My board is designed with 945GC, and intergrated Atom 330 processer. there are 2 memroy slots. I installed 2 items of 2G ddr2 800 memory, (total 4G)
in the P.O.S.T screen , it can display 4G memory, but in BIOS settings screen , only show 3.3G mem.
and I installed windows server 2008 x64, it shows me total 4G memory in the system interview page.but in task manager, the phy. memory is 3.3G.
I know it is always be that in 32bit os, but never in 64bit os. and atom 330 is support EM64T, it should be find more memory...

Hi there,
Assuming that you have the D945GCLF2 motherboard and it has the same 945GC chipset and the Atom 330 Dual Core Processor, you are quite lucky of getting 3.3GB of memory available in BIOS as well as in the operating system.
This combination of chipset and processor has support for only upto a maximum of 2GB memory support. Link: http://support.intel.com/support/motherboards/desktop/d945gclf2/sb/CS-029532.htm . Hence the answer is simple, this (chipset and cpu) supports only a maximum of 2GB of memory. If you are getting 3.3GB while you are having 4GB installed, if I were you I would not complain.
Cheers

yeah... looks like a bios limitation to me. the chipset itself http://www.intel.com/design/chipsets/express_flyer.htm does support 4gb but i think the platform wasn't designed to work with that much memory.
