There isn't a "Best" BIOS for Quads only "Less Worse".

The only BIOS worth flashing is SoLoR's MOD BIOS 1002. But if you really want to go the official way use BIOS 0902 or 1001. These BIOS releases don't have the tRD issue that all other BIOS releases are going to bug you with.

You won't find anyone that has a Quad running stable at FSB 500MHz. It's "Mission Impossible" with ASUS boards. The ASUS Rampage Formula has BIOS issues going from MACHINE_CHECK_EXCEPTION/0X124 BSOD at around FSB 450MHz with 9 multi or above to On Die Termination at around FSB 465MHz.

For a while I thought that these MACHINE_CHECK_EXCEPTION/0X124 BSOD's are CPU related but they're not because at FSB 469MHz and MCH Read ODT 11T the problem is gone and you don't have to use more CPU Voltage than necessary.

If you ask me. I think that the problem is more "ASUS Engineer" related because they think they are so smart but they don't know how to fix these issues.
