Review on 32GB Memory Upgrade Kit For Laptops: Timetec DDR4 2666MHz PC4-21300 Non-ECC Unbuffered RAM Modules (2X16GB) With 2Rx8 Dual Rank And 260 Pin SODIMM Design, Ideal For Notebook PC And Computer Upgrades by Byron Howell

I upgraded my 2018 Mac Mini's memory last night using this product. Everything went well (although it was needlessly complicated and delicate), but the system would not POST. While disassembling the system to debug the issue, my spudger must have slid under the fan socket and broke off a large portion of the socket. Five of the six pins were still in place. I tried to bend the sixth pin down, but it fell off as soon as I touched it. I was able to get the system to boot with the original 8GiB, so I replaced the 32GiB and it now booted. The SO-DIMMs are enshrouded in an EMI shield and have rubber bumpers to prevent shorting with the shield. The rubber bumpers are tricky to slide into place and the SO-DIMM retention levers are very touchy; if you breathe on them wrong the SO-DIMM will pop out. My assumption is that the original failure was caused by one of the SO-DIMMs releasing while I put on either the rubber bumpers or the EMI shield. In any case, do not fully assemble your mac mini until you test that your system will boot after sliding the motherboard into the case and connecting the PSU.My mac mini has been stable since the upgrade. Despite losing nearly half of my fan socket and one pin, the fan cable still snapped securely in place and the system performance thermally under controlled loads similarly to intact 2018 mac minis documented on the web.Although several videos that I watched recommended using a spudger to pry off the fan cable, I later found that ifixit recommended gently pulling the cable straight up using no tools. I wish I had seen that first. Do not use a spudger on any of the cables unless necessary and when you do, make sure it is nowhere near the socket.Here's the toolkit that I used and recommend:https://smile.amazon.com/gp/product/B07GWS5G3R/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1
