First of all yes you can flash it to the DirectCU 2 Top BIOS as it uses the same PCB and cooling. But first be sure to check if you card is stable with the clocks of the Top version.
As know as before flashing your card, overclock it to the clocks of the Stock version and try if it's stable under some games or GPU stress tests.
In the case you already flashed it to the Top BIOS then you can always flash it back to the original BIOS.
Also make sure you save the original BIOS somewhere.
