I suggested your attempt be posted on “Hackaday” and they did.
There are some good comments, but also some mean ones lol.
Worth a read if anyone else found this interesting.
Edit: Great comments that sheds some light on what may have happened.

Hey! Here from Hackaday, finally found a free moment to reply =)
Good suggestions on unpopulated resistors in this thread! My opinion is that you should try a DDR3 tester like this one: [ item ID 184122198062 on the .com eBay version , silly forum won’t allow links]. Laptop repair techs use these for debugging DDR3 slot connections, and it seems like you’d be able to instantly see - are the usual signals present? I’d recommend you first insert it into the original slot, see how the LEDs look, and then insert it into the new slot - see what the difference is, whether any lines look different… I’m not sure if it’d point out missing terminations/pullups/whatever, but my impression is that it should point out something if your hardware differs - maybe even LEDs glowing at different brightness.
