thank you guys.
I installed msi afterbuner2.2beta11, lowered memory clock to 685hz, voltage to 1062mv
the temperature dropped to 72C at fan speed 50%(~3000rpm)

I just noticed that the real mem clock is still 1375!
but I'm happy with the hashrate and temperature,and the cost of power(about 285watt in total, 95watt when idle),
I won't bother to tune it any more.

As I said...

It will take a new kernel to work.

Specifically I suspect you'd need to disable bfi int patching and play with vectors and worksize

Probably in ocl.c this line 320:
clState->hasBitAlign = patchbfi = 1;
would need to become:
clState->hasBitAlign = 1;

Then you'd need to start with something like -v 1 -w 64

To do this cleanly I'd need to play with the hardware myself to detect if/when it should do this and so on... and I don't.

just tried with cgminer on win7. it started the cards, but I did not get any accepted shares and the mhash was at about 150. for about 30 seconds, then I stopped.

does anyone know if this will work with:

linuxcoin and cgminer ?

cgminer has no support for 79xx yet.

I tried to lower down the memory clock, but it seems can not be controled,
no matter what value I set, the result are always 1375

Until you can lower memory, at least allow the fan to run to help kool that card.... your above 80C, no telling what the vrm is at?

Check the 3*7970 thread, you have to use MSI AB with unofficial overclocking set to 2 to be able to lower mem clock < bios limits, so far haven't found a way to do it on linux. :/

I finally intalled the card in a win7_x64 box.
at 50% fan speed, it is a little noisy, and the temperature is a little high.

Well, your memory is still high, so that could account for the high temps... little more fan speed couldn't hurt

OP, is that a dedicated mining rig? Try running /usr/bin/xinit instead of /usr/bin/X, k?

thank you.
my xorg.conf is exactly the same as yours. when I execute "startx", I saw a green message "unsupport device ....." on the bottom-right conner, but the message only stayed 1-2 seconds, and the screen turn to black. A process /usr/bin/X is running, and occupied 100% cpu.
what is your kenel version and x11-server version?

by big fat overlay I mean you constantly have a greenish-transparent text in the bottom right screen corner that says "Unsupported Device"
xorg.conf is just your basic ati xorg.conf, haven't bothered trying to get multihead support working in linux on that box

Code:

Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Module"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"
EndSection

Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
Monitor "aticonfig-Monitor[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

with 11.12 (and the 12.1 in the ocl1.2 dev preview) aticonfig doesn't recognize it.
manually edit xorg.conf and the card works (with a fat "unsupported device" overlay).
atitweak can be used to check temp/set clocks/set fanspeed/...
diablo and phoenix work.

edit: "device 6798" = your lspci doesn't have it in it's database yet and shows the hex PCI device ID. same here.

thank you for the information.
what is "a fat "unsupported device" overlay", is it a configuration in xorg.conf file?
would you please post your xorg.conf file? thanks

Well linux identify the device as a 6798 is not a good sign.

Likely some patch is needed.

I just bought a HIS7970 card, and I can't make it work on my centos6/fedora16 box.
I installed catalyst11.12 driver, which is the most recent linux driver I found from AMD's website,
aticonfig report "No supported adapters detected"
while "lspci|grep -i vga" shows: 01:00.0 VGA compatible controller: ATI Technologies Inc Device 6798

the mb is a ASUS-Z68, a 6850 works normal on it.
any hints?
