Hi everyone, I’m from Chile, and I have been following this topic for about two months, because I have the same issue that here is described. I have a Maximus Extreme 6 motherboard: I bought it three months ago and after two weeks of working I started having problems with my Windows time, at first I thought it was a software issue, but after discovered this topic, I realised that the problem was with the UEFI clock. I have followed all the the tips from Raja, and after the procedure the clock starts again and works well for two or three weeks but always stops again. I have tried all the suggestions described here:
• From begining I have been working with my BIOS in standard settings
• I have replace the BIOS battery
• I have flashed bios from version 0903 to 1102
• I have followed the Raja reflashing/clear CMOS method
• This board have two BIOS. I have switched between both and have applied the Raja's method again, but the problem persist
• I also changed my memories modules. I had two modules G.skill Trident X 2x8 Gb, and now I’m using two modules G.Skill Trident X 2x4 Gb
• I installed Intel(R) Management Engine Interface
• I also emigrated from Windows 7 to Windows 8, and the problem persist.
My impression is that this issue is not connecting to any BIOS settings, because I have using the two BIOS that comes with the board, and I have been always using the standard BIOS setttings and the result is always the same, the BIOS clock freeze.
Today I experienced a new clock freeze, but before this happened, I discovered something that might be interesting: A few minutes before the clock stopped, I entered the BIOS to check that all was well (because it have been passed 14 days since my last clock freeze and I was optimistic that the problem was gone), and once in BIOS I noticed that the clock was still working, but strangely the steps between the seconds were “irregular” (I made a video of the clock running in this irregular way), and after that, I left the BIOS and entered in Windows, and to my surprise the windows clock had been freeze again. After that I entered to the BIOS again and I noticed that BIOS clock stopped one minute later I recorded the video.
I’m not sure if this incident is significant, but It makes me think that clock don’t stopped abruptly, but it should experience some kind of desynchronization before it freeze.
Here I left you a link of the video if someone want to see it.
