Im having issues trying to Flash my HIS to as Asus to see if it will help.

How did you flash yours?

Also FFFUUUUUU !!!!

Use latest version , supporting Tahiti
atiflash_395.zip
Boot dos, place you bin/rom file in atiflash folder and use -f command
that's all.

Nice overclock with your 7970!

Mine simply wasn't staying stable without giving it a ton of volts.

I'm fine just leaving it at 1125/1600 at default w/ overdrive just for the stability.

Ahhh I was trying the Winflash method.

When I get back home next week Ill have another go, cheers.

Hi guyz,got my new Asus Directcu 7970 1gig edition yesterday...what a mamoth...its hugh.

This was the first part of my system upgrade to arrive so of coarse i had to play with it but installation was`nt without hurdles,
i knew fitting this card in my TT mozart tx case was going to be tight but oh boy,yes i cound of got a bigger but i chose the mozzart because it can accomodate 2 boards it has plenty of room for my planned dual loop water cooling setup,
i finaly get the card fitted with 4mm gap between my card and my front fans.

Having looked at various 7970s and found most of them to be powered with 6+8 pin i thought im fine there having 2x6+8 and 1 6+6 pin power cables...ahh...next problem,this card has 8+8 pin so ive used 8pin from one set and 8 from the second set of pci-e power cables...problem solved until i want to add a second 7970.

last problem which gives me cause for concern,after i installed my card i installed the asus tweak software to see if it had anything that msi ab doesnt,on monday everything was ran cool and quiet with settings on stock and fans on auto control while bench marking and some gaming but tuesday i found an issue,after playing on Avp 2010 for 30mins or so i alt/tabbed to check something on the internet and my gpu fans started to spin up for a second and return to the default 10% fan usage so i checked the temps of my card and asus tweak was reading 93c,i closed asus tweak then restarted it and temps returned to normal,so now im wondering if i have a dodgy bios,software or gpu that needs rma`ing

has anyone else had this issue while running asus tweak

thx in advance

The user defined fan profile button and general setup are not brilliant I hope they tweak them in later releases. However, using the Asus utility I haven't had the same issue as you had. Try setting a fan profile and see if that resolves the issue.

[The Goose]

just d/l latest gpu tweak it seems to be more stable than the 2077 version that came with the card,im also wondering if asus run a burnin test before the cards are packed away ,that might explain the peak in temps,has done it since i wrote the original post

[Comrade_Jerkov]

Got my 7970 up to 1200/1800 @1.23 and ran it through 3 loops of Heaven benching it once. No artifacts or anything. Temps maxed 70c w/ dual-x fan running at 65%.

I got 83.6 an with my i7 940 running at 3.63ghz. I recently bumped it to 3.81 with the vcore at 1.28. So I'll probably run a few loops of heaven again to see if that 83.6 bumps up to 84, but mostly to see what temps will be under a gaming load.

[Comrade_Jerkov]

Despite benching on Heaven stable at 1200/1800 w/1.23v, the driver still occasionally crashed as well as sometimes games would not start. So I bumped the voltage up to 1.243 and so far so good. I really don't want to bump it up higher but I really don't want to sacrifice the 4xMSAA in BF3 which the card can't really do smoothly under 1200 core...

EDIT: My monitor just randomly didn't wake up from power saving mode...Not sure if that is from the overclock. Computer was running and the hdd responding just the monitor didn't want to wake up. Might just be my monitor, I bought it in 2009 and it's sure to have taken a few bumps from moving from Germany to New Mexico and then to Massachusetts on top of the heavy use. My good ol' Acer!

[Colt M4]

try dropping your memory drop some that might help you run lower voltage. I have the same core speed a 1.225 stable if that helps.

[hallryu]

Just been running Heaven at 1200/1750 looped for about half an hour. No artifacts its just the fan noise on my reference card! lol

[Comrade_Jerkov]

My monitor just went into power saving mode again while I was in use and wouldn't wake up! Happened while the card was actually at its default settings, so the overclock doesn't matter. I'm starting to wonder if the 1 month old 7970 is bricking.

I finally settled on 1225/1650/1.187v and leaving it there.

Max temp in Heaven Settings on high 74c.
Low fan noise even maxed.

^Wow nice OC really low voltage for those clocks.

[Colt M4]

Well got something weird my 1200/1575 at 1.225 overclocked worked perfect in all my games including bf3 now a week after using it bf3 is starting to artifact with black triangles, backed it off to 1125 and its perfectly fine.

Your settings could have been on the edge.

Could even be Ambient temp change and higher heat.

Its also the chip lotto and not all going to clock the same.
Just like CPU's.

[BLEH!]

Are the newer cards a bit better at getting higher clocks on lower voltages?

[Colt M4]

Irocing up the voltages maybe? was at 1.225

Good play on words.

1.187 here with my 1225/1650 and leaving it there.

Games go to 69c under load and Heaven and 3D Mark hit 74c.

[Colt M4]

you it 74c thats high for those volts and you have the same card as me. is it cause of the arizona heat?

Thats correct,

Don't like AC and Ambient here is 85F.

Had to downclock my CPU to 4.2-4.3 to keep it cool.
Even though running 600.5 worth of water.
Its a summer thing or close to here.

But have to realize the BenchMark tools are going to load the cards heavier than the games so take that with a grain of salt.

But even at 74c BenchMarking, No Artifacting or problems.

Best card as to improvements have ever had and that goes back to the VooDoo and Radeon 9500 days.

1200/1800 is still running nice and stable @ 1.243 in games. I've started only using the overclock when I play games though and when I'm doing other stuff I just set Trixx back to the default clocks and voltages. No need to overclock when browsing the web as GPU-Z still shows use while using the internet even with hardware acceleration off.

Does anybody else do that?

Might check and see if 1800 on the Memory is even helping you at all.

Why run it that high if you don't have to.
And if doesn't, Might run a little cooler and be able drop the voltage to do it.
Core clock is where its at, Not so much memory.

Might help with Eye-Infinity if thats your thing.

I've always figured that s higher mem clock helps with heavy AA and AF/post processing and textures. Granted, probably more so with higher resolutions and eyefinity setups like you said.

It seemed to help out with my heavily modded skyrim w/ super sampling but at 1080 the difference isn't huge.

I had some free time tonight, so I lowered the mem clock to 1650 and voltage to 1225 as well as bumped the core to 1225.

I played skyrim for a few hours and diablo 3 for an hour after that. Ran stable using the automatic fan setting never passing 60%. Temps under 70c. Honestly not seeing a difference in fps as the increased core might have compensated a little.

I benchmarked Heaven @1920x1080, 4xAA, 16AF, normal tessellation, and everything else max and my score actually improved by .2 (83.8)
