From my experience 580s are bad overclockers. I could get mine to around 830-850 but that was with voltage increases, which leaded to higher temps, etc.

I'm new to overclocking, so I've tried to follow the safest settings I can find online for my card. It's made for Overclocking and from what I read online it seems to cope fairly well with 950 Mhz (Standard clock is 855), so I decided to give it a go, but there are issues.
1. Voltage: Well, I discovered that my card runs at 1.12 mv by default. MSI Afterburner gives that as the standard setting, OC Guru too, even if it's dynamic so it moves a bit.
The strange thing is that from the review I'm reading, the 580 SOC tested online were running much lower default voltages, around 1.00. A voltage of 1.125 mv is what they get when people try to push them beyond the 900 mhz mark. How can it be? My card runs fine and it's 8 months old now, but I suddenly fear that the default voltage is too high.
2. Clock: keep in mind that my voltage is always 1.12 mv. While overclocking I didn't change it because I felt that it was high enough... So, I tried to move from 855 mhz, by steps of 10 (I'm using MSI Afterburner so shaders clock goes up accordingly). Up to 900 it seems to be fine, but I don't see a big performance gain in terms of FPS. 920 seems still ok, 930 gives me some stutters, 940 the rig crashes after 2 mins of play, 950 it crashes as soon as the game is launched.
That's a bit strange, because it seems that the 580 SOC should cope with 950 easily.
Temperatures are under control, never over the 75°C mark, so that's not the reason. What else could it be?
Here is my rig:
CPU: Intel i5 760 2.8 Ghz
Motherboard: Asus P7P55D-E
RAM: 2 x 2GB Corsair XMS DDR3
Hard Disk: Samsung HD103SJ 1TB
Graphic Card: Gigabyte GTX 580 SOC
Monitor: Samsung SyncMaster P2470 HD
Power Unit: Corsair TX650
OS: Windows 7 64 bit
Case: Cooler Master Centurion + 3 fans (enermax, cooler master)
Thanks in advance for your help!

I beg to differ, you just got to get lucky with the GPU picks.
Good example, my old GTX 580 3GB i got NEW could only hit 925 at 1.212V so i was able to back it down to 1.138V @ 79C
My Gently Used 580 SC i got now can do 1002+Mhz at 1.175V with R296 Drivers @76C And i pulled off a 1450Mhz at 1.275V on Propane @ 16C. But I'm now at 990 at 1.212V for F@H. @ 74C (F@H is brutal lol)
