Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/06 02:55Hello, I have three cards with the fans just spinning but will not post, so I'm offering a cash reward to help me get them going. The cards I have are the 55nm versions of the GeForce GTX 260, GeForce GTX 275 and GeForce GTX 295. And I will be trying every day. I have a working GeForce 8800 GTX with blackops board with X48 chipset and I was thinking the BIOS's are corrupt. Everything seems fine plus fan spin at max speed but no display. I have ordered a PCI card to try and flash the cards but was wondering can I do it with a firmware programmer or is there a way I can do it with my GeForce 8800 GTX anyway? Or is there something else anyone can help with?

Re:Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/06 10:10Okay, so you have several cards that are not working, and what would be very welcome to find some solution is to know how these cards gotten into that state. So first of all did you buy these cards new and by using them they gotten into this state? Or you bought them second hand and you knew they were not working fine, but just bought them to see if you could fix them. Every bit of information is important and then we have to tackle card per card. So can you give us first of all information on how you gotten these cards, which brand they are and how they gotten to this state?

Re:Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/06 16:11Thanks for the reply, I have have got these cards as faulty and looking to fix them for myself. I don't know how they got in this state sorry but I have fix many cards in the past with me rework station but these GeForce cards don't seem to be solder problem so I'm thinking its a bad BIOS. Any help will be appreciated, any tools I need I will buy and will give a good donation for helping me fix them. Thank you!

Re:Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/07 09:21Okay, so at least we know now how you gotten those and do keep in mind that you might not be able to get them working again since you just don't know what the other person has done to these graphics cards, as I don't want to give you false hope as others might give you. Now before can continue, we have to tackle this one by one, and you will have to get us the BIOS's that are currently on these graphics cards for us to check, and keep in mind the GeForce GTX 295 has two BIOS's. So can you get that done? If these cards do bootup, you will to create a bootable DOS media that will backup the BIOS's automatically.

Re:Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/07 21:17Yeah I know but will give it my best to get them going again. I will try reballing if this BIOS stuff don't work out, anyway I have ordered a PCI card to try and get the BIOS from them for you which I'm thinking there is some advice in these forums how to do that. So I will get onto that as soon as this PCI card comes, if that don't work can you get it off a chip with firmware programmer and flash with it? If so I will buy one, thanks as any advice is grateful.

Re:Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/08 08:41Well I have never bought and actually used a firmware programmer, so all that will be new but do know that if the card still does boot and only the screen is blank that something should be feasible even without a PCI card. Now yes, I do still have a PCI card as well, but actually almost never used it as even with a blind backup and some blind flashing we did resolve bad cards, so even that is not something that is really needed, but would make it easier.

Re:Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/08 15:11No the cards don't boot the PC, Windows comes up with error on debug display on motherboard. As soon as I have the PCI card and get the BIOS of these I will get back to you and thanks to the folks who have emailed me, it is very helpful.

Now the best thing would really that these cards do boot the system but you don't see anything even if that means just with plain old DOS operating system. Cause that is what we just need to be able to flash these cards, but of that doesn't work we will have to explain you the tweezer method, which requires somehow some handy person.

Re:Got multiple 55nm based GT200 powered boards who need fix! - 2009/12/08 16:56Okay thank you, but they don't do anything when plugged intop the motherboard, it does not go through boot sequence at all. Would it be worth tryiong this tweezer trick now or waiting till I have the PCI card and see where that goes. Cheers, I can donate some money now if wanted and then some after, if I get them fixed just so you don't feel wasting your time. Plus I'm somehow at a hold till I get my PCI card which should arrive later this week.

For the tweezer method you can already prepare and that is by finding out for each graphics card the actual firmware chip, to know which one it is so we can check the specs and see how the tweezer has to be done. And if you want to donate some money already be our guest, but if it would be wasting our time we wouldn't have made these forums.
