Just bought a sapphire 6450 512mo DD3, did a fresh 10.7.4 install with Multibeast 4.4.0 (Thanks Tony & MacMac), all is ok BUT the card is recognized as 6xxx.
Can't get any framebuffers to load, I have tried all "AtiConfig=", still always generic loaded. :?
Device is 1002 6779. I have CI/QE, GE=yes.

Any advice?

Thank you!

download and install last chameleon from this link

http://www.insanelymac.com/forum/index. ... pic=231075

after that, connect the vga with hdmi cable.. and you'll have a correct framebuffer detection

use GE yes

chameleon will find all the values as you need..

p.s. no fix for dvi issue.. you have to buy an hdmi - dvi cable

Thanks for the info.

I have all 3 outputs working on the modified kext. Does anyone have issues with the graphics being molasses slow after wake (from sleep)?


(This happens with the vanilla kext also.)

Well folks, that's all she wrote. I can confirm now that my HIS 6450 works perfectly with audio as well. Thank you for everyones help. The eventual fix seemed a lot easier than the required learning it took to get there; however, it was a simple connecter type issue with the Pithecia buffer for myself.

Default Buffer:

Personality: Pithecia
ConnectorInfo count in decimal: 3
Disk offset in decimal 500508
0000000 00 04 00 00 04 03 00 00 00 01 00 00 21 03 02 04
0000010 04 00 00 00 14 02 00 00 00 01 00 00 00 00 04 03
0000020 10 00 00 00 10 00 00 00 00 01 00 00 00 00 00 01
0000030

My Bios Decode:

ATOM BIOS Rom:
SubsystemVendorID: 0x1787 SubsystemID: 0x2012
IOBaseAddress: 0x0000
Filename: ST1G01.001
BIOS Bootup Message: CAICOS PRO 1G/64B DDR3 DVI-D/HDMI/VGA 625E/500M

PCI ID: 1002:6779

Encoder [@offset 44249]: INTERNAL_UNIPHY1 (0x20)
i2cid [@offset 44319]: 0x93, OSX senseid: 0x4
Connector at index 1
Type [@offset 44255]: DVI-I (2)
Encoder [@offset 44259]: INTERNAL_UNIPHY (0x1e)
i2cid [@offset 44346]: 0x92, OSX senseid: 0x3

As you can see, the Pithecia buffer lists my first output type incorrectly, should be 00 08 for hdmi. With information from the aforementioned threads, and a little luck, I successfully edited the buffer.


I replaced this:

00 04 00 00 04 03 00 00 00 01 00 00 21 03 02 04

with this:

00 08 00 00 04 02 00 00 00 01 00 00 21 03 02 04


There you have it, made those changes with hex edit, and one reboot later, TA DA... blissful digital audio.

Why all the headache you ask? Well, the no-name radeon buffer that loads with GE=No, gave me great video and audio I thought, just no hardware acceleration. The problems started when I began to notice occasional screen flickers and audio drops. So, hope this does it.

Glad to hear it! For me it wasn't that easy, I had to change transmitter and encoder value, and my sense IDs were wrong... lol

Anyone else try this yet?

This worked for my Diamond HD 6450 1GB!

I have a Gigabyte 6450 1GB, the kind that was on sale on NewEgg for $20 shipped...
I forgot to run Multibeast after I was done installing so I thought i was screwed, but turns out after reading this thread I got it to work on my incomplete Lion install!

UseKernelCache=No PciRoot=1 AtiConfig=Duckweed -v

worked for me OOB (I guess you could say OOB because I haven't installed anything for it in Multibeast).

(by worked I mean I'm getting DVI and HDMI output, not tested VGA, not even making any claims as tohow well it works. And YMMV with the UseKernelCache, its just because i'm using an i5 3570k)

Are you using HDMI, DVI, or VGA?

apologies - edited my post!

but yeah, i ran multibeast and bridgehelper finally (lol) and now it boots with no issues whatsoever. here is what i put in my chameleon.boot.plist:

Kernel flags: darkwake=0 npci=0x2000
AtiConfig: duckweed
PciRoot: 1

that's it! will report back later when i try watching some 1080p video. no vga tested still!

edit: Just tried watching some 1080p 10bit video. Seems to look pretty good! No lagging or anything. I'll try to see how to test CI/QE but everything is pretty smooth so far 8]
