GIGABYTE GA-MA790X-UD4P - clock loses time

[johnnyasia]

I RMA'ed a GIGABYTE GA-MA790X-UD4 last week.  It worked for 2 days then stopped loading Windows and wouldn't boot from CD. I returned it after following all steps recommended by Gigabyte tech support without any results.


I replaced it with a  GA-MA790X-UD4P, Windows loaded and it worked perfectly. BUT, the clock loses
a couple a minutes or more daily, with the PC running or when it's turned off.  Is this a cause for concern?


Here are the components:

 I just found this post:


"system time is incorrect"
http://www.msfn.org/board/lofiversion/index.php/t68913.html


 "the time in the bios is correct, it is only when i go into windows xp x64 that the time becomes incorrect."

  "yes i do have xp32-bit installed. the time is always correct on that sytem. it is only an x64 problem."



Maybe my time problem is an XP 64-bit glitch?

Hello Johnny

just try it only with bios without entering windows, then you will easily see if it's motherboard or OS related problem

Hi,  I checked in BIOS and the time was OK.  Thanks, it must be on OS issue.

Oh well,  the clock problem got worse, and when I checked the clock in BIOS it had lost 15 minutes overnight.
When I started the computer it wouldn't boot up at first, no beeps, just black screen. I had to hit the reset button
a few times to get it to boot up. I RMAed the board.


That's 2 mainboards in a row I've had to return. I have been building PCs for over 10 years, for myself and others.
I have never before had a problem with a mainbaord, I've used Abit, Asus, FIC, Epox, and MSI boards. I
am wondering about the PSU, but it's supposed to be a good one. And, a faulty PSU wouldn't affect the
mainboard clock, would it?

A faulty PSU could do all sorts of stuff, fluctuating currents can damage the board, ram, cpu and gpu if it is faulty. What PSU is it? You can monitor the outputs from the 5V and 12V rails in the BIOS I believe, and how far away from what they are supposed to be can be an indicator of condition of the PSU. Another sign is random reboots/restarts, especially with load on the cpu or gpu such as in games.

I have only had one board not work, and that was a Asus 680i.

I did monitor the 5V and 12 V in BIOS, the values were very good, and there were no fluctuations, very steady.
I didn't have any random reboots, and I ran Everest, Sisoft Sandra, memtest86+ and other benchmarking & testing software, everything was OK. The problems began a few days after I built the system, the first thing I noticed was
the clock losing time. Then it got worse, and this morning the PC didn't start up, no beep, then it started after I hit reset a few times. I went right into BIOS and saw the clock lost about 15 minutes since I turned off the PC last night.

I think I'll get a new PSU and use that one with the replacement mainboard. Maybe 550 watts isn't enough for my system?? I thought it would be sufficient

I'm going to switch the PSU to this one:

I also had a problem with a GIGABYTE GA-MA790X-UD4 mainboard, I returned it and got the  GA-MA790X-UD4P, which I returned yesterday,  the GA-MA790X-UD4 had been discontinued at Newegg, less than a week after I bought it. 



It worked fine for 3 days then I turned it back on and I got this error during post:

'Verifying DMI Pool Data............
WARNING: EES is turned off !! Please use EES application to turn it on again. Press any key to continue'



Nothing happened when I press a key. I cleared CMOS, loaded fail-safe
defaults in BIOS, that didn't help. I took out the RAM and reinstalled it as
per Gigabyte tech support suggestion, it didn't help. The same error
message appeared without any drives attached, after I disconnected them. 


 Also, when I hit F12 to go into boot screen the computer
 froze up and I had to use the power button to turn off the pc.






I found someone else with the same problem with a Gigabyte mainboard:

POST error preventing boot-up

http://www.techsupportforum.com/microsoft-support/windows-vista-support/351911-post-error-preventing-boot-up.html


I seems to me the PSU is the prime candidate, after 2 boards crapping out after a few days.

The replacement mainboard arrived, I also replaced the PSU with a 750 watt Corsair. The system
 booted up, I tweaked the memory settings, checked the voltages and all looks good.   Windows loaded
just fine, I'm running memtest86+ right now.

Knock on wood!  The computer I'm on right now needs a new southbridge fan and it started making lots of noise
about an hour before UPS arrived with the mainboard. Hopefully the new mainboard and PSU will
do the trick, then I can replace the southbridge fan on this one.

Oh no, the clock has already lost 3 minutes in the 4 hours since I rebuilt this.
New mainboard, new PSU, hopefully this is just the XP 64 bit time problem.
I'll know soon enough.

 

[johnnyasia]

Phew, everything seems to be ok with the new mainboard and PSU, the clock loses time in XP 64 bit, but not in BIOS. I ran memtest86+, CPU Burn, Everest, Performance test, etc. Benchmarks are excellent. One small problem,
Everest shows
+3.3v  =  3.33V
+5v =     5.08v
=12v =  12.48V

BUT,  +5v standby = 3.07v  (??!!)   I'm assuming that's not accurate, Corsair assured me that
software readings are often inaccurate.

I put the SeaSonic 550 watt in an old MSI K8N Neo3-F,
MSI Core Center and Hmonitor show +12v = 11.07 and 11.31

The system works fine, but maybe the PSU caused the problems in the original GA-MA790X-UD4 build.

Hi Johnny

you provided a lot of information, every step of your changes really!

If it's OS problem maybe you can try to solve it by looking at http://support.microsoft.com to find solution or just contact with Microsoft. Or look at http://support.microsoft.com/kb/909279/ if it's problem with time synchronization.
