I bought new system with Intel Core 2 Duo 2.00 Ghz 64bit and 3 GB Ram.
I installed Windows 7 Ultimate 64bit. After installing It showing 2.75 GB usable instead of 3 GB then what can i do?, If I upgrade 3 GB to 4 GB then what it shows?
Can you explain this?

Hi, and welcome to the forum. 
Probably because the other 0.25GB RAM is being utilized for integrated graphics. If you install another 1GB RAM, your system will likely show 3.75GB out of 4GB as usable.
If you have a dedicated graphics card installed, you may be able to go into BIOS and disable the onboard graphics.

Hi Jim,
Thanks for your reply and excellent explanation.
I have Nvidia Geforce GT 210 graphics card installed.
Can you give settings of bios for disable onboard graphics.
I have Phoenix Award Bios latest (It shows updated in 9th June, 2013 don't know exactly ). I disabled onboard graphics (may not disabled perfectly) but you said 0.25 GB is reserve for integrated graphics, then how can i disable it?

You may not be able to disable onboard graphics. Phoenix Award BIOS has many different versions, and different motherboards will also have different chip sets installed. From my experience, there are far more BIOSs that do not have this option than those that do.
What are you worried about anyway? 2.75GB RAM should be more than adequate to run Windows 7 okay, especially with a dedicated graphic card installed as well. Is your machine running slow and unresponsive?

No Jim... I want to use completely 3 GB Ram. But there is no problem with my PC, it runs fast and smooth.
Phoenix Award Bios Version is 6.00 pg. Motherboard is 945.
Thanks for your support and time..
Okay, but your mobo model "945" doesn't make much sense to me. Sounds like it might be a Gigabyte mobo but there is a range of '945' models, we would need the exact model number.
Try this:
Boot into BIOS and look for "Advanced Chipset Features".
You should see a setting "Video RAM Cacheable" under "Advanced Chipset Features", set that to "Disabled".
Then exit BIOS saving new settings (usually F10).
Here is a full PDF guidelines to your BIOS: http://www.answersthatwork.com/Download_Area/ATW_Library/Hardware_Maint/HW___6-Award_6.00PG_BIOS_setup_guidelines.pdf
Bear in mind that settings might be not all be the same for all chipsets.

Thanks Jim for your great support.
I don't know the exact model number but I tell you latter after looking into my motherboard.
Thanks you

Hi Jim....
My motherboard is 945GV-775.
Thank you
Krunal..
I can't locate the full specs for that particular motherboard and chipset anywhere. It must be pretty old (superseded) and perhaps unique to India.
Did you try the following from an earlier reply:

I tried this steps but not working, still showing 2.75 GB. "Video Bios Cacheable" = Disable.
Krunal...
Okay, this may seem a rather silly question but you never know... is your monitor definitely connected via the graphic card?
Hi Jim,
Yes my LG LED E1942 connected via Graphics card (VGA Port).
Krunal
Okay, well standard VGA uses 256KB RAM which is your missing 0.25GB.
I really don't know where we can take it from here Krunal. I'll refer this to Dave who is a lot smarter than myself. Perhaps he can come up with a solution.
Stand by!
Cheers... Jim
