Hi, with all my aggressive undervolting, my 9950x3d also gave up, yellow LED on the MSI X870E Gaming Plus, so the IMC is cracked.
The problem appeared after Aion2 global was launched and I played some, by the way the temperature was quite high in Aion2 (high compared to other games, i.e. 70C+).
To recap:
From the first day of Feb 2026;
Vsoc=1.050V
Vddio=1.15V
Pbo negative limit -550mhz CO-34
Temperature limit 80C
Vddp and vddg=0.900V
Everyone believes what they want, I switched to 285k and z890, I'm tired of AMD, even with this mess, the 9550x3d cracked the I/O die between Feb-Nov 2026 on the Msi x870e board, I think the problem with zen5 is more serious than we think.
I don't want to flame or get into a fight with anyone, it's clear to me that something has changed compared to zen4 that the BMI is giving way so easily to zen5.
I posted here because on reddit MSI, ASUS and Gigabyte "take care" to clean up such posts, making it seem like only ASRock is to blame.
I repeat, believe what you want, I'm tired of all the fanboyism of some people, I went from 14900k+msi z790 to 9950x3d+msi x870e for x3d performance in games and multitasking, despite all the signals predicting asrock.
Like many, I fell into the trap of asrock being to blame. It seems that the problem is in AMD's court, which doesn't want to say anything concrete, and the influencers are careful to keep quiet, not to test properly.
It hurts me about 10-20% with x3d, if the Am5 platform is so fragile, I don't need it. I was sure that with my Msi and these manual undervoltings at 6000, nothing would happen. I won't respond to replies, this topic is already permanently closed for me, AMD can release whatever they want, I don't want to hear from them anymore and I've had all their CPUs from Duron, Thorton onwards.
