| | Video Memory |
 | | There is a limit to how much you can increase the ram on your video card, it may not even let you change it, it does not harm your computer in any way if it lets you change the video card ram like this. | | | eg you have 512 ram on your computer and you are using this no name type video card it will use part of your ram for video rendering so if you have a no name 32mb video card your system will only show up as having 480mbs of ram. | | | Your video card will be set to use all the RAM it has available, so "changing the amount used" would be redundant. |

| | Usually Video RAM is found in 1 or 2 MB sections, and is located on the video adapter in the computer. | | | Video RAM is really a buffer and the computer processor and the display, and is generally called the frame buffer. | | | VRAM or Video Ram means in general any type of RAM used to store and display images. |

| | Which video card? |
| | Typically, video card performance is limited by RAM speed, and an overclock that yields a miserable 10% performance increase for real tasks is considered an excellent one. | | | Any card with a given chipset and a given amount of RAM (or any amount of RAM, if you're not doing something that needs more memory than there is available) and given clock speeds for core and RAM will perform the same as any other. | | | Given two video cards of roughly equal capabilities, identical in all other respects except one of them doesn't exist, the one that does exist is the greater. |

| | Video Memory |
| | That said, video RAM is a special kind of RAM designed with low latencies needed for high speed video environments, so whenever the video card can use its own memory over the system memory, performance benefits. | | | AGP video cards have the added ability to be able to also use the main system memory as part of the overall memory pool, so the video card's own memory is no longer the cut-and-dry limitation it once was. | | | Another issue with regards to memory is the local bus between the video chipset and the video memory. |

| | Shadow Ram Explained |
| | Some programs don't make use of the video ROM, preferring to directly address the card's registers, so you may want to use the extended memory for something else. | | | The drawback is that the RAM set aside for shadowing cannot be used for anything else, and you will lose a corresponding amount of extended memory; this is why there is a shortfall in the memory count when you start your machine if shadowing is enabled. | | | ROMs are used by components that need their own instructions to work properly, such as a video card or caching disk controller; the alternative is loading the instructions from disk every time they are needed. |

| | Video RAM (VRAM) is a term generally used in computers to describe RAM dedicated to the purpose of displaying bitmap graphics in raster graphics hardware. | | | Video RAM is usually physically separate from the main RAM residing in a computer system. | | | This is not always the case as in some systems the VRAM is shared with the system RAM. |

| | DRAM may also be found on lower-priced video graphics controllers and some wave table audio controllers, but it will almost invariably come in a proprietary form that is controller-specific. | | | Because the RAM does not have to send its information to an external SRAM cache, overall system performance is improved considerably. | | | The memory market fluctuates constantly, EDO RAM is now usually more expensive than FPM-DRAM, but less expensive than SDRAM, EDO RAM comes in 72-pin SIMMs and, occasionally on 168-pin DIMMs (dual inline memory modules). |

| | So, depending on your video mode and driver you might be able to store 23.75 megabytes of tiles in your video ram, or you might not. | | | In this example, where we have 23.75 MB left I would figure I could safely use 18 to 20 MB of video memory for textures before I started to see performance problems. | | | If you try to store more textures than your video card can hold then the driver may decide to store some of the textures in main memory and move them to the video card when they are needed. |

| | Extended Data Out (EDO) DRAM |
| | Originally used only for main system memory, EDO DRAM is becoming more popular on video cards because it provides slightly improved performance over standard DRAM at the same cost. | | | EDO is still, however, a low-cost and low-performance solution compared to other types of video memory, and is not used on high-end cards. | | | With EDO DRAM, one read to memory can begin before the last one has completely finished; this yields a raw speed improvement of between 5 and 20 percent, depending on whom you ask. |
