    Im definitely gonna get grilled for this but i have no clue what flashing a graphics card means? i think it means to flash EFI over to the graphics card so you can have a boot screen? am i correct? because i have a gtx 680 mac edition and i think i can save allot of money buy returning and getting a regular 680 or 670.

    flashing = reprogramming flash memory

    flash memory = non-volatile memory

    Grill, grill and grill!!! There, now you have been thoroughly grilled! :)

    "Flashing a graphics card" is just a short-hand way of describing the process of writing an image file (BIOS, UEFI, EFI, Open Firmware, etc.) to the card's own "Flash" memory. Typically something like nVFlash is used to do the deed. The image file holds all kinds of information from ID strings to voltage and timing tables - besides a lot of other stuff too. These image files can be downloaded from the card's flash memory, modified, and written back in order to get the card to behave differently. The image files can also be completely replaced with a different type.

    Typically this is illegal as in order to get the "other type" someone had to steal it! That's theft if you don't happen to own and retain ownership of both cards. To then turn around and sell this stolen property is HIGHLY unethical and prosecutable! Normally such "flashing" or "hacking" is offered for free as a step tutorial where the end user is responsible for obtaining the files in question - hopefully through legal means but often a blind eye is turned at this point because it's an individual typically undertaking a not-for-profit process. You can think this is basically the difference between downloading an MP3 file (from a CD you own or illegally from the internet) for your own use and burning that file to a for-sale CD and selling it. Massive difference!

    I'm more than a little shocked that there's a user here doing just that (selling stolen property) and MacRumors even supplies him with a "Vendor" tag. :eek:

    Anyway, that's basically what flashing is.

    Right, the way the Mac Kernel works it can initialize graphic cards early in the boot process if the card contains an EFI type file in it's flash memory. :)

    He's talking about doing this:

    http://forum.netkas.org/index.php/topic,5709.0.html

    to a regular (non Mac-Edition) GTX680 Graphics Card.

    And I think you guys know that.

    To the OP, from reading your post, it seems you may lack the skills to successfully flash a graphics card. You may just want to retain the one you have if it's working well for you. Also, and this is just my opinion, but folks who return working items that were bought in good faith, sold by the seller in good faith, and were delivered as described should not be returned in order to save a few pennies. It winds up costing all of us money due to increased up retail costs necessitated due to returns being factored into the selling price.

    Yup, but my reply still applies wholly.

    Good point!

    Aside moral dilemmas, flashing brings nothing than benefits to the Mac users world.

    Thanks to people like Arti, nvflash, Gotoh (old days), netkas, MVC (nowadays) people have wider choice, vendors are selling more cards, nobody gets hurt, anyone's children cry etc.

    Hacking usually involves some intellectual property violation, but (as life shows) vendors don't really care as long as it means their income increase. And they sometimes learn from hackers as well.

    I suppose you know I was old friends with Arti, he taught me much.

    The G4 got Core Image cards in it's final days as a result of our teamwork. Arti was able to give the Cube it's final blaze of GPU glory. His work on 5200 and 6200 cards (which I funded) gave the Cube Core Image support, and those are STILL the best overall Cube cards. Applying his methods I was able to create 7800GTX 512 for G5 and 7800GS AGP.

    I have had unoffical contacts from Nvidia. Never suggested any hostility about my work. They were actually curious about number of Macs running their cards. Ebay is full of people selling roms I wrote. Thousands of cards around the world running flawlessly due to solid Nvidia drivers and EFI roms I figured out. (I had some help but ultimately the GTX5xx cards were largely my work)

    I care not a bit for the complaints. I received thank-you emails from more than one employee at BMD for continuing CUDA support when Apple switched to ATI cards. My cards are running in DIT carts all over the world shooting the feature films that appear in cinemas.

    I am happy with the effect I have had on Mac world. In fact I'm proud of it.

    This discussion seems to continue to veer off topic, after numerous attempts to keep this on track.

    Closing.
