I just removed my 256MB RAM Memory and installed a 512MB one, why does it say 448MB RAM when I right click and take properties on "My Computer", it said 192 when I had the 256 installed. If I install both the 512 and the 256 will I get 768MB of RAM? If I want to install a graphic card, do I just have to pop it in and it's ready to go?
Because 64mb is being used by your motherboard for onboard video and yes if you install both the 512 and the 256 you will get 768MB of RAM minus 64mb for the video. If you install a graphic card you have to disable the onboard video and install the drivers for the new video card. Disable-Onboard Video Guide
Oh, I see. Should I install that 256MB one? and I don't have a CD for the graphic card, I got it from my brothers friend. He gave me a whole comp without a harddrive, I just recently took the 512MB RAM memory out of it and placed it in my comp.
Most likely, you have an integrated graphics card that shares 64MB of the main RAM. Hence, 512 - 64 = 448. You should be able to install both the 256 and 512, which would give you 512 + 256 - 64 = 704MB. Regarding the graphics card, unless your computer is really old, it should have either a AGP or PCI-Express slot. Find out which one it has, and buy a video card that works for that slot.
I don't think I will install the graphics card as it's too much trouble and my computer is around 6 years old.
Is th RAM the same type? Find out the PC type of the ram (e.g., PC2700), the RAM speed (e.g., 333 Mhz) Look at both the sticks and post the details on the labels. You can get the video drivers on the net what type of video card is it?
I just installed both of the rams, and they seem compatible. 512MB Ram Memory: 512MB UNB PC2100 CL2.5, The model is Apacer. 256MB Ram Memory: DDR 256MB PC2100 orig, 256MB PC2100 DDR266, DDR266(2.5) 256MX8, The model is A Data - Memory Expert I'm not sure, but I guess they are the same type because they are both PC2100 and they are both 2.5Mhz(?) It said different things on the 256MB one, so I wrote everything.
Another question.. Will this "PC133 512MB 10276 081133" work with "512MB UNB PC2100 CL2.5, The model is Apacer." The first is a another RAM Memory I got from my brothers friend, but I don't know if it will work because it is PC133 and that is all it says on the label.
It really doesn't matter what brand RAM as long it fits and is the right pin type. The PC# appears to be different so I don't think it will work(Not sure about this). You can mix RAM, but it is most recommended to get both of the same size. If you buy the same RAM sticks that are compatable/say they are dual channel compatable, you can use Dual channel, but I really don't know what that does or what the advantages are. Though I have been hearing Crucial is a good brand. I think I'm using a Samsung 512 MB with a Patriot 2 GB both at 533 MHZ.
Quick answer no it use's a different type slot. @TheWingless It does matter if you put in 1GB PC3200 DDR400 and a 256MB PC2100 DDR266 you have to put he PC2100 DDR266 in the first RAM slot or the PC would not use it and the PC3200 DDR400 will run at DDR266 speeds so you would better off only using the DRR400 at full speed. The Brand is not importent but the Type and Speed is.
Oh really? I never really knew that, but I'll make sure to be careful of that. I did a lot of research before buying my RAM though so I didn't run into any trouble. Probably just best to buy them in pairs or memorize the last RAM stick you bought so you can match it up. Both of mine are the same speeds so it's perfectly fine over here. I'll probably buy a another 2 GB if I ever need it to replace the last 512 MB I have. BTW, what is the PC# for...? Is it speed, or does it even affect is physically?
