Guys, just FYI.
I have two Katanas. I have got exact same problem with Katana GF66 11UC-212FR. I have RMA-d it, as I still had warranty.
Now, 1 year later, EXACT same problem with the second laptop (less used maybe). And now a ton of BS started from MSI Service.
"Have you tried to turn it of/on again?", "Have you tried to F3 reinstall Windows", "Here is the BIOS, just change it (sending E1582IMS.315 dated 06/07/2023)".
A perfect citation is: "ce n'est pas un problème de PC, mais un logiciel qui doit être mis à jour. Il s'agit du BIOS." (Not a material problem, but BIOS).
THAT is the answer of a service engineer from MSI France (or Poland) with 09 years experience as boasted by him at Linkedin.
Yes, this IS the material problem. Yes, I have already put the GPU BIOS (not usual BIOS) from the previosly repaired laptop, thinkng it has been the GPU BIOS problem.
The temporary solution is to put an ACER GPU BIOS, but choose wisely and pay attention, it could run hotter.
It is unbelievable, but it took a MONTH to finally agree with me and send me another RMA. Only after my call to my juriste who explained how to proceed.
MSI FRANCE has sent me three different RMAs, and the last, 4th with an adress in POLAND. No, thank you. With that degree of competence, I'd better stay in France.
So, guys, where to look: HWINFO64 and FurMark (2.6.0 - I used). Run benchmarking on Furmark and check HWINFO. If you see 210Mhz all the time and 752W power consumption, IT IS NOT A DRIVER/BIOS. Repair it as soon as possible.
MSI, you have highly incompetent Service and you are lucky we are not in US. It is a common problem for Katanas, worth a recall. But who really cares, right?
I have never regretted that much any laptop as MSI. Worst, I'm stuck with TWO of them...
PS. About drivers. Writing these lines from a Katana with Nvidia 31.0.15.2824 driver. No problem. I could attach a screenshot, but just believe me, everything is fine... since repairs.
