wow! bro..can put up ur 7970 pics?

Are you serious?

Overclock it to play what game? If I were you I will not reduce the life of my expensive GPU for a few fps

Actually 7970 is only a tad faster than the GTX 580 If you're talking about high resolutions like 2560 x 1600 on certain games, you still need a Crossfire setup to get a good 60 fps. Overclock does reduce life span but it will be years before it does. I don't think anyone would mind if their 7970 dies 10 years later.

bro, when you play latest games with all eye candy sets to the maxed possible, you'll know that even the most powerful single GPU also struggling to maintain a playable fps especially when you play at 1080p or higher res. That's where GPU OC taking its part to produce more fps = smooth gameplay. You're right about the life span, but to me as long as we monitor the temps and control it wisely everything should be fine, believe me.. I may not an expert when it comes to overclocking CPU/GPU but from what I read and learnt from OC old timers all over the net, and with some experience in overclocking GTX8800s, HD5850s, 6970s before..i believe as long as we know what we did, the GC should be fine.

Most importantly, we didn't use highest achieved OC for 24/7 but instead just for benching purpose and try to get a highest score possible. same goes with those who OC'ed their CPU using subzero/LN2 etc...they didn't do that for 24/7 usage but just for the score and to exceed the limit+ for fun...just my 10cents though .

Added on January 10, 2012, 7:43 pmsorry bro, i dont have a decent camera so i didn't capture any photo. maybe tonight I'll capture some and upload it. This is a MUST HAVE card for all 'extreme pc gamers' .
1. fan really silent
2. the design is superb
3. this card is really cold
4. easy to OC, can OC up to 300MHz+ on core and up to 250MHz on memory easily, just need a small bump on voltage.
5. very stable OC

thumbs up for the "very stable OC"

I see. Thanks for clarifying bro

1285/1615: 9938
http://3dmark.com/3dm11/2518309

will try to up some more since I am now at 1.25v with 1285clock...maybe can get past 1300MHz with 1.3v, hopefully can get a 10k+ score . Btw, the temps never exceed 75degC with 70% fan speed.

amazing!
very nice clocks especially on air cooling.
go go 7970!

As usual the reference hsf is quite noisy. Can't wait for the blocks.

Just warranty your graphic card if anything went wrong
That's what it is for

Unigine heaven 2.5 all settings maxed out @ 1920x1080.



not quite impressive as i imagine since min fps still below 30fps.

wow on ref cooler 1300 mhz!!!! thats insane bench some games dude like bf3 crysis 2 arkham city lost planet 2 metro 2033 avp using all maxed out settings please

also whats your noise/temp??

after overclock you will face overheat?

really looking forward to my queries some guys here got it to 11500 with 1230 on the core that beats asus mars II dual 580s

http://www.xtremesystems.org/forums/showth...rd-Post-It-Here!

I'll do some game benches and update here later on. at 65% fan speed, this card is quite noisy but still acceptable if compared to HD6970...temps are up to 75degC but in a/c'ed (24degC) room.

yes, definitely but as long as you manage it with fan speed etc everything should be under control .

no wonder he got 11700 only at 1230..he's using a top end cpu/mobo/ram with very high physics score and this will affect graphics score as well. Nice score & nice system over there.

just compare the graphic score and ignore the physics

few hundred more mhz in cpu only contribute single digit improvement in final score

forgive me but that's not quite true if base on my OC'ed results. Even if I upped my cpu clock to 100MHz, the final result in 3dmark11 increased for about 120points. So to me, cpu play its own important part in contributing a best final score for 3dmark11 and vantage. But really its just a number..if let say we run it 5x at 4.0GHz and 5x at 4.3GHz then we may have different POV on the final score .

interesting

would really like to compare the gaming physics performance with nvidia physx...

Not even close. AMD card's physics definitely cannot compared to NVIDIA physX no matter how powerful its raw power performance. I hope this is what you mean..

i would really hard to imaging playing batman arkham city using AMD Radeon without physx...eventhough the FPS rock steady...

What to do.. physx-like Havok feature is not implemented on AMD card yet
but i don't know whether u could use a hacked driver to enable physx on this 7000 series with the latest driver + games.

already buy hd 7970 ????......................nice.......

