After it is done, reboot computer back to windows and mine away. The firmware is really worth it. Prior to it I could not clock over 562mhz and only got 370GH/s. Now I am running it at 580mhz and it is getting 400GH/s at pool end. Tomorrow I will bump it up to 612mhz and see how it does. Before the firmware update I had about 10% error rate. I am barely seeing any errors now.
