Just tinkering around,I have a gigabyte GA-P45T-ES3G,Win10,running a Modified Xeon Quad E5472 3Ghz @ 1600MHZ to fit 775 board, Ballistix Sport 16GB Kit and runs OK as my back up PC. Picked up a modified X5470 3.33 ghz@ 1333mhz and installed it to try to squeeze out a little more performance , booted to the Bios, made sure the settings were correct and when it tried to go into windows it just reboots. Shows the little windows symbol for a few seconds then reboots an does it again and again. Can boot it to the bios fine but won't boot into windows??
