|Setting up your GeForce for good performance|
We can't promise that you will get the best performance using these settings,but we recommend you to try them. Also remember that other settings in the bios very much affect performance. Especially your SDRAM timings. Overclocking the PCI/AGP bus increases performance, as well as the PCI latency timing will affect performance. Not to forget: when did you optimize (defragment) your hardisk last ? - do it once a week ! Also raid solutions increases overall system performance a lot - systems running stripe0 !
Since a lot of this tips are bios related and it is virtually impossible to cover all motherboards you will have to consult your manual for the motherboard you have. And believe us : you can gain a lot of performance by reading the manual and understanding your bios and how the different settings directly affects performance.
One thing that never can be adjusted is low performance components. The overall performance in your system will never be better than the weakest component - better components allows better bios-settings.Carefully selection of components is of outmost importance for overall performance.Two very important things to consider is high quality SDRAM and the type of chipset the motherboard have. Also the GeForce overclockability varies from vendor to vendor. We skip TV out and other fancy add-ons since we don't need these features anyway.
We recommend that you manually assign a IRQ to the GeForce in the bios and you always leave PCI slot1 empty since these two slots usually share the same IRQ. Read your motherboard manual carefully before you are manually assigning IRQs - and be aware that some motherboards don't have this option.Some motherboard vendors have delivered manuals that is more or less a joke : visit their site and see if they have a better manual available for download. If not - don't hesitate to send their technical department a mail and ask them.
If you got a mainboard with VIA chipset (consult your motherboard manual) be sure you have installed the latest service pack from VIA. The 4in1 driver : which includes AGP controller, IDE controller, IRQ routing and INF. The Smart Function auto detects your windows version and driver requirements, thus installing the appropriate drivers. Visit VIA here be sure you read the Driver Installation Guide at their site before installing the servicepack.

AGP aperture size : This setting specifies the amount of mapped memory (system memory) for graphics data, several mainboard manufacturers recommend a setting of half the installed physical memory.(a setting of 64MB if you have 128MB ram installed). Overclockers know that a aperture size as low as 4MB can be necessarry to reach their desired CPU speed stable. Low aperture size will affect performance : overclocking the AGP bus and the AGP card itself together with a faster CPU can easily make up for this low setting. Anyway you should experiment with the different aperture sizes.Warning: we have discovered that some games/testprograms will NOT run using very low aperture sizes.
AGP data transfer rate :If your mother board supports AGP x4 interface - then enable it since it is backwards compatible anyway. Choosing normal or AGPx1 for a card that supports 2x or 4x in your bios will decrease performance. But again - if you are overclocking you might find it necessary to run with a transfer rate of 1x to stabilize the system - and still get faster performance.
Video memory cache mode: cache technology "uncacheable,speculative write combining" - Enable
Video ram cacheable:Disable
Video bios shadows :Disable
Sideband adress mode: gives a 8 line additional bus to speed up adress and command requests from the AGP master and increasing performance.
Fast write: Enabling this will increase PCI memory write transactions and will increase performance.
Drivers: We have found the fastest and most stable drivers to be the "leaked" 5.30 drivers, this can change with never drivers.
Quadro Hack : just leave it - unless you are a programmer who needs the image accuracy features the hack unveils - you will not get any performance gain in games by doing this hack.
Cooling:We have discovered that the GPU's we have seen is far away from perfectly flat which gives a poor heattransfer. Polishing the GPU and replacing the original heatsink will improve overclockability. Active cooling as water and/or peltier did increase the GPU overclockability a lot on Annihilator Pro. Cooling the ram itself : we tried it both on a Elsa Erazor X² and a Annihilator Pro and discovered that it didn't help at all. We have not tried ramcooling on GeForce2 - but we have discovered that the memorymodules is hotter on the GeForce2 than on GeForce. GeForce2's 0.18 micron die runs a lot cooler than the GeForce.

Tweaking the GeForce for fastest performance:
Several have reported 8-tap anisotropic mipmap method to give better performance : try it !
Vertical synchronisation is disabled in D3D (Disable vertical sync)
Vertical synchronisation is disabled in OpenGl (Always off)
Overclocking the GeForce:
You need to add the coolbits value to the registry the
value is : [HKEY_LOCAL_MACHINE\Software\NVIDIA
Visit the Tweak windows section which will give you a lot of additional tips on how to increase overall system performance.