This post has been edited by primaroti: Jan 13 2012, 10:23 AM

imagine what this beast can do when the driver is mature!!

Yes master Kevin, i need to do some googling to find out whether this card already supported with physX card to play latest games like batman arkham city etc..but i guess it'll take some time for the work around .

haha ya lorr, cannot resist anymore as I found those reviews on this card was sooooo charming hahaha ..if got more money sure will grab another one, then I'll sit tight for maybe 1-2years enjoying new games

hopefully by time, AMD driver support team are working hard to satisfy their 7970's customer after what they've paid. I believe there's much more potential in this card, only time will tell . thanks for drop by..


This post has been edited by shepard: Jan 13 2012, 01:01 PM

Our brother Kevin already got 2 cards on the way to him

That's good to hear, I will no longer doing OC'ing and Benching alone here then .

I take leave today just to play around with this card haha , got some scores to be shared and to compare 3xhd5850s performance with single hd7970 in some games/benchmarks.
Now for a start Unigine Heaven 2.5 with everything maxed out...hd7970@ 1225/1625 stable for 24/7 usage on air




ok now i7 920@4.3GHz with 3xhd5850s @ 950/1200 scores with unigine heaven 2.0 all settings maxed out:


i7 2600k@4.5GHz with HD7970 @ 1225/1625 - scored even higher than 3x5850s OC'ed above..great tessellation power INDEED!!


Since I've kept some benchmark scores of my old 3x5850s system, I can at least compare those results with 7970 scores in a chart later and share with you guys here... hope to see a good score.

______________________________________________________________________________________________________________________________________________

3DMark Vantage comparison ( 3x5850s vs 7970)
3x5850s OC'ed @ 1025/1200 + i7 920@4.4GHz




hd7970 OC'ed @ 1300/1650 + i7 2600k@4.5GHz



HD7970 is a true winner against mighty 3x5850s


This post has been edited by shepard: Jan 13 2012, 02:18 PM

wanna see u 3x7970s so badly!! haha

monster gc........................hhahahahhahaha

To be honest, there's a limit what the drivers can do. What's important here is the support of drivers for that particular game. It doesn't mean that 6 months down the road with Catalyst version 25 coming out, we will get extra 10-20 FPS with it

haha..true bro alvin, what i mean is their support, and also possible if the new driver will make this card even more stable in OC that'll be great as well. Actually the improve in FPS is subjective and only applied to some games/ apps upon new driver release..we dont get an overall 10fps for all games..new driver means better games optimization but not for all games. Right now I'm playing Skyrim with hd7970 and microstutter is there all the times, this won't happen with nvidia cards though..this is where we need AMD support to improve on their driver in games etc, in terms of FPS...this card serve me more than I need already..no complaints at all .

Update: After ran through a couple of benchmarks and games tests...I dare to declare that HD7970 is even more powerful than 3x5850s in terms of overall raw power(fps) and of course tessellation power. However, I just compared my HD7970 with my old Trifire setup that use an old driver. But as bro Alvin mentioned, new driver wont produce an extra 10-20fps so there's no doubt already. I believe this card also able to beat 2xHD5870 when it comes to OC'ed vs OC'ed. IF at stock, maybe those Trifire and CFx is better. Thanks to HD7970's huge OC headrooms .

Wahhh...got new toys lagi ahh...

I wanted to get this but after seeing this chart its like a step backwards in terms of relative performance...haihh...1 year more to live with it...



I have 5970 yeah...so not worth the hassle of upgrade...for now

This post has been edited by antonio: Jan 17 2012, 10:45 AM

It's not a step backwards. The 7970 is literally the best GPU AMD every created. There's only "one" gpu in the 7970 as opposed to the 6990 which is 2 x 6970 (crippled), and the 590 (2 x 580). An OCed 7970 is very close to a 6990. The benefit of 7970 is that you can run 4 pieces of them which is equivalent to almost 8 pieces of 6970's performance. On the 6 series card, the best you can to is 2 pieces of 6990 and that is only equivalent to 4 pieces of 6970.

