The GTX580's GPU is different to a GTX480 GPU, maybe that's why it didn't work.

I think some guy at Tom's forums or somewhere else tried it as I remember reading somewhere about someone that tried it, the extra cores were duds and made it unstable to even display the GUI of Windows 7, let alone run a benchmark or a game. If the extra cores had worked on at least 5% of 480s I've no doubt they would have sold them as 580s or "limited edition" 485s or something, it must have been less than 1% so good luck trying, it could well work for all we know, but I personally wouldn't risk it.

I can't find any articles giving proof that it has been lasered off, I do believe it's disabled in the BIOS, but no one has been able to find it though a hex editor.

They disabled it because of the heat, but I guees Nvidia never thought about aftermarket coolers or W/C
No, they didn't disable the cores because of heat, they disabled them because of the low yields they were getting with all of them unlocked - part of the reason why they came to the party so late (6 months after the first HD 5000 cards showed up).

There's been this kind of a thread already on OCN.. http://www.overclock.net/nvidia/927535-can-you-flash-gtx-480-gtx-2.html


The bottom line:

A GTX480 can work with a GTX580 BIOS..

As for 32 shader units,they remain disabled regardless of BIOS..


CHEERS..

CHEERS..

Guees that this thread has now concluded then, it must be disabled by a microcode or something, or on another chip on the PCB
