The maximum memory supported in a dc7600 is 4 GB.
You can install 4 x 1GB modules or 2 x 2 GB modules in the appropriate slots. Specs do not state you can install 2 x 2GB however, some have reported success doing that.
Fastest speed it will run is at 667MHz if you plan to install PC2-6400 (800 MHz) memory.

Very Interesting that the BIOS sees all the memory!
Here are the specs: I can only list the specs.
Max supported memory is 4 GB. Seeing 3.2 GB out of 4 GB is normal.

Here are the specs on the Intel 945 chipset which is in the dc7600:
Max memory is 4 GB. So I would say the limitation is with the chipset, not the BIOS.
The dc7600 does not support C2D processors even though the chipset supports them. That is a limitation in the dc7600 BIOS.
Hope this helps,

If your OS is 32 bit it will only recognise 3 and a bit Meg of ram no matter how much or in what order, it is a limit of 32bit software.
To see the rest of your ram you'll have to install a 64bit version of windows or a 64bit version of Linux - your full amount of ram will be seen in the OS as well as bios. Hope this answers your question.

The original poster stated running Win x64. It is a limitation of the chipset as I stated. Max = 4 GB
"I have a HP dc 7600 and i install 5GB ram. but my windows 64bit see 3.2GB??"

What operating system are you running?
If XP, click on the PCI device in the device manager. Then click on the details tab. Post the top string of characters you see.
If Vista or W7, go to the same place but now in the Properties drop down list, select the second item (Hardware ID's).
Post the top string of characters you see.
Those will ID the type and model of the PCI device and I can send you the link to the drivers.
