Hello,

I currently use 2 x GTX 1660 and 1 x GTX 1080 Gaming X for mining.

Both GTX 1660 run with GDDR5 and 5000 MHz and the GTX 1080 GDDR5X with also 5000 MHz.

Now my only problem is that the GTX 1080 should actually reach 35 MH, but only gets 24.5 MH.

Can it be that my motherboard is too old and does not cope with the GDDR5X, because GDDR5 goes great.

Have the motherboard: ASRock FM2A88X Pro3+

 I bought my 2nd GTX 1660 today, connected it and when I started it for mining I got this error:

CUDA Error: out of memory (err_no=2)

Device 2 exception, exit ...

Can anyone help me how to fix this error?
