Well according to this website: http://global.msi.com.tw/index.php?func=prodcpusupport&prod_no=166&maincat_no=1&cat2_no=171&cat3_no=6#menu
No. That maybe an incorrect assumption though. I would fire off an e-mail to their support and see if it is. It seems the latest BIOS was released early this year, so you maybe out of luck. Or you could get lucky and it's not being listed is an oversight. The problem is that if the microcode hasn't been updated to recognize that CPU, the board will likely refuse to POST.
