Shouls i RMA my 5 hours old card? 7970

Did you use drivers shipped with the 7970 or ones you downloaded from amd.com ?

Also, what make/model of power supply are you using?

I used them from the AMD site, and it's a "combatpower 750W" Dunno what it is?

Edit: It's a Inter-Tech Combat Power CP 750W

Could it be a power problem? Cuz i didn't have any power problems with my old 5870...^^

Yes, it could be a power issue (or a heat issue as well).

First, I have ZERO confidence in the quality of your power supply. Although rated at 750 watts, I would think that claim is questionable.

I would replace that power supply with a quality one from Seasonic or Corsair.

What are your CPU and GPU temperatures when gaming? Also, are you overclocking anything (CPU, GPU, memory)?

What are the specs for the rest of your system?

No i don't overclock only my cpu wich has been overclocked since i got this pc 2 years back.
And that's OC'ed from 2700MHZ to 3400MHZ

The GPU is Overclocked standard so i don't know if thta counts  


8gb of Corsair Vengence ram 1600MHZ
Processor AMD Phenom(tm) II X4 965 Processor, 3400 Mhz,
Motherboard Gigabyte GA-870A-UD3
1 2tb HDD Western Digital (dunno which one
2 150gb HDD Seagate Barracuda 7200 rpm

It's around 60-70Ceclius when it's on load


Edit: I will try to put in my old RAM and see if that helps  
Edit Edit: I've now been playing for around 1 hour with my old ram and i de-clocked the card so it runs at the normal rate (This was the OC version) And i use 10% less power on it and it seems to work so far  

I really think that your PSU is at the core of the issue.

So do i but i got it fixed with a little quick fix  

What this guy said. Power delivery is probably inadequate. That crummy 750 watt PSU probably has about 400 watts on the 12 volt rail and can stably deliver 250 of them. Get a good 750 watt SeaSonic or Corsair (manufactured by SeaSonic) instead.

By downclocking the GPU, right? That indicates that your PSU is inadequate.

Just keep that in mind. Be a shame to damage a great GPU with a flaky PSU.

Good luck!

It could be also the overclock from factory that causes that, there's several cards that happen like that.

No need for 750W, 550W would be enough. And XFX and Antec are just as good as Seasonic and Corsair (all XFX PSUs are made by Seasonic AFAIK, not all Corsairs are).

Ya, don't buy a rosewill PSU. They are junk. Fired a couple of buddies system.

Rosewill is not junk, the capstone, hive,fortess and green are good psus.

I wouldn't buy one!!!

Rosewill Fortress* and the others i mention are good ones, see the reviews on hardware secrets, anadtech, Jonnyguru, etc.
But for the op, since it's a european psu that he got(in the description), the best will be a xfx or corsair.

I guess you also wouldn't buy from other companies that use the same OEMs that Rosewill does....logic :\

I don't care if a companies uses Rosewill, I build my own PC!!!

Just get this PSU:

Only $64.99 and will run your computer nicely,

Or this Corsair 600w PSU for $69.99

Your problems will soon be solved  


"I had a similar problem after upgrading and my 450w was just slightly underpowered and couldn't carry the load"

Mind you running with to less of power, is a great risk to your other components, Its not wise to do this. You can always take off fans if your not overheating, or reduce the overclocking of your items, but the best solution is to upgrade the PSU to one that can handle your load  

Try comprehending when you read please. In case you didn't know, Most companies that sell PSUs DON'T make them themselves, they buy them from an OEM such as Seasonic. That's what I meant, since you say you wouldn't buy any of Rosewill's quality PSUs, I assume you will also maintain integrity by avoiding other company's quality PSUs that are made by the same OEMs.

Rosewill as known to explode and fry computers, Last I knew they have only had 1 successful model, the rest are cheap pieces of junk, Where do you get quality at ?

Just 2 little posts all about rosewill psu's and how bad they are  


But to point this out:

Rosewill PSU's OEM is SuperFlower
SuperFlow PSU's are made by FSP...

