    My i7- 4790K from 2014 thanks you.

      4790k brother!

        I still have my 4790k too!

        I swear basically everyone that bought one just never got rid of it.

        Even now I’m thinking “I may need an upgrade… in a couple years”

      I have a 4770k that’s happily chugging along. It’s the only windows machine left in the house. I’m not the one using it but it’s a fine machine (it used to run linux before I had to downgrade it to pass it along to my SO).

      It doesn’t get to run any games though. I’ll have to see if it’s worth it to mess with it.

        The only game I’m having stutters in is Escape From Tarkov (CPU intensive, and optimized for single-core).

        Other than that, It runs everything I throw at it without a flinch.

    I’d like to see some benchmarks to know if it made any measurable difference.

    Somehow I doubt that manufacturers of 13 years old motherboards are going to update their UEFIs… I would love to be proven wrong, but it was hard enough to find a UEFI able to POST on a 2080 super already.

      That’s exactly why this project exists, to allow users to add ReBAR support to their old motherboards.

        Thanks 🙏

      I’m running up against the wall of breaking the signature. I guess my motherboard protects itself from unsigned modifications and idiot tinkerers 😂

        You might be able to drop the manufacturer’s keys somehow[^1] but I would not recommend.

        If you really want to do this, I would recommend:

        1. Unsoldering the eeprom
        2. Soldering a slot in socket instead
        3. Getting a new blank chip
        4. Getting an eeprom programmer
        5. Dumping the eeprom to a bin file
        6. Flashing that bin file onto the new eeprom
        7. Testing that the motherboard POSTs
        8. Searching for cryptographic signatures (possibly compressed, possibly obfuscated - rolling XOR, reversed, etc) in the bin file
        9. Hacking around that bin file trying to blank the keys, or better yet, replace them with yours.
        10. Go to step 7, repeat.

        Of course, you could always flash the modified bin onto the new eeprom directly at step 6, but what’s the fun in that? 😅

        Also, if you really do this(!), please don’t forget to document. 🙏

        [^1]: I doubt they went as far as “fusing” them in the factory, it would be perceived as “overkill” for a general public product - which I assume it is - and would risk running the risk of bricking upgradibility of the board, should the manufacturer lose the keys. Plus, it doesn’t help anything (quite the contrary) if the keys are somehow leaked by the manufacturer.

    Now I’m a bit out of the loop with this.

    Would there be any benefit for a 8700k paired with a 1080ti?

      In order to use the resizable BAR feature.you need a compatible CPU and GPU. This would make it possible to use older CPUs but you’ll still need a compatible GPU which I think it’s series 2000 and newer for nVidia, so no.

        Hmm, I’ve got a 3080 in my i7 5930K system. I wonder if it works on that?

    If only I had access to a windows machine to patch my old ass motherboard 🥹🫡

      I haven’t completed read through the tutorial, but UEFITool does exist for Linux. (I had unsuccessfully added NVMe support to an old motherboard previously)

        Managed to get it working with wine. But now I am running up against issues with my motherboard and failing the security verification of the modified bios 😅

        Stay tuned… 🤓

        I tried it out with my Linux box. There’s a step that requires MMtools that I can’t run with out windows unfortunately 🥲

      use a winPE boot image?

      • quaff@lemmy.ca ⁨9⁩ ⁨months⁩ ago

        Whoa. I didn’t know this was a thing! Windows live CD! That’s awesome. Thank you for this! I managed to get MMtools working with wine. But definitely gonna try a few things with this since I’m getting some security verification failures with the modified bios 👀

    Sandy Bridge was such a monster when it dropped. Weird to see it in this context. shakes cane

    This is common on the cheap X79 and X99 motherboard combos being sold in aliexpress, they even add nvme support.
