Crossfire problems 2x r9 270x

[Boss Skillz]

Hello there, recently I uprgraded my build with an extra r9 270x with all drivers installed. But i get performance drops instead of improvement. Why is this?
Specs:
Amd fx 8320 stock clock
2x r9 270x
600 w corsair PSU
8 gb RAM
1 TB srorage
Gorsair h80 cpu cooler

Drivers removed and installed after new card installed? What motherboard? CX600 is a little light for that setup!

Check that both the cards are running at the same Gpu speed in Mhz and also the same Memory speed.

In your windows power options make sure you have a balanced power profile selected.
Make sure the power saver option is not ticked.

Or setup a power profile so the system runs without any power saving options selected.

Or !
In the advanced power options set the mode to High system performance.

Click apply, or ok.

Restart your system and see if the performance improves for you.
