A7N8X can't keep time

[acemcmac]

Time on this computer runs so fast, I recently installed nikki time and it's reporting that every 6 hours, the computer clock is ahead 30 seconds... thats 2 minutes a day and up to 6-8 minutes off in between windows time snycs.

Now that nikki time is forcing more frequent time updates, this isnt as big of an issue, but I was wondering if you guys knew of anything that could be causing it?

dead mobo battery? firmware?

Don't know what it is ... but, my A7N8X-E DX gains about 5 mins every 10 days. Not really a big deal for me. Likely a design flaw. I thought it might be because of OC'g, but it gains when not OC'd.

CMOS Battery.

The only problem I have with that is that this machine never turns off... its my 2003 server... would that still be the battery?

Yeah. I had the same problem with an Abit NF7-S v2.0. The Windows clock would constantly run faster than normal. I was also continually syncing with Internet time until I figured out the problem.

I'll go with CMOS battery too. Just like a watch, when the battery gets low, it gets inaccurate. Seems like a pretty good guess.

Wouldn't logic suggest that when the battery gets low, your watch, or clock, would lose time until it finally stops ?? These boards are gaining time. When I check my voltages via ASUS probe .. my 12v is 12.4v and my 5v is 5.3v. I don't know if the clock is controlled by 12v. or 5v. or just off the CMOS battery; but if it's from one of the voltage buses it therefore is getting the extra boost from the slightly higher bus voltages.

There's a simple way to determine if it's the CMOS battery. Goto the BIOS and change a setting. Save the BIOS, turn off the computer for 10 minutes, and turn it back on and check to see if the setting is still saved in the BIOS. If not, replace the battery.

I'll try these during my next maintanance period. Thanks guys.

It may still save the settings, but the clock will gain/lose time because the voltage is out of spec.

Yes, logic would suggest that... But it depends on the circuitry. Some clocks might lose time under low voltage, others may gain time.

Edit: It might not be the battery at all, just something that came to mind. To check it, if you have a multimeter, just test the voltage. Should be a little higher than 3 V. If it's any lower than 3.0 (i.e. 2.9), replace it.

Sorry, I thought the problem was it wasn't keeping time....

It should be stated that the system clock operates independently of the CMOS battery. While powered on the system clock is run off of mobo power. The battery is just to keep the bios settings saved and the system clock active when the computer is shut off. So either it's your mobo or you have a program or service that changes your time.
