Now that is one beast OC.. same as my 100% overclock, but im sure you can get your memory to 1700mhz.
In this case......Nothing a fresh windows install won't fix thumb.gif

en~
yeah I heard that all cards are different too. BTW I don't know it is just me or, do you feel like the graphic in game looks really bad? cuz it seems like it lack AA compare with my HD 6990 which I used to have. Also when I overclock to 1200Mhz, it start to show flikering artifacts stuff ;(

No actually ive noticed an improvement in AA from 6970's smile.gif

Haven't had a chance to finish the Phantom yet, but I did put the new 7970 into the Storm Scout. It fits (just...sorta lol). So far a little disappointed. I guess in a few months with some decent drivers it will show it's true colours, but it's hardly an improvement over my Asus 6870 at the moment. Bugs and bugs. Can't even run Crysis at low settings, massive screen corruption then complete system lock.

Edit: and the temperatures and noise are a tragedy. Running 2 monitors or any kind of O/C needs a fan speed of 50% on a cool night, more if it's hot. It is WAY louder and hotter than the 6870.

I ran the fan at 100% when doing the Batman bench, and it was about 70 degrees, the fan is actually very effective over 55%; at 100% it puts an air blast out the back that is almost unbelievable. The metal PCI plate becomes almost too hot to touch. And that's all with the side door on the scout open, at an ambient in the low 20's C.

Maybe I should have gotten the Gigabyte and accepted the heat dump in the case. But I wanted one now now now!!! haha I'm sure I'll eventually be happy, I hope.

Your rigs are amazing! Seriously full-on professional, almost military in design and construction. Really really nice.

Have a good weekend mate! :)


Cooling wise, high end cards are generally all hot and loud. In other words it really is to be expected, although this 7xxx card should be better than the 69xx cards in noise. Ever thought about watercooling? I was able to run some benches on the RC11 driver, namely Metro 2033 and Heaven. What driver are you using?

I also mounted that pump combo, though it's still very much a work in progress.

If you have the time can you please explain what the disable ULPS setting in Trixx does? And from reading a few posts it seems that people are not necessarily setting the Powertune to the full 20%. From the AMD White Paper I read, Powetune can't be disabled, because it is built into the chip itself?

How do the AMD CCC Overdrive setting interact with Trixx? I can sorta undertand the fan, one takes over the other, but not so sure about the clocks. And if Trixx sets the Voltage, is that voltage hard set into the GPU even if Trixx is closed? I can't believe they don't give any documentation with Trixx. For seven hundred bucks we didn't even get a free game (whinge)


ULPS is AMD's method of putting slave cards in crossfire into a low power idle mode. It is enabled in the drivers by default, but it obviously is only active if you have more than one card. Overclock programs cannot logically deal with ULPS. It's like the left hand does not know what the right is doing. Clock frequency wise, if you try overclocking in AB or Trixx with ULPS enabled, it will almost always result in a BSOD. Thus you gotta disable ULPS.

You're correct about Powertune, it can't be disabled. You have to be able to set it to +20 or you will hit the TDP limit sooner. It's inevitable that we will hit the rev limiter in a manner of speaking, when overclocking.

Overclocking problems occur with apps such as Trixx and AB due to Powerplay. There's three or four modes of operation, though generally its just the three, 2D/3D/Idle. If you have more than one monitor your 2D mode will change as well. Due to this Trixx/AB have a very hard time setting and keeping clocks with the bandit Powerplay running loose.

Have you ruled out Gpu Tweak or does ULPS have to be turned off with it also when in crossfire?

You only have to mess with ULPS when you are crossfired and want to overclock with a 3rd party app like gputweak, ab, trixx. I can't say that this will be true of all future apps, but the currents apps now do not mix with ULPS and crossfire well.

ULPS/Afterburner

 

The command to enable "unofficial overclocking" remains the same;

 

UnofficialOverclockingMode;

  • 1 = To keep PowerPlay active.
  • 2 = To traditionally disable PowerPlay (no Power Tune)
  • 0 = To temporary disable unofficial overclocking path.

 

Note: for single card, disabling ULPS serves no purpose.

 

 

Do it in this order;

 

Install MSI Afterburner 2.2.0 Beta 12 released

 

Disable ULPS

  1. Go to regedit (start > search programs and files > "regedit").
  2. In drop down menu: find file > type "enableulps".
  3. For ALL instances (keep pressing F3) change the "1" value to a "0".
  4. Reboot PC.

 

Enable "unofficial overclocking" HOW TO: Enable UNOFFICIAL overclocking mode in MSI AfterBurner

 

First, must disable ULPS then to enabling "unofficial overclocking". Do not override Afterburner with Catalyst installation.

Bioshock - Doesn't open (crashes)
Duke Nukem Forever - same as Killing Floor
Crysis - same as Bioshock

I have Killing Floor, and it worked excellent. Though this is the first time I have actually started it since I bought it biggrin.gif
Does it support eyefinity?

I have a little project for some of you guys with these cards under water. I want to see how low you can drop your cards vcore down while the card is clocked at 1125mhz.
I could have probably kept going but i was able to push my card down to 1.081v while running Unigine Heaven and then let it run for over 3 hours on the stock air cooling. im fairly certain that temperature has a lot to do with it, as i kept it under 70c the whole time. if the temp started rising i noticed some artifacting. i think im going to try to push it all they way down to 1.05v later(mine is a 1050mv card)

Select reset in Evga Precision and Afterburner. Uninstall them and select "no" when prompted to keep settings.

 

From Program and Feature, select uninstall Nvidia graphics driver, this will uninstall PhysX SS, HDMI drivers. Do not restart when prompted to do so.

 

Then delete these folders then restart PC.

 

  • C:\user\Program files or (x86)\ Nvidia.
  • C:\user\ProgramData\Nvidia (need to show hidden files).

 

 

Avoid using Driver Sweeper.
