I have the following system :
I am having a very peculiar issue. When I overclock my I7 920 above 2.8GHz my computer enters a weird reboot loop (it reboots 3 times before it posts). I will explain this in more depth : i enter bios, select my overclocking settings, choose XMP, set the appropriate voltages, save, exit, computer shuts down, applies overclocking settings, turns back on, reboots once, reboots the second time, reboots the third time, post message with my new frequency. This problem has been occuring since November, aroudn the date where I tried to register on this board. I have been troubleshooting ever since :
1. Memtest+ on RAM
2. Asked advice on XtremeSystems
3. Tried 20 computer boards
4. Opened up my system on multiple occassions
5. Contacted Gigabyte and they provided feedback.
Today, after months and months of issues, I made a breakthrough. I will attach 4 photos. The first photo, will show my BIOS where my PC is at stock with a x21 multiplier. The memory speed is rated at 1333MHz. The second photo, will show my BIOS post with my I7 rated at 2.8GHz and memory rated at 1333MHz. The third photo, will show an overclock to 3.5GHz. In the same photo you will see that in the BIOS, my memory multiplier has been reduced in order to keep within the rated speed. The photo will show that my memory speed is at 1333MHz. The 4th photo, will show the BIOS POST with the 3.5GHz settings. As you can see, the memory is not at 1333MHz but at 1328MHz. Why did photo number 3 show 1333MHz and photo number 4 1328 MHz? Could this be the issue? Does the motheboard detect this difference in speed and performs several reboots before it boots normally?
