Can you reball a "baked" GPU?

Just wondering. I have an HP DV6 and a 6990m with a baked GPU. Previous owner baked both.

Can't really tell if the 6990m is baked or not. The DV6 however is obviously baked.

 

I don't mind all of those baked (some times quite literary) stuff. I do mind someone trying to sell them afterwards. You can do NOTHING with such GPU, MoBo, whatever. If a GPU fails there are two options - sell it and someone might revive it; or two - bake it and then throw it away when it fails again (some try their luck again, but it's unlikely to work).

With all of this said, the HP MoBo is most likely for the bin, as for the 6990m, a reball might bring it life. It most likely needs a new chip though, and there are NO quality ones. There are plenty of questionable quality and quite the price tag, so not really worth it. So if reball doesn't help - it's for the bin as well.

 

What do you mean by "baked"? Literally?

 

karasahin, yes, in an oven.

 

I'm not convinced about the 6990m part.

Most 6990m's die due to the bad quality solder that AMD used for the BGA grid. This results in people "baking" them to bring them back to life. This usually works if done correctly as the heat makes the solder touch the BGA grid only to die once again. This exact scenario was seen on the Nvidia 8600m-8400m chips. I am convinced that a reball will solve the problem. The chip is in good shape also, and this tells me that it died naturally. There is however slight wear on the green area of the chip (crap, what's it called? the chip is printed on it and then that is printed on the MXM pcb)

As for the HP, the previous owner says he did "bake" it with a heatgun and it worked for a month then stopped. A reball may or may not work. If it does not, a chip replacement might be in. Working 4650 mobility chips are dirt cheap from ebay.

 

The baking only lasts you that much (pun intended). A reball wont do wonders if the chip is dead, trust me on this. If you reball the chip as a preventive measure, that could prolong its life, but if it's failed, only a new one is the solution. Feel free to try, you might get half an year out of it.

 

Wow. That was unexpected

octiceps, I don't understand
