Really nice vid from tech Jesus, they have truly outdone themselves this time.

What's not so nice is the evasive and misleading responses given by both AMD and the mobo manufacturer to GN, trying to sweep the problem under the carpet and putting the blame on the end-user for their OWN fuckups.

that one is more for self promo and gratification.

The truth is there are many minor issues that AMD have kept it hidden / kept it quiet not just for current 7xxx but also for all the past
zen series and its associated platform.

GN's follow-up on their previous AMD Kaboom video.

So what's da conclusion?

The take away is the same as the first video with more explanation and context.

The core issue isn't the aftermath from using a dead CPU with ASUS board (though still an issue). It's why did the CPU die to begin with and how? If you just have crap luck and ended up with one of the chips with just the right "quality", any board pumping high voltage can degrade it to where there is a dielectric breakdown/short. ASUS problem is that after this happens, the board is asleep at the wheel and keeps pushing the gas pedal. Other boards may have better OCP and cut the power, but the CPU is still going to be dead (as some posts here have shown with dead 7000 series and very slight discoloration in substrate).

GN deduced that it's likely due to high SOC voltage (ASUS boards were likely more notorious at applying higher voltages). What we've seen is that nearly all boards were applying higher voltages. If the degradation has already begun, there is no reversing it. At best, you can halt/slow it down to where the use cycle of CPU will be greater than the degradation.

There is no point in panicking now, you can lower the SOC voltage with updated bios or manually and keep on using the CPU. There isn't really a whole lot else that someone can do if they've been feeding high voltage. Maybe the silicon is a champ and nothing happened, maybe something did, no way to know unless you got some of this equipment laying around to scan your CPU.

Oh, also, the video ends with him calling Asus a scumbag company and that their will be a third part to this series where they discuss Asus being a scumbag company and warranty claims that will be involved etc.

This issue is prevalent on Asus boards.

"This story is mostly done, we have one more piece at least that focuses though on the Bios, the Warranty issues, and Asus being a Massive Scumbag of a Company. But that video is less objectively focused and more focused on some of the more Don't be a scumbag company aspect of it"

Word for word what he said.

To summarized , if u ever ended up with a LOUSY silicon and it can't tolerate the voltage it's being fed into, then this meltdown is more likely to happen.
Seems to justify what i had already guessed earlier. It's not first time. Happens to all Zen Cpu's with crap silicon quality. More likely to inhibit/cause platform instability one way or another.

What's da point in him bashing Asus ?? It's ZEN architecture he shld be commenting on.

Shhh!! Can't bash Zen uarch as this never happen in 1000-3000-5000 series and they have spent too many years praising Zen while hitting Intel. For science sake I'd love to see if someone could replicate this phenomena with a 5800x3d and a Asus mobo.

Permanent damage on CPU & mobo? Note to self; never to buy 7000series + X570/B650/A620 mobos in the used market few years down the road.

How do u know it never happen? Have u used Zen before? Those lower than normal silicon. It may not lead to burnouts but induce other forms of platform instability. I did owned few of those zens in the past and I know how they behave normally and what will happened if the silicon is lousy.

Looks like all parties including Amd are not telling the whole truth regarding the soc voltages.

Betcha the soc will be more than just 1.3v to keep the platform stable when engaging Expo.
