GA-X79-UD3 with Intel i7-3930K not keeping time on Win 7 x64

[slalom]

Hi, this is my first post here
A couple of months ago I bought this used m/b & cpu

The PC has trouble keeping time on wndows 7. I tried the following

• Changed the battery
• Fresh install of Windows
• Re-flashed the BIOS F20
• changed time-servers

Any suggestions?

Greetings,
Failed CMOS battery and/or incorrect time zone settings in the OS are the most common causes of this behavior.

I DID change the battery, and time zone is correct

Anyone has any idea why this is happening?

Anyone has any idea why this is happening?

Is this system on a domain, a network or getting time from a NTP server?

Does it connect using VPN to another network or domain?

Your modem, router or ISP might also be affecting this.

It's on a workgroup, a home computer
There are no VPN Connections

Router's time is correct

Is there a setting in BIOS that could be affecting this?

Ok, I found the fix a few days ago

I went into BIOS and noticed the clock was frozen, it should be counting. So I googled "BIOS clock frozen"
One of the results was this page

So I did what one guy said

Code: [Select]

Re-flash the latest UEFI, and clear CMOS with the board in standby (this will reset the management engine). See if that helps
and it's been working ok for a few days now

Greetings,
I want to be sure I understand,

You said you had re-flashed the BIOS in your initial post.  This did not help. 

So essentially, you performed a CLR_CMOS when the system was in standby and after waking the system, the RTC was keeping correct time.

Is that correct?

I re-flashed it a couple of months ago, but as the post said, it needed a CLR_CMOS too. I didn't do that.

The right thing is, re-flash the BIOS and then CLR_CMOS with PSU on (Power supply on but the system off)

And then the BIOS clock was working again
