Gigabyte GA-P67A-UD3 - Windows 7 64 bit freezing/Locking UP

[jakakxl]

what settings did you change? anything related to RAM?

[fuzion23]

Everything was stock.  Came to conclusion it was either a bad board or memory.  I haven't got the chance to overclock

Interesting to see that RMA seems to have worked for you.  My machine made it through last night without a problem.  I'm starting to get optimistic that my BIOS settings have finally clicked.  I'd rather not go through opening this rig up and pulling everything out if I don't have to.  Will post later today what settings I'm currently using.

Well at least things are looking a bit more hopeful for both of you.

[DemoniK]

looking forward to seeing what settings you change omnidragon.
still struggling here with my UD4...
It got through last night, but I powered down and re-added my capture card and it's unstable again. removed the card and it's still unstable. The only other thing I did was install a 3rd party firewall - and yes I've tried removing that too....

At this stage I'm convinced it must be the board/BIOS itself... I've put everything into my 1366 system and it's stable (although I can't quite put in exact same config).

Also had issues with F7B - for some reason after a few resets I will get a BIOS checksum error and be pushed back to F3. So have stopped at F6 for now.

I've run memtest twice on every DIMM stick, once separately, and then 1 by one adding to the system.
I've disabled LAN and Audio in the BIOD to no avail - they are both now back on so at least I can enjoy them when the system doesn't idle.
I've also disabled Turbo Mode, USB3, eSata3 and removed some of the wake events.

Is very frustrating - only happens when it's idle - and nothing in the logs.

It would certainly seem like it was the motherboard that was at fault in  your case.

Hmm... the fix that guy gave me worked.

I flashed the BIOS to F7F and then downclocked the ram to 1066mhz.

So far 2 days no freeze yet.

Thing is with these new boards and BIOSes there are bound to be problems and even though it can be annoying it is the price we pay for being early adopters of this technology. I am sure it will all be ironed out within a matter of weeks.

My machine made it through another night so I went and looked at my BIOS settings.  What I changed (that I can remember) is below.  I started with the Optimized Default Settings option and then set the following:

Extreme Memory Profile - Profile 1
  All settings on Auto, Turbo
H.D.D. S.M.A.R.T. - Enabled (was disabled by default)
Init Display First - PCIEx16 (used PCIE)
ACPI Suspend Type - S1 (was S3)

From what I can remember, those are the things I changed from the defaults.  Everything else seem to be set to Auto (if it could be).  Another interesting thing is the board seems to be automatically determining 1600 as the speed for the RAM now though it didn't do that when I first got it.

I'm hoping to let it run a few more days before I attempt to overclock anything.  Hopefully these setting changes make sense to someone.  One other note is that I chose the optimized defaults, let it run for a while (until it froze), and then came back and changed the settings.  So, in essence I changed only a few things each reboot.

Everything looks fine in your settings apart from the XMP setting. Unless you purchased memory that was specifically designed for the P67 boards by using the XMP it will increase the memory voltage to 1.65v which is over what this board will be happy with. It would be safer to write down the XMP settings in the BIOS and then turn off XMP and manually apply all the other settings apart from the voltage.

[jakakxl]

Seems like it's the ram.

[Dark Mantis]

Well most of the memory being used on these board  was designed for the X58 motherboards and is not ideal for these . There is more gradually coming onto the market amd so it should sort itself out.

[omnidragoon]

Hm, I'll change those settings in the BIOS and see what happens.  Will post the results.  Since my RAM was found in the "good" RAM list I wouldn't expect that it would be incompatible.

[Dark Mantis]

It's not exactly a case of being incompatible just may not be perfect.

[omnidragoon]

So I went to change the XMP settings away from Profile 1 and back to Disabled, but I noticed that the voltages for the RAM was already set to 1.5v.  Looking over the rest of the settings they all seemed accurate for my hardware so I decided to leave them alone.  I'm going to let this run for a few more days and see if it freezes.  If not then I'll assume that all is well and begin overclocking.  Hopefully my posts have been helpful to someone.
