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.
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.
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!
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
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.
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.
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.
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.
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. :)
Great work. I hope Lenovo looks at the video on what the next generation RAM should have, along with the next generation APU and at least 1 gigabyte (better 2) PCI 4 SSD. Then they will stand out from the crowd of handhelds.🥰
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.
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.
Hello, I was wondering, If we (you) can already change the 16gb RAM chips for 32GB ones, could we hot swap the APU of the Lenovo Legion Go with the 8840U APU? I did a little bit of research and it seems like that the APUs are the same size, some of the compoments are the same..
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!
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.
I believe what genius accomplished here is to be able to run 8 gigs safely on handheld mode, and then remove the bottleneck the CPU ram poses when on eGPU
Note: I contacted both guys about this upgrade for my Legion Go. One flat out told me the upgrade had been unreliable for people due to poor quality chips, so was no longer doing it. Maybe oneday we will get better chips, not China sourced?
You are that kind of guy like in the movie where an astronaut that can fix any problem in his shuttle / satellite with only a screwdriver, jumper and perhaps also solder.
So if you don't edit the firmware after the upgrade, the system still boots, but doesn't use the rest of the RAM. Does this mean that if you didn't perform the upgrade but still did the firmware edit, or otherwise told the system that it has more memory than it really does, it would try to write to nonexistent memory? Is there even some defined behavior that's expected to happen in this case, or can we just expect it to totally freak out? Also, I thought modern chips wouldn't load firmware unless it's signed by a key burned into the chip. But obviously this mod makes the firmware no longer signed. Have I been misinformed? Isn't it unnecessarily risky to desolder the firmware chip and solder it back to the board? I thought you could just write to it from within the OS? That's what firmware update utilities normally do, right? And if not, aren't there clips to attach to them?
I think it should break TPM measurements, but that doesn't stop boot - some features, e.g. Bitlocker, might be broken though. There is also usually signature verification for updating BIOS from device, which is probably why update from the OS wasn't done (in addition to having to read the BIOS first anyway) and it was desoldered and written to more directly instead. As for clips, I'm not sure if there are any easily available for this specific package, but it might've just been that the author didn't have one.
Me: wow, doing all that small soldering and prep work looks kinda tough. I could probably learn to do that. Me, once he started talking programming stuff: what is this sorcery!?
Is it worth it? I used to have Ayaneo2 with 32GB and it is easy for me to play game that require a lot of vram. I'm not sure about this one as when the bios update or system update, I'm not sure what to do.... I asked this because I'm currently studying in China and there are places that offer to upgrade the RAM.
There would be no space for laptop dimms or those micro memory pads as dimms? That eeprom segment was something, I think I just gained neurons just by watching that modif. segment leaving the park of apes to the glory of the wheel and all sorts of applications it could apply to.
Lenovo's ThinkPad X390 Yoga RAM memory is soldered and NOT user upgradeable. Would it be possible to do an (reballing) upgrade of the RAM modules of the motherboard?
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.
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
Nice, I want do it but want to wait for the USB flash version for the BIOS since I don't have a reader. Nice to see you can still use the Go with the new chips with modifying the BIOS.
My man woke up this morning and chose greatness. Seriously impressive work as usual.
can it run minecraft with shaders?

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!
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.

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 😅
You make all these upgrades and repairs seem so easy man I can't stop watching
Always crazy skills !
I discovered your videos 2 months ago and since then I've been hooked 👍
His voice is so soothing, it's like someone is scratching my head
u gay brah
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
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!
most of us swapping rams and gpus, Bro is out here modifying the alien codes...awesome job
Amazing work as aways! And that bios editing part was a great lesson.
takes me back 20 years in my career editing eproms.
I'm always amazed by how easily you can deal with those ICs with the tools you have! Well done!
Now this is educational and entertaining ❤
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.

32 GB of ram on the Legion Go will make games perform even better than they do on the Ally X. Nice!
i have been looking for this, thankyou thankyou🌺
My boy another awesome work ❤️❤️❤️ definition of masterpiece
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.
incredible skills! very impressive man.
You Sir are a genius
Good job, thanks for hint with bios modifications
thank you for this tutorial it has helped me well step by step i now have 32GB RAM this was so easy to do!
Oooh, those are LPDDR5X RAM packages, neat. Very tiny pads! Amazing they can squeeze 16GB into each of them, very cool.
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.
way out of my league but boy i watch the whole vid , so fun to watch , thanks!!
You seem like a computer scientist and a computer engineer stacked in one person.
You make some of my favorite content right now
I haven't words, it's amazing work and skills.