I speak from experience that's all. Buy what you want. No skin off me!!!

Not necessarily.

550 watts is pushing it for a 7970. If we assume that a good 550 watt PSU has at least 450 watts on the 12 volt rail we can break it down as follows:

250 watts for an overclocked 7970 (XFX Black Edition according to the OP)

75-150 watts for a stock CPU, but 100-200 watts for an overclocked CPU (inclusive)

Up to 10 watts for the PCH

Up to 20 watts for the memory

10 watts per platter hard drive

1 watt per SSD

4 watts per case fan (120mm)

Even a modest gaming PC will blow past 450 watts DC when equipped with a factory overclocked GPU and modest gaming CPU. My PC alone draws over 700 watts under Furmark conditions and up to 900 when mining bitcoins.

Well now i got myself i new problem... I got it working, for some hours but now wheni boot on my pc it works for 5 mins, turns the fans up and freezes the computer 1 min later screen go black adn then nothing happens, but when i open up the computer in Safemode nothing happens, i have tried toreinstall the drivers. It all heppened when i was using MSI Afterburner i was trying to find out some settings but then i accedentaly put the ram under 900MHz and then the problem started? I don't know if that could be the problem in this case? I've recovered my system from before i even had the card and deleted afterburner. I don't i what to do now? Should i RMA? Because i'm not the only one with this problem?

Ern88 Makes a good point, I have no doubt like me, for the sake of say £80 or more for a good know PSU branded and trusted what is £80+, Would you cry if the cheap Psu took for example a £300 graphics card out, and a motherboard of £100, people say this because more than often they made the mistake and lost a lot more due to a cheap psu popping.
Learned this lesson, and say it from personal experience. Again I learned this and it cost me far more to replace what a cheap Psu took out later. Think of it that way.

Right look at what is it telling you. Im going to tell you why it works in safe mode first of all because windows uses a stock video driver windows created it does not utilize the full power, and features of the graphics card or all of its chipset features or options.

Now in normal windows mode, it falls over because once the Ati driver is loaded it obviously as a result is using and enabling more features of the card, requiring more power draw from your PSU. sorry but is true, Look at this way what is logic telling you. PSU.

I've found out that it's the PSU but how come it working before then? And i just wanted to be sure that i didn't frye it, which i don't hope i did, but should i send it back just in case and then use my old graphics card because i can first get a new psu in 2-3 months... :s

And it's just funny that it happened after i pulled the MHz down from the RAM ?

If the system works fine with the old card the Psu can cope with the power draw of the card.
But I have to say I don`t know how old your Psu is. But I can say after a a few years use power efficiency become less to usage heat and component wear and tear, heating up expanding and contraction of example Capacitors become less efficient for example degrading over all stability and stable output over time. If you look on a Psu some will say in life hours what it expected to run before the effects of usage and time take there toll. A bit of advice Have a check of the wattage the card requires at maximum load, And check what the card is also trying to draw in amps from the 12v rail at high load or Idle.
Have a good look at the Psu and what it can provide in amps. If it is under what the card states again its the cause of the problem. Amps are just as important as wattage output.
Example.

A 7970 will draw 190 to 222w of power at full load off a 12 rail. And need a 36 amp to keep it stable from the 12v power rail of a psu. You need to take a close look at this by the sticker on the psu with its output specs.

A good 550W PSU will have 500W or more available on the 12V rail. The XFX 550W has 528W (44A) for example. Which is enough for the OPs configuration.
Also, Furmark is not a realistic usage scenario.


OP seems to be located in Scandinavia, so those particular links aren't much use. XFX and Corsair tend to provide the best value in Scandinavia, in my experience.

550 watts is barely enough and leaves little to no room for expansion. Furmark certainly is a realistic usage scenario, it's designed to torture a GPU in the same way a well written game would torture it.

It puts more load on the GPU than any game will, but less load on the CPU than quite a few games.
