The Intel P55 Express chipset had an issue that caused iPhones unable to sync. Gigabyte has issued a BIOS update fixing the problem. The Intel P55 is Intel’s latest midrange chipset and is for Core i5 and Core i7 machines. The other two P55 motherboards, ASUS and MSI were also affected by the bug and there is an update for ASUS BIOS but it’s not the official fix. Hopefully both ASUS and MSI quickly update the BIOS to fix the issue.
