Im trying to overclock the 8600GTin Vista and going nowhere fast. I have the latest 163.69 drivers and Im using Laptop2go .inf to alter the drivers.

I am trying rivatuner 2.04 and the newest atitool as well to no avail, as it simply resets to the preset speed

Has anyone had any luck overclocking this 8600GT in Vista?


Thanks in advance!
 
The >160 drivers are locked for overclocking.

The default bootcamp driver will work though.

PS ditch vista and go back to xp pro, much faster and cleaner. Plus if your working with any programming the Nvidia cuda library works.
 
I hate vista too but Its a must going forward . Either way how are they locked? I overclock on my gaming system which is an 8800GTX in SLI with vista and the same drivers. Works fine..
 
Have u been to the nvidia forum's.

I heard all the > 160 drivers were locked, i didnt confirm becuase i have a Quadro FX 5600 / 1.5gb frame buffer and a 8600m gt 256mb and they were both locked when using the > 160 drivers.

On the regular bootcamp driver it worked fine.
 
I have the 169.47 drivers installed on Vista on my Penryn MBP. Like the OP, I can't overclock with ATI Tools. Are there any other programs that could work? Or do I have to rollback to the original boot camp drivers in order for me to OC the card to its intended settings.

Well if your using ATI tools to overclock a nvidia card that just won't work will it?
 
Superspiffy, what do you mean by "you can't oc" ??

I have the exact same MBP as you (AWESOME btw) and I had issues overclocking with RivaTuner, and by issues I mean I used to set the clocks to higher values but it would always reset it to the default ones.

I fixed this issue by using nTune which is also nice. Easy to use and provides a system monitor as well

I'm using 174.74 (which gave me some improvement with Crysis w/o oc) btw but Let me know if it works.

Where did you get 174.74 drivers? Link? Modified inf?
 
Overclock MBP

Did a brief search, if this has been thoroughly discussed on another thread, my apologies.

I was wondering people's responses (aside from it's illegal, just don't do it people) in regards to overclocking the GPU on your Macbook Pro. I know the GPU is severly underclocked. Here is my system:

November, 2006 MBP version:
2.33 Intel
2 GB SDRAM
RadeonX1600 GPU 256 MB

I have a couple questions regarding:
-Is the underclocking due to heat or battery usage?
-What are people's experience with heating issues after OC?
-For the x1600, is there really that much performance upgrade?
-The biggest thing I need it for is probably an assortment of Adobe products and Sketchup. I do AutoCAD in Bootcamp too, but I don't think that's maxing anything up.

There is a 2D clock (when running in desktop in XP) and a 3D base clock for running desktop in Vista and basic graphics. Then there is maximum clock, which is when the GPU clocks up when it's needed.
 
Erratum

After few extra days testing my OC, i am not sure why but nTune doesn't let me OC anymore....It's weird.

So I replaced my 174.74 driver by the 169.04 which the one that works the most often by looking at people's experience in forums

And it does. First crash for me at 620/850. I guess laptop crashing means OC working.....
