GTX 580 SLI Problem

post #1 of 7
Thread Starter 
I recently picked up a second EVGA GTX 580 and here is my current setup...

i7 970 stock
Asus P6X58D-E
2x EVGA GTX 580 stock
Corsair XMS3 6GB tri, CL7 @ 1600MHZ
2x Vertex 30GB Raid 0
X-Fi SB Titanium
Corsair TX-750.... Will upgrade to Corsair HX-1000
Antec Twelve Hundred Case

Ever game runs perfect... Crysis is finally playable at 4X AA, enthusiast @ 1080p and can leave V-Sync on and min frames are around 50... Loving it...
Also Metro 2033 @ 1080p with 4XAA, DOF Enabled, and Physx gets me around 45 FPS average, with the extras off is 75 FPS...
Heaven 2.5 at defaults at 1080p get me 105FPS...

Games run perfect obviously, but 3dmark11 is what is having issues...
I am on the beta 270.51 drivers...
Running performance setting runs just fine and I get over a 10K score...
On extreme, I get 3440...
While running on extreme, there is stuttering going on. Is this what they call microstuttering?
Its not as smooth as the frames seem to jump from like 20 to 22, then back to 20, and back and forth...
So the gameplay just looks unbearable, as it lags then gets smooth then back to lagging...
I checked the temps and they were obviously different. Both cards sit right next to each other as I do not have an SLI connector long enough to make the space...
Top card reached 88C and bottom was 81C under load.
Could the temps be why i'm experiencing these slow downs? Only is happening in X-3dmark11
Or could it be my PSU not providing enough power?

Anyone else with the same setup experiencing such issues?

First go here and fill in you system so everyone can see what you have easily.

The temps def are not the problem, 20 fps is pretty juddery anyway, is the game actually "skipping" or freezing for a moment?

Are they downclocking at all? Can you see if the core speed stays the same in afterburner while the test runs?

Im running GTX 580 SLI , and i have no issue
by the way in metro 2033 I get 69fps plus at very high setting with 16AF and 16AA PHYSX ON.
CRYSI 2 in extreme setting 120fps
in 3DMARK 11 I got 12992 points
Bad Company 2 at high setting with 16AF and 16AA---147fps

your problem could be your power supply 750watt
5.2ghz

crank up your fan..your cards are throttling due to the temps..once you hit 90c your cards will automatically drive down the clocks to cool itself..

if your OCing all your stuff while gamin the PSU might also be peaking out..you should at least have an 850w or more for your stuff..

temps are too high. they start downclocking at those temps and will shut down if it goes 90c+

Thanks all, I seemed to have figured out the problem. 'Nvidia Power Management' being set to 'Adaptive.' After setting this 'Maximum Performance,' No more slow downs. Note this was a constant lag every 2 seconds, like one card was running slower than the other and it would switch between the two cards every two seconds... I experienced this same problem with my GTX 295 when I didn't dust it out...
I thought 88 C was good or average? Anyways no more slow downs and I am getting a X3737 score now....
I am definitely going to upgrade my PSU to a HX1000 as I know this PSU is walking on egg shells now.
I don't ever touch any fan settings because everything is stock except the RAM which is controlled using XMP... Thanks all and make sure to set the Nvidia Power Management to Maximum Performance especially to SLI owners... Nvidia's drivers resets it to defaults to 'Adaptive'.

88c is not bad at all - look up 580 temps and you will see tons of people who fold on their cards at 90-95c 24/7 (that is too hot for my taste, but not at all bad for the cards). Fermi's can hit 105c, but I like to see my cards no higher than 80 when folding.

Watch your core clocks in afterburner and see if they stay up or downclock at all and you should be good. I had to do the same thing with my old 460's when playing WoW in windowed mode, they would always drop from 900 to 405 unless it was set to performance.
