DIY video card repair geforce 9800 gt

In detail: do-it-yourself video card repair geforce 9800 gt from a real wizard for the site my.housecope.com.

Only in my BIOS it showed 2.4 GHz by default instead of my 1.8 (percentE4300) I changed nothing more in the settings, the computer worked for 2 days and died vidyuha

Help me please.
P.s Vidyukha took second-hand.

APMxxxxx change ALL to analogs (by datasheets).
The short circuit can be determined by unsoldering (lifting one leg) the choke in the corresponding circuit (core, memory.).
You measure from both ends and determine the chip or the stable one flew out (in your case, it's more likely a stable one).
From the side of the chip, the resistance will be small (units of ohms), so do not be alarmed

The device needs to be able to measure the difference of 1 ohm

dima644 thanks for the feedback on my problem. On the board I see 4 chokes in total, 1 to a stable, 2 on the shoulders of a stable which are combined into one point there and here the short circuit. , but on both of its outputs at 55 ohms relative to the ground. And on the chip of the vidyuhi in the corner where the key has contacts in the form of the letter G, + is drawn next to them, can this be + the power supply of the chip? If so, then I measured there and seemed to be 1 ohm, although I did not solder anything during the measurement, except for the above-written security officials and 2x throttles after them.

The device needs to be able to measure the difference of 1 ohm.
The DT9208A multimeter will go, I think

Strange, to put it mildly, repair method.

TE,
Well, since the computer is cut down by the protection when the vidyuhe is inserted, it is necessary to dig the feed. On switching on without additional power supply
not said. I also draw conclusions. And how to look - he explained on his fingers. They will sound something - look and tell you more specifically

alximik77,
I would have posted a photo or something (a feeder in the sense). sounded the shim, I would have checked the small-omniki in the locks, even if the field workers were SI.
Without add. power supply (6-pin connector, or several) the computer turns on?

dima644, your advice is correct, I'm talking about the author. Did he determine exactly that the video card is short or is his power supply dying? And what about the mention of overclocking?

Video (click to play).

To the heap.
Although we do not know what kind of mother was there, she could pull the frequencies of the vidyuhi up.

this conder soldered the measurements on the board with the same short circuit. Tell me what else you can check, I don’t want to think that the chip is.

There is a memory mikruhi near each mikruhi, I don’t know how to name the type correctly, I measured the control points of chtoli, one point seems to be 0, the other 51, and so next to each mikruhi. I checked the remaining transistors like norms. What looks like a short circuit on a chip, right? I don't want to realize it.

First, 2 transistors in a pair stabilize the 12V power supply for 4 power transistors, the voltage is not more than 2.5V from which the percent of the vidyuhi is fed, and then the memory power supply stabilizer is also from there.

GPU power choke - in the middle photo in the center (large brick in ferrite)

GPU power choke - in the middle photo in the center (a large brick in a ferrite)? but for some reason it seems to me that it was a memory driller that determined along the tracks, next to 2 transistors from the gates of the road lead to the RT9259 stabilizer, and another mikruha is RT8802A (as a voltage controller on the GPU, as the search suggested)

What quality pictures I posted - this quality and the answer (chose the largest choke).
If you could find datasheets for shims, then it will not be difficult for you to find a malfunction according to typical schemes.

dima644 tell me, but this shim itself can give a short circuit to RT8802.
GPU power chokes are most likely 2, I just dropped them here is a photo

Thank you, dima644 for your help. The problem was solved by replacing all of the above power transistors with analogs. But about the resistance between + and - 1 ohm, it’s probably a working one, for a voltage of 1.0-1.5 volts VPU / this misled me.

You're welcome.
If I were you, I would also replace the condenders (ALL electrolytes) with the following denomination (both in terms of capacity and in terms of spacing).
For example, there was 330.0x10v stavish 470.0x16v.

Spasobo, I will replace it at the first opportunity for advice. The main thing is vidyuha plowing.

Thank you.
ZY it seemed to me or instead of the word "microprocessor" I needed to use the word "timer" (?)

