I went through the manual of AsRock EP2C612 WS it show that we can only install four SLI- Ready Graphics Card can you please tell me if there is a special BIOS update with the help of which I can use all the 7 PCI x16 lanes or even more than four.

Nvidia SLI and AMD Crossfire only allow up to 4 video cards to be bridged together by design. You can add 7 video cards to your board but only 4 can be SLI bridged together at 16x (meaning the 4 work as one super card), the other 3 cards will run at 8x mode as independent video cards. See section 2.6 page 23 and 24 of the manual.
