video bios editing

i was looking at just messing with the video bios since i can't seem to find any other way to set custom clocks.

however, the apple video bios seems to be different than the standard bios. it comes up all corrupted. any ideas on how to overclock my macbook pro in windows XP?

 

hmm? the machine that's a fruit doesnt have something like riva tuner or ntune or similar for you? Apple may have used a custom bios to ensure you couldnt overclock.

 

you can over clock but it gets reset after reboot. Is that what you are talking about masterchef? Isnt it the same for all laptops?
Messing with the bios means it would always be overclocked. Might also mess up power saving. Not sure if its a good idea.

 

i currently cannot over clock at ALL.

can anyone on windows xp?

if so, what drivers are you using?

apple doesn't support windows, obviously. there might be a utility for mac osx, but i am not certain. i would expect ntune, atitools, and riva tuner to work, but i am starting to think that apple is using a custom bios that those programs don't work properly with.

apparently the story is different in vista, but vista has a completely different way of interacting with hardware (thats why there is/was a massive driver problem with vista)

so i am looking for either a utility that allows overclocking in xp on APPLE hardware, or something to edit the clocks permanently in the video bios.

 

I can overclock with the bootcamp drivers and with the 158.51 drivers from laptopvideo2go. I use ATITool but i also tried Rivatuner. Both worked but i just liked ATITool better.

 

I read a thread a while back by LightofHonor89, who also used the Boot Camp Drivers (101.34) to overclock: MBP Overclocking Benchmarks.

 

is that with the 8600m gt santa rosa gpu in windows XP?

i will try 158.51, although it didn't work the last time i tried it. system locked up...

 

158.51 gave me the Infinite Loop Error too.

LightofHonor's thread is with 2.4GHz (256MB 8600m GT) MBP in Boot Camp 1.3 (ForceWare 101.34) and Windows XP Pro. It shows before and after results. Before clock sppeds were 470/635 and after were 590/700. In 3DMark06 @ 1280x1024 the score improved from 3741 to 4457.

I think that's close to what the 8700m GT makes in 3DMark06 !

There is also some in-game information, nice thread.

 

i am currently doing a registry clean on the remnants of the 162.18 drivers. after that i will try to put on the 158.14 or whatever drivers and see if it doesn't freeze.
