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 fastwrite is supported but yet it is disabled.

rivatuner... notice the greyed out area

i myself just diable fast write even if i can ebable, it decrease my stability when the video card is overclocked, and there are hardly any performance increase from enableing fast write

by the way i have a ti4600

I answered this in Addaboy but.. anyway..

That mobility doesn't support fast writes.

ATI actually say that their cards don't support fast writes. For stability especially, they recommend them off.

Why would it say on wcpuid that it supports it if it doesnt actually?

Maybe it's there but it can't be changed.

wcpuid says the [i]chipset[\i] supports fast writes, not the card itself.