I know what u meant, but as it turns out, I don't do benches nor do I play games just because of the need for higher frame rates to appear...All the games that I 'play' runs smoothly and ditch my current card and fork out money on 1 or maybe 2 pieces of the 7970 card which might only better 10-30 fps doesn't really floats my boat...

Sure if I currently am on a mid range 2 generation back GPU I might think of getting 7000-series GPU but it turns out, I'm getting more than enough frames on my games, I'll probably skip the 7970 and either fork out for the 7990 or some other card after the 7-series...

7970 is probably the best single GPU out there nonetheless...

Great, hope we can see your OC results for both cards. dont forget to update us on 7970s CF & TF performance as I am looking forward to add 1 or 2 more of this beast and then watercooled them...haha I'm so excited!

btw bro Kevin, do we have any reviews on those 7970s WB in the net? so far couldn't find them.

afaik no review yet & i think i'd grab the EK plexi-Ni blocks coz i like see-through.
i will switch to 7970 right after CNY. now i'm very2 busy with CNY preparation etc lol.

Alright,

here's some update on the 7970's OC potential and performance gain OVER STOCK that we could get in some of the latest/old games once we OC'ed this card.
Resolution:1920x1080
AA: 4x MSAA
Anisotropic: 16x
Graphics Details: All Maxed out except for unigine 2.5 with Normal tessellation.



FPS gain plotted in pareto:


Another chart for Vantage and 3DMark11 results:


Performance gain(%) pareto:


So I would say that we can easily achieve 20% more performance out of this card ONLY IF we are lucky enough to get a good 7970 chip. I'd say this because I read a lot of complaints from 7970's users in the net on how their card cannot OC'ed beyond 1100/1150 and heck, some cannot even past 1070MHz neither at stock nor higher voltage. It's like a lucky draw I guess, and maybe this is the reason why AMD set their 7970's stock core clock as low as 925MHz even though most chips can go beyond 1250MHz stable on air.

By watercooled this beast, i think we can even get a 30+% performance gain out of this beast, amazing!!

This post has been edited by shepard: Jan 19 2012, 08:44 PM

Give some good cooling to it sure can oc more n stable!

Nice reviews again Btw, what are the temps like at 1275/1675 during gaming?

Thanks bro Alvin, I love to spend time play around with GC . max temps when I play crysis 2 and metro 2033 at 1275/1675 is 71degC but I am in A/C'ed room(22degC). I set the fan profile to inrease the speed in linear from 40deg=25% to 70Deg=60% but 7970 stock fan was less audible compared to my previous 6970. furthermore I always play games with loud speaker or headphone so the fan's sound is not a concern here .

Anyway bro Alvin, got any plan going Red again? or waiting for GTX680/780?


Definitely! no doubt about that

The fan really anoying at 65%++ >.<

I want water block!!!

Bro, hope you can share your 7970s Trifire experiences with us soon. If it scales well, I might need to consider for Trifire as well. Last time when using Trifire 5850s it scales very2 nice with performance gain about 2.6x-2.9x over a single 5850. If this card does scale around 2.5x above in games/benches then without hesitation it is a MUST BUILD setup

Welcome my friend 7970's owner . if you going to water cool this card first, kindly share your OC experience later ya? I might need to wait until march to build a fully WC setup due to budget constraint now haha...

btw, there's no need to set the fan up to 65% speed lol...are you doing benching with those fan setting? but yeah, at 60% above the fan start to annoys me.

Sure... but i dont know why my 3Dmark score is 0 >.<

Its been about 5 years since im benching my rig ahahahah

help here~

here the pic...


and why my score really low ? or is it because i max all the setting.....

Yeah will do some benching. Maybe 10% OC on each card to see how well they fair. If someone wanna donate a 3930k + RIVE to me, I can do 4 cards.

Oh btw, BF3 ultra everything on the cards with 60fps (vsync on). I'd like to disable a pcie slot to see if 2 cards can do the same. Do you know if I need to remove the CFX cable after disabling the pcie slot?

This post has been edited by CyntrixTech: Jan 21 2012, 10:05 PM

I am more interested with VSync off tho since it does force the game to run in a constant framerate and can be misleading

Yes, you cannot manually set the settings or you'll get 0 3DMark score. Just go to option tab and select one preset setting either "Entry, Performance, High, or Extreme" but normally people will use "performance" preset to compare the scores. Try do this first and see how much you can get. Thanks for sharing .