I hope companies take note of these modifications for future devices!
Wow... why I have the same feeling I had when watched Terminator movie for the 1st time when being a kid? Great work!
Wow this is amazing. Idk what to say other than great work and to keep it up. We all love it
Excellent video. Holy Sheet! This is well beyond my patience and expertise. I would definitely pay someone to do this mod.
Pure Genius
I subscribed and liked purely from the vid title, I absolutely love this sort of stuff
Great work. I hope Lenovo looks at the video on what the next generation RAM should have, along with the next generation APU and at least 1 gigabyte (better 2) PCI 4 SSD. Then they will stand out from the crowd of handhelds.🥰
i didn't even understand anything on the video but was entertaining enough for me that i watched all the way to the end
why is this so impressive omg and you did it very clean !
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.

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.
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.
Very informative and educational. Loved how I could understand your instructions and maybe one day I could attempt a upgrade like this. 😊
Wow I didnt know this was possible. This is actually mind blowing
I love when my dumps are completed successfully
I love these kinds of esoteric videos, im with my people ❤

I've seen many boards removal and soldering but this is the cleanest job I've ever seen 👍👍 salute!
I would not even attempt to do this but good to know it can be done!
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:)
Trabalho magnífico.

Maybe oneday we will get better chips, not China sourced?
This is some next level sht.. what a legend..
omg you are a God!! So much skill you've got awesome abilities!!!
You're meant to conquer the world.
Amazing
You are that kind of guy like in the movie where an astronaut that can fix any problem in his shuttle / satellite with only a screwdriver, jumper and perhaps also solder.
It’d be cool to see this done on the ROG Ally.
I've actually done it successfully on the ROG Ally as well, it uses the same chips as the Steam Deck.
Great video, one question, if you update the BIOS will you need to modify the SPD data again?
For sure!
Are the new RAM chips the same quality as the originals? Were the original chips HyNix? Great upgrade video! 🤓
Really nice video când you do some testing in some games
Great video, I'll just wait for the LeGO v2 with hopefully 32GB out of the box and Occulink.
very nice. Has the 32Gb RAM had much effect on performance, and especially HEAT in the system?
great work
The Rog Ally and the Lenovo Legion Go are my favorite handheld pcs. Msi claw and sh*t deck belong in the trash.
Seriously impressive work ⚡⚡⚡
Очень тонкая и точная работа с вашей стороны 👍
Props to you for using Windows 7 still.
Do you need windows 7 for the spd data software thing
So if you don't edit the firmware after the upgrade, the system still boots, but doesn't use the rest of the RAM.

Me, once he started talking programming stuff: what is this sorcery!?
How much more performance can u expect for this upgrade?
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.
You're awesome. Please test it with some demanding game.
I wish this were a more common process around the world... Many of us will be left wanting forever
Great video! Two quick questions.
1. Can this be done with 64?
2. Will you run into any issues with future official bios updates?
This is the only thing keeping me from getting a GO, 16GB RAM.
Is it worth it? I used to have Ayaneo2 with 32GB and it is easy for me to play game that require a lot of vram. I'm not sure about this one as when the bios update or system update, I'm not sure what to do.... I asked this because I'm currently studying in China and there are places that offer to upgrade the RAM.
Dude you are incredible, but this is something i would pay to have done, jesus!
nice job Colin 👌
There would be no space for laptop dimms or those micro memory pads as dimms?
That eeprom segment was something, I think I just gained neurons just by watching that modif. segment leaving the park of apes to the glory of the wheel and all sorts of applications it could apply to.
Man I thought it would be easy...
Great work tho
wow - at least you make it look easy :)
It's pretty easy if you have the right tools, it's not rocket science
Lenovo's ThinkPad X390 Yoga RAM memory is soldered and NOT user upgradeable. Would it be possible to do an (reballing) upgrade of the RAM modules of the motherboard?
absolutely awesome man
Very good - thanks. Always a pleasure/
I need a friend like you close to my area,
surely I will paid for that just for a peace of mind.
salute to your experience
You know what, if I ever want to do this might as well as make it 64GB
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.
can you share the modded bios so we can just flash instead of editing it?
The BIOS images have unique IDs for each machine stored in them, so it is best to modify the existing BIOS.
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.
How much would it cost me to send my legion go to you for this memory mod?
Are you doing this as a service? If so, how much?
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
