Ballistix Sport LT 32GB DDR4-2666 SODIMM
 

"Even though Ballistix Sport LT doesn't look like top overclocking memory, it has really high overclocking potential and offers high performance even at default settings. There were no issues at all with compatibility or stability of whole platform in nearly three weeks of various tests."
