Looking at the name, it's not hard to guess that the point is to revive where everything seemed to be already lost. The next innovation in today's hit parade is the new PHOENIX mode. It looks impressive, doesn't it? Anyway, it's up to you to judge. The actual Cinebench R20 performance has grown from 4289 to 4616 (+8%) for 12 threads and from 2842 to 3144 (+10%) for 6 threads, leaving the single-thread performance unchanged. I managed to gain 200 MHz for all-thread load, and for 6-thread, I got around 200 MHz with the same power consumption. Also, in this picture, I see P1 and P2 profiles, which I got during troubleshooting and tuning. In this picture, the standard boost frequency is marked in red relative to the number of cores used. Theory in theory, but let's look at an example of Ryzen 5 5600X with CTR HYBRID OC. It also allows the cores to be kept in a deep sleep (C6) mode while the system is idle. This allows CTR to be unaffected by single-threaded boost, latency measurements, and other benchmarks. At this moment, the graphical shell update is disabled, but all processes remain active. Regarding the CTR background activity, there are also many important changes, and the most important is the CTR sleep mode, when it is in the tray or in a minimized state. I find this value to be quite adequate so that the CTR program's background activity does not overload the system. That is, CTR checks the system status 4 times per second before acting. The temperature interrupt time is 45 seconds, and only after 45 seconds, CTR will decide again which profile to activate or not.Īnother important parameter is the load response of CTR HYBRID OC. So CTR will not let you fry the system even if you really want to. This "cushion" also has its own boss, which can turn off P1 or P2, and its name is Max temperature. In layman's terms, Holding time is a cushion that muffles short-term load spikes. Secondly, the more often CTR interferes with applications, the more context switches are made, which also affects the final performance. If you have a pulsating load, CTR will have to jerk profiles back and forth, and you will lose performance by switching between P0 and P1 or P0 and P2, causing a short-term transient state where you keep the CPU running at 3500-3800MHz at 1.1V. And how is it useful?įirst of all, profile hold times can be 20 milliseconds (estimate for 32 core Threadripper). Holding time is time profile will be kept active even if current CPU or CCX load has changed. In order not to jerk the profile back and forth hundreds of times per minute, a parameter called Holding time is used. That is, the P1 profile has the highest priority and can override the P2 profile at any time if needed. If the P2 profile is used while an application is running, but the CTR detects a CCX usage max boundary-crossing, the P1 profile will automatically be activated in order to keep maximum system stability. Another interesting feature of CTR HYBRID OC is the prioritization of profiles and holding the profile active for a certain time interval. ![]()
