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, 3DMark and Unigine Heaven. I first launched Unigine for a non OC run to benchmark my base performance. 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 wanted to overclock not underclock dammnit!:rolleyes:
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.
Decreasing memory clock doesn't seems to do anything. Reducing the core clock well below factory default can somewhat solve the probelm
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. The texture stretching is visible in 3DMark Firestrike but less important. I think it's because unigine heaven 1440p stresses the GPU much more than firestrike 1080p
Do you guys encountered that before?Do I have a problem with my GPU? Or is my PSU to weak (550w gold +, my system draws 290W from the socket under load))? Or is it possible that my CPU/RAM OC messes with the card frequencies?
I am thinkin on RMAing
Troubleshooting:
Only decreasing core clock frequency somewhat imporves the problem.
Other things tested:
Reboot
Reduce RAM frequency
Reinstall driver
Reset bios
