This means that CTR could not access the processor. Because there is software that blocks it or does not properly communicate with the processor. In this case simply restart system with CTR or eliminate the culprit. P.s. don't forget to uninstall the previous version of the program.

I have 0 program launched. Just brand new W10 + CTR RC4. RC3 was working and is still working though (even if all profiles and settings of RC3 have been erased without a single prompt from CTR RC4).

How do you uninstall a zip file which has no installation?

use the config cleaner: https://www.guru3d.com/files-get/clocktuner-for-ryzen-download,3.html

Getting less frequency than RC3 and the results page is confusing with better performance shown for CB testing but less overall compared to the default system specs...

Tried it, same issue, RC4 won't start (while RC3's working like a charm).

@guilamu, try deleting everything from rc3 then copy over new files. Run the config remover then reboot your pc. Should work?

No luck. I've got a pretty standard rig, so I guess most people won't be able to use RC4.

I'm scared by comments above... I'm using RC3 and it is working just fine. What is the safest mode to upgrade to RC4 ?

RC4 worked very well for me. The best version so far for me. What does Boost Tester do?

That's really interesting : It doesn't work for me neither. I launched it with administrator privileges. I closed MSI Afterburner and Corsair iCUE. I deziped it on another folder than the previous version. ***ClockTuner for Ryzen 2.1 RC1 by 1usmus*** AMD Ryzen 7 3800X 8-Core Processor ASUS ROG STRIX X570-E GAMING BIOS ver. 3405 SMU ver. 00.00.00 DRAM speed 3600 MHz 03/04/2021 23:04:31 23:04:32: CMD_REJECTED_BUSY 6 PMTable read failed!

I let the bios do mine. honestly dont see the need to use this app. https://valid.x86.fr/bench/q6zhlq/1

Same problem here with the RC4 (X570 and Zen 3)

Of course BIOS work pretty well, but this app permit (when it work lol) to found a little extra to this OC. So yes it's for fun most of the time.

Hi, I resolve the problem of: CMD_REJECTED_BUSY 6 PMTable read failed! 1.- Run the config Cleaner: https://www.guru3d.com/files-get/clocktuner-for-ryzen-download,3.html 2.- Open CTR 2.0 RC3 and check all the config has been erased and close it. 3.- Restart the PC 4.- Open CTR 2.0 RC4. Enjoy. Ps. I dont delete the CTR 2.0 RC3 folder, actually i have the two versions in the same directory but in separate folders.

Is it compatible with TRX40?

1umus a quick question; I have a 3900x silver sample very good cooling 2x 360mm rads, good gigabyte Mobo CTR R2 best CCX = 4525mhz @ 1.325v guessing this was because we were advised to use Turbo LLC very very low v droop CTR R3 best CCX = 4400mhz @ 1.325v auto LLC 3.4% v droop ( tried with turbo before had had warning messages saying it can damage the chip......) CTR R4 best CCX = 4375mhz @ 1.350 auto LLC All fan profiles the same no concerabable temperature difference. Any reason why the frequency goes down and the voltage up in R4 ? I was expecting to get 4450. Many thanks for your program

so you have the only motherboard on the planet capable of hybrid OC. OR you don't know what you are speaking about 😎

i could not get rc4 to work properly. i did stop RC3, removed launch with os. used the tool to reset configuration. i as able to get it through analyzes a couple of times (also experienced reboots) but as soon as i start tuning it either straight restarts, bsod or freezes. i tried countless times even lowering max frequency to 4300 from 4900. it would still start testing at higher values which makes it crash. after restarted it would try immediately to launch cinebench which wold lead to another restart and config datacoruption. it finished once with a score of 7500 when it normally is around 7100 and 7300 for p2. Phoenix - hello there 🙂 CTR completed profile creation in alternative mode Last step was: CCX1 4375 MHz VID 1250 mV CCX2 4375 MHz VID 1250 mV CCX3 4300 MHz VID 1250 mV CCX4 4300 MHz VID 1250 mV Manual overclocking mode enabled Penalties for the final profile: level 3 11:31:59: CCX1 (156): 4275 MHz, 1256 mV OC+ 11:31:59: CCX2 (145): 4275 MHz, 1256 mV OC+ 11:31:59: CCX3 (134): 4200 MHz, 1256 mV OC+ 11:31:59: CCX4 (122): 4200 MHz, 1256 mV OC+ Phoenix deactivated! Cinebench R20 started Cinebench R20 finished with result: 7585 Voltage: 1.256 V PPT: 128.2 W Temperature: 63.8° after numerous crashes i decided to stop because i don't want to break windows which hates crashes. I'm now testing with the values i got from rc3 and sofar seems to run fine so its seems I'm just unable to use tuning in RC4 https://i.imgur.com/LIQv8AI.png

Fun fact! If you have the Corsair iCUE software installed and get sh*tty results, simply uninstall it. It does magic! I went from Bronze sample (no OC) to Silver sample with +200 OC & undervolting. https://forums.guru3d.com/attachments/ctr2-icue-gif.4524/
