Lenovo Legion Go 32GB RAM Upgrade
Вставка
- Опубліковано 1 чер 2024
- In this video, I go over the process of upgrading a Lenovo Legion Go handheld PC from its stock 16GB of system memory, to 32GB. Unlike in my previous attempt at upgrading the Steam Deck, I had to manually modify the SPD data in the system BIOS in order for it detect all the installed memory, rather than simply flashing a pre-modified BIOS image.
The RAM chips can be purchased here (part number K3KL5L50CM-BGCT): www.aliexpress.us/item/325680...

My man woke up this morning and chose greatness. Seriously impressive work as usual.
can it run minecraft with shaders?

Yo salem bruh 💀💀💀💀💀💀
That's high praise coming from "the greatest technician that's ever lived".
Dosdude’s superpower is to be able to buy the entry level version of any product
This is cool to watch but you will have to flash the memory whenever you do flash a new firmware on the bios. So, if you are thinking of having someone upgrade the system memory, remember, you have to flash the memory everytime you upgrade the bios. This is info not told to people.
if someone is doing all this stuff, future firmware updates overwriting the bios is pretty obvious...
Dumping SPI_NOR flash is interesting 😅 just to make sure to unprotect the lock protection bits before writing
Well if needed it is not a big issue to write a patcher. Since it is compatible enough to boot even with original SPD block, soldering will not be necessary. As for initial installation it is easier to repair tech to work with spi directly.
If you have UEFI like this does, you don't. The board will normally do it on boot. It reaches out on boot to see hardware, then sees the RAM. If it's the same manufacturer ID, it will just feed them timing and JEDEC info to run at the speeds and latencies of the last chips just with more capacity. I know ASUS does this and Acer. I believe it to be a factory thing for DDR5 ICs. I've replaced my 8GB Hynix ICs in my Asus Zenbook with 315-ball SK Hynix ICs with 16Gb (8GB) ICs. 8x4=32GB. Make sure to use as close as possible, the closest IC you can. Timings, speed, and most important... Pad count. Mine are 315-ball pads. Makes the whole process easy.
Incorrect. "Flash the RAM"? Do you have any idea how dumb you sound saying that?
You're a legend dude. Changing soldered memory modules is probably more common than swapping DIMM's for you 😅
Always crazy skills !
I discovered your videos 2 months ago and since then I've been hooked 👍
Would love to see an Before/After test in apps and games
Nice work!
This is beyond my realm of understanding, but was still intrigued. I wish I had a friend like this guy! Well done sir!
Holy cow! Not sure how I ended up here. But that was a wonderful dive into high pitch soldering and hex editing.
Very well explained I could probably even do it now!
His voice is so soothing, it's like someone is scratching my head
u gay brah
I'm always amazed by how easily you can deal with those ICs with the tools you have! Well done!
I've seen many boards removal and soldering but this is the cleanest job I've ever seen 👍👍 salute!
Bro just hand swaps a BGA with no Xray no oven. Wild stuff bro. I worked as a SMT operator for years and this is impressive.
That's how we did it for years in repair shops, you don't need X-Ray nor oven. RAM packages are the simplest and easiest to replace. The fun starts when you replace thin substrate non-square CPU packages.
I made things for the military and medical field, so we had to X-ray almost everything for liability issues. It is still crazy how quick you are with the BGA. Love the content. Hope more people see this and learn such skills. @@FrozenHaxor
Oooh, those are LPDDR5X RAM packages, neat. Very tiny pads! Amazing they can squeeze 16GB into each of them, very cool.
Amazing work as aways! And that bios editing part was a great lesson.
takes me back 20 years in my career editing eproms.
i have been looking for this, thankyou thankyou🌺
Now this is educational and entertaining ❤
Wow this is amazing. Idk what to say other than great work and to keep it up. We all love it
Since iGPU and CPU use the same & shared memory, 32GB RAM is make sense. Love the details on this video
Why didn’t they sell us a version with 32 bg of ram? I would paid the extra 50-100$
@@Mercer696 they probably didn't think the device would get this far in tbh
God I'd hate to see just how tiny the stencils for solder balls of that small of a footprint must be. Sheesh, must be a nightmare. Also you made dumping, updating, a flashing a BIOS look so easy omg.
why is this so impressive omg and you did it very clean !
