Most AM2 Motherboards Not Phenom Ready
Test Results
Asus Crosshair (Nvidia nForce 590 SLI)
Board Revision: 1.04
Installed BIOS: 0702 (2007-06-20)
Upgraded with: 0904 (2007-11-08)
The M2 Crosshair, being an enthusiast motherboard, has received multiple new BIOS versions during the last months. We downloaded version 0904, which adds Phenom support, adjusts Cool'n'Quiet support, bringt an improved CPU auto-detection algorithm and AGESA version 3.1.3.0 (AMD Generic Encapsulated Software Architecture).
The BIOS update worked: While it was not possible to start this motherboard with Phenom using the initial BIOS version 0702, the board recognized the Phenom 9600 and worked properly with BIOS version 0904.

spearhead too many vendors boycott the upgradebility they just dont want to release a simple bios update because they want to force costumers to buy a new motherboard. it would anger me i would have bought a am2 motherboard and the vendor was such a bastard to boycott the upgrade.today those bios updates are rare too find. so far i have only few vendors who upgrade there bios. apperently ASUS support it the best so that is why i will choose ASUS above all those cheap bastards from now onReply
