Hi! So i replaced the HDD with a Samsung 860 EVO 1Tb SSD and 2x8gb (16gb total) Kingston HyperX 204-Pin DDR3 SO-DIMM DDR3L 1600MHz memory. The laptop is a Macbook Pro 15” mid 2012 I have had the three beep problem before (tells u theres a problem with ram) but removed one of the original rams and seemed to work, this was a while back. Now that ive updated it, it randomly freezes or crashes with strange pattern and static on the screen. Sometimes it turns off on its own and sometimes it just freezes so i force turn off. When I try to turn it back on the three beeps again. After a while of being off it turns back on as normal. Also when its sleeping for some time and i open the lid the sounds from when u restart it happen but it doesnt really restart only the enter password screen appears. But internaly u hear as if i have restarted it or turned it on. As i was writting this on my phone the mbp just turned off and the beeps again no crash this time… I think its obviouly a ram problem and not an ssd one. But is it a faulty ram? Or maybe where u insert the ram? Or did i buy the wrong type of ram? It very frustrating since i updated the components for the computer to last me some more years as i cant afford a new one. And i also have some battery problems so having a new components problem is very frustrating. Thanks in advance and sorry for bad english
Are you sure you purchased the correct memory for your laptop? If so, maybe the memory you bought is defective. I bought some memory once from Ebay. It appeared to be the correct memory; but the computer wouldn’t boot all the way after I installed it. Turns out the memory was for an AMD machine, and my machine was Intel. After the seller told me that, I looked back at the product description, and sure enough, it said that it was for AMD machines!
