Gigabyte GA-M59SLI-S5 (Nvidia nForce 590 SLI)
Board Revision: 0.2
Installed BIOS: D3 (12-05-2006)
Upgraded with: F8H (05-21-2007)
We found it hard to believe that there was a BIOS with official Phenom support for the mainstream motherboard GA-M57SLI-S4, but not for the GA-M59SLI-S5, which targets the enthusiasts community. The platform comes with a four phase voltage regulator and it even features a powerful heat pipe solution (Gigabyte Silent Pipe) to cool the voltage regulators and the chipset components. Gigabyte also added lots of SATA ports, Firewire and all the goodies an enthusiast expects. We also found it great to see that there is a third x16 PCI Express slot - although the chipset only has four lanes left to power it. We're confident that Gigabyte will follow up with a BIOS enabling Phenom support for this motherboard soon. At this point we weren't able to run Phenom on this motherboard.
