Bake your Graphics Card in the Oven Fix " IT WORKED" - Page 42

post #411 of 746


Add one more success story.

I received an 8800 GT from a guy who had been playing games with the card, but with no fan on the card at all. The story is that someone else tried to clean out a computer with a high powered air hose (designed for filling up car tires) and blew all of the fan blades right off of the fan. That person gave the card to my friend. My friend used it to play games and tried compensating for the missing fan by sticking a case fan underneath the card. That didn't work and damaged the card. My friend gave the card to me. This card showed artifacting right in the BIOS and could not even boot into windows.

As the card was trash anyway, I disassembled it. Just in case the "oven-trick" actually worked I wanted the fan to be able to cool the card down. Unfortunately, after disassembling the card I found that the 8800 GT fan has a unique design; it fits into the cooler and blows air both toward the card and through the vents. Small fans I have lying around are not the right size and shape. I replaced all of the fan blades by hand with pieces of zip-tie cut to the same length as the original blades. Attached them with bonding glue.

I then baked the video card in the oven for 8 minutes at 380 degrees. I let it cool off for 30 minutes, reassembled it, and tried it out. It showed no artifacting and booted right into windows. First I tried Titan Quest, then I tried Crysis. So far, no problems. The only issue is that the repaired fan does not work as well as it did originally as the new blades are heavier and create more drag. I have to turn the fan up to 100 percent to get the card to idle at 45 - 47 C. However, as I've found from reading articles online, the original fan was not much better.

However, if anyone has a dead 8800 GT / 9800 GT reference card with the fan in tact... I'd be interested in the fan alone.

I'm going to leave the card in a system and I will leave that system on for a few days, just to see if it lasts.

last year I baked an Asus Dark Knight GTS-250 that died on me.

I bought it used and it died in a couple weeks...this was a card direct from Asus and the Rep gave me an RMA to get the card fixed.

I got bored and backed the card at 400degrees for 10 minutes but left it in the overn while it was cooling down for another 10 with the door cracked...it works fine

I told the rep what I did to fix the card and he laughed and offered to RMA it anyways...I havent done it

A buddy of mine had the same card and I tried to bake that one and it did not work after the baking and that was to the letter of 385 at 10 minutes....

I RMAd that one and got a better card....sweet deal

I am for trying anything to help cut cost on shipping and time loss without the card and even helping cut cost of RMAs by fixing it myself if I can

To state the obvious, it would seem reasonable to assume that a combination of design fault and high temperatures caused the initial micro-fractures that ruined this card the first time. One would discern that after being repaired it would then be even more sensitive to developing micro-fractures due to temperature than it was initially.

So, one would need to lower the temperatures (both load and idle) so that the card is not often heating up, then cooling down. For example, using Rivatuner (or a BIOS hack) to force the fans to run at 100 percent at all times. Otherwise, if the temperature is not addressed, one would predict that the card would fail again.

It would be reasonable to assume that any cards repaired through this process should be treated as though the cards are more sensitive to temperature fluctuation than what is officially suggested for reference temperatures.

This may have already been covered in this thread, I certainly didn't read the whole thing. Two things come to mind.

1. To the OP... I have read into this a lot just out of curiosity. Seems really cool to just be able to bake your card and its fixed. The only thing is, from what I have read, many times they still die again a few months later. Sometimes they do, sometimes they don't. Might be worth it to sell the card and use the money to put towards a newer card with a warranty. Seeing as how its hit and miss when it comes to the long term effectiveness of this method.

2. Unrelated, but does it seem to anyone else like they need to improve their soldering methods if this is something that people are doing to fix their cards? I mean what are they selling us? Some kind of cheap junk? You hear about this kind of thing all the time. Every time I read through the forums, somebody has had their card die, and they are looking into some way to fix it. Perhaps the manufacturers need to stop being cheap and come up with some higher quality solder.

Although this trick fixes solder connections, it may also weaken the solder in general, making the cards susceptible to failure. Any sudden variation in temperature could cause a problem. To avoid such a failure, one would want to keep the temperatures on idle and on load as close to being the same as possible so that the material is not expanding and contracting very much. It is the expansion and contraction that will lead to micro-fractures. I believe if one could do that, a repaired card would probably not fail that soon.

It would seem reasonable that cards that fail after being repaired do this because some people go on using the cards in exactly the same way that they did before, not realizing that the card is more susceptible to damage. If they don't address the temperature issue, more micro-fractures will undoubtedly occur.

WOW...old thread is old...

BUT IT'S AMAZING.

I wonder; has anyone had a GTX500 crap out on them?
Have you tried BAKING IT?

JvF's tutorial is sound, even if not within the bounds of scientific research. Solder is low grade metal, good enough to conduct the juice, but i wouldnt make a closet hanger out of it. It melts quickly, and given if the card is even, the component should set evenly into the softened/melted solder. The only part i would be wary of is if there is some stray solder that crosses a circuit on the PCB. That would be dire.

And another success story!

My 8600GT died on be shortly before Christmas. My PC wouldn't boot at all and just restart over and over. Today I was looking to buy another card, but I decided to try one more time for a fix of some kind. I found a forum elsewhere that mentioned "microwaving" and I thought, "What? Are you serious..?" That led me here, ovening (if that's a word) it! I was skeptic at first, but what did I have to lose? It was the longest 5min of my life, but after putting everything back together.. it worked. My graphics card is alive and kicking once more! THANK YOU!!

If it fails again anytime soon, then that's cool. I had another chance with my card and I'll make every second worth it. =D

IT'S ALIVE!

A week ago I purchased a 9800 GX2 that had severe artifacts and screen tearing wondering if this would work. It was $30 including shipping and I figured I could just resell the card for about the same if I couldn't fix it.

So I plug the card in a right away I see artifacts on the bios screen, after that I saw random characters on the screen and then windows loaded. I tried installing the driver but that just caused the screen to go black and lock up the pc.

Determined to get it working, I pull out my baking sheet and preheated the oven at 400F. I disassembled the card and popped it in the oven. 10 Minutes later I pulled the card out and then let it cool for a half hour or so. After it cooled I reassembled it and shoved it back into my computer. It felt like forever waiting for the post screen (it was only 3 seconds) but it did post and I saw no artifacts, not a single one! Once in Windows I installed the latest Nvidia drivers (266.58), they installed but my screen didn't change or anything, so I rebooted and as my desktop was loading my second monitor clicked on... The drivers loaded just fine. Now I'm really excited so I fired up ATITools to check for artifacts... I didn't see a single one for the 10 minutes I ran it.

I played Modern Warfare 2 for about an hour, the gameplay was so smooth.

I'm still in disbelief that this card is working, I'll update in a week to confirm that baking worked but so far so good.

I thought it was supposed to be 10 minutes at 350f?
