replace my 7990

I'm not saying you shouldn't upgrade, but have you tried making a CCC profile for shadow of mordor and using the Lost Planet 2 DX11 xfire preset?
Also, ultra textures really don't make much or any real difference IMO.

yeah i have tried most profiles, strange thing is on the mordor game benchmark it comes out stupidly high, but ingame it stutters and the menus are messed up.
so i am running with 1 core. and to top it off its just lost my 15hr saved game..
 
FYI my 7990 works in shadow of mordor both cores crossfire, the only issue you get is in the options menu the text messes up when you hover over it, until a patch fixes this, but it's perfectly playable still in game.

I mean game benchmarks - ones most people will be realising card performance for and what the OP is using a card for

I was more thinking something like this where the 7990 has been used in modern game banchmarks for comparison. The Anandtech is using historical data for older cards. Games and drivers have advanced older card performances.

And graphical benchmarks - well buying hardware to get a bigger number dont sound like fun to me. But each to their own.

Any recent game benchmark would show the 690 (probably to a lesser extent 7990) in a worse light with its 2gb vram :P, watchdogs was unplayable on it.

7990 vs 970

Bare in mind both are stock and the 970 can overclock rather well. Certainly not a walk over, especially when your comparing a single GPU vs a dual one.

no this is wrong because 80% of all 7990s have to be undervolted and underclocked to keep their temperatures down (on air).

the 970 is therefore faster, because my card is deffo quicker than my 7990.

Have you tried using the 7990 custom bios that is somewhere around on these forums thats meant to stop the throttling.

I can't understand why you keep screaming HOT HOT HOT on every AMD thread especially the 7990. We told you how to cool yours in a very poor case most of which you ignored.

Everyone knew the 7990 ran hot BEFORE they bought one and it doesn't run THAT hot. WE ALL KNOW AMD cards run hotter. Now give it a rest man!

Folk undervolted just to get some temps down. In the grand scheme of things the 7990 is a few degrees hotter than other cards as per the delata T's in the review below. STick it in a hot room coz you wanna sit in yer skiddies and a poor ventilated case - voila!

HOT temps!

the 7990 isn't just hot is it ! plus it wasn't in a poorly ventilated case.....very well ventilated.

the 7970 was hot, but the 7990 is more like a Volcano, enough said :D

Not everyone had the same experience as you, Mal.
I reckon you just had a ****ter of a card.

Inb4 review samples etc...

I'd agree with him, I had the same issues and after looking around online a ton of people had the same issues. Reviews had a cool quiet running card (generally 65-70c load and whisper quiet) while a lot of retail boards seemed to run well into the 90's with the triple fans spooling up to mad levels trying to keep temps under control. if you look around online you can find loads of people with exactly the same issues. For me comparing my card to what they stated it SHOULD do in reviews was literally a night and day difference.

Just seems to be bit more than coincidental that reviewers virtually all had cards that ran how amd advertised. Loads of people on here also had cards that routinely ran well into the 90's and they had to mess around with voltages and bios files to get them running at near acceptable temp and noise levels. Personally id prefer to have it run as advertised out of the box instead of having to mess with it to try and get it even vaguely close to what the reviewers' experienced.

I agree with you mate.I have 2x7970 under water now.One is reference model and second one is msi tf3.When they were working on air temps where crazy during summer time 87-90 degrees.
So I can imagine how it's to run 7990 on air with reference cooler.

87-90............. More like 92-94 :eek:

but underclocked they were 84 degrees, but of course with a massive loss of power..you loose about 30fps

the 7990 is a really good bargain on Ebay, but it deffo needs water.........or an open air test bench design
 
Run mine at stock volts with non throttle BIOS so it's at 1000Mhz solid. Never goes above 85 degrees and that's in the summer. Noise? Well I wear headphones when gaming and they are known to be relatively quiet.

The problem with the 7990 is that only some of the air is exhauusted from the back of the card. The rest is from the sides into the case. You need excellent supply to the card and an exhaust. I modded trhe window on my case with a fan feeding air to the top of the card and I have one rear exhaust and the two H100i fans will not only cool the rad but as the hot air rises in the case it draws this out aswell. There is also another intake fan pumping air at the front of the card. Silverstone TEMjin TJ10 case.

There are two types of reference 7990, some 7990's only boost to 950Mhz and some go to 1000Mhz. I wonder if there is a link with one or the other running hotter? Maybe those GPU's binned for the lower spec ran too hot to get to 1000Mhz so they ran them at a lower clock speed but they still run comparatively hot.

Undervolting should not lose you performance unless you have undervoted too far. ypou only undervolt to the point where you lose no performance. 30fps? At what res and which game? 30fps is massive and shouldnt be a result of undervolting.
 
i've just seen something

quadfire 7990s for sale.... both are watercooled, what do you think guys?

compared to the 970 that is
