Tested my FE a bit more.
Stock Time Spy score at 19,560.
Stock Time Spy Stress Test frame rate stability at 97.5%, average boost 1770-1785 with temps stableat 70c, power at stock 350W. Fans stable at 63%, which is very much audable for me. voltage around 920-950mv.
Th is is defnitely a lower end bin chip. Sad times.
Stable undervolt at 862mv @ 1800, which draws about 300-320W of power, improvies stability to 99% in Time Spy stress test and brings fans to around 52% at stable. Gets a timespy score of 19,400.
The card does not overclock at all, breaking 20,000 timespy score, which seems to be average, even at 100% fan speed is impossible for me (without memory oc but god knows how to test for errors there as normal benches dont show error).
A bit annoyed that I lost the bin lottery on a £1,400 card.
