Razer Blade 15 - Can we use RAM power supply for VRAM? Going the extra mile for the customer 

That wire didnt worked because its not proper calibrated.

Hello sorin. That was my laptop and thank you for helping me fix it. I've managed to fix the windows issue and everything is going well. I know now to never trust razer again.

This has got to be the dodgiest attempt so far lol.😂

These are not the kind of content you'll find in other channels, you could only get it here. That's why you're a LEGEND sir. #undisputed 😂😂😂

what about adding a cheap switching power module. At 1,35v not 1,2v .... gddr6 require 1,35v. In alternative, you can take it out from spare motherboards. Time ago there was a trend in the gaming community entusiasts .... they ake the gpu psu from old card, like 690 to use it with newer gpu to pump as much power possibile. So, it's not impossible at all. A bit complicated, but doable. The main problem with a laptop is the space.

„Lol, we have a picture” - I heard it in my head when I saw the thumbnail…:)

6:52 -- it's time for 'say hello to my little friend' 😂

Sorin! So many possibilities that end up in landfill and pollution and customer loses because someone does not want to even try and it's such a waste!! Thank you Sorin. Thank you for doing this and getting the job done!!! So many people back out too quickly but NOT you! which is why you are the MASTER! And those saying dodgy lmao. Everything is dodgy! It comes from factory dodgy! It was so dodgy it blew up in the first place! It's dodgy all the way down LOL

Sorin, in GPU-Z you did the render test on Intel UHD! (@33:10). The 2070 is GDDR6, which may require 1.35V, depends on the manufacturer of the chips. Samsung can go as low as 1.1V, but only on later revision chips. You would need to run a proper GPU benchamrk - like Superposition, Heaven, and Furmark. I don't think this 1.2V can support 3 things at load: RAM, VRAM, and Memory Controller (that is inside the nVidia chip).

Sorin you made me laugh a lot 😂. Great as usual 👍

I think you got the wrong model, this is Razer Fried Chicken 15😁

Sorin the VRAM test with GPU-Z was on Intel Graphics!!! Look at the Intel Logo 33:05 u must switch to NV on the app. The Laptop was Online and installed Drivers on 34:06 thats the reason why the display turns off/on. Your work was maybe good ;)

What a fun attempt.. it was so relatable seeing Sorin going "yeahh i cannot repair this..." A bunch of times while on his mind is 100% going "but maybe.." It's a shame that even with the gpu and vram still working it cant be repaired.. It really sucks that razer has one of the nicest build quality on laptops but they're so unreliable.

Held me on the edge of my seat, not gonna lie. Nice one!

Sorin, you and your work are fascinating...Love it☘

That red underfill is the stuff of nightmares.

I believe the memory voltage for the GPU's GDDR6 is 1.35 volt, 1.2v might be insufficient. Also in the GPU-Z software, you can select at the bottom in the GPU list the correct graphics (switch from intel to nvidia)

we need part 2 of this

Really enjoyed this one. 👍

Sorin, you could use two Dc-dc Step Down Lm2596 3a Ultra Small Smd Mp1584, one for each coil!

I like seeing Soring having so much fun :D dodgy style fun :D

Love your videos. Thank you 🎉

What ever you do as long as the laptop is working.. I really love it the way you work, and yes I'm on the right channel! thanks for sharing😇.

My innitial thought was just remove the components, clean up the board and dont make it any worseby digging out the rot: replace the mosfets and close it up. However I then thought the burned layers are like rust. You have to dig out all the rot in order for it to be a proper repair. Once the board is stable and safe, then replace the mosfets, and reconnect all the paths so its function is mostly returned.

Yo veo tus videos por que aparte que explicas de manera muy entendible, tu ingles lo entiendo a perfección. Gracias!

Why I loved this post is because I wanted a *razor, "nearly pressed the buy button". But take note the drive to thin configure left a specific and huge problem as motherboard with heat failure. The elegant repair shown, in fact managed whole operation, but shows where the larger issue as design "has a fatal flaw." As a sold product, it is fact as consumable, a time part to failure. Note, in many modern auto's, module end use also has a fail rate as "built in". I cite LED tail lights, for an example. Should I have been this customer, I thus, would have liked to see the underlying fail problem, as to simply know why (and what went wrong). *The burning smell as #1 issue. But such repair, may have allowed salvage as data. (files, photos, ect.). For the tech at work bench, I take notice of the best methods. And the work flow as to determine fault, and repair where possible. * I am never afraid to "brick" a unit, but where also, I work outside of sales. In the end, I am cheering as this view conquered fault. What ever built in design was unworkable as full long term repair was at least, a restore to operation and the reason as "why".. "revealed". I am a huge fan, and in awe as to see a master at work, with such fun commentary. My multi-meter beeps, but not to the skill shown to my delighted view as to watch and gain lessons. M.

I take it from now on we are all to collectively known as Sorins Bad Boys?!

It was fun and exiting even to watch closely!

Try to fix the board with green mask to isolate the layers then fix pads. Then you can rebuid original cicuit.

Ok…. Still a great repair… not a gaming laptop anymore, but good enough for general use… AND you had fun… AND learnt new things…. Not your fault if the manufacturer underdesign things….