Whoa!!..cant wait to see how those Trifire beasts perform in games/benches. It's even good to know how far it can go when you start to OC all of them. I dont prefer quad CFx tbh because to me it's too hassle and from what I read on QuadCfx of HD58xx last time it scales very bad but not sure how it perform on newer generation of AMD cards though. But yeah, I do need those killer combination of RIVE + 3930k/3960x LOL . You think better grab these or wait for ivy bridge later in Apr, any idea?

I wonder why you enable vsync when you're using 3 powerful cards for gaming/benching? . We wanted to see how powerful your Trifire setup performed so i guess it's good if you just turn off vsync on any games/benches or we might end up with constant 60fps all the time from your setup .. I'm saying this because my single 7970 can almost do a constant 60fps on ultra settings in BF3 as well maybe in heavy firefight it will drop to <60fps like when there's and explosions etc. I'm gaming at 1920x1080 btw, are you gaming with eyefinity setup? res?

I am not so sure about removing CFx bridge but from my experience with my Trifire 5850s. You just need to disable one of the card if you plan to run only 1 or 2 cards and no need to remove the CFx bridge. That's what I did last time when benching single and dual cards and it works that way. give it a try first and see, i dont really think you need to remove the bridge though.

This post has been edited by shepard: Jan 22 2012, 02:49 AM

vsync is important to prevent screen tearing. My screen is the u3011. I disabled vsync earlier and in huge open areas with lots of effects it was lowest at 58 fps but 95% of the time it is 60-130 fps. Indoors i get about 160+ fps. But i think there is some cpu bottleneck with my 2500k running at stock speed.

Nah don't bother with 3930k, it doesnt perform any better than 2x00k for what matters to most people. It is not easy to get every 3930k core to 5ghz so it performs worse in gaming than a highly clocked 2500k priced 3 times less. Just like e8400 vs q6600 back then. I am waiting for IB or x79 quadcore K series.

Yeah I know vsync purpose, what i meant is that it is not needed if you want to benchmark your setup to see how powerful it is. Vsync is important if you're gaming though. So are you going to benchmark your trifire say for crysis2, metro2033, far cry 2, warhead, 3dmark11, 3dmark vantage etc?

cant wait to see those scores..thanks for your update

nice score right there m8! later will try to benchmark at EXTREME preset for both Vantage and 3DMark11.

Tried MSI Afterburner beta 11. Set the card core voltage to 1.3v with 1325,1320,1315,1310,1305MHz but all crash during benchmark. looks like this card really need a water block only then it can surpass 1.3GHz clock speed I guess.

Now looking for WB for this card and will update here my 7970 OC experience under water soon

Very good one Kevin! Nice apple to apple comparison with a nice score on both setup especially CFx 7970s . Now I cannot wait any longer for another 7970 . Those scores and Dirt 3 FPS is truly an Overkill, furthermore benched at 2560x1600!! Woww..Impressive!

Thanks for sharing.

NICE score..!!!

I cant even make it for 1150/1575 for stable OC now... it seems it really need water block >.< ... because i ran graphic test for straight 3 hours and it seems there 2 error detected (with temp avrg:78 max 82)

PS: and when i increase the cvolt it crash ....

This post has been edited by kambing69: Jan 31 2012, 07:14 PM

Which brand of 7970 you r using right now, Gigabyte or Sapphire? could you please share with us which benchmark you're running above, is it 3dm11, Vantage or Furmark?

I wonder how come some 7970's cards cannot even past 1150MHz even after bumping the coreV..this is not a good news since I'm going to grab another 7970 soon...hopefully my 2nd card will be as good as my 1st card.

This post has been edited by shepard: Jan 31 2012, 09:13 PM

Mine was gigabyte version . . . it can be OC'ed at 1150 but the heat was #$%^&, unless i manual set the fan... i tried bum volt . . . but ntg happen, its kinda weird because i still can only max OC it up till 1150/1575 or do i need to restart PC to adjust it further?


BTW i share my OC result in this thread before

what software do you used to overclock the HD7970?
looking to do some overclocking

no program is needed. Just the AMD Overdrive will do. MSI Afterburner may be compatible.

