So I have a 6800 w/128mb mem and a sys with 1gb ram.

I have agp fastwrites enables in bios and I have an apeture size of 256mb does this seems right?

I am curious as to what the apeture size should be and also whether fastwrites truly helps or not.

the best settings IMO

A Size: 64Mb

FastWrites: Disabled

explanation:

A Size: you may or may NOT know that A Size is how much memory is set aside in RAM to help the v card. so it is useful. however, the difference between 64Mb and 256Mb is negligible so 64Mb is optimum here saving necessary room.

Fastwrites: basically this is meant to speed up AGP speed. However, test have shows that it has ZERO to LITTLE effect. furthermore, it is prone to prevailing in crashes (especially with OCed cards).

In summary, these are just two silly options which are totally worthless. i say, go along with my recommendations - benchmark, and then turn fastwrites ON and A Size to 256Mb and see the difference - it will be nothing to little (IF NOT LESS /ohmy.gif' border='0' style='vertical-align:middle' alt='ohmy.gif' />

you can also try 128mb. i have a 128 mb card and it did performe much better when i set it to 128. just try and see what happens. also, try to leave on fastwrite unless you get problems.

OK so go as low as possible with apeture size I guess and then if I am not crashing (which I am not) then I should leave fast writes on for whatever speed boost may be there.

does this sound right?

yes. start the agp apeture at 64mb and see if there is a difference at 128 or if you mobo does have the setting 256. good luck. if you can, let me know at what settings were best. /smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' />

If you have a 128 meg card nvidia recommends you set the agp appeture to 128

128 is the most commonly recommended setting.
