Guest Willi Posted September 13, 2007 Report Share Posted September 13, 2007 Hi, i recently bought a dell xps 1710 equipped with a 7950 gtx 512mb gfx card (windows vista 32bit). when i realized the installed driver was over two years old i decided to upgrade to a more recent version. so i got the 164.01 driver instead. i was quite happy to see that everything worked out fine. usually I use my notebook as a desktop replacement and therefore use it only when it is plugged. when unplugged there are some really wierd errors on the screen. I took a photo with my digital camera in order to show you what it looks like. you can see that parts of the picture seem to overlap and reoccur. these only occur when using windows and standard applications. in 3d games and in photoshop everything is fine. alt-tabbing out of the 3d-application works fine for some seconds and the screen is ok but still only for some seconds. switching to the 3d-app again removes the problem. maybe you can help me? driver issue? thanks in advance!

Guest Windza Posted September 13, 2007 Report Share Posted September 13, 2007 I ran into similar issues on my Clevo 570 (7900 GTX) after playing with the power management settings - I have mine set to max performance for both AC and Bat for this reason (I barely ever use bat.) I'd suggest increasing some of the settings to higher performance and seeing if it makes any change, Cheers Quote Link to comment Share on other sites More sharing options...
Guest Guest Posted September 13, 2007 Report Share Posted September 13, 2007 Yea my XPS M1710 with GO 7950GTX did that, all you have to do is to get a different driver from this site. Quote Link to comment Share on other sites More sharing options...
zipper Posted September 13, 2007 Report Share Posted September 13, 2007 so i got the 164.01 driver instead. i was quite happy to see that everything worked out fine. 165.01? It's old; 163.14, 163.44 etc are months newer. Quote Link to comment Share on other sites More sharing options...
Guest Willi Posted September 14, 2007 Report Share Posted September 14, 2007 thanks for the replies. tried 163.67 but still doesn't work. also tried to change power management settings for pci-express in battery-mode but still didn't work. going to try the other drivers you mentioned or riva tuner (saw that in another topic) Quote Link to comment Share on other sites More sharing options...
theyeti Posted September 22, 2007 Report Share Posted September 22, 2007 Hi I have the same system as you and I've also encountered the same problem, but using the 163.44 drivers. Did you find a solution? cheers Quote Link to comment Share on other sites More sharing options...
GaryHawke Posted September 29, 2007 Report Share Posted September 29, 2007 I have the same laptop and have the same problem, I find if I turn the screen to medium (16 bit) all is OK Quote Link to comment Share on other sites More sharing options...
theyeti Posted September 30, 2007 Report Share Posted September 30, 2007 Hey Guys, I think I've found somewhat of a solution. Using the v156.55 driver does not result in this problem. I downloaded it from here ( http://forums.laptopvideo2go.com/index....showtopic=14837 )and used the original nv_dispd INF file. However, a drawback that I've just noticed is the apparent loss of 1440X900 and 1680X1050 resolutions! These are not listed as supported under Display Properties in System/Control Panel and, more annoyingly, do not appear as options in games such as Bioshock and MOH Airbourne! Grrrr!

Jon Posted October 2, 2007 Report Share Posted October 2, 2007 I am having exactly these problems. I have tried to change the battery power settings, to the same as the mains power settings, but the problem still occurs. (interestingly it does not happen until login, the Vista splash screen is perfect). I think I read that the DELL under-clocks the video card on battery no matter what, maybe that is the problem. I will try the 156.55 driver. I don't think I will miss those resolutions. Thanks, before I read this thread I thought maybe it was a memory problem.

Jon Posted October 2, 2007 Report Share Posted October 2, 2007 Hang on... 156.55 is listed with the INF not ready yet and is not listed in the main driver list. I found a reference to 158.45 drivers fixing this issue as well. I will try both and report back. Jon Quote Link to comment Share on other sites More sharing options...
theyeti Posted October 2, 2007 Report Share Posted October 2, 2007 Jon That's correct, there isn't a modified INF for this driver. Instead, you should use the original INF named "nv_dispd.inf" and found in the zip file "original_inf(s).zip" - which comes with the 156.55 driver. I've gotten round the resolution problem too by editing the nv_dispd.inf file in the following way before installing the driver: I replaced this section of text: HKR,, NV_Modes, %REG_MULTI_SZ%, "{*}S 1920x1200x64 1920x1440x64 2048x1536x64=1F;640x400 640x480x64 800x600x64 1024x768x64 1152x864x64 1280x800x64 1280x960x64 1280x1024x64=7F;320x200 320x240 400x300 480x360 512x384=F;SHV 1400x1050x32 1600x1024x32 1600x1200x32 1920x1200 1920x1440 2048x1536=1F;1400x1050x8,16 1600x1024x8,16 1600x1200x8,16=3F;640x480 800x600 1024x768 1152x864 1280x800 1280x960 1280x1024=7F;" with this: HKR,, NV_Modes, %REG_MULTI_SZ%, "{*}S 320x200 320x240 400x300 480x360 512x384 640x350 640x400=1FFF;SHV 640x480 720x400 720x480 768x576 800x600 852x480 853x480 854x480 864x480 1024x640 1024x768 1152x864 1280x720 1280x768 1280x800 1280x854 1280x960 1280x1024 1360x768 1365x768 1366x768 1400x1050 1440x900 1600x900 1600x1000 1600x1024 1600x1200 1680x1050 1800x1440 1920x1080 1920x1200 1920x1440 2048x1280 2048x1536 2560x1600 3840x2400x8,16,32,64=1F;" Hope that helps.

