Looking for broken or dead DDR4/5 memory

Hi all, can anyone direct me to where I can buy dead DDR4 ram modules? I recently got into SMD soldering and managed to resurrect a dead stick I had around, figured might be a good way to recycle sticks headed for the landfill. Unfortunately it's only really worth the effort for high capacity sticks so I'm specifically looking for 32GB+ DDR4 sticks 3200 or higher speed. DDR5 too (though I have no way to test those at the moment). Oddly enough I cant find any on ebay. If anyone has some lying around and is willing to donate/sell let me know.
