Display driver crashing in DirectX 11after Overclocking GTX 580 Twin Frozr II

I have several GTX 580 Twin Frozr II OC in SLI. The nvlddmkm.sys appears to collision and restart when about 10-15min on gameplay on DX11 amusements (I have perceived it happen in F.E.A.R. 3 and Crysis 2 DX11). I have not had any issues with alternate games (I haven't played any viable DX11 amusements), and surprisingly, it hasn't happened on Heaven benchmark (DX11) either, for some explanation

Configuration:

• Core i7 2600K @ 4.5Ghz (Vcore:1.35V | Mult: 45)
• Corsair Dominator GT 8GB @ 1600Mhz, 2 DIMMS (1.6V, 9/9/9/24)
• ASUS P8P67 Deluxe
• Corsair HX 1000W
• 2 x GTX580 Twin Frozr II OC (not overclocked above the factory overclock)
• 300GB Intel 320 SSD
• 500GB WD Black Caviar
• Windows 7 Ultimate x64
• Single Monitor

The BIOS for the cards is up and coming, so are all drivers.
The voltage for both the cards was 1025mV. I upped the voltage to 1050mV (utilizing Afterburner) and I haven't had any issues forasmuch as (played Crysis 2 DX11 for a couple of hours). Might that have been the issue? Since in this way, how do I forever set the voltage to that quality? And then why do I need to do this in the ahead of everyone else?

Had the same situation when utilizing simply one of my 580 twin frozer II/oc in F3ER and Crysis2 in dx11 at stock specs but running at 1038, 823, 1646, 2138 plays both like margarine with virtually no slack whatsoever.
I just utilize one card when playing at 1920x1080 (ultra) but both when going 5760x1080 which was playing fine on stock specs (quite heightened) via sli/3x24" for 2d surround.
I'm still utilizing 266.58 in light of the fact that 275.33 broke gta4 @ 5760x1080 for me and I can’t go without gta4 (cherish that game).
Sounds strange its great to see I'm not the one exclusive and these discussions are here to get help, one of the explanations I like MSI stuff.

Also, do you know how to flash new BIOS with different default values? I rather not have to set Afterburner to auto startup. Follow the below steps:

• - download NiBiTor v6.0 or above
• - save your bios by GPU-Z
• - open saved bios in NiBiTor and go to Tools/Fermi Voltage
• - change voltages Setting 2 and 3:0 from 1, 0250 to 1, 0500
• - change voltages Setting 2 and 3:1 from 1, 0750 to 1, 0880
• - click Apply
• - save bios named gtx580.rom
• - Than you must flash this bios on the card, you need bootable USB disk – (You can use Internet for further help)

In the event that you have bootable USB and have replicated right documents for nvflash, restart pc, and get to boot from usb

1. -in DOS mode compose the proposed charges: nvflash--protectoff for unlock security before glimmering and the second summon is nvflash gtx580.rom (name of spared bios)
2. -view in advancement and at the succeed close, restart PC
3. -beyond any doubt in windows, reinstall driver for card

When a DX9 diversion is fixed to a higher DX form, in this case DX11, a voltage include might as well be combined in the patch so when the patch is instituted the voltage include is similarly established. In Crysis 2's case, no voltage was incorporated. That would be why it slams. They possibly avoided it since. They weren't beyond any doubt of every thinking individual's voltage necessities. They would have liked to location a situation but made a different situation in the course of action.
