XFX Radeon HD6950 Unlocked

Recently been reading about how the Radeon 6950 can be shader unlocked to become a full fledged 6970. Taking advantage of boxing week savings, I managed to snag an XFX 6950 at a nice price. Unfortunately it came on NYE (Happy New Year!) and I didn’t get a chance to play with it until today.


I’m upgrading from a non-reference XFX Radeon HD5850 which overclocked like a champ for the one or two months that I owned it.

Following the steps found over at TechPowerUp’s AMD Radeon HD 6950 to HD 6970 Mod page, I proceeded to flash it using the XFX HD6970 BIOS also found on their site.

Look below for lots of pics!

And here we go unlocked!

Make sure to set your PowerTune in CCC up to +20% to unlock the full benefits!

Here is a quick comparison for 5850 vs 6950@6970 in Unigine

Buy up these cards before AMD’s new revision removes this unlock!

10.6.5 Update

I’m a few days behind, but finally got my HackPro 4.1 updated to 10.6.5!


My setup is pretty simple, so the only steps required were:

1. Update to 10.6.5
2. Roll back AppleHDA.Kext to 10.6.2 to fix sound and sleep
3. Install i3 update for System Profiler.

I used MultiBeast 2.4.1 for steps 2+3.

Everything’s working well, and I also installed the “Jailbroken” USB3 drivers that Cartri has so kindly hosted.

Recently sold my HD5870, so I’ve switched my main computer over to a HD5770. It works quite nicely using Kabyl’s boot loader. Also purchased a cheap $10 Mini DisplayPort->VGA adapter and it works quite nicely!

HD5870 + OSX + 3 Displays

Finally able to get my Radeon HD5870 1GB working with my HackPro 4.1.

After using netkas’s 5870 hack, a few guys over at InsanelyMac got it working using an ATI ROM and new boot loader.

No more issues with 2560×1600 requiring the display to sleep before it works. Also, all three monitors are working as well! 2 x DVI + 1 x DisplayPort to DVI (using an active adapter).
Steps are as follows (replicated from the InsanelyMac post):

1. Install all kext’s found on netkas’s post, EXCLUDING ATY_init.kext
2. Grab your ATI ROM and stick it in /Extras, naming it properly
3. Install the new boot7 loader
4. Boot with flags UseAtiRom=Yes GraphicsEnabler=Yes
