Solved! Question about Rams

[Arl03]

Hello guys,

So i have this laptop that i bought about a year ago. Lenovo Legion Y720 with 8gbs of RAM, and im looking to upgrade and my question is... Can i just buy a random 8gb RAM to have 16gb?

The current RAM it has is a DDR 4 one with 2400mhz, can i just buy one with those same specs and have them work in dual channel with no problems?


Thanks in advance.

For best performance and compatibility, you should install matching memory. Mixing memory can produce undesirable results. Depending on how different the models are, you may/may not get them to work in dual channel mode.

So i should just buy a pair of 8gb sticks and ditch the current one?

Or maybe if i can get one with the same voltage and timings can it work?

No.

Maybe. Even with all specs(speed, type, timing, voltage) being identical there is no guarantee that a new kit will work with an old one. 95% sure it'll work but many of us here at Tom's have seen the 5% that thought they were doing the right thing by matching all specs and it still won't work. WHY? Tom's? WHY!?. Unless the RAM installed was purchased as a kit there aren't any guarantees where compatibility is concerned.

Why do you want/need more RAM?

If you want a 100% chance of compatibility, use matched (sold as a pair) memory. Otherwise, you won't know for sure until you try a mis-matched pair.

Dang, i guess ill have to buy a pair to be 100% sure.

One possibility.
