View Full Version : bios update (p4c800)

19-04-2004, 10:58 PM
I have an asus p4c800 deluxe mother board and the bios version is 1010. I am missed out on 4 bios updates which are (1011, 1014, 1015, 1016). Should I update from 1011 through to 1016, or can I update straight from 1016?

When I went to update for 1016, it said that update was succesful but when I checked the bios version, it still remained the same with the exact same date.

Is anyone able to help me?

BIOS updates are not like Windows Updates.

Only apply them if there is a problem identified with your system that requires the update.

If an update goes wrong (and believe me, they do) then your entire motherboard can be rendered permanently useless.

Oherwise there is no need to apply them sequentially. You should apply the one that specifically fixes the problem that you have with hardware or software, as identified by the motherboard maker. Usually the latest one.

Thank you Godfather,

My cpu seem running little hotter than normal ( from 24-42 degrees) and

also it give 3 Bios beeps when the computer power up.(in my Subs motherboard PC Deluxe user guide said 2 beeps Parity Error, 3 beeps Main Memory Read/Write Test error)

So I though Bios update may will fix the problem.

Thanks again.

There is no way a BIOS update could affect the temperature of the CPU.

And you need to run a Memory Test program (http://www.memtest86.com/) to test the memory. Its unlikely to be fixable with a BIOS upgrade unless some mention is made in the release notes.

Before you even think about flashing the BIOS, read the release notes for the BIOS upgrade. If they address real problems that you have, then try it. If not, there is simply no need to do it.

If its not broken, don't fix it.
Or, keep fixing it until it is broken.
2 choices...

Hi Godfather.

It sounds very technical to determine the fault which part cause the beeps ( some time 2 beeps but other 3 beeps). I think it is out of my reach of knowledge.

Apart those beeps when it power up, the computer work fine. I wonder If I don't find what is wrong with which part of the hardware it may cause feather damage to the computer?

Should I leave the Bios beeps alone or should I do some more search ?

Thank you.

After doing the BIOS update did you reset to default settings in the BIOS?

i.e. Load optimized settings

Also it pays, if your BIOS has the option, to reset the PNP data.

If the beeps where present before the BIOS update then it is likely you have faulty RAM and the sonner you look into it the better!

Hi Ugh 1

No, I didn't reset the Bios to default setting.

All the setting as normal after Bios update so I just leave it as it is.

The next step I think I will have the Rams check it out.

Thank you for the info.
