HIS 4890 Fan Noise

[Kurumi]

The issue I have is that my video cards don't have proper fan controls. Both cards are running with 100% fan speed and the second card isn't even seen by the system. They both were seen BEFORE I installed the NetKas patch, but not after. I do have dual display working out of both DVI ports. I know that CF does not work in OS X and the OS will just display to four potential monitors.

 

I have two HIS 4890s in CF mode in the following setup:

Intel Core i7 920

Gigabyte EX58-UD4P

12GB DDR3-1600

2x 160GB Hitachi SATA HD

- 1: OS

- 2: Time Machine

2x HIS ATi Radeon HD 4890 (in Slot-1 and Slot-2)

Vanilla install of OS X 10.6.2 with NetKas' QE/CI exotic 10.6.2 patcher installed.

---------------------------------

Not detected hardware in OS X

Adaptec 31205 PCI-E x8 SAS/SATA RAID controller (in Slot-3)

- 2x Seagate 7200.11 750GB HDs

- 4x Fujitsu 36GB 10k SAS HDs

- 2x Samsung 128GB SSDs

 

I have Windows 7 x64 Ultimate running off the SSDs and dual boot works just fine.

 

This is what OS X sees for my graphics:

I have tried to edit the com.apple.Boot.plist to include a BIOS file (both a generic one and one pulled from the video card itself using GPU-Z in Windows.

I have tried using the GraphicsEnabler=Yes switch and that seems to kill the fan noise, but it KPs with the following:

This is my com.apple.Boot.plist config file.

If there is anything else missing, please let me know and I'll try to answer it. I am at a total lost on how to get this working.

Did you resolve this because Im in the same boat! My 2nd XFX 4890 fan is running at 100%

you could try to set modeel ID to macpro4,1 so that applegraphicspowermanagment kext loads.

search agpm in IOreg to confirm

 

would be interesting to see if this works for you.

here the same: 2 x 4890 = 100% fan

[a-money]

im have the same exact problem, using 4890s in crossfire and the fans are going at 100%. however the strange thing is that it doesnt happen when i install or the first time i boot in, the kext files on my bootable usb are the exact same however. the fans kick in after the first OS setup.

 

wtf is going on

[flatfrog]

Same here, two Sapphire 4890 vapor-x cards. Have not found a solution yet....

[xzero012]

Still no solution to this? Experiencing the same thing. 4890 and 4870 crossfire. 4870 is 2nd card, running at 100% fan.

[el lissitzky]

I have 1 4890 but the fan just sits at the slowest speed! Is the fan controlled by a kext or the firmware of the card?
