ultimate99 Posted February 1, 2014 Share Posted February 1, 2014 I got a new laptop with a 4gb ram (1600). Would performance be affected if I use an older 4gb (1333) from my t420? T440p, Win8.1 pro, i7 4700MQ. Link to comment Share on other sites More sharing options...
Hum Posted February 1, 2014 Share Posted February 1, 2014 You should list your Operating System. Read your Owner's manual. Download it if you do not have one. I doubt you will notice much difference in performance. Link to comment Share on other sites More sharing options...
xendrome Posted February 1, 2014 Share Posted February 1, 2014 That CPU supports - Supported memory: DDR3-1600, DDR3L-1333, DDR3L-1600 Is your 1333 ram Low Voltage or regular, regular won't work. Link to comment Share on other sites More sharing options...
snaphat (Myles Landwehr) Member Posted February 1, 2014 Member Share Posted February 1, 2014 Sure, everything will clock down to 1333 (well 666Mhz x2), but as hum said, you probably won't notice in practice. goretsky 1 Share Link to comment Share on other sites More sharing options...
