While stripping out a computer preparing for recycling I took out two 4GB sticks from Samsung labeled 1Rx8 PC3-12800U-11-12-A1. I've another machine with two sticks of 4GB Hynix memory labeled 2Rx8 PC3-12800U-11-11-B1 installed. Can I install the Hynix into the system using the Samsung sticks without operating problems?
