    sse4.1 issue with harpertown xeon lga775 mod

    i ordered a modded lga775 xeon x5470 from china and it arrived last week and i only got to testing it yesterday. i put the cpu in my gigabyte ep35-ds3r motherboard whose chipset can support the cpu.

    however, when i fired up cpu-z to check the cpu specs, i noticed that sse4.1 was missing from the list of instructions on the cpu. i attached an image of the problem. i checked wikipedia and it says the harpertown xeons do support sse4.1.

    so i wanna ask if this is just a cpu-z display problem or is it a bios/os/microcode issue of using modded lga771 cpus in an lga775 board? thanks.

      You need to update the microcode https://www.delidded.com/how-to-upda...-bios/#method1

          MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
          by rounin
          Hi everyone,

          I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

          🛠 Original Issue
          The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
          Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

          I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

          ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

          Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
          by ugamazing
          I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

          We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...
