Cthulhu Build
I recently took apart my Corsair Dominator Platinum RGB 64GB (4x16GB) DDR4 3200 MHz Desktop Memory - Black. I was removing the top bars & LEDs to make the RAM compatible with another CPU cooler (55 mm is too tall).
You need a 1.27 mm Hex wrench. I ordered Tekiro 7 Piece Mini L-Key Short Hex Metric Set to do my set. These worked perfectly. A clear flat surface & a small tray to hold the 8 screws (using 2 of the hex wrenches can be handy, I used the 1.27 mm & the 0.89 mm). 1.5 mm or 0.05" wrenches are too big.
Once the top bars are separated & removed you can use a small flat head screwdriver to separate the PCBs. Top bars are a zinc alloy.
The stamped aluminium heat spreader fins have a small strip of glue, but are easily peeled off. Be careful not to bend. Although I did on 1 out of the 8 pieces & it was easy to reshape & reinstall.
Scrolling up & down this page basically shows you the assembly/disassembly of a RAM stick:
