Geforce 3 Ti 500, Riva Tuner 8.2, 23.11 drivers.
AMD 1.4
512MB
I reformated my hard drive and before I used to be able to force sideband addressing , (Thru Riva Tuner)now when I try to force it, the PC will not rebbot with the drivers and It will reboot in Safe mode.And I need to re install the drivers
In the info from Riva tuner says Sideband supported / disabled.
Any ideas how to fix this?
I really noticed , since I dont use V sync so I will like to have this option again.
hope someone can help.
Also I used to be able to overclock to:259/572 and now at those speeds a get graphics problems so had to turn down overclocking to 250/540.
I changed the Via drivers from 4.35 to 4.36
I tried finding in the Bios sideband adressing to enable it but no luck.
Is there a way?

Nvidia reccomends disabling side band address because it causes problems and many of the nvidia drivers make sure its off.SBA max may give you a 1% improvement in performance so its hardly worth worrying about.Fastwrites by far are the most productive seting outside of just ovrclocking you card which can gain you 20-50% improvement in speed if the game is optimized for the gf3.So again do not use SBA and you will find your pc is just as fast and alot more stable,CC

Fast Writes is hardware supported but dissabled by the driver, can I force it ON?
Or how can I enable in the Bios so is supported by the driver(Its already enabled by the Bios)

Is anyone else tired of performance features that you can't use? If they don't work reliably, leave them out. We've got all these tweaking sites mouthing off about 30 things you can do to get 0.2% more performance and half of them lead to instability.

Do what u want, but i tell u what all the others said allready: Both SBA and fastwrites are not worth the system instability they give. Even if u are able to get them both enabled at the same time, you'll be extremely lucky if u get one aditional fps. I benchmarked all free main tweaks (AGP4X, SBA, FW), and believe me, the difference between the 3 enabled at the same time, and the 3 disabled, do not give u 1 single percent of aditional performance. I tried this with 3 different cards on my system. Plus, with my Geforce 3 Ti200, SBA costed me 10 points in 3dmark2001.
Hope this helps any,
Ric.

The only way to enable the Geforce 3's FW and SB abilities is to hack the card's BIOS, voiding your warrenty. FW and SB are basically worthless (IMO, SB is asking for trouble, as it messes with your memory pipeline, which can seriously destablize your system).
If you were to look at the bandwidth numbers (real life, not theorical - the other system components will limit your bandwidth) from running a PCI card vs AGP 2x vs AGP 4x with and without FW and SB, you'd find that they are similar. I know the moderators have a definite view on this, and a few know what the numbers are.
Now, if your absolutely dead-set on turning on FW and SB, head over to forums at nvnews.net or amdmb.com and ask around. They have the tools and can tell how to do it. HOWEVER, you can say goodbye to your warrent and there is a fair to high risk of you destroying your graphics card.

Yes you can force fastwrites but i agree with the others it isnt worth it and many believe including myself that because of the gf3s unique memory design that both fastwrites and SBA should be off.SBA is a isa remnant from the past providing a 8bit pathway thats way to slow to be helpful and can cause problems.Fastwrites is a Pci controlled feature from pre agp days and frankly its too slow for todays apps.
Today your videocard does everything itself includeing cacheing and textures because the vram is much faster than pushing data back and forth from system ram so most of these features are worthless.
Alecl Im with you,I thought the point was to play games and have fun not spend hours trying to find a marginal performance increase.Most videocards in todays games are within 20% of each other because very few games are optimized for gf3 cards so tweaking wont help sometimes.
Gf2 ti cards outperform gf3 ti 200 cards in non gf3 optimized games because the gf2 ti has a 250-275 gpu versus the 175mhz gpu on the gf3 ti 200 and no amount of fixes will change that fact.
Game engines vs the type of videocard/drivers determines alot of how well a game will perform and no one card will perform well in all games.Relax and play a game,CC
