Hi.
System: 9800X3D, 8 cores / 16 logical (reported), PBO +200 with -21mV setup (hits 5425 MHz); ASUS X870e ROG Strix-E motherboard (bios 1701). Using Corsair AIB liquid cooler with pump/fans set to extreme. 64 GB (2x32GB) of Corsair 6000 MT with 30/36/36/76 reported and set (XMP II).
CPU-Z single thread: 757 and multithread: 8212 — AMD Ryzen 7 9800X3D @ 5422.65 MHz – CPU-Z VALIDATOR
I also get a low CPU score on 3dmark Timespy with ~13400 or so. CPU Max temp of 82C hit during benchmarks.
I've gone over the PBO settings and memory don't see anything wrong. I'd expect CPU single thread to be ~820 or more, and Timespy CPU to be closer to 16k. It's at least 10% below target. I guess it could be bad silicon lottery, but I'm not sure. SMT is enabled, both checked bios and CPU-Z report. I do have all the windows 11 memory protections and such enabled (core isolation, security processor, secure boot enabled). Game Turbo High performance mode enabled for power mode.
Help!
