Explanatory note in the attachment. Tentative release date for early access is February 15.

P.s. my sample silver with 14 default CO for best cores. I assume that there are samples that can operate at 5100-5150 MHz.

P.p.s Windows dispatches which cores to use. No affinity masks, no extra CPU resources are needed for this.

CTR 2.1 HYBRID OC (PX PROFILE)

Rizlah

so excited for this

Can't wait to upgrade my 3700x so I can run a 5ghz Ryzen CPU, just hope my X570 Aorus Master is up to the task 😬

For Zen 2, the numbers will be a little more modest. I think that only XT processors will be able to approach the 4900MHz mark. But in any case all processors will be able to get operating frequency higher than AMD offers.

Really nice! How is PX profile tested for stability?

You may have noticed that the diagnostic result is often the numbers at which the profile will be stable. The PX profile is no exception, but I have made more serious calculations for it. For me, the main task was to find the best pairs. This is the key to the stability of this profile. Also, other neighbor cores (within CCX) can "share" voltages.

Very nice! Good alternative to per core curve optimization. My 5800X it's best core is actually the worst. So now I can finally bypass that. I'm very excited to test this new feature En benshmark the gaming performance in sc2.

Hi, great work! I have some questions: - Why isn't CB using all cores? Did u set affinity to only use the fastest cores? - Will it be possible to use PX profile for all core workload so that the fastest cores use 5 Ghz and the other cores something like 4.6-4.8 with excellent cooling which can deal with 300W for a 5950X? - Would a complete manual mode for setting the voltage + frequency for each individual core manually possible?

I have added an additional report to the diagnostic which will tell you which cores are bad and which are good. 3 hit parades according to CPPC , VID and FIT regarding core temperature. The only problem we may encounter is the mislabeling of the cores. Windows is busy distributing the load to the cores based on their CPPC. If your best core is not the best, you will have problems and you will not get the frequency you want. Is it possible to fix CPPC? It is possible. I have yet to find out.

1) CB20 has a setting. I set to use only 3 cores in order to demonstrate to you that everything works flawlessly. That is, we have not only a cool single-core "boost", we have a cool "boos" on 3 cores. 2) Unfortunately, this is not possible. The frequency for all pairs of cores must be identical (if the pairs are in different CCXs - we can have a different frequency for each pair.). All other cores will run at the base frequency of the CCX domain (this frequency is defined as the highest frequency - 1000MHz. That is, for 5025MHz, the CCX domain base frequency is only 4025MHz). Ryzen has no mechanism similar to Intel to control each core individually. We have an emulation of this mode with big limitations. 3) Yes it is possible. When I get access to the CO from Windows I will definitely add this to the CTR.

I love this 3 ~ 6 core boost idea and implementation. It fit the best for game, design works. I always wondering why CPU vendor only give us two choices: ALL core boost or one core boost. In real life, 3 to 6 is the most possible case. Check the games, popular power hungry apps, the sweet spot is just like this one!! Great insight.

Larry Hope

One question: IF we could set a quick & rough CO settings for all core like -5 or -10, usually this is safe. Will this setting makes PX profile's 3 ~ 6 cores run even faster?

A longer process of testing the processor would mean that the product would be very expensive. This is the main reason why we have PBO/PB and the opportunity to realize the hidden potential.

No, it is a manual mode, the coefficients cannot affect it.

My 3950x thanks you for all your hard work. Days upon days of rendering have proven the benefits of your brilliant solution. Heartfelt thank you :)

Gabriel

Cant wait to try this!!!

For Zen 2, you will have to wait a little while. The PX profile will work in beta 2, but the automatic maximum frequency selection will not work for Zen 2. I will implement this within a few weeks. I just need time for research.

When do you expect to get CTR 2.0 to release?

Morgan Ring

My 5600X is a bronze sample, even on P2 it only runs stable at 4550mhz at 1300. Realistically, would my cpu be able to boost any higher on any of the cores with this new PX update?

James Tiller

The 15th is so far off when you read the date then look at the calendar. Waiting patiently on standby.

Michael

Could it be that your tweet regarding the 15th february release of this feature started speculation about AMD releasing 5Ghz zen 3 cpus (see wccftech)?

Riwwelorsch
>>53495112

Apart from the fact that the tweet was really a bit vague, it shows the extremely good editorial performance on the part of wccftech. NOT. Yuri you made it! A tweet from you can have an impact on the stock market price of AMD :-)

>>53491988

Not that far :) AMD has been fixing the monitoring for 3 months. That's a long time :D

Hi! Thank you for your work! I have a general question: Is 5900x better for singe core OC than 5950x? Is 5950x the king cpu or are there reasons to get the lower tiered ones?

Xdrqgol
>>53518687

Ye, I have the same question! Looking forward to your answer Yuri!

Xdrqgol

On another note Yuri, what would you recommend ( bare minimum) as a motherboard for these CPU’s - Ryzen 7 5800x - Ryzen 9 5900x - Ryzen 9 5950x Thanks in advance!

1usmus
>>53528452

I really like MSI B550 Unify, ASUS STRIX B550-E (XE too). The boards have a moderate price tag, but they have impressive VRM capabilities.

KMHTech

So since you seem to be getting into the 5000 series what build and settings are best for 3600x now?

Hey guys how do I join discord?

I've been doing manual CO on my 5800X, and single-threaded Prime95 with FFT size 5000-8192 (5M to 8M) typically takes several hours to fail when the curve is too low. I'm skeptical that CTR will be able to avoid this kind of instability in a reasonable amount of time... unless the instability is coming from PBO/CO itself.

I ve tried many times without success... always ending in BSOD... sometimes i just click TUNE and its a BSOD. 5950x

Xdrqgol
>>53575437

What motherboard are you using for your 5950x? What Bios version? What RAM clocks?

1usmus
>>53570540

Fortunately, you don't have to wait to find the error with prime. There are other metrics that can be used to detect if Curve is stable or unstable. It is very early to talk about it now because the operating system has no access to this function.

5950x , msi godlike , ram 3800 ( tested memtest , fully stbale )

Xdrqgol
>>53613777

have you fixed it with Yuri or still ? If you run the program with the current stable settings, it should run fine - during tuning it will crash at one point, it will restart and be patient and wait until the program fully recovered. Either you do not have the NET framework installed or something is wrong with either you BIOS version or Windows version...

James Tiller

Still on for tomorrow the 15th? Texas is frozen :D so plenty of time to test.

Southern Germany too and another 1 week vacation ... holy shit, that'll be fine :>
