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?

Should be ok even though one set is dual rank and the other isn't. just match the 1R pair with 1 set of slots and the 2R with the other two slots. Even mixing them wouldn't be a problem just not optimal.
