I looked at the forum, if I'm not mistaken you had K5A5 memory for MBP 16 M3 Pro and LB Tool programmer, right?I would go with a variant, you can renew again. I made a mistake before and has written 3 of 4 chips.
Because one was broken. Without the option, to delete them, it’s pretty much money you will waste.
I just checked for resistance <50 ohm. For the „beep“ directly after soldering between 0.9v and GND there will be a beep. Just let it cool down. After 5 min should be >50 ohm that’s fine
