[H] users 7970 Overclock Results thread

What are the best programs to monitor the GPU temps, etc? HWmonitor only shows one of my cards.
 
Sapphire 7970

1125 core
1575 mem
0%
Stock Volts
55% Fan Speed
75c load


1200 core
1625 mem
+20%
1.187volts
55% fan speed
83c load

^^ Nevermind. Not stable at this speed during gaming.

Having trouble getting CrossFire to work. System keeps crashing and GPU-Z shows the 2nd card is running at 32bit and only 22MB memory bandwidth. :( Not sure if it's accurate though.

I don't know if it's a heat issue or a power issue. I have a Corsair HX750w PSU.

Well I was using CCC to overclock. Are you saying set to -20%, run Furmark, then do the OC and set it back to +20%? The purpose of the powertune setting is that it limits the amount of power draw the card can have...it doesn't necessarily guarantee a change. Doing that would just cause the card to turn off wouldn't it?

Set to -20% run furmark and see if it runs without any issues, then set it to +20% and run again. Then overclock and run again.

For some reason I simply can not run anything with Afterburner or TriXX it totally screws my system all up, as soon as I run Furmark I crash and the videocard seems to power down. I can even underclock the card in either of those or overvolt it it does not matter if I mess with either in any way I have to do the powertune thing to get it working again.

Damn if I know why. Once I have it working it works 24/7 no issues at 1050/1450 at stock volts. I get crashes at 1090+ on the core.
 
d/l'ed TRIXX and I thought this was pretty good:

1275/1500@1.2

but wait till you see this:

105870/1500@1.2v

looks like it's not actually doing anything? was bumping it up 25MHz at a time but after I got to 1500 with 1.2v I decided this thing was broken. First thought something was up when I noticed the FPS weren't going up at all no matter what clock speed I set in TRIXX... any ideas?
 
So I have the XFX BEDD. What are you guys using to monitor temps? I get to around 75c in BF3 OCed to 1125/1500. Furmark always maxes out at 90, even if using stock clocks. That seems odd to me. If I crank the fan to 100% it will still crash (at least when at 1125/1500) after about 7 minutes...crashes at around 87c.

Go back into Trixx and set your 1250 mhz. Then go into GPU-Z and see if the clocks match.

You can also open Overdrive and look at the bottom (do not change any options or touch the sliders), but you will need a 3d load on the card.

If the clocks are applied correctly, you will see 1250 mhz in overdrive, at the bottm, even though the sliders won't show it.
 
Found that I'm stable at 1150/1575 and stock volts. I will NOT destroy my card by testing furmark.

Yeah I think I'm done with Furmark, it seems to do very bad things. I'm stable at 1125/1500 with 60% fan speed (XFX BEDD) in BF3. Gonna go for higher memory tomorrow.
 
At first it was pretty awesome seeing the OC headroom when he was around 1200, and even 1300 on the gpu. Then he started posting 1500+ on the gpu and memory above 2000. The one before the link I posted was around 3385/7678.
 
I know 1150 works on my sapphire in Trixx since Gpu-Z and CCC show the new clocks, and my FPS goes up by 2 in Sacred 2 (compared to 1125).
Looks like I can pass 1175 mhz in 3dmark '11 and Vantage, BUT causes artifacts in planes in BF3...1150 is just perfect, though....not bad for stock volts!
(Edit) Heaven 2.5 as well runs fine at 1175...but 1150 will be my max game speed...wonder how much i could do at 1.2v...

With regards to memory overclocking, how are you all checking to make sure you didn't push it too far and are running into the ECC?

Set the core to stock and keep moving it up 25 Mhz running benchmarks till you start getting negative returns then move it back down.

anyone have a recommendation for the 'quickest' benchmark? overclocking can be a time consuming thing i know, but i'd like to not sit through 30 runs of Heaven if it's not necessary. back in the day i used Kombustor and just waited for my fps to decrease instead of increase...but i don't particularly like stress-test tools like that.

The Metro 2033 benchmark tool is pretty quick, but it seems to vary a bit from run to run. It's about 60 seconds long. It will calculate averages for you which is nice.

Who says you HAVE to run 30 runs of heaven? Just do whatever you want and enjoy your computer and play games. 30 runs of Heaven is like running 50 runs of LinX/Intel Burn Test...completely, utterly unnecessary.
 
