If anyone is interested here are some answers from the 9900x italian guy. Full answer on YT. The tests were done with 2:1 but he managed to boot into windows with 3600uclk 2400IF.
Is 3600 uclk real with proper tunning ? (i dont own zen4 does it even turn on with 3600uclk and 2400IF ?)

@Hail The Brain Slug Quick question does zen4 even boots to windows with 2400IF 3600uclk ? I talked with the italian guy and he said he run 3600/3600/2400 but it was not stable in stress tests.

Some Bits from Computerbase:

-nobody had review samples, so nobody can tell if the SKUs are really taken back and switched out
-AMD knew about a problem for weeks, so they put 31th as release and tried fixing it until then.
-AMD specifically told the press on AMD Tech day over 2 weeks ago that supply of Ryzen 9 SKUs will be (extremely) tight.
-with these info, Computerbase Editor definitely thinks what AMD said to the Verge isn't the truth.
-However, he doesn't know the real reason

Overall it makes me think my Yield Theory gets increasingly more likely. There must be something different for the big SKUs and the only real difference is higher boost clocks.

HUB talked about this a day or two before the news broke, Steve was waiting for a package with the CPU's but there was radio silence about when it would ship or arrive, and they were quite overdue compared to earlier launches that had a fixed date.

Tight for 9950X only or both 9900X and 9950X?

So paper lunch? Why not delay it another 15-30 days? After all the PR damage is already done after the recall , and if then there are not nearly enough units available for a launch… what’s the point?

The only thing i will say is that i dont use LN2 nor dry ice, runs were done with my large loop watercooling.
GB runs were done with PBO CO + baseclock (not allcore static OC)
Lol, the real burning question is, how'd you get your grubby mitts on one?:p

gustlegga: "When did you receive notice to return the review kit?"
Volker: "We did not have a review kit! Just like everybody else did not have any."

The fact the delay is only two weeks and affects desktop parts only makes me believe there is no hardware problem. Especially with the heat spreader that is one of the easiest things to keep under check (and it is a proven process, especially on desktop parts).
My guess is that either.

- AMD wants to get the BIOSes for older mainboards as polished as they can before the launch. Especially when Intel is releasing a microcode update that might reduce a little their performance, ths making the 9xxx series look better.
- There was a problem with the production testing equipment or testing conditions for the desktop parts that was detected late, that could have caused some unstable CPUs to be passed as good ones. Testing is not an easy task, especially on complex and power hungry devices as CPUs are nowadays.

Is 3600uclk and 2400fclk possible or is the italian guy delusional ?

You'd think they'd want the higher end parts to get media coverage first. But they may not have a choice in this situation.

5.95GHz stock would have been possible with N3E thanks to FinFlex. Sucks that desktop won’t get 3nm anytime soon.
Maybe, maybe not. Surface area, power density, and core architecture have a lot to do with it as well. Considering Intels current plight, I think all companies are now very wary of chasing frequencies >2.5x that of microwave ovens.
