ASUS P8H67-V will not detect cd-rom

[shanekm]

I have ASUS P8H67-V motherboard, SSD 250GB, SATA HD 1TB, and a CD Rom drive. There are two Gray SATA6G and four SATA3G connectors on the board. However NONE of the devices plugged into SATA3G connectors are detected in BIOS. Only when I unplug one of the HDs and plug in the CD rom to SATA6G does the CD rom get picked up. I've already tried all of SATA3G connectors and nothing gets detected. Also, updated BIOS to the P8H67-V BIOS 3506 version. I've tried both SATA Modes: IDE and AHCI in bios to no avail. It looks like only SATA6G connectors work. What am I doing wrong?

If you use win7/8.1 try update the chipset driver https://downloadcenter.intel.com/download/20775/Intel-Chipset-Device-Software-INF-Update-Utility-
Also use AS SSD Benchmark software to see which AHCI cntroller you use, intel or msahci.
