776mb now its 1gig????

I have 1gig ram. Two stick of 512mb ram. My Onboard ati radeon x1250 graphic use 256mb ram from the system ram.... so total shows 767mb when I right click my computer.

Anyhow.... I open up the case and plug out one of the rams stick and plug back in.

Now Power Up the computer... I notice the performance improvement! it feel so much smoother and faster! then I right click my computer to see if the ram reads correctly in case the ram I plug in was loose.... this is when I found out that it reads 1gig ram now!!!! how???? so is this mean my onboard graphic stop taking the 256mb from it? if so.... what if I want the graphic to take back the 256mb from it? how do I do it? and is it normal to replug/plug ram and it disable the graphic from taking the memoryfrom the system ram?

edit: title is misleading. it is supose to be "767mb now its 1gig?" not 776mb

Your video card wasn't taking any memory to begin with. When you reseated the dimm it was then down fully in the slot and could be fully detected. Apparently Windows was only partially reading the dimm only making partial contact when first put in the slot.

On older boards the option was seen in the bios for seeing part of the system memory shared with the video card to assist in processing textures. You increased the typical default 64mb aperature to match the size of the card. But it isn't normal to plug and replug memory in since that was simply from having the dimm fully seated down.

Er....I don't think so. A DIMM that is not seated properly wont be partially detected. It will either not be detected at all or it will fail the POST test.

Did you plug the RAM back into the same slot? And is your x1250 integrated?

Onboard is used there. But even that shouldn't be grabbing 256mb off of the top. If all contacts with one or two just barely touching and seeing a small fraction of current then the dimm would have been underpowered and only partitially detected being in a reduced capacity.

Once reseated the dimm then saw the normal voltage levels and was then accurately read by Windows. If the onboard was taking away from the available ram you would be seeing something like 768mb for a total.

pc eye have a point. it never show 768mb for me but only 767mb. so its just the ram is not seating properly?

but.... as I study and ask around many says reason why I have 767mb when i supose to have 1gig is due to the onboard graphic takes 256mb from the systam ram.... but.... it should show 768mb... but why would it shopw 767mb? this is when pc eye theory have a point.

but but.... i thought i was sure that my computer have an onboard graphic that takes 256mb from the system ram? it is an onboard integrant shared ati radeon x1250.

note: i plug/replug the ram at the exact same slot as before.

With one 512 knocked out you wouldn't even be seeing over 512 to begin with yet you were seeing 767mb. If you subtract 512 from 1024 you still end up with 512mb. Somehow you were still seeing limited activity from the dimm before reseating it likely from the poor contact from being slightly raised in the slot.

You would think that with now seeing the full 1gb recognised that 768mb would be the end result due to 256mb being shared with the onboard video. That is the common thought like that seen with...

Why does your PCs RAM appear as 192mb when you bought it with 256mb?

When there is a difference like that in the RAM count, it usually means that you have a "shared" ram with a 64MB on-board video card. That's one of the reasons why it's good to load the computer with as much RAM as you can afford; it increases the number of applications that you can run concurrently without being affected by the hardware needs.

Shared memory doesn't quite mean any total amount taken away but shared. Windows is reporting 1gb while not indicating how much of that is being shared and not available as ram.

hmmm.... not quite understand yet. english is not my first language. so.... umm.....

1: why is it reads 767mb at the first place?

2: when I replug/plug.. why it reads 1gig now?

it might have been plugged in badly, now it is better so the computer will work faster.

Before you reseated the dimm Windows reported 767mb installed. Later after reseating the dimm and then seeing a fully functioning dimm Windows then reported the 1gb total. With the dimm having been raised up in the slot it wasn't seeing the proper contact but enough to allow some voltage to go through in order for Windows to see something there.

It's best described like a volume control knob where you can turn the voltage down not the volume. The contacts on the dimm were still touching the contacts in the slot but not enough to allow the correct voltage for it to work properly.

ahh ok so the problem is just the dimm is not seated properly from the beginning? what about the story about the integrant graphic takes 256mb from the system ram? it never did? and not supose to?

I didnt care when I pull it out... so I didnt notice if its loose or not.... kindda regret..... should of check before pulling out.
