I have an acer aspire 5100 I had 1G of ram in it however it showed in the properties as 768M I just bought 4G they cam in 2 2g sticks they are so-dimms 533 I installed them and now the properties age shows 2.62G. is this right?
if you are using onboard video (you don't have a video card installed properly) then you computer shares the ram with your video and the ram that is shared will not show in your computer b/c that has already been dedicated to your video processing.
The 2.62 GB is going be because Windows (in 32-bit) won't see more than 3 GB of RAM. Couple that with integrated video (like xtreampb said), and you come out with 2.62 GB of system RAM.
4gb of ram = 4,000,000,000 bytes from an advertising standpoint but realisticly a computer calculates 1 gb as 1024 x 1024 x 1024 so 4gb of advertised ram is actually 3. something actual gbs which is how windows or the system sees it. Then add to that a 32 bit processor can only address 2^32 of ram so take 2^32 and subtract and ram used by your graphics card or system graphics and anything else that reserves ram and then you can see what is actually available for windows to use.
I hope I covered everything lol
PS Thats why the 160 gb hard drive that you buy only shows up as like 149 actual gbs. or 160,000,000,000/((1024 x 1024 x 1024) x 160) and I always hated math. My stupid calculator wont display a number that big.
Actually 4GB is 4GB. My wife has 4GB in Windows XP 32 bit and it displays as 3326MB. 4 GB is indeed 2 x 2048, I know this as I'm running 8GB on Vista 64 bit and it displays correctly. The only reason I can think of for his to only 2620MB is because he's using on-board graphics and my wife is using an XFX NVIDIA GeForce 8600GT 512MB card.
It just seems that way. But the marketing divisions at the various hard drive companies count a gigabyte as 1 billion bytes, that is, 1,000,000,000 bytes, when a computer will count it as 1,073,741,824 bytes, or 2 to the 30th.
