  1. Perfect timing, just booted up a 13700K yesterday, MSI tomahawk, arctic 360, seeing roughly the same 'auto' performance/heat as you. And so I have a question, never messed with my CPU before(oc/undervolt). 3 takeaways from the video, set cpu core voltage to 1.3, loadline calibration to mode 5, and set BCLK 100mhz lock on to enabled. Do that, reboot, retest and cross my fingers. Do I understand those changes correct? I have a clear CMOS button on back so not too worried, but just wanted to be sure. Thanks for any input!

  2. Man. I'm thinking about getting this exact MB and CPU. Dealing with these temps would have been stress for me lol. I'm in various programs all day including blender and other 3D modeling programs because I make mods for games.

  3. Hi Leo,

    I bought this motherboard after reading your review and applied the same settings for my i9 13900KF. Works like a charm.
    I also bought the Gigabyte Z790 Aorus Pro X with an i9 13900KF for my son & I am trying to replicate the settings in the Gigabyte BIOS. I can set the Vcore to 1.300 and adjust the LLC, but I cannot find the 'BCLK 100MHz Lock On' option in that Bios. I know you recently reviewed the Aorus board, can you please recommend on what I should do ?

    Thanks !

  4. Hey there,

    Thanks for the detailed review of the MSI MPG Z790 Carbon Wi-Fi motherboard. It's great to see the in-depth analysis of its performance and features. I appreciate your thoroughness in testing and providing both pros and cons.

    It's concerning to hear about the BIOS issues and excessive power delivery to the CPU. That's definitely something MSI needs to address in future updates. The multiple SSD installation and Wi-Fi 6E support are definite pluses, though.

    Your conclusion is fair and balanced, and I agree that if MSI can fix the BIOS issues, it would be a strong contender in the motherboard market.

    Keep up the good work with your reviews, and I look forward to hearing more from you in the future!

  6. Will these same settings apply to the 17 1400k? As my current board is faulty and the only replacement i can get at the moment is this carbon board. Thank you

  8. Hi! Great reviews, thanks. I have a question reg. trhe M2 slot 1 and slot 2. I will use gen 4 nvme dis, whick slot will be most optimal to use ? I want to use one that is connected directly to CPU without interferring with VGA PCI slot… By the way, I can't find the block diagram for this mainboard, anyone does know where to get it ?

  11. Hi Leo, can you please do an undervolt guide for the i9-13900KS with the MSI Z790 MEG motherboards (ACE or Godlike) ?

    Thanks so much in advance!!

  12. Hmm… tried your settings with an i9 13900KS with Carbon, but no change in temperature. Still zooming to 100° C. But came here looking for how to enable undervolting so Intel XTU will work… where is that setting in bios?

  14. Hey. I have just built a pc using this board.
    Everythings running mega cool and lovely. But for some reason the temperature that reads as system in msi center and just as system in the bios hardware monitor was saying it was 100c! After gaming for a while. But cpu and gpu were only 40 to 50c and nothing on the motherboard was physically hot at all.

    I am having trouble finding out what the temperature under the title system actually relates to. Do you have any ideas?

    I remenbered this video when I saw it and thought maybe its them overkill vrams so I have just manually set my 13th gen i7 to the settings you said to use here and will see if it does it again.

    But any ideas? It is very strange. Maybe a senson just went barmy.

  15. Bought this Board came DOA, IO on the back would light up but the board would not post tried jumping the board (by touching the power pins with a screw driver) nothing would happen. Sucks it was the motherboard in mind for my build, Planned to return and try another one if I don't find a better option(any recommendations would greatly be appreciated).

  17. I just bought an MSI Z790 Carbon Wifi + i9-13900K + Gigabyte AORUS WATERFORCE X 360 + G.Skill Trident Z5 64GB DDR5 6400 CL32-39-39-102 1.40V + MSI GeForce RTX 4080.

    I also made sure to update the BIOS to the latest version, which is 7D89v18 released on September 14, 2023.

    I followed your instructions meticulously, activating XMP, setting the CPU Cooler Tuning to Water Cooler, configuring the CPU Core Voltage to 1.3, enabling CPU Loadline Calibration Control in Mode 5, and locking the BCLK at 100MHz. However, when I ran Cinebench R23.200, I noticed that the CPU temperature consistently reached a worrisome 100°C.

    I experimented with various CPU Core Voltages such as 1.2, 1.25, and 1.36, but the temperature remained stubbornly at 100°C during Cinebench runs. I also tried different Loadline Calibration Control modes, including 1, 3, 4, 5, and 8, but none of them made a difference in the temperature. It consistently stayed at 100°C.
    On the bright side, when the system is idle, the CPU temperature hovers around a comfortable 33°C.

    I'd appreciate any advice or suggestions…

  20. Have these BIOS issues been fixed as of release 7D89v17? I'm sick of the headaches with my ASUS ROG Strix Z790-E, have never had an issue with MSI, but don't want to jump from the frying pan into the fire….

  21. Thank you so much for sharing this video with us. I have the same problem, the computer which I bought 2 weeks ago is still sitting at the market because of overheating. I'm not understanding clearly video because my English is not good. If I make these 3 settings from the bios as you said, the temperature drops as you say and the performance increases, right? I would be very grateful if you could take the time to reply