You should add external alim module fixed with hot glue loool. i love your post apocalyptic technic , robots will be happy !! Sorin you are the best :-)

Sorin.. you can try to use the heatsink as a cooper conductor.. if you need a lot of cooper, you have it :)

me encantan tus videos siempre los subtitulo, en verdad queria ver esa reparacion... cuantas capas son ahi en ese crater ¿en verdad no es posible repararlo recontruyendo pistas y mascara uv ? , obvio 2 o 3 capas pero si ya son 7 no le veo el cazo

You have to do your best for the knowledge that you have and keep on using best tools to fix any laptop pc gaming FC-DLH

satisfied here and engoyed the try!🤩👍

Very nice

Alternative power supply worked but its not permanent fix. its good job for learning

Try to print a separate circuit for MOSFET and plant it

This is what u call proper dodgey😂😂

nice one .I always do this on the phone but I use resistor to protector anything happen to other side .but not on laptop i have never try pc repair 🤣

you are really great

Why don’t you use SMPS in order to supply that voltage, like adjustable LM2596, it can provide more than 3 Amps . You did that before , so please share your information with us .

Here we have a NIIIIIIICE laptop to repair! 😎😀

amazing as usuall! but dont you think the power supply of the system RAM dont have enough power to supply to both RAM? isnt that will make the RAM power supply running constantly at it limit and might burn it too?

benzer bir olayda dc to dc conventer kullandım. oldukça küçüktü ve işe yaradı. müşteri geri gelmedi.

lol entertaining. surprised it somehow worked. i have some idea how much vram power is and you are going to need more than 10amps for the wire.

Isn't it possible to put down some solder mask and then solder 2 replacement VMOS chips?

Sorin, How could we tell you about the screen connector when this isn't a live stream?

Best way to avoid being sad customer is to buy good gaming laptop then disable CPU turbo boost and undervoltag gpu then be safe

Should make a spreadsheet list of brand, model, and fault, then we know what brands have problems, ie, what not to buy.

the heatsink is copper maybe use it to transfer voltage.

Solder a wire onto the pad and route it the shortest way outside the laptop case. This way, he can hook an external power supply to the wire when he wants to use the GPU.

SIMPLY AMAZING 👏 Best yet 😂

You don´t need screen, why don´t you build the USB Tester with a STM32 ST-Link programer!? just plug it to a usb port and it will emit a sound when you "have picture" :o))

Hi Sorin, I noticed that when you were in GPU-Z you had the Intel GPU selected instead of Nvidia. If you still have the laptop try again but on the first page at the very bottom you can change the GPU, then try the render test. Cheers!

Wouldn't it be possible to create simple small circuit, for it to still power from USB5V, and drop it to 1.2V or whatever, and place it inside there somewhere?

GDDR6 runs at 1.35v .. fault seems so easy to fix but in reality there is no way you would fit 20+ amp stepdown in that space. Nice try anyway, shame it's realisticy imposible to do it in that limited space

Why didn't he put one of those tiny buck converters in there fed off the 19.5V? He did that before.

VRAM voltage is definitely not fixed. But artefacts may imply that some of vram chips got toasted. What do you think guys?

Sorin, in gpu-z you were looking at the Intel gpu clock, not the nvidia Look botom right corner (Intel UHD 600)

i want to buy a T-shirt from Sorin with ``We Have Picture ! `` logo ,....

What's with the stains on the ram sticks, never seen that before

WIth all the "dodgy" mentions I wonder if I have come across another wild diode watcher : )

Razr needs new pcb design or higher quality material( copper layer)

33:45 look at the very bottom, you are stress testing the on board gpu not the nVidia.

the screen data cable being on top of that heatsink terrifies me

We have picture ❤

"a beautiful laptop", well we hadn't had this before 😊

I keep saying, electronic components work with smoke, as soon as the smoke comes out, they stop working 😂😂

Nice video, but now we have another sentence...We have picture!!! That's crazy!!!! Jajaja

39:03 how is it that you are unable to check ? You can see volage drop across a wire under load

Gddr6 nominal voltage is 1.35v not 1.2v

Which laptop do you recommend to buy

gpu and vram voltage are variable, based on needs!!! frequency is variable, so the voltage!

you have soldered wire after coil. but what if you solder it before ?

BAD BOYS 🤣🤣🤣🤣🤣🤣🤣🤣🤣 I LOVE DODGY JOBS NO REALLY THANK YOU SO MUCH SIR❤

give it back to the customer

Awesome Dodgyness...Solid Gold Wire..!!...lol

Sorin desktop GPUs with artefacts can be repaired??

The Gpu will work with a phase missing

new dodge level unlocked

Dodgy-bodgy every time a winner. 🤣😂😆

maybe if you downclock the memories it can last longer

It needs a buck converter hook up on the main power rail

Postez pentru cã e muncã romaneascã 🤣🤪şi eu am lipit vreo 50 de fire sã leg placa de bazã ruptã în douã, de la un casetofon, copil find 😎

This was fixable! There wasn't that much burn and only a couple of traces missing. Laptops like this without their dedicated graphics are just paper weights.

They make laptops single use only....in no time like camera s

why don't you use JLC PCB to create a lay out for only the DRMOSFETS Sorin and stick them on the board should work right? I mean it is such a waste for the cutomer to disable a good GPU!!!

🎉

👌👌👌👌

Why can't you use an external power supply like you used in your old works

1.2v L super velocie

That was awesome fun... But as you said, in the scheme of things, the length of the supply wire introduces huge losses. If the RAM power supply was in closer proximity to the VRAM location it would have been better, but the long term stress on the RAM power supply would undoubtedly prove to be fatal... My hat goes off to you, that was a great proof of concept.

use an exteral strepdown converter 3A

Razr- defecetive laptops=BANCRUPCY FOR MANUFACTURER

Sorin....you are constantly humiliating the OEM's and educating the end user that tech can fix their laptop whatever the damage is.😅

You can't win them all, this is why i prefer desktops in a large case with plenty of fans. If the graphics card fails it can be replaced, but not in a laptop without replaced the whole pcb. The reliabilty of gaming laptops is never going to be great.

Late Night with Sorin O'Brian. This is going beyond dodgyness, it's a comedy show ...

Secondary issue?

❤❤❤🎉
