GTX 590 + z270i

[cypress]

Good day all,

I got an mistery,
since today i got an Asus GTX590.

Already planned ahead to play with it in my ITX system.
But when i plugged it into that system and turn it on
The moniter also turns on but show for a second a "Dos underscore" (im not sure how its called in english xD).
After that it reboots. and it gets in a bootloop.

 

First my thought was F its dead. But i checked it with an older AM2 system.
and surprisingly it worked !
WIndows did'nt worked anymore, but im quite sure it isnt GPU related.

Just to make sure i wasnt crazy.
I also checked it in my main PC.
And also worked

But when i put ik back in the ITX system the problem returns.
And to make sure it isn't the ITX motherboard i put an EVGA GTX580 into it.
And the result is it works like a charm.

So no i kinda want to know why does that GTX 590 work on that motherboard.

Systemspecs are:

CPU: Intel Core I5 7600K
Cpu koeler: Corsair H100i V2
MOBO:Asus Strix z270i
RAM:Corsair vengeance 
SSD: Intel 600P 512GB M.2
CASE: Corsair Obsidian 250D
PSU: EVGA Supernova 750 G3

On an other forum some one told me it might be the CSM, that might be disabled. But its enabled.

Why do you have a GTX 590 in that new of a system? I'm just curious

[cypress]

just bored and everything in that system is cheap 
I dont want to double the value of it by buying an GTX1070 or something
the system acts as an lan pc. But when im going to an lan i switch my GTX 1070 from my main pc.
Just everything is playing with cheap hardware

yup, that means it should be able to access BIOS depending on what motherboard you're working with. Are you able to do so with the 590?

That'a lot of bumping. I would imagine that it's not compatible with that motherboard. I had this problem with a GTX 295 (last dual GPU before the 590) in some motherboards SLI would not enable and windows would crash straight away. But in other boards it was fine. That GPU had an LED that went orange when it had a problem with the Motherboard.

 

Have you tired it in another PC? An older one from the era would be better.

Sorry for the bumping.  i hope some might got an solution, but i start to think its an compatiblity issue.

The GPU Works on an Z170 Motherboard. 
On this system i updated the Bios of the 590.
 

I think it's weird that the system gives a picture but for 1 second and reboot.

But no bios.

 

An internal Speaker does not provide new or different error codes

Well that's it then. Not compatible with the Z270. Unless you can update the BIOS on the motherboard and try again then it's game over.
