Re: Gigabyte Z77x-UP5-TH "d0" post code error , help .....
The manual for your board can be located here; http://download.gigabyte.ru/manual/m...x-up5_th_e.pdf
D0 stands for CPU initialization error. the LED codes are located on pages 120-123.
Being that you are using a 2600k I wouldn't think you would need a bios update to run that CPU. Especially a beta bios... I have had to downgrade a Bios from time to time...
I'd start by resetting the cmos, on first boot go in to your bios and "Load Optimized Settings" and go from there. if you get it again, then I'd take off the cooler and remove the CPU and make sure no pins in the socket got bent accidentally when the CPU was installed. If that's good re-install the CPU and cooler and possibly try the F10 Bios... for your CPU you have to be at bios F8 or higher.
That's the approach I would use.
OS = Win7 64 Bit
CPU = i7-920 @ 3.5Ghz 168x21 cooled ba a Corsair H100

MB = Gigabyte GA-X58A-UD5 v1.0 with F6 Bios - Dead Board
MB = EVGA X58 Classified3
GPU = 2x EVGA 580GTX 1.5GB in SLI
