Both my cards have some coil whine even when i use them one at the time, even if i connect 2x 30A capable current lines from my 1250w PSU on a single card, I can distinguish the noise only because the pc is on my desk at ~ 50cm away and only if i keep the fans at 20% and run eg Heaven benchmark. The noise is more high pitched the time you click to exit heaven for a second or two, during the transit from 99% 3d operation to low 2d clocks.

I suppose that this is the case with all 7970 up to a level and is more obvious if you watercool the cards.

@Levesque
The only thing that has made me wondering, is that Levesque who has 4 watercooled cards has reported in a forum that only one makes this noise?!
Having that in mind, i checked both my cards (initally i thought i had a problematic one) but then i realized its both cards having coil whine!

I got upto 80 degrees on the top card while playing BF3, ambient temps are 33 degrees C.
I tried overclocking both cards by maxing out all sliders in CCC with 20 % power and my screen just goes blank and locks up.The cards are 88 % and 80 % asic quality.Shouldnt I be able to overclock 1125 easily with both cards?

if u got EZ plug (4 pin molex) on mainboard,plug one from PSU to there,to provide more power to cards,at least on mine there is 2 EZ plugs for 2 or more cards,to provide more power what can give u more stability..just option anyway...

With the latest 12.2 prerelease drivers I have some BF3 issues. It keeps in a low power state or something for the first two minutes ingame with like 5-10 fps on my 7970, after that its working fine. Running at stock or oc via CCC gives the same results.

I'm trying to find a specific previous driver on the support.amd.com site, but I can not find any history of betas/release candidates or something. I'm looking for this cause I'm not exactly sure which was my previous driver, a RC or something else.

Does anyone know how to find an overview of all released drivers on support.amd.com, RC´s included?

I tried 12.2 driver for my 7970 and it keeps downclocking to 501mhz when I game. Anyone else having this problem? I may have to go back to previous driver.

Also, my msi AB does not work. It gives me 0mhz core, so I had to uninstall my msi ab.

Just installed the pre-cert 12.2 (or 12.3 if you believe GPU-z) and CCC no longer appears. I right click desktop, select Catalyst Control Center, and nothing happens.
It never appears, and CCC.exe appears for less than a second in Task Manager, then disappears.

Just installed a EK Acetal/copper block on mine today and the temps are insane. I'm running eyefinity and the temps on stock cooler were 50c idle 45% fan and 77c load 60% fan. Now idle is around 28c and load with furmark is 42c. Games are playing at 32-35c and I'm running 1125/1500 @ 1.174v biggrin.gif

Edit the HD7970 Bios with a Hexeditor:

y28jrkjh8ull.png

GPU clock
RAM clock
GPU voltage

You have to reverse the value and change the hex to decimal.

Examples:

hex: 54 69 01 -> 01 69 54 -> dec: 92500 = 925 MHz GPU clock.
To change 2D GPU voltage from 0,85V to 0,8V (Lower is not supported) hex= 52 03 to 20 03

To save electricity I prefer to change all my clockstates to 300/150MHz and 0,8V (30 75 00 98 3A 00 20 03) and use a 3D profile for Games.
This works only with Asus GPU-Tweak.

How-to:

- First flash the Asus bios.
- Make a 3D-Profile with Overclocking range enhancement and Kepp setting for the next start
- Flash the modified Asus bios, reboot
- Disable Overclocking range enhancement and Kepp setting for the next start and enable Overclocking range enhancement again
- Click on default close GPU-Tweak and start it again and click on default
- Disable AMD Overdrive in the driver

Now you can switch between default clocks and 3D:

If you install a new driver, you have to make this all over again.

What's the best program to use to push the card past the 1125/1575 ?? I'd like to go for more now on water with these temps.
