Guide - Flashing your HD 5750 with a HD 5770 BIOS

[dubbs]

*If this is against any rules then please delete and i apologise*

First of all i take no responsibility to any cards that are broken or anything. The chances of bricking ARE small but there is obviously a chance of this happening.

Your card will also lose its waranty so please only try this if you know what your doing.

I have taken this off a forum and done it myself with good results.

You will need the following:

USB Stick
Files I provided
ATI 5750 (Of Course)

Step 1:
Download these files, and extract them to your desktop.

http://www.sapphiretech.com/global/lib_files/68.rar

Step 2:
Insert your USB Flash Memory, and run HPUSBFW (This is in the rar you just downloaded).
At the device, select your USB Drive
At File System, select FAT32
At Format Options, tick Quick Format, and Create a DOS startup disk, using DOS System Files...
Browse for the folder named "DOS files"

Step 3:
Click Start, and wait it to finish, when done click close.

Step 4:
Download these files, and extract them to your USB Flash drive

Step 5:
Restart your PC, and boot from your Flash Drive.

Step 6:
It will launch in MS DOS, type:

dir VPHD57~1

cd VPHD57~1

flash

Step 7:
Wait... ...and after it is done, restart your PC, and reinstall ATI Drivers. Now you will have the 5770 Bios on your 5750 GPU.

here is some info.

Stock clocks for my 5750 where 700 / 1150.

As you can see now the stock clocks are 860 / 1200.

The overclock i have so far is at 960 / 1340.

Any questions just post them here

Also if it helps i did this with the sapphire HD 5750 1gb.

im not sure if this will work with EVERY 5750 but i dont see why it shouldnt

But we believe! xD

Edit: But wait, who in their right mind is running Vista and paying for it anyway!? 0_o

So this turns a 5750 into a 5770?

 

[wolvers]

No, a 5770 has 800 shaders and that GPUZ shot still says 720.

I'm assuming that it just alters the base clocks and possibly the vcore enabling higher clocks?

I do have a 5770 - but was considering the option of buying one of these and modifying it then running in crossfire... would that work or no idea?

Thanks

5750 would slow down the Crossfire setup. Get a 5770, it's only £110 these days.

I know they are.

I just wanted to know if it was a like for like once the 5750 had been flashed, thus making it a cheaper alternative to crossfiring.

Thanks for your shout though.

A 5750 crossfired with a 5770 won't slow down crossfire at all, in fact the 5750/5770 setup sits exactly in the middle of the 5750 and 5770 setups.

[mrtckane]

if both cards are running the same clocks then it shouldn't slow it down at all..

 

[varkanoid]

you dont need this command

dir VPHD57~1

Step 4 link not working...

Might consider doing this, buy a 5750 flash it then crossfire it with my current one.

Read the review and its not a bad setup really?
