Hello everybody, please i want to add second memory into ProBook 4340s, one is YKO ddr3l and other is cko ddr3. Motherboard and i3 cpu supports both voltages 1,35 and 1,5. Should i have any concern about cooperation between these 2 memory? Or there should be no problem and this will work just fine? Thank you in advance for answers

I generally avoid mixing 1.5 and 1.35 volt memory modules. 1.5 volt module will not run at 1.35 but 1.35 volt will run at 1.5. So if you install both they will run at 1.5 volts. May not run in dual channel but I think they will do that. In other words, no major reason not to install both.

Thank you, could this combination Hurt to memory controller? I tried that and cpu z shows one memory with voltage 1,35v and other with 1,5v but It looks stable.
