Fast write on or off?

If you're having problems, turn it off. I was having stuttering issues with fast writes on with my GT and disabling it fixed them all.
 
Yeah, I have my x800 clocked pretty decently and fast writes was making my screen show these stupid lines across the screen. Disabling fast writes fixed it. Make sure it's disabled in the bios however.
 
bacon tastes good, pork chops taste good. (name that movie)

Anywho, i leave Fast Writes off most of the time. Vsync off all the time. Fast writes doesn't seem to really do anything, except cause some random bugs. If you run fine with it on, leave it, if you have problem that alleviate when you turn it off, leave it off.
 
Fast writes off for all cards except 9600's. In other words, on in your case.

VSync off for frame rate boosts, unless you get tearing.
 
Fast writes disabled will make the video card not use the video card onboard memory but will instead use the memory from System RAM. So make sure that you have your agp size set correctly in the BIOS. Your agp aperture size should be 1/4 to 1/2 your system RAM size.

So why would I want it on with a 9600XT then?

so i can disable fast write and set apg aperture size to 256 of my total 1024 of ram? will i see any performance boost by doing this?

let me know what you see, I forget what I have it set at?

lol... How on Earth did you comes to this conclusion? This thread is n00bie central..


From Adrian Rojak's site www.rojakpot.com (who by the way is THE authority on bios settings):

This BIOS feature controls the chipset's AGP Fast Write capability. Fast Write is a feature which accelerates memory write transactions from the chipset to the AGP device.

Normally, any data meant for the AGP device must be written to the main memory for the AGP device to read. Fast Write allows the AGP device to bypass the main memory and directly access the data. To do so, the AGP device will act as a PCI device whenever the chipset attempts to write to it. This allows the data to be directly written to the AGP device (like other PCI devices), instead of being written to the main memory first.

As you can see, bypassing the main memory saves time and improves the AGP read performance. However, AGP writes (to the chipset) will not benefit from Fast Writes as it will follow normal AGP protocol and write to main memory.

In addition, while PCI signals are used for Fast Write transactions, the behaviour of those PCI signals has been modified and do not follow PCI specifications. Therefore, this feature may cause problems with some PCI cards.

Therefore, it is recommended that you enable AGP Fast Write for better AGP read performance but disable it if any of your PCI cards start acting funny.

Please note that for AGP Fast Write to work, both motherboard chipset and graphics card must support the Fast Write protocol and the data transfer rate must be at AGP2X or faster.

so........if i enable it, what should my agp aperture size be set as?
 
how about write combing? So with the aperture size it says 64mb or 128mb. What would be the best for a 9600XT?
