Graphic Win Size on BIOS (ECS K7S5A Pro & Ti4200 64MB)
I was just checking through the unnoficial K7S5A Motherboard Guide v1.2f,
and it says the following with regards to the *Graphic Win Size* setting: Graphic Win Size From http://www.rojakpot.com: This BIOS feature allows you to select the size of the AGP aperture. The aperture is a portion of the PCI memory address range that is to be dedicated for use as AGP memory address space. Host cycles that hit the aperture range are forwarded to the AGP bus without need for translation. The aperture size also determines the maximum amount of system RAM that can be allocated to the AGP graphics card for texture storage. The AGP aperture size should be calculated using this formula : maximum usable AGP memory size x 2 plus 12MB. The actual usable AGP memory space is less than half the AGP aperture size set in the BIOS. This is because the AGP controller needs a write combined memory area equal in size to the actual AGP memory area (uncached) plus an additional 12MB for virtual addressing. Therefore, it isn't simply a matter of determining how much AGP memory space you need. You also need to calculate the final aperture size by doubling the amount of AGP memory space desired and adding 12MB to the total. Note: Graphic Win Size is the equivalent of AGP Aperture Size. Well my system is as follows: - Tsunami Sagittarius ATX window case & 350W PSU - ECS K7S5A Pro mainboard - AMD Athlon 2600XP CPU (266 FSB version) - ThermalTake Volcano 11 Xaser Edition CPU heatsink & fan - Western Digital Caviar ATA100 80Gb 7200rpm 8MB Cache hard drive - 1 x 256MB PC133 Kingston SD-RAM - Inno3D GeForce4 Ti4200 64MB graphics card - Sony 1.44MB Floppy Drive - LG DVD-ROM GDR-8161B 16x48 - LG CD-RW W8520B 52x24x52 - Windows XP Pro So what level should I set the *Graphic Win Size* at to benefit my system most while gaming? (I know... long explanation for a short question) Thanks in advance. |

All these so called formulae are bogus.Set it to 64 meg unless you run some graphics demo that requires it higher. http://www.tweak3d.net/articles/aperture-size/ HTH -- Free Windows/PC help, http://www.geocities.com/sheppola/trouble.html It's a G not a J in gmx for email Free songs download, http://www.soundclick.com/bands/8/nomessiahsmusic.htm |

Actually if you read the article that Shep linked to, they recommend that you set it to a minimum of 128MB. They also recommend to use 256MB if it doesn't cause a problem and you have ample Physical ram on your machine. "Performance is nearly identical from 16 to 256 MB, with minor dips at 64 MB AAS and problems with 256 MB on the GeForce3 Ti500 card. With new games coming out all the time that push our PCs to the limit, it might be a good idea to try and run a higher AGP aperture size, to be sure you've allocated enough memory for the video card. For this reason, we suggest at least a 128 MB AAS unless system memory is very low, or problems are experienced. Ideally, you'd want to run a 256 MB AAS, as it would result in the best video performance and compatibility. As our tests showed though, 256 MB AAS does not work on all PCs and configurations, so it must be tested. You should run an AAS of 256 MB on your system if you do not experience problems and you have the memory to spare (or you do not notice problems with applications hogging your memory). Remember that even if you have a 256 MB aperture size set, it is highly unlikely that you'll use nearly 256 MB of memory at a time." |