You definitely have a way of making a complicated procedure seem simple. I look forward to your next video . . . how to replace your own heart without missing a beat.
I subscribed and liked purely from the vid title, I absolutely love this sort of stuff
Absolutely fascinating. Thank you for sharing. I have no plans to ever do this type of modding, but I admire those with the knowledge and tenacity who can do this. :)
incredible skills! very impressive man.
Good job, thanks for hint with bios modifications
Very informative and educational. Loved how I could understand your instructions and maybe one day I could attempt a upgrade like this. 😊
way out of my league but boy i watch the whole vid , so fun to watch , thanks!!
Amazing video!!! I remember seeing when you did the same thing with the steam deck. I located in MD would love to have this service done with my legion go.
My boy another awesome work ❤️❤️❤️ definition of masterpiece
You make some of my favorite content right now
Amazing, the amount of different skill needed to do this is incredible, but seeing explained like this makes it seems really simple. I was most curious about the software part of the mod and this really given the information needed.
omg these guy is literally genius and so so im speechless im totally listening to your videos for now you deserve my subscribe keep it up dude:)
Wow... why I have the same feeling I had when watched Terminator movie for the 1st time when being a kid? Great work!
You're very talented at what you do.
that is a brilliant man !!!!! every single technical theories during the play which this experties in this realim thank you for sharing this vidoe for rest of product taker who can only image about to upgrade which is dram come true.
You Sir are a genius
Wow I didnt know this was possible. This is actually mind blowing
You seem like a computer scientist and a computer engineer stacked in one person.
Seriously impressive work ⚡⚡⚡
nice job Colin 👌
I love these kinds of esoteric videos, im with my people ❤
Great video, one question, if you update the BIOS will you need to modify the SPD data again?
omg you are a God!! So much skill you've got awesome abilities!!!
great work
most of us swapping rams and gpus, Bro is out here modifying the alien codes...awesome job
Pure Genius
I hope companies take note of these modifications for future devices!
Trabalho magnífico.
I would not even attempt to do this but good to know it can be done!
My question is, does the BIOS also have provisions to allow for more VRAM to be allocated to the GPU as well? Further modification could allow for probably a max of 8GB to be usable by the GPU leaving 24 for the rest of the machine to utilize, which in practice for some games is more than enough, especially considering some games need a minimum of 8GB to start no matter what quality level you're going to drop it to after to get it playable.
Really nice video când you do some testing in some games
fantastic work
absolutely awesome man
excellent video!!! It helped me a lot, just one question, where can I buy the support that you use to maintain the logic board while preheating it?
Excelente vídeo.. sayin that did you apply soldar paste to the chips.. wish you well
Impressive work!!!!
clean work man
salute to your experience
In the same situation rn . Using a Asus Vivobook Pro 15 OLED (2022). Wuould be awesome if you also take a look at it. Great video.
amazing work! Is the memory bandwidth affected after the upgrade?
Very nice job. I would like to know how much you charge for this and where are you located? Thanks! I would be happy to try doing it myself because you made it look easy but I don't have the proper tools like the hot air rework station and eeprom flasher.
Amazing and awesome!
Are the new RAM chips the same quality as the originals? Were the original chips HyNix? Great upgrade video! 🤓
amazing work can this be done to laptops with soldered ram?
Finally found your channel.
This is some next level sht.. what a legend..
This is amazing. I can't help but wonder how much you charge for a service like this. I take it that anytime a BIOS update comes out, you would have to remove the chip to edit it or it wouldn't recognize the additional RAM?
Nice, can you find faster RAM chips than stock and can the SPD data be modified to account for the faster speed? Looks like LPDDR5X goes as high as 8533 MT/s but stock it's just 7500 MT/s. Also curious if you can do a similar video for the ROG Ally. Thanks!
