If a GTX 465 has 8 memory chips on it, then it is not a GTX 470 and therefore it will not accept a GTX 470's BIOS. In other words, if a GTX 465 has 8 memory chips, then it is not "unlockable".
But even if it has 10 memory chips, the GPU itself still has to be a true GTX 470. Fortunately, the vast majority of these Golden Edition cards have a true GTX 470's GPU on the card in addition to the 10 memory chips.
The heart of my question is still hanging. If MSI bins these 470 boards because something specific doesn't meet their specs, how does flashing it to a 465 make it work all the sudden.
I have figured out another way to state part of my question:
It's like having 4x2GB sticks of RAM in your computer, but say Windows only needs 1.5GB to run. What tells Windows what ram to use? Does it use part of the RAM from each stick? Does it max out one stick beore spilling over to using some of the next one?
That's where my "but what if 2 of the 10 memory chips were sub-par" thought came from. If MSI realized what specific hardware was bad, they could somehow lock it down. Then we're unlocking it and using it.
But if it's not a specific piece of the board that's wonky, then how does binning it and making it a 465 all the sudden make it work? If the hardware was too crappy to work as a 470, I guess I'm amazed that it somehow functions well as a 465.
To use a car anology: An engine with a bad piston is going to be a bad engine regardless of it being in a Ferrari or a Toyota.
Makes it seem like the overall output is what MSI was aiming for. If the goal for a Ferrari engine is 400hp, and they make a batch of engines that only make 200hp... and the standard engine for Toyotas is only 200hp... it seems kinda crappy to sell a bad engine under a different name just because it meets some of the specs. A bad engine is still a bad engine.
So it makes me wonder why they would sell a binned 470 as a 465 given that the hardware still has something wrong with it unless they completely isolate and bypass the broken part. And that's where my BIOS theory came in. It seems like they'd have to do something specific to bypass the sub-par part of the card so that it functions 100% as a 465 without a chance of failure.