Hello. I ask for all possible help in the selection of analogs of 2 types of variable resistors, as well as a push-button switch with latching.
1) Variable 50kv 8 feet, dimensions are given on a compass
2) Variable 20kv 6 feet, dimensions are given on a compass
3) Pushbutton switch with fixation of 6 legs, dimensions are given on a compass
All components were soldered from the board from an old speaker made in Taiwan.
Perhaps someone has come across similar components and will be able to tell where to get similar ones or a good replacement of the same size.
Thanks in advance.

The crux of the matter is that I want to make an interesting homemade product for a hookah, namely "electric coal", a nichrome thread for a vape is used as heating elements, this business will be switched on from 12 volts at home from a computer power supply, and in nature from a car battery, too 12 volts, 40 cm of a thread from 12 volts starts to blush not badly (which is what you need for vaping), uses 1 thread somewhere 3.4-3.8 amperes, a thread section of 0.511 mm (there may be 2 threads)
The main question is what you need to make a power regulator to smoothly change the filament filament using an adjustable resistor, and some kind of powerful transistor, the current that is needed is quite large
I would like some kind of schematic, an example of a resistor and a transistor

What happens if the only cooler fails at maximum gtx 1080 load?

overheating - will drive the board - chip blade

Warming up the card is not a repair, and it should be heated correctly, not with a hairdryer, but with an IR station, if the solder has melted under the process, then the percentage should be slightly shaken so that new balls form. And THIS is all a dead poultice

Well, maybe everything is correct, but the helium flux is not right! Liquid you need!

Why be silent? We are not deaf.

what did you put on the sides tell

Inno3D GTX 650 Ti 1 gb I start the computer, the power supply does not start and there is no sound squeak. I turn off the power of the wires to the video card, the computer starts up and the cooler on the video card quickly turns. But there is no image on the monitor. What is the breakdown?

POWER SHORT CIRCUIT IN THE CARD, THEREFORE THE POWER SUPPLY UNIT IS PROTECTED

Video for the deaf and dumb. It is necessary to talk with the people!

And what to do if the card heats up quickly. After 20 minutes of work, practically without load (only the browser works) does the temperature reach 115 degrees? The video card is the same. The fan on it turns somewhere up to 90 - 95 degrees. Then it is cut down, apparently from overheating.

This is not a renovation, regardless of the outcome.

It is clear that this is not for a long time and very much depends on the degree and duration of the load, does someone still consider heating the crystal as repair ?!

What flux (would you show on video or write)? How long did they warm up?

+ ilya ilyin Martin flux or other high quality no-clean! creep until the chip starts to rock

Well, yes! If there was a micro-crack in the ball on the substrate itself, then such a repair will help, but if the blade is under a small crystal, then this is for a few days, max a week

Low-power vidyahs live long after warming up

May God grant her a long life and not get sick 🙂

Svyatoslav, why are you heating the card on a metal sheet? so that it dissipates heat and increase the frying time?

Good day to all.
I ran into a problem on my video card, and I don’t know what to do, or throw this one away and go buy a new one, which I really don’t want to do since the video card is only 1.5 years old, the warranty was for 1 year.
Maybe you can help me.
The problem is this is the simplest screen with Windows 7

Here is such a ripple, although the Windows are only fresh, I'm sitting now with XP everything is fine, but as soon as I put on a demanding game with good graphics and everything starts the same ripples when I play, I want to ask you for some advice on what to do.
I took it apart, took off the radiator and saw dried thermal grease, maybe because of this it gets warm and gives out such garbage. The Drava are the last.

The term paste has now changed the temperature of the vidyuhi in idle 44 C, here's what I saw when I entered from windows 7

and he constantly restores them.

I have the same symptom, but it only occurs in games.

The computer was bought in May, until the beginning of August everything was perfect. Once, while playing Starcraft II (on the cutscene), the entire screen was covered with multi-colored interference, after exiting the game using Alt-F4, the entire desktop was in such ripples as in the screenshot in the first post. After the reboot, everything seemed to be back to normal.

A few days later, Fallout 3 crashed with the error "Video driver stopped responding and was restored", ripples appeared on the desktop again.

After that, the games began to crash with might and main with a blue screen or show artifacts, if you try to exit the game at the same time, ripples remained on the desktop. In 2D applications, a video driver error message occasionally appeared, i.e. artifacts only started in games.

