Solved BSOD Error dealing with SLI cards, 0x0000007E Error

[Xsorus]

I've had my computer for over 6 month's now.. When I bought it only came with one 760 GTX, so I bought the exact same one and SLI'd them together, On startup I got a BSOD... After waiting a bit and restarting the computer it went through just fine...Now for the past couple months if I restarted my computer usually I'd get the same BSOD but if i restarted again it would just fine.

Now however that does not work anymore, So far I've switched both cards out to run by themselves in multiple spots in the Computer, So i'm sure its not them..However soon as I put one in (It doesn't matter if its got power or not, If I put it in the slot I get the error) I get the BSOD on start up.

the error right now is

STOP : 0x0000007e (0xffffffffC00000005,0xfffff8000c506881,0xfffff8802d40968,0xfffff88002d401c0)

I've tried that BlueViewer program as well, It doesn't register this crash (probably cause its on startup)

It is tough to debug a BSOD without seeing the crash dump; but as the situation you are explaining, there is no option.

According to carrona.org: STOP 0x0000007E: SYSTEM_THREAD_EXCEPTION_NOT_HANDLEDhttp://carrona.org/bsodindx.html#top
Usual causes: Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control.

As you can isolate the issue specifically, the GPU, pay first attention to the underlined ones.

• Uninstall the display driver that is installed. Install any earlier version that worked good for you.
• If you have access to any other computer, apply the cards there too, see what happens. If possible, stress test the cards with Furmark in that computer.
• Plan to update the BIOS to version Version 4608 (dated 2014.01.03) from ASUS.
• Mostly any PCIe GPU should work there, but make it sure that you can use the 700 Series GTX with the board, specially using the SLI technology.To use SLI, you need the hardware to be SLI certified:
  • Motherboard
  • Power Supply (PSU)
  • Chessis

At first make these things sure. Let us know accordingly, for any sort of helps.

I found a solution to the problem....well somewhat.

For some reason, If I have 16 Gigs of my Cosair Vengeance LP ram (DDR3 1600) I will get the BSOD, until I remove one of the Video Cards.

However if I removed one of the sticks of Ram, I don't get the BSOD's anymore and can have two video cards.

I then tested each stick of Ram to see if it was the actual Ram that was bad, and its not..So The only thing I can come up with is the possible slot itself on the Motherboard is damaged some how, So I simply just decided to stack with 12 gigs instead of 16 as I probably won't see much difference anyway.

Good job!

It means, the motherboard is not capable to run with all the slots occupied, though individually none of them are bad. Recently we have seen a few of such issues.

Hope it stays stable for you.
