Hi, Thanks much for your answer.
I completely uninstalled everything. Even with DDU.

However, the following still happens: When no monitor plugged in on the nano, then no data in gpu-z/afterburner is shown. Once plugged in, core/mem clock + temp immediately show up in gpu-z/afterburner.
Of course, with monitor the overclocking capabilities of the core from 800 to above 900 fails and the gpu crashes.
What am I missing here?
I am using the AsRock H81 Pro BTC as mainboard. Any wrong BIOS settings? I also put the gpu directly on the MB without riser. Same result.
Btw someone else had the same issue in this thread. But no result was posted.

Let me know if you have some more ideas.
Thank you!

I have the same issue as you with my Nano. Even on stock Bios is the same. I gave up troubleshooting so I just plug in monitor Tongue

I can only think of 2 things really. Or you've not disabled onboard vga in your bios settings. Or it's the driver(which i doubt as i tested several drivers..).

Hi lawrencelyl and Eliovp,

I did many tests today- but still the same issue. First of all, you are right, lawrencelyl, this situation is even there with the stock bios. So it's not a mod issue.

I've been running tests today by running it in win7,win8 and win10. all clean installs. driver left and right. I now doubt it's a driver issue.
When core clock increase, the system gets very unstable. As mentioned, nano crashes when I increase the core clock from 800 to 900. I even tried to increase the core clock by 50mV.

@lawrencelyl : Can you run the bios mod with monitor plugged in? What are your settings in afterburner and which mem clock mod are you running? Are you on XFX?

At the beginning I thought it's due to the monitor. Or could it be another issue?
Eliovp, would a snapshot of my stock bios somehow help you to see if we now have a fundamental difference? Let me know.
I'll run some more tests next week, but not many ideas left what to try...

Cheers,
Talan

Hey Talan,

A dump of your rom wouldn't help. As it does not matter which one you use because they're all reference designs and my rom should work on any nano out there. (at the time of writing).

Again, i have a strong feeling that you guys haven't turned off the onboard vga. As that is the only way i have experienced this kind of issue in the past (afterburner and gpu-z not showing everything..)

As said before, i use 16.1.1 and 16.4.1 drivers on my nano rigs. They both work perfect, no monitor attached, everything works as it should.

The increasing of the core clock from 800 to 900 and it freezing is another story, that definitely shouldn't happen as i can raise my core clock to 1000 with an undervolt of -100mV VDDC without any problems at all.

That points out in your PSU failing for some reason, or the way you powered your risers or something.

Does your card freeze? Or does the complete system freezes and just reboots?
What exactly does it do?

Really sounds like a power problem.

You could do a register dump with AIDA64 (install it, click view, enable bottom toolbar, right click left bottom corner, video registers, ati/amd register dump "with 1 card attached to mobo") and show me that dump.
That'll explain some things as well.

In your motherboard BIOS, can you set the PCIE generation to be 1 or 2? For my MB, I set them to 1.

For my MSI motherboards i had to set them to GEN1 as well, or they wouldn't recognize all 6 cards.

For my Asrock H81 btc boards i did not have to do this, recognizes all 6 of them directly.

Greetings!