He took the computer for repair, the next day they said that the video card had broken down and replaced it under warranty (in my presence, i.e. they could not leave the old one by mistake).

Day somewhere everything was fine, and suddenly, while playing Stalker, the computer lagged and ripples appeared!

Then the whole day I played different games, 3dmark, krayzis benchmarks, but it was not possible to cause ripples again. The memory stress test produces exactly the same log as in the previous post.

DIY modding - modding alexgo

In this post I want to talk about my experience roasting (warming up) video cards, as well as unsuccessful examples of roasting video cards by other people. I repeat once again that everything is based on personal experience. Therefore, my assumptions and conclusions may be wrong. Nevertheless, almost all the video cards that I have warmed up work to this day.

This entry is not a guide to action. I, as an author, do not bear any responsibility for the damage to your "hardware" by your own stupidity or as a result of crooked hands.

So why do video cards warm up? Video cards warm up when a video chip or memory chips have fallen off. It fell off not in the sense that it fell off the board (from the PCB), but in the fact that contact disappeared at some points between the chip and the board.

Why is this happening? Here I cannot give an exact answer, but I can only assume that chips or memory (much less often) fall off the board as a result of prolonged exposure to high temperatures. And also, perhaps, due to the relatively sharp temperature changes "hot-cold-hot". One way or another, the connection between the contact on the chip and the contact on the board disappears. The solder balls remain either on the chip or on the board. Multiple contacts not working and causing video cards to malfunction.

As a rule, this is found in "hot" (ie, with high heat dissipation) video cards and usually appears after a year or two of using the video card. For example, the well-known series of video cards GeForce 8800GTSGTX (both on the first "hot" G80 chip, and on the subsequent "colder" ones). But in my practice there were also colder video cards, for example, nVidia GeForce 6600GT, GeForce 8600GT, Radeon x1600Pro.

What are the symptoms of a chip "dump" (loss of contact)? The symptoms are as follows: artifacts - vertical colored stripes on the screen, colored porridge (a mess, as some call it). Also, several times the following was encountered: without the installed drivers, the picture was displayed normally, with the installation of the drivers, either there were artifacts, or the system went into BSOD ("blue screen of death").

(Sample photos were taken in this entry .)

How to treat such an ailment? Here, in fact, we come to the most important thing - roasting a video card.

I will first talk about unsuccessful other people's examples frying video cards. So the most common way to warm up video cards is roasting in the oven... Yes, in the oven of an ordinary gas (or electric) stove. This method is very popular, probably thanks to the resource from his Personal pages , where you can find examples of warming up video cards. It is not for nothing that I singled out this method in unsuccessful examples. I find roasting graphics cards in the oven a bad way.

Why bad, you ask. Because in this case the whole video card warms up, i.e. the impact goes to all components of the video card. Which I consider not acceptable. The simplest thing that can happen is the elements made of plastic melt. For example video connectors DVI, VGA and others, as well as power connectors. Naive users believe that if they wrap these elements in foil, it will save them from melting. As practice shows, this is not the case. Whether they are wrapped in foil or not, they will melt, since the video card will warm up evenly in the oven, the foil will only slow down this process. But slightly melted connectors are not a problem. Problems can arise when other elements of the video card overheat - various electronic components whose maximum allowable temperature is much lower than the temperature of the chip warming up. They will simply fail and we will finally add the video card.

Based on these facts, we can make some conclusions... Namely:

Warming up of the video card must be spot-on, i.e. only the chip and memory microcircuits should warm up, and not the entire board as a whole.
The temperature, in my experience, should not exceed 220 degrees Celsius to warm up the chip.
Warming up must be carried out evenly, it is highly desirable with a gradual increase in the heating temperature.
The warm-up time should not exceed 5 minutes for a relatively fast heating and 10 minutes for a smoother one.
The video card should cool down smoothly, there is no need to blow over it additionally.
During and after frying, it is highly advisable not to displace, move, or shake the video card. Otherwise, as a result of these actions, small components located near the chip may move or fall off, since the solder is melted.

Now about my experience in frying video cards. When I first decided to "repair" video cards in this way, I immediately gave up roasting in the oven. And in the absence of special tools, he did it over the burner (ceramic and electric tiles are also used), i.e. over an open fire.

