Hi,
Just bought and installed a Palit GeForce GTX 1080 Super Jetstream in my system to replace a GTX960

I removed the old drivers (same version) with DDU as recommended and did a fresh install.

The issue I have is that the card seems to work fine on the windows desktop but when I run games the PC reboots as soon as the card gets under any load. (I haven't changed the settings on any of games yet from my old card).

Everything is at stock settings.

System is:
- Windows 10
- I5-2500K at stock3.3Ghz
- 16GB Ram
- Asus Z77 Sabertooth Motherboard
- Dell P2715Q 4K
- Coolermaster 850W PSU

Any help or suggestions greatly appreciated.

Thanks.
 
I have a sabertooth z77 with a 1080 and can confirm that it works fine on the latest bios. However I have a 3570K though doubt that would make much difference.
 
Thanks guys, I checked my MB bios version and it was a few versions away from the latest. I've updated it to the latest but that was still dated September 2013.

Before I did this, I tried a couple of other games and benchmarks. Some older Lego games were fine at 4K and max settings. Also, Heaven Benchmark and FurMark ran fine.

However, GTA V and Lego Force Awakens still bomb out and cause the PC to reboot.

After the Bios upgrade, the bios is giving me a message after a crash that a power surge was detected and the system was shut down.

Could this be a power supply problem?
 
Could be psu. Coolermaster have made some awful PSUs in the past. What is the exact model of your current unit?
 
I run a very similar machine (2600k & Maximus V gene )

And had 0 issues so not convinced it's the chipset.

As above, it sounds like the psu more than anything as it's crashing when under heavy loads ( lego wont stress it an awful lot even at 4k )

can you get your hands on a tester unit possibly?

It's a Coolermaster RS-850-ESBA. A bit of google-fu tells me that " the 3.3V and 5V lines fluctuate quite a bit under load".

I've turned off the under/over protection in the BIOS and Lego Force Awakens now runs. Going to try GTA V in a minutes.

Update: GTA V is running fine at 4K now. I'm a happy man! Now the remaining question is do I just leave the Under/Over Volt protection off with the existing PSU or replace it?

IMO.. The failsafes built into the motherboard were being triggered to protect your components. I would not be comfortable with my £600 GPU in a system that kept triggering voltage protection.

For the sake of £60-70. Grab a new PSU and be safe ;)

I googled your PSU, holy crap it is Cooler Master Real Power M850 850W which is 9 years old manufactured by Enhance Electronics in 2007, it have six +12V multi rails combined 120A. :eek:

It amaze your PC is powered a 9 years old PSU, the real reason your PC was shutdown after BIOS detected power surge because your PSU is 9 years old with 1 or more +12V rail had failed and other functioned rails overvolted tried to send very high voltage power to GTX 1080. But you disabled Under/Over Volt protection in BIOS mean all your PC components risk damages due to very high voltage. You really don't want to see £600 graphic card destroyed by very high voltage.

It best to leave Under/Over Volt protection enabled in BIOS and replace your aged PSU with new PSU NOW.
