Motherboard can't keep time

[cnorton]

I have an Asus A7N266-VM mb that is always running faster than the actual time. Now if it was running slow I would try changing the battery but I don't have a clue what would fix this problem. I have been using some software to keep it in check but there has to be a way to fix it.

Is it running too fast when Off, or when On? The real time clock and battery are only relevant while the thing is Off; when it's on and running, the clock is maintained in software.

It is running fast when it is turned on. I reset it in the bios and I when I check the time again later that day it will be gaining time again. Same thing when resetting it in windows.

They don't mention this in the BIOS updates, but it might be worth a try. Going off of Peter's statement, it may not solve anything, but it's worth a shot.

does the OS write to the RTC on power down?
or is it only RTC>OS on boot?
