Ram!
-
I just took over a old com and the motherboard has 3 ram slots. All 3 slots are filled with 128MB Sdram. Yet when i checked my system in windows, it indicate that i only have 256Mb ram??? Why ah? Can any experts help me? Thought 128mb*3=384MB?
Is it the computer can only display ram value in quantities of 64mb, 128mb, 256mb and 1gb? How much ram is my computer running actually? -
Check the connection of the rams. One of them may be loose. You can try rearranging the order of the rams

Mine displays 768mb ram.

just to make sure, hope you are not using a graphics card that requires 128mb of shared memory (quite uncommon, 64mb more common). windows will only display (via control panel > system or my computer > properties) the amount of RAM made available to the system, excluding any such RAM which may have been allocated to other such shared resources.Originally posted by crescent:I just took over a old com and the motherboard has 3 ram slots.

if i'm not wrong, this conclusion is made based on the assumption (which i've learnt last time in this line) that any faulty RAM in any slots will cause the computer not to boot up at all.
the computer will display the exact kb of RAM you have, and not in multiples of 64Mb. -
Do you have any components that uses dedicated RAM ?

First reason: The maximum RAM could be 256MB. So, even if put 1GB, it will still show 256MB. That is due to the configurations of the motherboard, you can't change that.Originally posted by crescent:I just took over a old com and the motherboard has 3 ram slots.

Second reason: If the video card is integrated together with the motherboard, it will show lesser RAM. That's why 384MB - 128MB = 256MB. -
actually with 3 slots and 256Mb limit is a bit out-of-this-world (64+64+128?), maybe we're talking about a really old skool mobo here.Originally posted by ndmmxiaomayi:First reason: The maximum RAM could be 256MB.

Just a topic sway. Have you all tried to DIY a notebook? PC I know is so common but DIY notebook seem pretty rare. So most ppl in spore is buy ready made notebook and no DIY? Or notebook accessories are not sold publicly?

Notebook accesories hardly sold publicly.Originally posted by sohguanh:Just a topic sway. Have you all tried to DIY a notebook? PC I know is so common but DIY notebook seem pretty rare. So most ppl in spore is buy ready made notebook and no DIY? Or notebook accessories are not sold publicly? -
So those vendors selling notebook having a good time selling cuz they know customers cannot buy accessories go home and DIY. Hmmm.... time to see wat notebook brand good....

Yes. Very profitable. Know know why PCs not as profitable?Originally posted by sohguanh:So those vendors selling notebook having a good time selling cuz they know customers cannot buy accessories go home and DIY. Hmmm.... time to see wat notebook brand good....

same for my laptop.... had 512 ram but displayed only 256+128 = 384... guess the rest went to the integrated graphics card....

i think for notebook, the only thing you can DIY is the hdd. some notebooks also allow self memory upgrades with a special slot underneath the keyboard.

Now that you've mentioned it, it MAY BE possible. If the motherboard is made more than 5 years back for a P2, it may be due to the maximum supported RAM.Originally posted by ndmmxiaomayi:First reason: The maximum RAM could be 256MB.
