once, but deactivating and reactivating all 3 profiles fixed it.

4.575 / 4.525 @ 1.200 P1
4.650 / 4.575 @ 1.250 P2
4.675 @ 1.325 Px Low
4.775 @ 1.375 Px Mid
4.925 @ 1.425 Px High

No, the tuned voltage and power consumption does not necessarily have to drop after tuning in CTR. It depends on what your defaults are. If your bios is set to default, you might see an increase like you did. If your bios was set to PBO, then you'll see a decrease.

Your profiles look great, so don't worry about it.
 
Nice release, i got promising results but there is one thing that bothers me.. HWInfo shows an Effective clock of 8,120GHz sometimes and the CPU Die reports 121°C temp max. Should i be worried?
I too ran into this, scared me for half a second then I saw that my CPU CCD1 and CCD2 temps were both at a max of like, 78c, so I doubt the cpu die average really hit 120c! Certainly I didn't intentionally throw any wild loads at it so unless it stuck to the px high voltage and tried to run all core or something... seems it must just be a bug. I also have seen odd frequencies like an effective clock rate of >10ghz. I wish!

For reference, I have a 5950x on a crosshair VIII formula.

Thanks for the reply! You indicated that enabling PBO would result in a decrease - is it that simple? In the guide, it says to leave PBO as either auto or disabled, and I tried with both options but got the same result. If there is anything else I can try with PBO that would be cool, but I won't worry about it if there is nothing else to do.

Your default frequency is also 3700. So you have disabled core performance boost in the bios and the cpu was not boosting. It wasn't in the default mode it seems because cpb is enabled by default (not pbo).
 
On my 3900X I noticed something similar that can be related. When I close CTR after being used for a while in Hybrid OC mode, the CPU get stuck on the last mode (Idle, PX, P1 or P2) it was just before closing the program.

It's dangerous because if it got stuck at any of the PX modes, you end up with a CPU at a fixed 1.4x Vcore and it remains that way at any workload you put on the CPU later on, so if you put a high load on it you would be in a situation where all cores are used at 100% load and the CPU is at 1.4x volts and very high temperature, borderline in a possible degradation situation if you don't notice it.

I had this bug in CTR 2.0, solved then in CTR 2.1 RC 4, and it's present again on the latest RC 5.

@1usmus Can you take a look at it?

Thanks.

Edit: It's stuck on Idle or any of the PX modes, whatever it was active before closing. P1 and P2 are not affected it seems. Also, if I deactivate PX profile before closing the app, the CPU effectively returns to the stock operational mode. So in summary, CPU get stuck only at idle or PX if you close the program without deactivating PX profile first.

I have a 3900x as well and it looks like its doing the same thing if PX is active it ignore P1 and P2!! If i deactivate it it runs at stock and still ignores P1 and P2...
 
Does anyone know what exactly is "OB testing?" I can't get it to enable it no matter what, and occasionally when the overclock crash you can select OB limit on the profile page, does anyone know what exactly is that?
Also reading through the profile page for PX, P1, and P2 there's a setting for "OB_CCX*", "OB_*_INDEX", what exactly are those? every initialization of the CTR2.1 it talks about OB# and OB limit, but looking on forum information on it is very minimal aside from Chiphell which I had to use google translate to minimal understanding.

No, that wasn't what I meant. CTR 2.1 compares power usage based on the CB R20 that is run during diagnostics, before tuning. So if you had PBO on when running diagnostics, you'll most likely end up with a high consumption before tuning, which then shows a lowered power consumption after tuning. If I use the following example values:

Full default bios: 105W consumption (say it got CB R20 score of 8000)
PBO on: 180W consumption (CB R20 score of 8800)
CTR 2.1 tuning: 1340W consumption (CB R20 score of 8800)

So depending on what your starting point was, you could see that CTR2.1 either increased your power consumption by 25W, or reduced it by 20W. Ultimately, what is important is your score after tuning and what the power consumption is for that score. Then you just need to look at score per watt of power.

Here are my actual results with CTR 2.1 on my 5900X.
Before CTR 2.1, using PBO2
CB R20 - 8591 - 190.13 W (4.450 @ 1.35V) - CPU temp of 80ÂşC
CB R20 - 8544 - 188.73 W (4.700 @ 1.4V) - CPU temp of 85ÂşC (my set thermal limit, the CPU was throttling performance)

After CTR 2.1
CB R20 - 8896 - 141.36 W (4.575 / 4.525 @ 1.2V) - CPU temp of 66 ÂşC
CB R20 - 9073 - 173.27 W (4.700 / 4.650 @ 1.3V) - CPU temp of 73 ÂşC

So PBO2 efficiency is about 45.2 points/Watt.
CTR2.1's efficiency is 52.4 to 62.9 points/Watt for my settings. Because of the higher efficiency at 4.575/4.525 @ 1.2V, this is what I have set my P1 profile to for everyday use.

CTR 2.1 is not magical, but it gives us the ability to set the voltage and the clock speed manually, in 5 separate profiles that can be switched between automatically based on load and core usage. So essentially it is a manual overclock, but you have 5 separate manual overclock profiles. To get the best score/result, it is up to you to find the right values, based on CTR's tuning process.
 
So far, I'm getting the same performance as an all core -20 CO on my 5800X, but with 20 Watts less and less heat.

It's rated silver by CTR and will set the max boost at 4.85 just like default on my CPU, I can get it to boost to 4.9 GHz with AutoOC, but my chip just doesn't have the legs to go past 4.85 GHz.
 
Thats my first test with CTR.I want to inrease the voltages and speeds.Does anyone know how that works cause every time I set something and press calculate it revers back to what you see in the pic.

I think you just input the voltages and speeds and save and activate. Calculate just finds the optimal settings again like going through diagnostic.

You can set it to go past 4.85GHz if you want to. It just needs more voltage (25mV increase for roughly a 25MHz increase), but your cooling and power capacity from your motherboard will be the limit. My sweet spot is 4.7 GHz, as going for 4.75 or 4.80 GHz causes my heatsink not to be able to remove heat quick enough for sustained performance.
 
I own a 3700x. I did diagnostic and it created a PX profile, i increased PPT EDC and TDC values to the max my board (c7h hero) allows and first i pressed tune with 1.375v and reference 4.3ghz, then Tune with 1.25 and 4100 reference. Saved all profiles. I am now using CTR hybrid oc.
Sometimes it crashes while playing overwatch.

How do i stresstest to realize which profile is not stable? Using CTR's own stresstest disables CTR hybrid oc, forces 2 cores to PX High state with 1.40v (obviously everything crashes since i can't hold 4475hz on 2cores with 100% load)
