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?



    This guy has a good guide on possible upgrades.  He recommends battery and I can see why. Seems like a big jump in battery life. 

  • oh snap i was scared of upgrading to more than 16gig but i also installed a ssd and a m.2 drive

  • Thanks for the info... really helpful. I just got me a Legion 7 AMD Ryzen 9 5900HX with Radeon Graphics 3.30 GHz, but I'm not too sure if I made a good purchase. I got it for graphic design, video editing, and gaming too. I'm not sure if I should keep this laptop or get me a desktop. Do you have any suggestions or recommendations. Any will be good. Thanks...

    Ja, normaal gesproken zou je ermee moeten kunnen spelen of er grafisch werk mee moeten kunnen doen.

    Het hangt ervan af.

    of je nu een videokaart (nvdia) of echte Radeon vga-kaart hebt met 4 of meer vga ram of (Integrated)(Radeon Graphics), Integrated is dat de grafische kaart op de processor staat en meestal maar 2gb ram heeft, dat is grafisch werk mogelijk maar beperkt en alleen eenvoudige games. Als je een echte vga-kaart hebt met 4gb vga ram of meer dan is bijna alles mogelijk, afhankelijk van de hoeveelheid ram geheugen die je hebt. Ik bezit Legion 5 Pro 16ACH6H laptop met Nvidia RTX 3070 met 8GB vga ram en systeemgeheugen van 32 ram AMD Ryzen 5 en kan er alles mee op volle snelheid en zonder beperkingen. Ik speel de zwaarste spellen met de hoogste instellingen en het loopt perfect. Ik hoop je hier een beetje mee geholpen te hebben. Wat Lenovo betreft, heb je echt een goede keuze gemaakt, ik gebruik al vele jaren Lenovo-laptops en -producten en het heeft me nooit teleurgesteld.

    Groetjes Evert.

  • Sorry for the delayed reply. The battery is a huge problem in this laptop because the system draws so much power, it's actually unstable and can't run games well on battery alone. This is a HUGE oversight on Lenovo's part to put such a useless battery in this laptop. Then again, maybe they knew this and just decided to role with it anyway. I have not checked out this video yet, but I do plan on it. I have done some other mods as well, and will be posting about that shortly. 

  • Yeah, I was concerned as well, but with my years of experience, I could find no reason that this should not have worked so I decided to take the chance and I am glad I did. The extra memory was well worth it and the results have been awesome. Lenovo seems to like to be in control because some people should just not ever open a laptop and mess around inside, then Lenovo would have to pick up the pieces when they blow up their machine. This is likely why they say it's not supported so they can save themselves the trouble from those who venture where they should not. However, for those who have the experience and don't mind taking the responsibility if they mess things up, then upgrading is worth doing. I just wish Lenovo would spend a little extra time whitelisting more hardware options. 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.

  • Are Kingston Fury Impact 32GB 3200MHz DDR4 RAM compatible with Lenovo Legion 5 15ACH6H? Thank you in advance

  • do you think that will be work with  this model 17ACH6 part number 82K00043US ram from 8 GB to 32 GB with ryzen 5 and gtx 1650 and 60z monitor ??
