News Intel's Arrow Lake performance fix is now available — another update coming next month

So now even CPUs need a zero-day patch...

Ehhh, my X570 platform/Zen3 was pretty flaky running at DDR4/3600 until like 3 BIOS revisions (I bought my 5950X very early), not really that unusual anymore.

Technically, though, 3600 is out of spec for the infinity fabric at the ratio the DOCP sets it on the cpu though, I guess that's not an entirely fair comparison.

So some things I noticed while looking up further information:

1. Intel's post makes it sound like the PPM issue was related to 24H2 as opposed to a general Windows issue (I'm still on 23H2 due to reviewer reports upon launch):
   

   Symptoms: Unusual CPU scheduling behaviors; artificial performance increases when cores are manually disabled or affinitized; high run-to-run variation in benchmarks; reduced single-threaded scores or performance; intermittent DRAM latency spikes (~1.5-2.0x expected); and unexplained performance differences between Windows 11 23H2 and 24H2.

2. It looks like the Intel ME firmware is actually finally being updated with BIOS updates. While looking through Asus, ASRock and Gigabyte BIOS updates they all referred to the BIOS update including IME firmware. Seems like this is the proper solution and one Intel really should have implemented long ago.
3. edit: Asus has the 0x114 microcode and it includes ME 19.0.0.1827 (19.0.0.1854v2.2 or newer is required per the Intel update)

Even if Intel fixes their CPU problems , They need to be punished for releasing beta version of their CPU ... Where were the Testers and the Engineering samples ? what are you doing intel ? did you even BOTHER to test your products before releasing them . NO THANK YOU. you need to be punished.
I hope ALL skip this generation. intel really needs a hard lesson.

Was hoping intel could pull of a miracle with Arrow Lake which they don't even manufacture, and still effd it up. Bought 9800X3D, it has been out of the box stable and insanely fast, what a role reversal for AMD, to replace my 13700K. Intel lost a lifelong customer.

Sounds like intel had someone on the inside screwing things up intentionally if the upto 30% is true.
