How do you increase the video memory dedicated for a game from 64mb to 128 mb?
you can't or you can get more ram but it only increases shared memory video!
Is dedicated video memory still better than a significantly bigger shared video memory Like the Acer AS5530-5041 with 256 dedicated AND 640 shared versus the Acer AS7520-5181 with 1792 shared only?
Yes, dedicated memory is always better then shared (or integrated) edit answer after editing the question: but what is the shared memory option is much bigger than the dedicated option? (See edited question)
What is dedicated video memory card?
One that is used only for the video, rather than a chunk of the main memory which is shared between various tasks.
What is video memory on your computer?
Video memory is the RAM in your machine that is used exclusively for your graphics hardware. This can be both the RAM chips built into the graphics chipset its self, or it can be the RAM that is optionally "carved out" from the system memory. The latter is called "shared video memory" although it isn't really sharing as the graphics hardware uses it exclusively.
Is a small dedicated video memory 256 plus 640 shared better than large shared 1792 only?
yes as long is dedicated, is better
Compare distributed shared memory and centralized shared memory?
yes
Can you upgrade video memory on a Acer Aspire 5100 laptop?
That depends on what kind of video card you have. If you have an integrated video card (most likely) you may be able to allocate some more shared memory to the video by simply adjusting a setting in the BIOS. You can find out how to do that in the system manual. However, many BIOS config program will not allow you to allocate more than a certain percentage of system memory, so increasing your total system memory might allow you to set a higher percentage of shared memory to the video adapter. However, if you have a dedicated video card, it would have it's own memory built into it, and therefore you wouldn't be able to increase it, short of replacing that video adapter entirely with one that has more memory already on it. Check your system specs with the manufacture and see which you have, and proceed from there.
How can you alter your Shared System Memory for your Graphics Card without entering BIOS?
Some motherboards actually used a jumper to set this... but this is extremely rare. I'm afraid on most boards your only way to adjust this is through system BIOS. If your machine has an available AGP or even PCI slot, you would do very well to put in a video card & just disable your onboard video.
Does the 512KB Mac Video RAM only upgrade my video memory, not my system memory?
That's correct, it will upgrade your video memory and not your system memory.
How do you get video memory on a computer?
how can i get the video memory address in computer?.
What is centralized shared memory architecture?
MIMD(Multiple Instruction streams, Multiple Data streams) multiprocessors fall into two classes Centralized Shared memory and distributed shared memory Centralized Shared Memory Architecture has at most a few dozen microprocessors chips, that shares a single centralized memory. They have large caches, single memory, with multiple banks. The single memory has a symmetric relation to all the processors and uniform access time from any processor.
What are disadvantages of shared memory?
Interesting question. Most agree that shared memory should be minimized and that you should use IPC rather than shared memory if at all possible. Object Oriented programming suggests that an "Object" have it's own methods and that should be the only way that the data object should be modified. Shared memory tends to bypass that construct. In the current programming environment, shared memory is no longer recommended.
