MrMage Posted July 23, 2007 Report Share Posted July 23, 2007 (edited) Hi Guys, I have the following problem: On my NB (see left) with Geforce 8600M GT with 256 MB GDDR3 (that's what Rivatuner tells me, officially it just has DDR2 ^^), whenever I try to change the OC settings in Rivatuner, those settings are immediately lost when I return to Rivatuner. Additionally, the monitor Core Clock Feature of Rivatuner tells me that my GPU is running at 513 MHz when the default should be 475 MHz,even with overclocking disabled! When trying to overclock via the nVidia CP, it tells me that the overclock test fails. This issue has appeared with driver versions 101.17, 101.19 (a special driver for an 8600M GS on a Samsung NB) and 158.22. But I actually installed all those drivers with the setup.exe, not with the Refresh drivers function of the Device Manager. Should I completely uninstall the drivers (including registry settings) and then reinstall it via Device Manager? Or is the problem a different one? BTW: Some other guys managed to overclock the graphics card and it seems to be always working with the preinstalled copy of Vista Home Premium. I installed XP Pro on the laptop. Thank you, Daniel Edited July 23, 2007 by MrMage Quote Link to comment Share on other sites More sharing options...

Thank you, Daniel myself and others have had the same problem with the Macbook Pro and XP pro. The overclocking settings in rivatuner will reset after reboot. I was using 162.18. Others have yet to find driver that allow you to overclock in XP Pro. Someone was able to overclock in Vista 64 Quote Link to comment Share on other sites More sharing options...
zipper Posted July 25, 2007 Report Share Posted July 25, 2007 I made some trials with 15x.xx and 10x.xx drivers but found that overclocking with RivaTuner didn't work at least on those I tried (WinXP). So I went back to 97.92, a reliable driver. Quote Link to comment Share on other sites More sharing options...

Thank you, Daniel You can Overclock easy with VBIOS Flash and this way will be better then Driver overclock because in some drivers overclock didn't work like you may see.. backup your VBIOS and upload here.

bobz99by Posted July 25, 2007 Report Share Posted July 25, 2007 How does one backup the VBios...through the regular bios? I'm also on a macbook pro so I'm not sure how to access my BIOS. On my desktop, i know it shows a note "press XX to access bios" during startup. Quote Link to comment Share on other sites More sharing options...

bobz99by Posted July 25, 2007 Report Share Posted July 25, 2007 thanks a bunch ganstaone. I'll try this out when i get home from work. Are there any risks associated with flashing the vbios aka permanent damage? Quote Link to comment Share on other sites More sharing options...
bobz99by Posted July 25, 2007 Report Share Posted July 25, 2007 Yea on second though I think I'm gonna try to upgrade to Vista 64 and use drivers I know I can overclock on. I don't want to risk flashing my gpu and screwing it up. An interesting method though. Thanks for the help. Quote Link to comment Share on other sites More sharing options...

Ok but with flash it's more safe for you GPU then driver's this is my opinion anyway will you upload your BIOS i'm curious to have a look Quote Link to comment Share on other sites More sharing options...

Sorry but you will have to wait to come out new version of Nibitor because last Nibitor v3.4a don't suport your GPU... :) You will have to use driver overclock option if your GPU BIOS is not locked Edited July 26, 2007 by GanGstaOne Quote Link to comment Share on other sites More sharing options...
zzpulp Posted July 28, 2007 Report Share Posted July 28, 2007 If you are willing to flash your GPU (which should be your last option I guess) then I'd recommend using nvflash first and foremost. nvflash --list nvflash -c nvflash -b orig.rom nvflash -k orig.rom The first command checks to see if nvflash recognizes your gpu as working nvidia. Use the second command to see if nvflash supports your eeprom. Use the third command to backup your bios. Use the fourth command to check the bios dump you made in the third command to the eeprom nvflash reads. The fourth command is really just to make sure nvflash doesnt have an error in writing your bios to the disk. Then you can post your orig.rom here and tell me the default frequencies. I'll hex in whatever clocks you want and make the new checksum. I would upload some kind of exe to do this but nibitor is a highly updated tool and I'm unsure if clocks have been saved in the bios the same way throughout time.

MrMage Posted July 28, 2007 Author Report Share Posted July 28, 2007 I don't want to flash my Video Card BIOS. And some people in a different forum reported that they weren't able to extract the BIOS with nvflash yet since the card is too new. But some people reported that they could overclock the card in my Notebook (they've got the same) but then accidentally updated the driver and lost the old one. I would try 97.92 but that version doesn't support my GPU :-( Any other ideas? It is possible - some people managed to do it but they lost the driver which was able to do overclock. And, by the way, the settings do not reset after reboot but immediately after closing Rivatuner. And when I try to set the overclocking with ATITool, the OC settings get lost after clicking on "Set Clock". Quote Link to comment Share on other sites More sharing options...
MrMage Posted July 30, 2007 Author Report Share Posted July 30, 2007 OK, I got it. The driver from http://www.forumdeluxx.de/forum/showthread.php?t=372044 (Download: http://rapidshare.com/files/40371139/NVIDI...1.119.rar.html) did help. I had to uninstall the old drivers and use Driver Cleaner.Now i get 600/500 instead of 475/400 (Core/mem). Quote Link to comment Share on other sites More sharing options...

MrMage Posted August 6, 2007 Author Report Share Posted August 6, 2007 Now I use http://forums.laptopvideo2go.com/index....showtopic=14222. Its even better because it recognizes 2D mode when not on AC and I can use my external screen as primary device. Quote Link to comment Share on other sites More sharing options...
