So I have had a HighPoint 644 SATA III 6.0 GB host card in my system for some time now, and yes, it was a total pain to set up when I initially installed it. I recently picked up a new 3TB SATA III 6.0 GB drive (newegg had uhm on sale) and I had a spare HighPoint 620 SATA III Host / RAID Controller card laying around (and a spare PCI-E slot to boot) so I dropped the card in, mounted the drive, and wired it up, using a SATA III 6.0 GB cable, of course.
I then tried to boot it up - <insert /facepalm here> - yea, I got nothing.
Has anyone else successfully gotten a HighPoint 644 and a 620 to co-exist on the same board? (It'd be even more ideal if said board was a Gigabyte MA790FXT-UD5P.)
I've noticed that during boot up the system is seeing the newly installed card before the primary card, since the bootable disk is already on the primary card, the next step will be to switch the ports that the cards are installed in and see if that makes any difference. There's nothing in the board docs about one PCI-E slot being initialized before the other, but it's worth investigating. Will post follow ups (especially since I have read that HighPoint support is non-existent).
Using the onboard ports so that I can still use the new drive, but sure would be nice if I could take advantage of those fast I/O rates that come with SATA III.
