Trouble Enabling Fast Writes

DoM-aL

Specs: HP Pavillion ze5185 laptop P4 2.4 100 mhz Fsb 512 ddr 266 ATI Radeon Mobility M6 32mb 60 GB Hitachi HD.

Ok well here's the issue i was looking for ways to improve this laptop. I opened up wcpuid and looked at chipset info and i saw that agp fast writes was disabled. I then went into the bios to search for a setting, but you know laptop / proprietary computer companies' bioses are not well documented. I didn't find any setting in there.

So I figured I could change it with RivaTuner, but in rivatuner it is all greyed out so i can not select it.

Next on the list was rage3d. I searched around but could not find any settings.

There was also nothing in settings that had anything to do with fast writes, so i'm asking you. Is there some sort of way that i can get fast writes enabled perhaps a registry hack, perhaps by disabling something?

Any ideas are much appreciated.

Here are the pictures of display settings, wcpuid chipset info, and rivatuner.

wcpuid notice that fast writes is supported but not enabled

Rivatuner Notice the greyed out area

If its not in the BIOS then it is locked off for stability reasons.

First the card needs to support it
Then the motherboard needs to support it
Then it has to be turned on in the BIOS
Then it needs to be enabled/forced on with the drivers

If any of those are a no then it wont work. Same for sideband addressing.

I wouldn't worry about it too much. With ATI cards, fast writes don't give you much of a performance boost.

I actually read somewhere to not enable fastwrites with ATI cards.
