Bought one of these cards, just installed it in a test machine I have - a Z77 based Intel motherboard. DZ77GA
This motherboard only comes with 2 x16 slots, and one x4 slot that can take longer cards.
Install the F40 in any other slot than the first x16, and it won't initialize itself, and is not seen by the operating system. Install it WITH an Adaptec RAID card, and the system locks up after the RAID card fully boots itself.
Anyone else have PCI-E related issues with the F40?
This motherboard gave me other problems too, like when ASPM (PCI-E power management) is enabled, the Adaptec locks up randomly) - so it might just be this motherboard. But without taking down either my main Solaris server or my two VMware hosts (all three are Dell R710's), I can't really test this in any other machine except a Windows workstation and who wants that anyway?
