But I have to say, this thread director and/or Win11, still puts Bitwig on the E-cores if the window/application is not in focus. Play a track in bitwig with the DSP perf graph open, then switch to another app like a browser and use that for a few seconds, you will see in bitwig the performance tanks and audio crackles, because the thread director or win11 decided to put Bitwig on the e-cores. :lol: :clown:

Anyone seen this behavior?

I don't know if this is a Bitwig issue or not. I need to ask them if they are aware of this. But I read others have the same issue with different software...

Meanwhile I had my first bluescreen. W10 gets stuck on welcome screen out of the blue, what an abomination of a system.
And if I run a really heavy Kontakt instrument I get crackles. It feels less and less an upgrade.
You have the ASUS HERO, so do not install ASUS armory crate and in the BIOS try:

- SB Clock Spread Spectrum = Disabled
- Power Supply Idle Control = Typical Current Idle
- VDDCR CPU Switching Frequency = 350 (If the default is higher, keep the default)
- VDDCR CPU Power Phase Control = Extreme
- VDDCR SOC Switching Frequency = 350 (If the default is higher, keep the default)
- VDDCR SOC Power Phase Control = Extreme
When Power Phase Control = Extreme, all VRMs will stay active, they will not
"sleep" even in idle, this generates more VRM heat, but better electric signal.
Because the Hero motherboard has an excellent VRM you do not need to use
EXTREME for the CPU, but should use for the SOC.

- Do not undervolt the CPU.
- Do ALL my tweaks.
- Use Windows 11.
- Try to reseat the CPU.
- Verify if the CPU socket have bent pins.
- Do not overclock the RAM.
- Do not overclock the CPU.

The RAM speed maybe is too much for the memory controller.
The Intel memory controller sometimes is a bitch and hard to detect errors. :(

Test the RAM/memory controller, in your case leave it running 6 hours or more
***ONLY*** the y-cruncher tests 17/18/19/20.
The other tests will "fry" the CPU! You should not do the other tests for hours and
hours, but can do for minutes.

The CPU may be defective. :(

There's nothing wrong or sub-par with the i9 13900k or 14900k.
Yes, they draw a lot of power.
Yes, they require top-tier 480mm AIO cooling.
I guess you will build more AM5 now.
Current AM5 users can upgrade by only replacing the CPU.

Intel's 13900k's and 14900k's are crashing at an alarming rate?

Yeah. Not good. Chips appear to start out ok but "degrade" over time. It's also looking like the earlier "motherboards running chips out of spec" problem might've been a bit of a red herring, and actually alluded to this wider problem (The failures are also being seen on server boards which have never ran at the higher voltages.. )

Wendell (of L1) estimates that, conservatively, Intel might have to end up replacing at least 25% of the CPU's - and even that assumes they provide updates which can mitigate the problem for others. Apparently Gamers Nexus also think they have an idea of what the issue is, so I guess we can expect to see some more videos on this soon.

At this point people shouldn't build systems based on the 13900 / 14900. If you do expect instability which increases over time, and which may be made worse by other factors like higher DDR speeds. I assume Intel will do the right thing, and replace any chips which can be shown to have problems. The longer you have run the chip, the more likely that is to be true.

I did a bit of gaming. And yep I have crashes. Early to draw conclusions, as it's just one game, but it's like random crash every 2 hours. Initially I blamed overheating GPU, but nope. Eventually I did what the guy in second video said they did (so it resonated for me), reduced memory clock. Again, too early to say, but for a first time it didn't crash.

RMA the CPU.

Nah. Too much trouble, it would have to get seriously bad. One game crashing is not nearly close to the threshold of RMA, especially considering swapping CPU may not help. Changed memory clock from 6400 to 6200, changed XMP profile from II to I, no crashes since.

Intel is in breaking point situation IMO. Either they will do something bold, or they go down. If I was to bet, I would say they will do nothing and eventually they will fall down to third position in CPU manufacturing. Sadly.

In another video there was a suggestion it's all due to moving I/O hub to separate section of CPU. So possibly a fundamental design flaw.
