looks like your mobo has six SATAIII ports.

my understanding is that it's possible that your existing SATA cable could be fine to support 6Gbps speeds, or it might not if it only marginally met SATA II standards to begin with. so see if it works at 6Gbps and get a new cable as needed, or just buy a new cable now (they're not expensive).
