Hello all, I have a problem with the caldigit fasta-6gu3 card I just purchased with the velocity solo 2 card on my 08 Mac pro. I have 2 SSDs on the velocity solo 2 as a boot drive but once I install the caldigital on the 2nd slot (1 & 2 are the only available...). Everything is running very slow on my boot drive. It takes ages to boot the mac and I wasn't even thought it won't boot at all... I ran the disk speed test and my SSD/boot drive's speed dropped to 40MB write and 200MB read, and even the caldigit card is slow too. I did a test using a 7200HDD on the drive bay as the boot drive and things back to normal/fast on the caldigit. But this would make my velocity solo & SSD boot drive meaningless. So I'm guessing that related to the PCI slots or the velocity card with caldigit. Is it because the 08 mac pro is too obsolete to deal with these two cards at the same time? due to the PCI slots 1 & 2 or their 1.1 version issue? many many thanks for reading and hope you could help giving me some helps!!
