I bought this Ram set as I've fitted it to a previous computer which performed very well. On this occasion, the new computer build worked well until the system was put through a little stress, such as playing Fortnite or Minecraft. On these occasions the system regularly crashed to BSOD or completely off . After much testing, it turned out to be a faulty stick of Patriot Ram (tested with Windows 10 memory test and Memtest86) I appreciate that sometimes Ram can fail, BUT, if you look at the Amazon 1 star feedback for this Ram, there are numerous reports of these Ram sticks failing and furthermore, apparent abdication of responsibility by Patriot. It seems that the problem could be incompatibility with Ryzen generation 3 processors ( I'm no expert, but mine failed with gen 3 and many other people have said the same) Anyway, as soon as I changed to Corsair Ram, the problem has completely gone. On a positive note, good customer service from CCL, and Ram returned and refunded.