I'm surprised to see Lenovo did not use their black epoxy underneath the apu and ram - this was very widely used in their laptops, making repairs much harder than they need to be.
edit: I have a question on bios updates that wll for sure appear for this device and might be actually beneficial for it - like changing power limits, fixing security vulnerabilities and other fixes. As i was working with Lenovo bioses (specifically for thinkpads), the bios has to be digitally signed (not only digitally signed but signed porperly) for the device to properly update and not cause a bootloop or checksum mismatch - would an bios update work in this case? also, if it did work, it would probably overwrite the spd data with new values, again limiting the usable ram.
Just CNC mill the original ram chips to oblivion, epoxy underfill issue fixed: It is the way alot of shops do in iPhone storage upgrades.
Very good - thanks. Always a pleasure/
Awesome Video !
este tipo esta loco, buen video
Great video!!!
very nice. Has the 32Gb RAM had much effect on performance, and especially HEAT in the system?
Very nice work, sir. You could upgrade these for folks and make some $$ probably.
looking forward to when you do this to my rog ally
Amazing 🤩
Beautiful work enjoyed the video, How much would you charge for this?
Just literally stumbled upon this channel today! Nice work, now I’m wondering why Lenovo didn’t install 32gb themselves to give a superior device 🤔
Price lol. Lpddr5x ram is expensive
@@oo--7714not really
little portable gaming handhelds do not need 32gb of ram
most video games do not use more than 10gb of ram
I'm not sure if this is possible with my GPD Win Max 2, but I'd love to bump the thing up to 64gb like the newer occulink model, also sort of wish i had held out for that one just because that port is super unique and stuff, but you could say that about almost all computer hardware tbh
Hey Dosdude! I’m a huge fan of your work (especially on the 2012 17-inch MacBook Pro) and I’m just curious, the limit of ram for the unibody MacBook Pros were 18gb of ram. With your knowledge about these MacBooks, would it be possible to make changes for 32gb to work? Changing the logic board or firmware, could make 32gb possible. I don’t research about this type of stuff, but I’m just curious about this challenge of getting 32gb to work.
Bu adam bu işi iyi yapıyor.
dudee you are the best❤
Amazing 😮
Videos like this one or the one for the Steam Deck intrigue me, but what would actually be the maximum memory possible for a device like the Legion Go? Also what difference in performance would it have for the system, as you did not do any benchmarks or anything to test out the capabilities...
Nice work :)
Impressive!
Respekt, dude.
I know very little about this stuff but could do it with if i had all the equipment anda video like this. Also i was surprised i knew what chip you was going to pull.
hi bro, great content, is there a way to reapply more edge bonding to the chips when you finish changing them or there is no need to reapply it?
No need, it is unnecessary.
What temperature do you preheat at? Also what temp do use your soldering iron at? Trying to learn how to do all this stuff lol
Just a question. This prehaeter you use, is it essentially like a heating pad? What kind of temperatures you use on it, 70-80c ? Because for this chips usually don't you go for 380c on the hot air station like nand, is 330c enough?
@dosdude1 I have been using your Patcher's for a few years and watch your soldier videos on UA-cam alot. I was wondering if you would ever make Patcher's for the newer Mac OS's Patcher's after Catalina?
Can you also modify the clock speed and time of the ram using a higher quality or tighter timing chip? Curious what what that would on some of these APU's.
amazing 👍👍👍
The Rog Ally and the Lenovo Legion Go are my favorite handheld pcs. Msi claw and sh*t deck belong in the trash.
Was there a performance upgrade? Also, about how much does it cost?
only question i have about this is what about the newer bios? The april 22nd bios updateni noticed was a bit of a performance increase
i noticed an improvement in your video's quality, did you get a new camera?
Yes, indeed I did.
If you type "cmd" into the address bar of any folder, it'll launch command line with the pwd at that location. Saves you a couple extra steps.
