Glad I could help! If you have any questions or run into any issues, just let me know and I’ll do my best to help.

Go into XTU and set the Core Voltage Offset to -0.120V, then set all cores to 4.8GHz and test it. Your CPU performance should improve significantly. If it’s stable, try lowering it further to -0.125V and test again. The CPU should stop throttling, and temperatures should drop as well. Your CPU score is terrible. You should be getting somewhere between 10,200 and 10,400 points. On my 9900K, I was completely stable at -0.140V with all cores running at 4.8GHz, and I had absolutely no throttling.

To test stability, you can use a memory testing tool or just launch a game and see if the system remains stable.

Is the system stable now? Did you also apply the Memory Warm Test option? With the right timing configuration, you should be able to run stable even at CL19. For now, reboot the system, set those three values I marked to 13, and test it.

I can help you undervolt it without using XTU. You just need to extract the PE32 file and send it to me. If you have any issues, just let me know and I’ll help you out.

0xB43 = 00 disable memory warm boot test Try testing these CL22 settings too.

The timings don’t seem to be compatible with your RAM. What timings are you currently testing with?

Make the changes I mentioned. I’ve marked them in yellow — change those values from 12 to 13. If it’s still not stable, try 14 and let me know. Also, send me a picture of your RAM timings after making the changes.

We need to increase the timings to make the system more stable, because your RAM’s standard timings at 2666 MHz are CL18. If we set them to CL19, it should be more stable.

One of your RAM sticks supports XMP and has good timings, but the other two are pretty bad. The ideal setup is to have matching RAM modules with the same timings and frequency.

Change the ones I marked in yellow to 13.

The timings need to be set manually. If the system doesn’t display an image with these timings, we’ll increase them because two of your RAM sticks are already running at CL18 timings at 2666 MHz. Because of that, we may need to set the timings to CL19 or even CL20. There’s absolutely nothing to worry about, and these settings are completely safe. If you have any questions, feel free to send me a message and I’ll help you through it.

093F is the memory multiplier. When you set it to 0B, the RAM frequency changes to 2933 MHz. The 0940 row contains the memory timings, which are the ones I marked with the red lines.

Besides those three, change the ones I marked with the red lines as well, similar to the picture I sent.

Besides those three, change the ones I marked with the red lines as well, similar to the picture I sent. If the system doesn’t display an image after applying the settings, wait for about 2 minutes and don’t turn it off. It should reboot automatically and display an image again. Then go into the BIOS; the memory frequency will have dropped to 2666 MHz. At that point, I’ll send you more conservative timings so you can reach 2933 MHz.
