    Asus ROG Ally - Super IO Chip replacement

    Hello everyone,
    anyone here who has experience with replacing the super IO chip of an ROG ally?
    I have one on my bench which has a burnt super io (ITE 5125VG-192). On some devices the super-io downloads it's firmware from BIOS if it's empty. As i don't have a programmer for this chips i hope someone here has already changed the chip and can give me a hint if it's working with an empty chip if it needs external programming.
    Thanks

      a small update: I ordered a new, pressumably empty EC chip. After desoldering the old one, the problem (1.8ohm short on a cap near ec chip and 3.3v ldo line only providing 2.7V) went away. so I'm pretty confident that the old ec chip was burnt and was the problem.
      however, after soldering the new ec chip nothing happens. meter shows solid 20V with 0A current consumption. On the board, only the 3.3V ldo seems to be active, with a derived 1.8V for powering the Bios. Coils look fine ohms-wise, no suspicios shorts.
      any ideas where to look next?

          Yes, i've replaced IT5125VG on asus ROG motherboard and it doesnt needs programming. It will program itself orst power on. Soldering this type of SIO requires good skill.A slightly higher temp on hot air gun may damage the SIO.
          Aligning it perfectly on the mb is another challenge. Are you sure you soldered it correctly and no pcb trace was damaged during cleaning?

              Thanks for the heads-up mcpisig123. I hadn't had a problem with soldering BGAs for ages but i took your advise serious. just desoldered, reballed and re-soldered the ec-chip but still no change of problem. Maybe i really am unlucky with the chip itself, that would be a bummer :-( I decided to check the bios, maybe it got faulty by the same fault that destroyed the original ec chip. I just read it and will ask the forum to check it as I have no clue what to look for when it comes to bios
              keep you posted

                  Was the SIO chip sourced from reliable vendor? A lot of fake chips has flooded the market.

                      bought it from ali express from a vendor i bought a lot of stuff from the last month/year, so I'd say it's as good as it gets

                          Asus laptop EC/SIO chip replacement
                          by ebugs
                          Asus Vivobook 15 (board X513ea R2.0) gone dead when user plugged an iPhone cable into the USB-C port during boot. Now there's no LED light, no power at all. I checked all MOSFETs and capacitors, no shorts found. The board only has 3.3V and 5V present, no other voltages.

                          I injected 3.3V into the EC chip power rail (ITE IT5125VG 128), and it draws 80mA, while the 3.3V LDO chip RT8249C has a max output of 100mA. I checked the boardview and found there are only two chips on this 3.3V rail, EC and Realtek audio chip. So I think EC could be the problem.

                          I found the EC chip...

                          Asus Chromebox CN62 - wrong chip put on BIOS reader
                          by BMCappelletti
                          Long story short:
                          - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
                          - gave the computer to his son a couple years later
                          - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
                          - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
                          (seems like the story was not that short)

                          He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

                          Asus ROG Ally X -RC72LA - changed hidden bios settings with 'Smokeless-UMAF', won't get past boot logo
                          by throwaway327
                          ASUS ROG Ally X - (Handheld Gaming PC)
                          Model No: RC72LA
                          Serial No: SBNVKD001014459

                          Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

                          I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

                          Problem Flashing Macronix MX25L6445E BIOS Chip with CH341A and EZP2019+ on ASUS X455LD
                          by pengamat_hebat
                          Hello everyone,

                          I'm trying to flash the BIOS chip Macronix MX25L6445E from my ASUS X455LD laptop using both a CH341A and an EZP2019+ programmer, but I keep encountering issues.

                          Reading the chip works perfectly, and I can extract the BIOS dump without any problems.

                          However, erasing and writing fail every time, regardless of the software I use. (Neo, asprog, ch341, etc)

                          I also tried applying 3.3V to pin 3, but it still didn't work.

                          I attempted to unprotect the chip, but when I read it back, the registers remained unchanged.
                          ...
