Memory upgrades for Legion 5....

So I am hoping that I have chosen the right group to post this to. When I purchased my Legion 5 17in Laptop, I was told by the support rep, that upgrading any hardware would void my warranty... Now, as gamers, we all know that upgrading hardware is a must, as we all strive for better faster FPS and improving our gaming rigs for the best gaming experience. Hearing that upgrading the laptop would void my warranty was troubling, so I contacted a manager at Lenovo and poed the same question, and he advised me it would not as long as the upgrades were done with compatible hardware, preferably with hardware approved by Lenovo, bbt that was not a requirement as Lenovo does not have a very comprehensive list of approved hardware. 

Wen I purchased the laptop I was only able to get a max of 16GB RAM, and it came with 16 GB DDR4 2933MHz.  Lenovo says that this laptop can not handle any more then the 16GB, however, I did a bunch or research on Google and found a number of people who had infact upgraded to as much as 64GB, but it seemed that the majority only went to 32GB. So I did some searching and no memory manufacturer listed ths laptop as compatible with any memory other then the basic 16GB DDR4 as apparently they are only able to list memory that Lenovo says is compatible. So after some additional searching I found that this laptop can actually handle DDR4 3200MHz ram, and so I decided to give things a whirl and ordered Kingston HyperX 32GB DDR4 3200MHz ram. 

I installed it and sure enough, the Legion 5 handles this RAM perfectly fine, and it has had a marked effect on my performance. Games are running much faster, and I am getting up to 180 FPS on some games, and while the games I play are not the FPS games i used to play, I can tell you from experience, I don't think they will have any problems whatsoever on this laptop.

So my question is, has anyone else upgraded their memory or other hardware, and if so, what has your experience been as far as improvements etc. I would be interested to know what else others have upgraded, and if anyone has upgraded their memory which have you used?

Cheers!

  • It's a late response but still relevant. Simply upgrading RAM is not going to void warranty. The reason they say this is because if you choose a kit that is not compatible the go to response would be to blame Lenovo and tell them to fix their junk device etc. This would be of course your fault and not their responsibility. If you know how to choose the right kit then you would not void a warranty. If your processor is Intel based then you would need to find the specific frequency and channel that is supported by your processor to choose what would best work with your laptop. In laptops that allow overclocking for example it typically is more critical to choose the right product because if you mess with voltages or put a power hungry kit in there it could short the board which of course would fall on you. It's a scare tactic yes, but with some research you can improve performance without hurting anything. 

    Secondly, if you mix and match kits there is a possibility that you get blue screens or worse performance since RAM will typically down clock to the lowest performance of whichever module is weakest in your laptop. So for your upgrade if you chose a 3200 kit thinking it must be faster but chose a bargain kit that has worse latency and is running the much slower x16 rank. that would reduce performance by up to 20%. BUT back to topic if your processor cant support 3200 natively it would down clock to the highest it can support assuming your ram can run that speed as well otherwise whatever the lowest common speed both can handle. 

    This obviously isnt the specific case for you since you claim an improvement but just giving some additional context for anyone interested in knowing a smidge more. Here is a quick video for those wanting to know about the RAM rank performance deficit. www.youtube.com/watch