Porter_ said:
i prefer to use gaming as my stress test, it hasn't failed me yet. you'd be surprised at how different games apply load to your gpu in different ways. right now my card is BF3 stable all day long but not Crysis 2 stable. Crysis 2 may be considered a terrible game yadda yadda, but holy hell it looks good with DX11/high res texture packs. it's a great way to test out your new 7970.

you're preaching to the choir. '30 runs of Heaven' was referring to every iteration of mem clock testing going in 25MHz increments, and i was being a bit tongue in cheek by saying 30 runs. testing mem overclocks is trickier with error correction memory. you can't exactly load up BF3 multiplayer each time and look for a decrease in performance, at least not accurately. Ghoststalker's suggestion of the Metro bench is a good idea.
 
stalker: Call of Pripyat is a good stress test too, and its free even if you dont own the game.

ah i see. Thought you were trying to do the "run prime 8 hours version" :p
I just set my memory at 1575 mhz and left it there.

I'm also finding Furmark to just not be a very good test of stability.

I can run Furmark all day at 1125/1575 at 1125mV with no artifacts or other issues, but fire up a game and I start getting artifacts almost immediately. Needs a bit more voltage to get rid of the artifacts in games.
 
With these cards I think its safe to say it would be faster to just max them out then go 25mhz backwards till your good. I can't believe I'm saying it but I am
 
Good thread! I have one suggestion as an add thought. Can folks include the method as to exactly how you are getting your overclocks? Example:

Are you using CCC to max power control to +20 then using another program like afterburner, Trixx, ASUSTweak, etc. to set the voltages, GPU and Memory clocks as well as fan profiles?

Myself, on my xfire MSI 6950's I had to flash them to and ASUS BIOS with unlocked shaders. Unlock the higher clocks with smartdoctor but do the actual overclocking adjustments in CCC. Then set custom fan profiles in Afterburner. Sound like a Pain? It was. But that was the only way to get stable OC's without CCC and other software being at odds with each other.

I'd like to know how you guys are getting your clocks done specifically. I'm hoping ASUSTweak or something like that can be a 1 stop shop after setting CCC to +20%.

Thx in advance.

I cannot mess with any of those programs without my videocard crashing bad. I can open it but if I touch voltages, mhz (up or down), fan profiles, etc It dies after 5 seconds everytime.

Have you figured this problem out? Turns out even after upgrading my PSU I'm still having similar issues, driver crashing when overclocking. It did fix my system shutdown issues though. I'm in the midst of reinstalling 7 right now though, the CCC was acting kind of funny and I suspect there were driver problems.

Nope, only thing I could come up with is the powertune to -20 then +20 and never touch any of those programs again :p

I can overclock fine in CCC

I was having the weirdest issue with CCC, I would move the power slider to max, hit apply, it would blink then go back to default. Wouldn't take at all. Should have my box back up and running in 30 minutes, lets home the fresh install resolves some issues.

after monkeying around in afterburner a bunch, i started getting the same issue. i uninstalled AB, uninstalled drivers, rebooted and reinstalled everything and all is well.

Hrmm. It happened to me before I installed AB, though at that point rebooting *seemed* to resolve it temporarily, but then it would just happen soon after again. After installing AB, nothing would make it work. I'm not convinced it was ever actually working though, considering the crashes I was getting at relatively safe temps.
 
Got my 7970 yesterday, and it wont run Heaven 2.5 even once in windowed mode without hard locking the sytem, and thats without messing with the clocks in CC. :eek:

In full screen mode it doesn't seem to have any issues.

My 3dmark Vanage score with stock clocks is 24659 using whatever settings come with the free version. Lowest score I've seen anybody post for a 7970.

My old card was a GTX295, so I know my power supply is capable supplying more than enough juice to this sucker.
 
ran heaven overnight at 1125/1575 +20% powertune. no issues to speak of. everything looked great this morning, no artifacts or lockups. :D

im pretty satisfied with the eyefinity performance of this card at these clocks. not sure if i even wanna bother o/cing more.

eh, there's probably some driver kinks for AMD to work out.

In the "New Drivers" thread someone said there's been crossfire issues with the downloaded drivers from AMD's website that aren't occurring with the drivers from the CD. I'm going to use the CD drivers now....
