T420 memory upgrade


I've recently bought Lenovo T420 and now would like to upgrade ram memory up to 8GB. The original module is Samsung M471B5273CH0-CH9... Is there any difference between it and M471B5273DH0-CH9? Will them work in dual without problems?

Re: T420 memory upgrade

They should be compatible.


My T420 is running with a M473B5273CH0-CH9 in slot 2 and a M471B5273DH0-CH9 in slot 1 right now. I have had no issues.
