Flash 5750 to 5770 ?

[dengyong]

Since Sapphire had a problem with some of their 5770s being released with the wrong bios, giving the card 5750 specs...shouldn't it be possible to flash a 5750 with the 5770 bios, making it a 5770 ?

not possible

[dengyong]

not possible

Why ?

[BETA911]

Because the shaders are laser locked if I'm not mistaken...

[dengyong]

Only the bios locked them on the Sapphire 5770 models that customers found to have 5750 specs.
The fix was to flash a new bios or exchange the card.

[Touche Turtle]

The 5770 cards that were shipped with the wrong BIOS had all 800 stream processors physically intact but the botched BIOS was only using 720 of them.

On 5750's only 720 stream processors are physically intact, the rest are laser locked as Beta911 says, making them physically unusable regardless of the BIOS.

If it was doable, I'm sure we'd have heard about it long before the Sapphire BIOS botchup.

Thanks for the info.

Actually you can flash a 5770 BIOS onto a 5750 card.

I bought a 5750 to do just that.

There was mention of a Powerpoint presentation at Sapphire giving you walk-through on a video card bios flash. I have not done this in years, so I'd like to see that first.
Does anybody know where that thing is?

I already have the new 5770 BIOS, so I just need some direction.

UPDATE: File found!
It's in one of the two downloads.
Large download is the Powerpoint directions
Smaller file is the actual BIOS

yes you can flash it onto your card but it wont unlock the shaders

[GasPipeJimmy]

That's true, the shaders will not magically appear after the BIOS re-flash.
