Just installed the HighPoint Rocket 620. The performance is good but the card causes my machine to hang at the end of the BIOS POST. I'm hearing that it has a conflict with the Intel ICH10 controller when the Intel controller is in RAID mode.
I'm using it on an ASUS Maxmius IV Gene-Z and I can circumvent it by using the BIOS's boot menu (F8 key) to select the boot drive. I'm looking for a new card to replace it as this is really frustrating.
