Crash after 10 or so minutes gaming

Recommended Posts

Hi all,

 

I am having an issue that I can't fix. I arrived to this sub after buying Nandos 1.3 Setup. My build is: Precision M4700 with a k2000 dGPU, I am using  a GDC beast with both a 980ti and a R9 270x. My PSU is a XFX  750 watts and windows 10

 

Nandos 1.3 set up helped me resolve the R9 270x issues (driver crash every minute), so thanks for that. My current issue (that I already had with my 980 TI) is that after 10-20 minutes the game crashes, sometimes it just gives a driver crash, and sometimes a dark screen. I have tried the following:

 

-underclocked the GPU

-monitored temps (they are fine)

-tried a bunch of different drivers.

 

Has anyone been through this and can help?

@aoe2exp, have you downgraded your eGPU port to run at Gen1 link speed using Setup 1.30? If so and the crashes continue then do note some users isolated the PSU from other devices(own power point, away from other electronics like fridges/stereos) to eliminate spikes in power delivery to the video card. Ensure you are also not using th EXP GDC USB port which can also cause power fluctuations.

 

You  may even consider obtaining a PE4C V3 instead of the EXP GDC with which I was able to run a more reliable Gen2 eGPU configuration.

I experience the same problems as @aoe2exp has described above, while using a different setup. I'll try to make it as clear as possible:

 

Problem

After playing approx. 10 minutes, the eGPU suddenly shuts off, leaving either a black or blue screen of death.

 

Observing the eGPU socket, the problem occurring looks like this [10 secs video] while playing a game:

For anyone interested, here are some GPU-Z logs of these crashes:

Tried Remedies

  • Multiple re-installs of OS and drivers (also via DDU and in safe mode) (problem persists)
  • Test of possible driver combinations (Intel/Nvidia, Intel/AMD/Nvidia, only Nvidia drivers installed) (problem persists)
  • Tried changing from Gen2 to Gen1 (problem remains, while eGPU performance decreased) (problem persists)

  • Isolated PSU (problem persists)

  • Tried different chainloader modes (problem persists)

  • Tried replacing the 6-pin cable (from PE4C to GTX770) with the 6-pin cable from PSU (to GTX770) (problem persists)
  • Tried different games (problem persists)
  • Tried PE4C v3.0's "Force Power On" bypass (problem persists)
  • Tried hot-plugging (card cannot be used and fans spin on full blast, card works when plugged in when booting)

Possible Approaches?

  • Replace the PSU with a more powerful one?
  • I've read about fuse bypassing here (though for PE4H) - could that be a possibility?

Many thank's in advance!

Yes, you're PSU is insufficiently powerful to drive your GTX770. It has only 228W (12V) split across two rails.  A GTX770 will use 220W combined. So even the total is just marginal but the bigger issue is your split power.

 

Suggest use something like a Corsair VX450 which delivers 12V/33W (396W), plenty of power for your GTX770: https://www.amazon.com/Corsair-CMPSU-450VX-450-Watt-Certified-compatible/dp/B000UF28V4

... Or you could just undervolt (and later underclock if necessary) the card.

 

It is free and gives you lower temps.

Thank you @Arbystrider, for your suggestion. Luckily, I could return the existing PSU and replace it with the Corsair VS450 upon @Tech Inferno Fan's suggestion.

 

So far, I have had no shutdowns anymore! Thank you both for your help.

 

It might help others, who are looking into eGPU setups, to include what one has to look for when deciding for a PSU into the FAQ (i.e. not the total wattage, but the wattage supplied via the 12V cables, as I now understood)?

There is a reason why the Dell DA-2 is so popular: The 12V rail is the only one that matters.
