The 7970 Thread. Post your overclocks and experiences here:

Yeah its pretty quiet, guess it may boil down to how your case cooling is, if its decent, so keeps the temp of it down, then the fan doesn't need to spin so fast, as the temp doesn't get to rise so high, that it needs to start going hell for leather

 

Thanks for the valuable info, it's meant for Corsair Graphite 600T with H100 on the CPU + 200mm fan on the front and 120mm on the back, I guess it's more good than bad of an airflow. Hope that won't be as loud as the previous reference cooling.

 

Surprisingly the reference cooler is quiet, when we were benching the HD7970 we thought the fan died lol but under heavy load you start to hear it but not as loud while keeping the temps down. Your ambient will play a big role and they're not as loud as the previous gen references. Of course at max 5k+RPM it does sound like a tornado/jet but you probably dont need to set it that high , At AUTO settings it did get to around 70-80C before it started revving but again that was at overclocking runs 1.1GHz+ etc... Overall though in terms of the card itself, the 7970 runs cool so and in idle mode amd zero core kicks in so if you leave your pc on 24/7 on idle the gpu will use about 3w~.

 

Best Buy Canada has the Diamond version:

Well finally got my HIS 7970, gonna give a it a couple runs in 3dmark11.

Edit: ok so after getting MSIafterburner beta 11 apparently the default voltage for my card was 1049mv, so i maxed out the sliders 1125/1575 but it hung up in the first 3dmark11 scene, so i hit the voltage to 1106mv and got it stable.
Anyhow going out on a boozer will try to lower volts and see what i come up with stable at full OC.

 

sorry for my dumb question but how do we know our card's default voltage by using MSI AB beta 11? Is it by looking at the voltage monitoring or the default voltage slider?

Thanks.

 

Default voltage is given on the Core Voltage slider however the actual voltage will be less due to Vdroop.

If you want to find the VID of your card run MSI Afterburner from Command Line with the switch /rr174.

 

edit: solved

what do you think is the max safe voltage for a 7970 on air (daily use)?

 

Thanks Hallryu . So it seems that my card built with a GPU with default core voltage at 1.174v which is the highest one, no wonder it is stable even at 1160MHz core at default volt.

That's good to know.

 

There were some people being upset that their card couldnt do CCC slider max overclock but what they didnt know is not all cards had the same VID. We found out in one of our testing that the card was at 1.1125v, we bumped it up to the default 1.175v and the stock slider OC was easily achieved. Other people flashed their cards to the ASUS bios which already set the stock voltages, so for those people who are having trouble getting max slider OC try checking your voltages first.

 

I just received my 7970 card but when I ran the Heaven benchmark demo I got only 35.5 fps average(668) with 1080p and tesselation normal. I have a phenom x4 965 @3.4 ghz and 8 gigs of ddr2 memory. I do notice a big difference in BF 3 compared to my previous 5870 card. Is there something wrong here? I'm not sure what to make of it.

 

I ran heaven 2.5 again at stock clock just to compare with you and I got 48.8fps. my system specs as stated beside. btw I'm running at 1080p with 8xAA and 16x Anisotropy and tessellation set to normal.

I guess something's wrong with your score. Which driver version are you using currently? from AMD website or CD driver? What Windows OS you're using right now, Win7 64bit? If yes you can download latest AMD driver for 7970 from below link. Also please describe in detail of your heaven 2.5 settings, AA? AF? Could be your cpu that holds up your card or something else.

What he said ^^^ also, what ccc settings you have. Maybe you have enabled ssaa or edge detect aa or something along those lines which could be hindering performance. Perhaps your cpu holds you back but i wouldnt have thought by that steep of a margin. Come back to us with these details and we will go from there

 

Air, hot air 26* ambient 100% fan...

well so far 1175/1575 @ 1125mv, will go for a max OC tomorrow

 

And CFX

Do you have a link for those scores?

 

I got 66.7 in Heaven with the latest drivers (ones that came out yesterday) at 1080p, default settings, normal tess, just whacked all sliders to the left in the CCC (for performance).

 

Ok, I am using Windows 7 Ultimate 64 bit version. I am also using the latest AMD drivers from their site. In the CCC, I have Filter set to standard and the wait for vertical refresh option set to performance. The thing is when I set v-sync to off from the benchmark, my score goes up to 1458. Max fps is 135.8. With v-synch on the score goes down to 794 with max fps only 60. The problem is there is too much tearing with v-sync off. I have a Hanns-G 28 inch monitor with max res of 1900 by 1200.

Heaven settings are:
API: DirectX11
Stereo 3D: disabled
Shaders: High
Tesselation: normal
Anisotropy: 4
ANtialiasing: off
Full screen: checked
Resolution" 1900 by 1200

 

Yes this is because the fact that when we went from CRT to LCD, LCD stuck at 60Hz so any higher fps will cause tearing. This is where 120Hz monitors shine. Don't think of TV advertisements of 120/240/600Hz, they're pretty much interpolated. If you have a video card capable of dishing out more frames and you have a 120Hz monitor, you will "see" the difference. Its much smoother, you dont miss a thing and you won't have to worry much about tearing. Of course if you want to get most out of your card with a 60Hz monitor you can pump up the graphic settings, AA/AF will let your GPU work harder.
