My GTX 570 died. Is there a way to revive it?

[DigDog]

just dont forget about it in there.... the fumes are toxic

meh .. a bit of solder fumes never killed anyone. we used to solder in middle school, never used masks or anything. 100% survival rate.

Hello again everyone.

I finally proceeded in the baking solution. Unfortunately nothing changed. It was a fun experience though and I didn't smell any fumes either.

I cooked it at 210C for 10mins, with the oven preheated and I opened the door and turned off the oven when I saw the solder glistering. I left it inside to cool with opened door, so it wouldn't cool rapidly.

In any case it didn't work as I said.

The reason I am bumping this thread, is because I noticed some capacitors being a little pumped on their top.

Sorry for the thumbnail but it's a large photo and I wouldn't want to catch mobile users by surprise.



Now it you look closely at the 4 red capacitors on the right, the ones that are on a straight line underneath each other, they are a little pumped. They are not exactly blown but there is an obvious difference if you compare to the 5th red capacitor that sits by itself right next to them. This one has a completely flat surface on top.

Now is this an indication they are bad, or is this normal?

Also I measured their Ω resistance with a multimeter and they were showing different measurements.

A friend told me this was normal and was due to the capacitors being engaged in a circuit. You have to measure them by themselves, outside of the circuit.

Anyone with electronics knowledge can shed some light?

 

[Killrose]

those caps are bad. Try replcing the bad ones only or all if you can get them. Could be another component gone bad that took them out though.

 

[psolord]

Ah I see. That's actually good to know, since there could still be hope. Thanks.

Now regarding these codes on the capacitors,

ULR
270
16V
zm

I don't know what ulr is but I guess UL stands for Ultra Low something?

270 should be the capacitors ... erm... capacity? And is measured in μF micro Farad and not uF as ebay sellers state?

16V is the voltage obviously.

And zm beats me what it means.

So will these do?

Also judging by the coloring on top, I guess the side that has the color is the negative? In any case I will have to install the new ones exactly how the old ones were, so I get the voltages right, correct?

Is there a point getting capacitors with a little higher μF rating? Will they be more robust or will they make the circuit unstable?

I think your caps are blown. Even before reading your description, that's the first thing I looked at. That's one of the dangers of baking your card. If going to 210*C, you should have covered the caps with some aluminum foil.

I think you should just move on. A used 7950/7970 will crush the 570 1.28GB and are dirt cheap. Heck, a 750 will be about as fast as a GTX570. Since the 570 was in the 5850 CF Q9550 rig, you could just sell your 5850s and get a GTX950 2GB as that would probably be an upgrade or try to hunt down a used GTX670/680 if you want to use PhysX on that rig or something (i.e., why else did you have a 570 with 5850s? or was it just to show that the rig used interchangeable GPUs?) This is a sign for you to upgrade by maybe selling those 5850s as they will only struggle even more in 2016 and beyond. Then again that Q9550 CPU is going to become a serious bottleneck in many games so maybe you can just keep that 5850s and not spend any more $ on that old rig.

 

[psolord]

Hey Rus. Thanks for taking the time to post.

Actually my Q9550 is my tertiary rig. I just use it for testing. I am always fascinated seeing new code running on both old and newer hardware.

Same goes for the 5850s and 570. I am not really looking for an upgrade nor a replacement. My next upgrade for the main rig will move all spare parts one rig down anyway, so the Q9550 will be getting my 7950 which is now on rig2. At some point the cpu of the main rig will be upgraded and the same hardware reallocation will take place. Been doing that for years. Many do. Justifies the cost of an upgrade even more, because when you upgrade the main rig, you upgrade all the rest as well, lol.

Also, it has now become a challenge. To see if I can fix it. I like to try and fix broken things and to explore previously unexplored waters.

The capacitors were like that before the baking though.

Makes sense.

The capacitors were like that before the baking though.

That's probably why baking didn't work then - the card was dead. Notice how those capacitors are bulging?

"If you were to open up a capacitor you would find thin sheets of paper and metal rolled up together. The entire assembly is then wetted with an aqueous electrolyte solution. However, if the formula is not correctly mixed up, hydrogen gas can apparently build up in the aluminum can with time. The gas causes the hermetically sealed aluminum cans to burst, or partially blow out the rubber end cap. If electrolytic capacitors "dry out" they won't work properly, and that can cause problems with the computer which can be very difficult to figure out."

Your caps just haven't fully burst at the top but the symptoms are there:

7600GT

Can you take higher quality pictures of the entire PCB front and back? You might see leaked electrolyte.

It's actually technically possible to replace the capacitors but I am not sure if it's worth the effort.

 

[psolord]

Awesome thanks.

Well as I said, for me it's worth it if I manage to get it back on line. If not, I will turn the GF110 into a key chain!

I will try to upload some better pics in morning light once I reopen it again.

If capacitors weren't little bumped up before baking that means you overbaked your graphic card. It they were there all the time then it is time that you change them.

Do a lot of praying... Also toss it in the oven for 5 minutes.
