This ^. I recommend 7970 users to use catalyst 11.12 RC11 that I put up the link in my 1st post. That's what recommended by AMD themselves. So for now, we just wait for AMD to release an official HD7970 driver .

kambing69, what's ur max gpu temp when playing games? and one weird thing, i overclock my cpu to 4.2ghz then i benchmark again with 1125/1600 my points drop to 9000

ECC at work

try lowering down the gpu memory clock

1125/1575 @ 1.75v ,Screen freezes, and then this comes out "ATI graphic card stop working and recovered..."



What should I do ?

No bluescreen.

Normally it run fine but just now it stop working and recover.

GPU Load Temp : 62degrees.

Benchmark also runs fine.

right now my voltage @ 1046 clocked at 1040/1450 this is the most stable i can get with stock voltage... i dont want to add voltage now because the heat, need to wait for my Water block from cyntrix >.< then il add 1.2 volt....for 24/7 hours...

owh my temp when playing game around 73' with customize fan speed (afterburner) . .
I find that the stock fan speed too slow and because my room doesn't have ac, i really need to customize the fan speed....make it around 50~80 at 60c and above...

sry for late reply, kinda bzy yesterday ..

Faith, you dont need to clock higher than 1040 for crysis2 or other for most of the game... because 7970 already fast enough even at stock clock~(unless you using more than one monitor) . .



im using 11.12 CCC already... just waiting for the officiall ccc for 7970.... arghhh cant wait, because skyrim +enb +SAOO max + FXAA max = crash >.< ahahaha

try download HWinfo64 v3.93-1530 (latest) and monitor max VRM temp during full load.
Link: HWinfo64

Although this is a 7970 OC thread. I hope this is quite a good info for guys who wants to know how 7970 vs 6990.

ASUS HD6990 - 11350 3DMark11 (OCed)
Core: 940MHz, Memory: 1320MHz

CPU: Intel i7-2600K @ 5.2GHz
Mainboard: ASUS Maximus IV Extreme-Z
Memory: Avexir 4GB 2000 CL9 x 2
PSU: Seasonic X-850

Have you guys download the new CCC ?

GPU-Z detect 2D clock >.<

I dint test the result yet...


EDIT: but it seem it OC'ed well, i mean my afterburner still working~

Added on February 16, 2012, 9:58 pmGood news!!! i hit 9k mark with the new driver update!!!

before this i get 89xx (oh well got about 150~250 more point ) dint know about other application (game) will try it out to see... hope no more crash for skyrim~

just got my 7970 today
minor oc to 20%,
1110 clock with no voltage rise
but temp shot to 93c lol....after 40mins furmark
waterblock plz !!!

nice bro...your default voltage is 1175mv? i believe at stock cvolt you can OC your card to at least 1150MHz . The Most Powerful single graphics card in the planet

Added on February 17, 2012, 12:10 amNice score on 6990 but its a dual GPU so its fair enough . Can you try benching your card at that clock with heaven 2.5 everything maxed out and extreme tessel? just to compare with 7970...

NICE!!!! . . . yeah the temp really let you down right? same as me... it shoot around 85~89 (playing crysis2 for 3 hours) @ 1150/1600 : 1175mvolt and my pc will automatically restart because of the temp when running OCCT for about 30 min >.<

yeap... all stock only slide the clock speed in overdrive....
will report back after tomorrow if my wb reach

HD radeon 7970 minimum power supply how many watt? 650W true power?

650 watt should be enough for average user. Unless if you plan to extremely OC'ed your CPU and GPU, then you might need a high quality 750W or higher PSU.

Just a recommendation , try TX series ( Corsair ) / Seasonic. U wont regret it. I hope you dont skimp on the PSU if you can afford the 7970. Just my 2 cents. Good luck.

Hi guys,

I have some problem over clocking my Club3D HD7970.
I went for 1073 / 1542 with 20% power boost and no voltage changes. I went to play BF3 and after few hours of game play PC shut down by itself.
I wanted to fire up my PC again but no reaction , black screen ,and power button's diode wont light up. Few minutes later the PC boots up by itself again.
So i went to test the card with Furmark. 15min burn-in test brought the card to 94c and just at 99% of the test bam! Again the same problem .. pc goes off and wont turn on for next 4-5 minutes and then boots up again.
Can anyone tell me why is this happening? Is this some thermal protection kicking in on the 7970 and turns whole system off to prevent damage? Or does the card need more voltage to get this stable? Or is my PSU failing? The last option is really unlikely because i have no problems otherwise on stock settings. I really hope somebody can clear it up for me. Thanks!

sounds like you are overloading the card in terms of heat. Not to sure about the brand. I remember when i used stock cooler and set the settings to something like yours did not shut down after playing games but temp was around 85C. Not much use to increase the voltage because it would get heated up faster.

what psu are you using.
I think this card you really need to invest in either the AC triple fan 7970 cooler or get it watercooled.
I remember my stock temp was around 72-75C playing 3rd person games. This is with a high flow chassis.
with water cooling overclocking to 1200/6600, temp is around 38C after games

I'm using Zalman 850watt PSU and got Antec 180p case with 3 intake and 2 outtake fans.
I have ordered : ARCTIC Accelero Xtreme 7970 VGA but have to wait for it to ship about 3 weeks :S http://hexus.net/tech/reviews/cooling/3480...970-vga-cooler/

Increase voltage & fan speed would it help?

Mean time run the fan like jet engine only. THat helps. 50% is already way to loud for me.
But its better to set to 50% straight away so that the temp takes a longer time to reach 80C.

Want to ask does overclocking help much with BF3? i don;t play much FPS so don't notice much difference when i overclock.
