Watch the last part he used shield. It slid over some caps / resistors. Hopeing he sees my main comment.

As all the voltages are present (especially the core and memory), that means the core is fried. Which also means the owner has a very slow short-circuit-response PSU. It goes to show why it is necessary to get a good PSU. I had a similar issue where one of my drmos was fired during a gaming session. But Alhumdulillah, thanks to my PSU's fast SC protection, the 12V could never reach the core, and I was able to save the GPU just by replacing the drmos.

I mean, all their 30 series cards' 3rd 8pin pulled less power than the the two 8pins, so they never hit their TDP and sucked at OCing; junk IMO. If NVIDIA made them do this, I have no idea why. I wasn't sad at all when EVGA died.

Quite a delicate touch @12:32! Just enough pressure to grab the fuse and place it, only took a little jet of air to knock it away. Electronic surgeons grip!

Alex, what a tremendous service you do for this community. You really show the viewer how the repair is done correctly. Thank you very much.

A good way to identify which driver mosfet is shorted is to use an esr meter across the coil. The esr meter will read the esr of the coil on the good mosfets. The esr meter will read low resistance on the shorted mosfet.

After watching North Ridge Fix for so long. I got exceptionally good at diagnosing and repairing electronics. So good in fact I took it to the next level. I removed my own tonsils and filled a few cavities in my mouth. Next week I'm removing my appendix. LOL

I enjoy learning from each video. Thank you for being a great teacher.

Thanks for the manufacturer of that MOS that suffered a lot of hot air that you applied.and still working

Wow! Never saw this kind of Electronics Repair, Thank you for Showing.

I had the six-beep issue with a couple of EVGA cards. It could be a bios modified card. Reflash the bios and try again. Some EVGA's also have compatibility issues with older series of CPU's on the motherboard.

I'll print out my new art for framing and hanging. Looking for a possible fix tomorrow. Have a good evening Alex and gang.

Glad you have a supply shop as well 😉

How much is it costs for manufacturers to add voltage protection to gpu? I doubt it is more than $20 for all mosfets lines.

Hi sorry for a silly question. Does adding flux help at all with heat disapation and old solder flow helping removal. I assume not as you never seem to apply flux during the desolder process

@KyleSand

9 ай бұрын

Makes the solder flow where you want it and wet out the desired pad by breaking the surface oxidation/tension of the solder. Flux is acidic.

I am surprised that there is no warranty on all those relatively new graphics cards with burnt connectors and components that just fries like that. Seems like it is risky to shell out money on a very expensive graphics card when they can burn out, so easily.

Isent there a heat glove when soldering

Yes additional charges for hazard

I see an opening for hazard pay. ;)

Ok replace the GPU from a donor board. J/K boss! 😅 Show us part 2 tomorrow.

Alex What multimeter probes are you using ?

Sometimes you wear gloves, but not always.. Is there a reason regarding what type of board you're working on?

A susbcriber learns just by watching Alex's videos.

It's possible that one of the memory chips died, but they can be replaced and fixed with a reball, which is understandable that Alex don't do that kind of work for being too much time consuming for what is worth.

Yea that power stage died and probably took the GPU core and memory along with it. Another reason not to push cards too hard, keep the power delivery system running in a more comfortable range for durability. If you want to overclock like crazy you really need to buy the very high end boards that go out of their way and use overkill power stages (like those on the Strix) which are much more able to handle the high power requirements when overclocking, and they don't run as hot.

I'm a little curious why these expensive video cards are used. This one costs 3X the price of a PS5. Other video cards cost more than this one. There must be an attraction to PC gaming over game consoles that I am not aware of and I'm hoping someone can give me some idea what that is.

@lemagreengreen

Higher resolutions, better graphics features, higher frame rates. Basically the top end of gaming, PS5 is fine and all but it doesn't come close to what a high end current gen PC gaming card can do. It has always been an expensive way to play games. Some people will also use cards like this for work, 24GB cards like are quite capable as workstation cards... but obviously not this one which is just for running the latest and greatest games well.

Another "no fix" without proper testing, lol.
