Whats the difference between RAM and Video Card RAM?

I just started playing World of Warcraft and when I installed the game, it showed a message that said the minimum requirement for RAM wasn't met, but the game runs fine usually. I have every setting on the lowest possible and the game usually runs between 15 fps and 45 fps just depending on what area I'm in (ex. a city full of people compared to an empty room). I was just curious if increasing the amount of RAM in my computer would improve performance or if I would have to buy a video card with more RAM on it (my current one is a GeForce FX5500 with 256mb of RAM I think). Also, would I have to switch from my current video card back to the motherboard one if I just increase the computer's RAM? Sorry if this doesn't make much sense... but thanks in advance for any help you can give!|||The message you received means that you do not have sufficient system memory, your video card should work fine as it meets the minimum requirements for WoW. You need to check your system specifications sheet for your motherboard to determine what type, speed, and maximum capacity of memory it supports. It wouldn't hurt to know how much you currently have installed and what speed it is, then add more memory to reach a minimum total of 1gig, but 2gig would be better provided your motherboard supports that much. What you are looking for on the spec sheet is does your motherboard use SDRAM, DDR, DDR2, speeds like PC2100, PC2700, PC3200, PC2-6400, etc. It might list speeds like 266mhz, 333mhz, or 400mhz also, these are represented by the first three listings I showed of PC#### above respectively.



Video cards with dedicated memory do not increase the normal system resource memory which you are failing to meet, that is entirely different memory for a specific purpose.|||Your video card is sufficient for this game.



There's two types of ram (in this senario). There is System memory, and Video memory.



You have enough video memory, no questions asked.



You DO however need some more system memory, this is cheap you can buy some on ebay.com or your local computer store.|||You have RAM chips on your motherboard, some mother boards have two slots some have four.



RAM comes in 64MB (very old), 128MB (also very old),

256, 512 and 1GB. Doubles each time.



Video Cards need memory also and on most computers the Video cards uses (steals) some RAM from the Mother board.



That is why when you open up System in Control Panel and the RAM number is something less that what you think you have.



High End Video Cards have their own RAM on board, usually around 128MB or 256MB. There is a story I read that there will be a Video Card out soon with it's own 1GB of RAM...WoW!



Hope this helps clear the cobwebs.



Bill|||cuoc do`j that la vovi faj? hok cac ban|||Well, I have to add something. having 256VRAM doesn't mean it is enough. why ? Basically, VRAM is a RAM that is specially used to processing video data, while the normal RAM will process any data. however, 1 thing that is not yet mentioned here is the VGA processing Power.



If, the processing power of the VGA is slow, the data will end up using VRAM more that it was necessary in terms of time. so for example (I'm using ATI radeon as an example because I only use it ^^)



you have a 9800XT with 256 Mb RAM (9800 is a top model around year 2000)

You have a X1900 with 256Mb RAM (top model around 2006)



it doesn't mean the same. first, see the RAM type. one is using 256Mb DDR2 RAM and the other is 256 Mb DDR3 RAM. so even though the size of RAM is the same, the processing power is not. for your case, I would recommend you to buy a new VGA card. you will see the difference. but remember that in online game, the connection speed also matter....
