Hello guys. This is not a joke, since the 1st of April is some days in the future still. This story starts off with me having alot of issues with my ~4 year old Powercolor HD4870x2. Some months ago, I started having issues such as computer not receiving any video signal when booting and strange green checkered artifacts all of the screen requireing a reboot. I was especially experiencing issues with hardware accelerated video like flash. These issues where quite sporadic and never while gaming. Gaming still worked like it should. However the issues became more and more frequent, until one day, when I could not even start a game because the screen would hang, and only 1 out of 10 boot ups where successful without any artifacts. The successful boots almost always ended up in the green checkered screen as soon as i went to youtube, or for that matter gamespot or any other video heavy web site. To say the least I was beginning to tire of rebooting my computer, so after researching, I found that this was a common issue after some years with these cards, and I just basically had to resign myself to the idea that my card was dying. The horror! :behead: Basically some of the memory modules become bad after being heated and cooled for a long time, or something like that. I switched the card out for my old X1950XT that was still working like a charm. And then the same day that I switched the card, I got an invite for the Diablo 3 beta. I played it, and it worked, but I want my bells and whistles dammit, so after checking Toms Hardware (in researching what new card to buy) I found that my old card is still pretty high on their hierarchy chart. I have always been that kind of guy that never gives up and always, always looks for one more way to solve something, so I started searching for ways of maybe repairing the card, or if someone knew a way to split it via software to one card or basically ANYTHING else than discarding it and buying a new one. What I found was this: http://www.overclockers.com/forums/showthread.php?t=606658 and this: http://forums.electronicarts.co.uk/members-helping-members/1394250-4870x2-died.html aaaaaaand this: http://hardforum.com/showthread.php?t=1421792&page=2 You get the gist, right? For those of you that don't want to read the links, these are success stories of people stripping their out of warranty graphics card of everything except the card, then baking it in the oven for 180 - 220 degrees celsius for 7-9 minutes and then letting it cool down, applying new thermal paste and then - Voila! A working, non artifacting graphics card. Basically something that I had never seen here on Guru 3d, and this is my main forum for all things graphical. Since the card was now a very expensive paperweight sitting on my desktop, I figured that I don't have anything to loose, so I stripped it of the cooler, cleaned all the thermal -grease and -goo from it, and then put it in the, preheated to 200C, oven GPU side facing up, standing on three small mounts of aluminum foil, placed carefully so as not to touch anything sensitive, for 8 minutes. Some of the longest 8 minutes of my life so far. I then let it cool for half an hour in the oven with the door open, then for 15 minutes outside the oven. Then I cleaned the cooling blocks under running water, let them dry, applied new thermal goo (had some Arctic Silver 5 left from earlier adventures) And put everything together again. Held my breath, and in to the computer it went. Still held my breath and turned the power on. Still holding my breath as windows booted up, FIRST TRY!. WTF?! It worked! :3eyes::3eyes::3eyes: Don't get your hopes up, might just be a fluke, it worked 1 out of 10 times earlier, remember? Okay, so let's try this. Start up skyrim, works perfectly, start up Crysis 2, works perfect.... hmm, some strange artifacts, no these are driver/texture related. I remember these from earlier, phew! Start up Mass Effect 2, works perfectly, leave it on for 10 minutes while I go take a dump and shut up that nervous tummy of mine. Still running!!!!! To say the least, I am happy, elated even that I got my 3990 SEK (599$ todays exchange rate) graphics card working again by baking it in the oven. The theory behind this is that these cards get so warm and then cool down so often and to such extremes that the solder get tiny micro fractures that the eye can't really see, but they interrupt the electrical pathways. One other theory is that whiskers grow ever so slowly from the solderings. The xbox 360 has seen alot of these issues, and the 8800 from nvidia aswell. http://en.wikipedia.org/wiki/Whisker_(metallurgy) The oven baking is basically making the solder liquid again so that it can, via surface tension, blob up and reflow itself to the correct configuration. This apparently solves the tin whiskers aswell. People have been baking their Xbox 360's by wrapping them in towels and disconnecting the fan to solve the red ring of death, which apparently reflows the solder aswell. Now, I did this yesterday, and so far so good. I have no idea though how long this will last. One dude (see links above) writes that he began having issues again after 7 months, and did this again to much success. Apprantely he has done it 3 times in total, when issues started appearing again, and it has worked every time. Im just so glad that I may now be able to keep this card still when I get my new equiptment (new Cpu, new Mobo, new rams and an SSD) yeah baby! I wish you all the best, I will write here again if it stops working, then I might do the oven trick again and take some pictures aswell. TL : DR I baked my 4870x2 in the oven at 200C 8 minutes, and it works wonders again. Peace out.
