Its simple you must have the system in OS install Mode, for some legacy OSs they can only install with 256 Max RAM.

The setting is in the BIOS or setup. its easy to find and its called OS Install Mode

Windows xp will usually only see 3.5 gbs of ram even in your motherboard can support more. WIndowns vista does recognize more RAM or i also believe windows xp 64bit recognizes more ram. Nothing wrong with ram or your computer its just your operating system.

RAM Only 3Gb

Err... Do you mean it has more than 3 GB and it sees only 3 GB or it has only 3 GB?
For first one: You are probably using a 32 bit operating system. For example, Windows XP 32 bit sees only 3 GB of RAM. Fix it by installing other operating system(or simply a 64 bit version). Also, linux is known to work with more than 3 GB of RAM even on 32 bit system.
Second one:
You could buy some aditional RAM, but first check which RAM type are you using(DDR, DDR2 or DDR3). Also, you should check if there are any free slots left, and does motherboard support more RAM.

I forget bios password for HP DL160 G6 server, how do i reset the password ?

  1. Shutdown your server.
  2. Go inside the server, and remove the CMOS battery. It should look like this.


3. Be sure to power down your server before taking it out. Be aware that once you take this out the system will forget a lot of it's time settings. This is the battery that keeps the computer's memory of time, date, and BIOS password when it's shutdown.

Memory issues with thecus n8800pro

This is normal with a Windows 32 bit OS and the 4gb limit. 3.5 is about average, if that. Not sure about Linux?

You may try checking BIOS for RAM max settings.

Ram cards


Make sure that when you populate the memory slots that you are using like memory cards per memory bank set. Example: A1 and A2 consist of one blue and one beige slot. Use a 2GB card in one and a 2GB card in the next one. Starting with A1, use your 2GB memory cards first and then the 1GB cards. Once complete, reboot your system and enter into the BIOS to verify the total 12GB are being "seen" by the system.

Also, consider your os. If you are running Windows Vista 64 bit, Windows 7... they will only see 8GB max. OS like Windows server xxxx will be able to see all memory avaliable to the unit.

Good Luck

Do this model supporsts win xp service pack 2


This unit has a Pentium 4 2GHz single core processor, and does support Windows XP SP2.

The standard memory installed on this unit was 256KB RAM, in order to run XP efficently you will need to upgrade the RAM. I suggest upgrading RAM to the maximum amount allowed of 2 GB RAM.

To upgrade the RAM to 2 GB you will need 2 modules of 1GB PC2100 184 pin DIMM ECC each.

Windows doesn't see my 6 GB of RAM but BIOS does

You have the same machine as i. To the best of my knowledge it does not support 2 gig sticks. Thats why the say it only supports 4 gig of ram. I hope that is correct still. I also do not have a12 Bios so it could have changed.
