Well that's interesting, I did the opposite. I bought the xps 13 9350, and the Intel 8260 in there was terribly unstable. I opened it up and put in a killer 152

Well that's interesting, I did the opposite. I bought the xps 13 9350, and the Intel 8260 in there was terribly unstable. I opened it up and put in a killer 1525, which also was unstable. Then I replaced it with a killer 1535 and it's worked perfectly ever since. Perhaps the 8260 was just a bad model?
