Graphical glitches on new gtx 1070

[EvilGarfield]

Hi guys,

I have recently built a new pc. I have OCd the CPU at 3.8GHz and my G.Skill FlareX is running at 3200Hz (VCORE 1.30V, DRAM voltage = 1.35V, XMP disabled, RAM timings at 14-14-14-14-34) on a Gigabyte Gaming 3 AB350. Here are my full specs.
On that I have a Asus Strix GTX 1070 8OC. Now that my CPU overclock is stable (1h in Prime95 no crash), I wanted to go to GPU OC.

I downloaded MSI afterburner and Unigine Heaven and started both. However, even on non OC card I get wierd texture/polygon stretches and blue triangles. I can make them almost disappear by reducing the core clock by 100MHz. I want to overclock not underclock dammnit!

Here is a recording of it

The factory boost clock of my card is 1836MHz. HWMonitor would show peaks at 1944Hz during the benchmark (why is it higher than the factory boost clock w/o overcloking?). Temperatures are never higher than 60-65°C.


Those glitches normally do not appear my games (WoW, LoL, SCII) but I didn't try recent AAA title yet. I saw the texture stretching in Wow character screen where parts of the model would sometime stretch towards the middle of the screen.

Do you guys encountered that before?Do I have a problem with my GPU? Or is my PSU to weak (550w gold +)? Or is it possible that my CPU/RAM OC messes with the card frequencies?

Troubleshooting:
Only decreasing core clock frequency somewhat imporves the problem.

Other things tested:

• 
  Reboot
  Reduce RAM frequency
  Reinstall driver
  Reset bios

  Looks like on msi afterburner these artifacts begin with the gpu running at 2012 MHz . So it seems the gpu is clocking too high being the cause

Looks like on msi afterburner these artifacts begin with the gpu running at 2012 MHz . So it seems the gpu is clocking too high being the cause

But why is the GPU running that high even though there is no OC applied? Base boost clock is 1835, base clock 1633MHz on CPU-Z

Why is my card running at 2012MHz then?
Moreover, even by reducing the frequency by 120MHz is still get artifacts and that bring us to a displayed boost speed of 1892MHz wich is not great. I thought the new GTX were able to be overclocked quite a bit?
