I was curious to know what you found out about the compatibility of the BIOS revision for the P9X79 LE with the intel core i7-4820K. I just purchased this motherboard on the 26th of Sept and hoping it has the latest BIOS version installed. My board does not have a sticker on the bios chip. However there is a white strip with bar code and numbers directly on the board located underneath the words "BIOS". I can't tell yet if it's a sticker as I have not removed it from the static wrap. However, the last set of numbers say "4005". Any help is appreciated, I'm kind of a newb with BIOS revisions for motherboard and processor. I have the 4820 and the P9x79 and hoping I don't have to flash anything.
