    Not so helpful. found out xeon 5600 chipset accepts only 1333 ECC RAM, which I was not using.

If you know for sure that the board is functional ...take it one by one ...
first be sure that the CMOS jumpers are in the right position ...and they are not shorted..
than check the Ram memory be in place ..and well inserted..even change them with another one if you have in handy ..
Check the power supply to be all in place ....(if you use a 20 pin on a 24 plug be aligned in the right ) ...
the last but not least ..check the CPU fan be well powered and functional ...This one should spin even if the board do not boot....remove it ..and verify the CPU to be well inserted the proper position ..and the fan on it to be perfect fixed ...cause if not ..the unit will not boot..
If all that are checked..and still nothing ..try a different power supply ..cause there is nothing else to be wrong ..and it might be something from the board..or one of those I mentioned..

    try to see other makes..cause some will accept inferior frequencies if they are not the maximum allowed size in one slot..
    for example I use in a ddr 2 800 a ddr2 400 and one on 533 with no sweat ..and they being put on auto ..the frequency read is 400 always will take a inferior one ..but not a superior..
    even so ..I did used with success some 800 frequency on a computer that was made for 533 max...but it only read half of the value ..and after a while kept giving me a hard time on boot..
    In theory can use inferior frequency with no issue ..if you have some ddr3 on smaller will work ..

Hello, I just replaced my motherboard for my acer aspire 7741z-4433, The battery went from red(charge) to blue(charged). Now the computer won't turn on. I tried to reset the cmos. I'm out of ideas. Ev

Double check and compare with the original board. Are there any jumpers that you missed? If any of the chips are removable, try using the chips from the old board, especially a bios chip - if it's removable. Disconnect peripherals one at a time, and try to boot. For example, unplug the cables going to the cd/dvd drive and try to boot, if it boots, then that might help you narrow it down to the peripheral that you disconnected. check the output on your power cable input with a volt meter. compare the voltage output of what is listed on the power brick. If you swapped the processor, try taking it back out and reseating it. Check for bent prongs on the processor. If you reset the CMOS, are you trying to boot from a disc so that BIOS can be reloaded? You might try just unplugging all cables to the board, then plugging them back in - maybe there is one that is just not getting a good connection. I'd be curious to know why your were replacing the board to begin with.

Won't Power On

  1. Remove all external peripherals/devices/equipment connected.
  2. Keep the power button pressed for at least 10 secs to let the system discharge any static electrcity.
  3. Check for any beep sound, if the fan is working or not (In case the fan is running, could be a dust problem.
  4. Try replacing or interchanging the RAM.

Let me know for any changes occurring so I could help more on this. If no changes occur then call for a technician.

Forgot bios password

Shut off the power supply or unplug the Server.
Press the start button.
Now remove the battery for at least two minutes.
Replace the battery.
Re-energize the power supply.
Turn the server on and enter the BIOS.
It will have forgotten all settings,
and will be at the default settings with the password erased.

PC locks up at Supermicro splash screen during warm boot

Check for a post error in the bottom right of the display. It will be 2 letters or numbers. You can refer to the manual to see what the exact issue is:
Super Micro Computer Inc Products Motherboards Core 2 Boards C2SBX

However, the most likely culprit is RAM. I would try booting with 1 stick (and try all 4 dim slots) to see isolate the issue.

Menus Locked in BIOS of 5014c-mt super server. Cant navigate to any sub menus... How did this happen????

Hello here is the homepage:

Try to reset the bios, by removing the cmos battery.
And insert it again.
This will clear the bios, to factory settings.
But you have to setup the bios again: date, clock, boot settings etc.
When you get it running again, try upgrading the drivers and bios to the latest version.

Hope this will help you.

32-bit is also a term given to a generation of computers in which 32-bit processors were the norm.

64-bit CPUs have existed in supercomputers since the 1960s and in RISC-based workstations and servers since the early 1990s. .

Need help on SuperMicro SuperServer 7043M-6!!

ok, all you have to do is reset CMOS. the same thing happened to me once I tried to install windows on my supermicro board. What you have to do is load the bootable CD that came with the board and follow the instructions in your book.

What happens is that windows does not have the drivers for the supermicro RAID and SATA components. The board will recognize these on it's own until you go to install windows improperly. Windows does not have the drivers for those, realizes it, and says "Windows has stopped to prevent damage" but it does it anyway. Just clear CMOS, read the book with the board on how to install an OS, and try again.

Clearing CMOS: This can be done by taking out the 3.5v watch battery you see on the board for about 5 minutes. Another and riskier way is to clear CMOS by shorting the pads. On a diagram of your board, you should see CMOS Clear. Find those two pads on you board in that general area from the diagram. You'll know you've found it because the board has CMOS Clear printed near them. Just touch them with a screwdriver for 5-10 seconds. CMOS should be clear and ready to start new.

WARNING! Be careful when clearing CMOS with the pads, if you stick the screwdriver in the wrong place, you could damage your board. Be sure to unplug your power supply before working on your machine (I'm sure you know this.) and be sure to get the correct drivers for windows this time! Oh, and rechange any settings you changed in CMOS since it has been reset to the factory defaults.