This method has both pluses and huge minuses. The pros are that we can warm up the video card pointwise, smoothly heating and cooling. Cons - open fire, the possibility of darkening the video card or burning paper stickers (stickers) glued to the video card. Nevertheless, I worked out a certain warm-up strategy for myself - the video card was 20-25 cm higher than the fire, did not stay in place for a long time (it moved it smoothly, evenly warming up the chip and memory). In this way, many video cards were cured. For example, in my computer the free GF 8800GTS 640Mb still "lives" and works fine (about half a year) in overclocking mode.

My next step towards improving the quality, reliability and safety of repairing video cards by the frying method was the use of a hair dryer... For example, I use a Bosch hair dryer. It is convenient in that it has digital control, has several operating modes and allows you to set the required temperature, as well as the power (speed) of the air flow. Working with a building hairdryer, for repairs, it takes me about three minutes to warm up itself and a few minutes for a smooth natural (without additional blowing) cooling of the video card.

Using a hair dryer is the most optimal way to fry video cards.

You can arrange holivars on the topic of whether it is worth warming up video cards or not. When contacting a service center with similar symptoms for a video card, you will probably be advised to throw it out. I know that the SC masters are categorically against such a "repair". In fact, they are right that having repaired the video card in this way, they will not be able to give any guarantees for the duration of the work.

By the way, about the duration of the video card after frying. Depending on whom at what temperature the video card was warmed up, how long it was warmed up, and the normal operation time of the video card will differ. It can range from several days, weeks, months, up to several years (at best).

Now let's look at a few examples of frying video cards, both successful and unsuccessful.

A good example. My video card is GF 8800GTS 640Mb. In the photo before frying. Unfortunately, there are no photos after roasting, or rather there are, but only the sides with the chip. After frying, nothing melted over the burner, only the stickers that could not be peeled off darkened. The video card had to be fried several times. The last time it was a very long time ago, I can no longer remember. Now the video card is cooled by the SVO, so there are no problems with overheating.

On the Personal pages of Overclockers.ru you can find several examples of roasting such video cards. And almost all of them are made with an oven.

Here's another example roasting the XFX GTX 280 graphics card in the oven ... In principle, the video card worked, but some of the plastic elements were melted.

And then completely unsuccessful example of frying a video card in the oven. Subject Palit 8600gt 256mb sonic +.

As you can see, the person "slightly" overdid it. As a result, he killed the video card. Not only the electrolytic capacitors, but also the solid-state capacitors (which can withstand high temperatures) swell from the video card. The protective frame on the chip around the crystal, DVI connectors, and the fan power connector are also melted.

Not long ago, one person also ditched the excellent 9800GTX + video card. But I told him not to warm up in the oven. Eh, sorry for the vidyushku. Unfortunately there is no photo. Perhaps it will be.

So, everyone decides for himself whether to warm up the video card or not. If you think it's worth it, then I advise you to contact a person with experience who has the right tool in stock.

In addition, I would like to say that for a more efficient, correct roasting, it is necessary to use a liquid flux, which is introduced under the chip.

All the subtleties and nuances in this post are not described, since this is not a guide to action, but an introductory article.

I recommend paying attention to this article about frying video cards .

UPD I recommend reading the article Problems with nVidia chips .

In this article, we will talk about the most common video card malfunctions and how to repair them.

Chipping of a video chip usually occurs during careless mounting / dismounting of the cooling system and almost always leads to the failure of the GPU. In some cases, the video card continues to work with a chip. A video card with a chipped chip is repaired by replacing the chip, but in most cases this service is not in demand due to the high cost of repairs.
Many modern video chips are protected from chipping by a metal shell or edging, but this remains the prerogative of expensive video cards, budget video chips are usually not protected from chipping.

Memory
When a memory chip fails, repair is complicated by the fact that it is almost impossible to determine dead memory. In such cases, you have to replace the microcircuits one by one, or change everything at the same time.

Can be repaired. The exact price of the repair can be said only after the diagnosis. but the prices for repairing the malfunction indicated by you usually vary from 3500 - 5500.

The service address is indicated above.
