Review: good for the price - compared to all the other options the price was very good, the memory worked correct in my 2018 mac mini I3 quad core. I will say this that installing in these mac minis is not easy and you should watch a video how to install. The minni runs faster now and gets things done the way I want now.
Review: Works for my HP 440 G3 ProBook - My HP ProBook 440 G3 specs say the RAM is limited to 8GB (DDR4) x 2 slots for a max of 16GB. I made sure the laptop's firmware (BIOS) was up to date and tried one of these. It recognizes a single 32GB module without any hiccups. On first boot, the laptop came up with a message that there was a memory change, I went into the BIOS, confirmed the change and viola! It works. To see if the memory would go even higher, I mixed this 32GB with one of the old 8GB modules and that worked as well. At this price it's worth it for me to max this thing out at 64GB.

### ⭐⭐⭐⭐⭐ Works for my HP 440 G3 ProBook
*by L***B on February 2, 2022*

My HP ProBook 440 G3 specs say the RAM is limited to 8GB (DDR4) x 2 slots for a max of 16GB. I made sure the laptop's firmware (BIOS) was up to date and tried one of these.

### ⭐⭐⭐⭐⭐ New life for my 2019 imac
*by B***R on August 18, 2025*

My 2019 imac had become unbearably slow, taking forever to "warm up" and becoming useable after being in sleep mode. Also loading Chrome pages very slowly and continuously "beach balling" . The Activity Monitor showed only 8GB of RAM installed and Used Memory was always upwards of 7GB. Installed this in about 5 minutes and I had a dramatic increase in performance. Used Memory is now in the 20GB range so 64GB may have been overkill but for the price I like knowing the extra capacity is there. As others mentioned the initial reboot after installing these takes awhile and I had to reboot a couple times before things settled in, Overall very happy with this purchase as it looks like I can get a couple more years out of my imac. Only minor negative was shipping time but guess we are all spoiled by the "get it tomorrow" mindset.
