![]() ![]() I made a mistake on purpose and instead of 4525 MHz, I entered 4550 MHz. ![]() If you accidentally make a mistake it will not cause any problems in most cases. That is we have 3 extra steps of 25 mV = 150 MHz. There is a tacit rule for Zen 2 processors, every +25mV to Reference voltage is +50MHz to Reference Frequency. Next, I recalculate the Reference Frequency value relative to the values I received after the diagnosis (Reference voltage 1250 and Reference Frequency 4375). First of all, I'm correcting the Reference voltage value to 1325 mV, which is slightly higher than the maximum safe value for AVX Light mode. Of course, now I need to adjust some values so that CTR allows you to make additional overclocking. I preferred to continue, I want to get even more performance from the processor. Looks good, doesn't it? At this point, the user will have a dilemma to activate the profile (CREATE & APPLY PROFILE) and leave CTR or continue experiments. ![]() When CTR is finished, the user interface will be unlocked and the resulting tuning results will appear in the log.Īlso, if "CB20 testing" was not disabled in the settings, the user will receive an additional report, which will be located on the "BENCHMARK" page. Usually, the tuning process takes about 15 minutes. There is no need to worry, CTR knows what to do. After a while, CTR will detect instability on one (or more) CCX and inform the user about it. Then we will start the step-by-step selection of the stable frequency for each CCX. CTR will start the Cinebench R20 automatically, get the results from it, and close it. After a few "steps" CTR will log a small report and set automatically recommended values for safe overclocking (orange and red ovals).īe patient, the diagnosis may take some time (the number of steps is not a fixed value). This will save the tuning time in the future and will also give us an idea of what kind of sample we have and what it is capable of. Now we need to do a diagnostic of our processor. If the CTR does not see the frequency, Ryzen Master should be reinstalled, and if the kernel tags look incorrect, clear the System log and reboot the system. The windows with frequency should not have "0" and the core tags should not have "100". The next step is to run CTR.exe and evaluate how well the monitoring works. For example, I use a 3200 MHz DRAM frequency. I also advise you not to use serious overclocking DRAM, because CTR cannot distinguish the problem of voltage shortages on cores from unstable DRAM. Then we made sure that the Voltage CPU and Multiplier CPU were in the "Auto" mode. The first step in the UEFI (BIOS) was to set up VRM: In fact, let's begin the smart overclocking on ASUS ROG Crosshair VIII Hero and the new Ryzen 9 3900XT. Fortunately, CTR will not leave the owners of budget systems behind and will provide additional performance with the same power consumption. Tweet An example of system overclocking and resultsĪs we found out earlier, the results of system tuning with CTR are influenced by the motherboard, "luck" of the sample processor, and the cooling system used. ![]()
