5 blinks mean systeem board failure, it can be anything, i should reflow the SB also.

Blink codes not as often exact diagnosis

I should send it back, it was certainly not new, you can't trust all the buyers from ic chip out there, reballing can but you have a big chance that the costumers wil come back in a few week or mount.

that's true but most of the times is very close, especially when the ram blink code is right.

I still thinking it has to be something with the Gpu, i know that you replace it, but try to reflow it, maybe it don't make good connection.

Then it has to be something else, do you have a schematic for that, and did you try with others RAM to.