Driver and Software:

Latest driver:

Beta Drivers (8.921.2 RC11)

Software:

Atiman Uninstaller v.6.2.0 (used to clean out older Catalyst drivers)
ASUS GPU Tweak 2.0.3.0 (requires the ASUS BIOS to enable voltage tweaking and higher clocks)
MSI Afterburner 2.2 Beta 11 (latest beta version)
OCCT 3.1 (newer versions don't quite stress the card as much)
OCCT 4.1

BIOS Files:

Automated Xtreme OC BIOS flashing tool: Tahiti_XT_C3860100_X00_BIOS_Dec20_2011.zip (420k. zip file)
Please note this BIOS is only for the reference design (PCB) HD7970.

OCCT is for GPU or CPU??

Both GPU & CPU


link updated!

For the OCCT how much shader and what resolution should i use.. the default?

the higher the more stressful.

So Bro Kevin, are you going to share your CF/TF OC experience and benchmark results on those cards?

Just ran Lost Planet 2 DX11 benchmark this morning with HD7970 @ 1275/1685MHz:
Test B
1920x1080

just got the wb's & single slot I/O plates & another 7970 for TF so in this weekend I'm going to torture the cards under water.

Nice marks...but i dont play lost planet, dint like FPS actually... playing skyrim now >.<

Quick question, CCC version 12.1 dint support 7900 series right? so we using 11.12?

12.1 is fine for 7970 but 12.2 doesn't work right.
SOS

Great! let's see what it can do under water

Haha me too..I didn't play Lost planet tbh just ran the benchmark. Same like you enjoying skyrim, Batman AC and BF3 currently .

I stick with 11.12 RC11 since it performs well compared to 11.12_7970 and 12.1 WHQL...Other forumer compared the results between these drivers and help us to choose which driver performing better.. but I might lack some of the CCC new features.

It is a Gigabyte Windforce HD7970, flashed to asok bios for the memory voltage adjustment..

Nice score on a single card bro! Mine cannot even past 11k even with 2600k clocked at 4.8GHz. Your 3930k SB-E at 4.5GHz got more juice than my SB @4.8GHz...but i doubt the FPS in games will be much differ compared to your system am I correct?



Edit: Wow!! I just saw your mem clock...it's 2000MHZ ?? are you running your card on air or under water?

Another 3D Benchmark at 1920x1080, cpu at 4.6GHz / HD7970 clocked to 1300/1685 at 1.3v. Average 195.05 FPS.

lol , my asus hd7970 only can be overclocked to 1075/1525 =(.. higher than that my screen will freeze

That will be something really disappointing as most of the reviews on 7970 can easily achieved 1125/1575 at stock volt. It appears purchasing this card and hoping to get a decent OC headroom is like a gamble thing, some outside forumers also stuck at your speed. Btw, which PSU brand u r using right now and wattage?

My PSU brand is Silverstone strider gold 750w. I tried to increase the gpu voltage but still fail to increase the overclock

750W gold is plenty enough.hmmm...

I wonder what application you're using to OC your 7970? if MSI AB, then which version (beta 11 or 12?). Did you set your GPU chip default voltage in MSI AB?

Maybe you can share your system with us? I hope we can somehow get your card to achieve at least max OC in CCC overdrive..

I used 3 application , 3 also can't.. CCC,ASUS GPU tweak,Sapphire TRIXX..

i7-2700k 3.5ghz
ASUS HD7970 3GB
1TB HDD
120 GB SSD
750W gold
ASUS P8Z68-V/GENE3
8GB Ram

Haven't try to OC with MSI afterburner..

Need to hard reset my comp when i max the overclock..

Btw, if keep failing will the GC spoil ?

Please download MSI Afterburner beta 12 first, install it and from there I will try to help you to set the default voltage of your chip using MSI AB. Do you know your GPU chip default voltage? I'm asking this because 7970 chip's default voltage are varies due to low leakage and high leakage chips used.

I'm not sure how this will help you in any way but can you check the ASIC score of your card using GPU-Z 0.5.8? just right click at the top bar of GPU-z and select ASIC score...let's see how your 7970 scored. Btw, have you OC'ed your CPU?
