So how’s she running then James – part 4
Ok, so after many failed attempts to stop my rig performing multiple boots (timing tweaks, voltage tweaks, APM etc), it would appear that I have now finally solved the problem. After much tweaking and changing the solution came via an option in the BIOS to enable (EXtreme Memory Profile) XMP. Now I dont really know what this does, but on the very first reboot I noticed that the machine actually booted imediatley none of this start stop business as before. I have been testing the machine now for over a week and can confirm that I have experienced NO failed boots or any ‘overclock failed’ messages. Yes thats right, the machine boots up first time every time, woohoo!


XMP is the inclusion of extra information on the memory module over the standard SPD data. On face value you may have what appears to be just a stick of 1,600MHz DDR3 at 8-8-8-27 timings, but a second profile on the chip includes all the settings required to tighten that to 6-8-6-24 timings.
Thanks for that, I would appear that the booting issue may be actually fixed by the change of the Base Clock speed and not the XMP setting specifically…
