The memories are the same (exactly the same model and manufacturer?) If not, are you sure you put them in pairs? Unfortunately, RAM has it that they are from another company, even though they have the same parameters, they will bite and sprinkle with errors if they are not inserted in pairs according to the manufacturer. I had a case that I had GoodRAM dice and I added Kingston, and despite the fact that they had the same timings, the computer was throwing with bsods as the remembered one and in one day I was able to have 10-12 reboots by BSOD. In the end, I managed to figure out what was going on, namely, it turned out that my memories were incorrectly paired, that is, instead of Putting Kingstone with Kingston and GoodRAM with GoddRAM, I put Kingstone with GoodRAM and after swapping it as needed, the bsod never appeared, so I suggest you look at this manual if you have memory banks paired with each other and insert memories in pairs, if you have a different manufacturer. In general, it is difficult to force different memories to cooperate with each other, so it is best to sell all the dice, add cash and buy the target capacity in two or one dice right away. Sometimes they are even such mega flowers that it turns out that the motherboard simply does not like the given memories and that's it. You can juggle the tensions as you want, you can juggle the timings as you want, and the album won't cooperate anyway, and that's it - it's just dice for other ones. Therefore, the safest solution is to check the manufacturer's website in the support section, read your motherboard and read the memory QVL list and buy the same as on the list. Then you have 10000% certainty that you simply do not have a whip, so that after inserting the arrow bones, they will not work with a given disc, because this list includes only those memories that have been checked on a given disc by the manufacturer and work without any type of shells. changing timings or tensions.
