Hardware & Technical HELP with GTX 970

[Donald Duck]

PROBLEM SOLVED!

Hi and thanks for your efforts to help.
Sorry for the late reply.

At the end it turned out that the heat-conductive paste on the CPU had dryed out and had to be renewed. Due to my motherboard settings it would not switch off the CPU but slow it down when overheating, which affected the GPU output.
So I put new paste and it works perfectly now, meaning ~120 fps in borderless window mode on 2 screens.

After realizing that this might be the problem I used the little tool Coretemp which confirmed my suspicion. Now the CPU runs at 60°C when playing ED .

Fly save & thanks again!

Nice to know you fixed it. Wonder why it only happened on switching the cards over... maybe you disturbed it during the fitting? From the CPU type, I'm guessing the PC is perhaps 3 or 4 years old?

Right, 3 years. I even found a note to myself that should have reminded me to put new paste end of 2014.

Well the performance with the 660 was much better after putting the paste as well. And since the 970 is using the CPU in a higher way the system "broke down" when installing the 970.
Anyway, now its working fine.

Complete waste of money, a single GPU system will at most require a 600 watt PSU.

It is always advisable to have more volt · amps than you need.

With a 600W PSU, you already have plenty of spare energy unless you are running old GPU's or more than one. My eldest's computer with i3 CPU, 16GB RAM and 970 GPU runs quite happily on a 450W PSU. It now has even more spare energy because I removed the suspect DVD drive and gave him the USB external BlueRay player with instructions to only plug it in when required. i.e. about twice in 6 months.
