For those wondering whether the i5-2500k is affected by the sandy bridge chipset bug, it's not with the current configuration, the board has 4 SATA III 6GB/S ports and 4 SATA II 3GB/S ports, the SATA II 3GB/S ports are the ones that have a 5% chance of having the issue and they are not being used. The SATA III 6GB/S ports do not have the issue and 3 of them are currently being used by the system.