Jon Posted October 2, 2007 Report Share Posted October 2, 2007 Great! Those drivers seem to work. Thanks. Only one thing, the original nv_modes line in the copy I downloaded was: HKR,, NV_Modes, %REG_MULTI_SZ%, "{*}S 640x480 1280x768 1280x800x32 1280x960 1360x768x32 1920x1200=1;800x600 848x480 1024x768 1152x864 1280x1024 1600x1200 1920x1440 2048x1536=3B;{407-42D}S 640x480x64 1280x768x64 1280x800x64 1280x960x64 1360x768x64 1920x1200x64=1;800x600x64 848x480x64 1024x768x64 1152x864x64 1280x1024x64 1600x1200x64 1920x1440x64 2048x1536x64=3B;{407-408,40B-42D}S 1280x960x64=3A;{409}S 960x600x64=3B;{98-408,40B-53F}S 1280x960=3A;{98-39B,409,530-53F}S 1280x800x8,16 1360x768x8,16=1;" Your update worked fine and adds more modes.

Guest Soundso Posted October 3, 2007 Report Share Posted October 3, 2007 I have the same laptop and have the same problem, I find if I turn the screen to medium (16 bit) all is OK This deactivates the vista aero desktop, which seems to cause driverconflict.

Valmont Posted October 11, 2007 Report Share Posted October 11, 2007 Hi Is there any driver newer than 158.45, that works without this screen corruption? Quote Link to comment Share on other sites More sharing options...
GWolfman Posted October 15, 2007 Report Share Posted October 15, 2007 (edited) HiIs there any driver newer than 158.45, that works without this screen corruption? Anyone have an answer to this? I just tried 163.69 and I get the same corruption like in the screenshot above. I will try 156.65 and see how it goes. If not, then 156.55. :) UPDATE: I just tried 156.65 and I still had the same issue. Giving 156.55 a try UPDATE2: Just installed 156.55 and it works, but are there any better/newer ones that work properly?

Valmont Posted October 16, 2007 Report Share Posted October 16, 2007 (edited) Just installed 156.55 and it works Yes, it works without corruption - but PowerMizer is disabled (doesn't change core/memory frequency in 2D). Therefore, 158.45 still the latest good driver with full mobile support. UPDATE: After ~4 hours on 156.55 corruption occured...

Valmont Posted October 17, 2007 Report Share Posted October 17, 2007 http://forums.laptopvideo2go.com/index....showtopic=15455here is what is causing the problem Thanks, but if i don't want to flash unlocked video BIOS and change the clocks, there is no way out than stay on 158.45. Even disabling PowerMizer in INF doesn't save from corruption - tried on 163.75. Quote Link to comment Share on other sites More sharing options...
mobilenvidia Posted October 17, 2007 Report Share Posted October 17, 2007 In 163.75 the problem is fixed just the older series drivers 156.xx where the only known fix for now is the BIOS Memory clock to 120Mhz+ The 163.xx fixes in other link work, even tried on a M1710 (debaucher) Quote Link to comment Share on other sites More sharing options...
Valmont Posted October 17, 2007 Report Share Posted October 17, 2007 The 163.xx fixes in other link work Not at all - i tried yesterday evening. Quote Link to comment Share on other sites More sharing options...
mobilenvidia Posted October 17, 2007 Report Share Posted October 17, 2007 Your problem is then not the same as the M1710's go7950 problem. But probably similar. Powermizer will probably be to blame here as well, and the battery memory speeds will be too low. The disable powermizer, I mentioned in another thread does this work (even though battery power will be used faster) ? Quote Link to comment Share on other sites More sharing options...
Valmont Posted October 17, 2007 Report Share Posted October 17, 2007 Your problem is then not the same as the M1710's go7950 problem.But probably similar. I think my problem is the same - corruption happens very often (~ every 2-3 minutes) on desktop when the clocks are reducing. However... The disable powermizer, I mentioned in another thread does this work (even though battery power will be used faster) ? ... disabling PowerMizer in INF make life little bit easier - corruption happens after 1 hour or more. Strange situation - the clocks shouldn't be changed. Quote Link to comment Share on other sites More sharing options...
mobilenvidia Posted October 17, 2007 Report Share Posted October 17, 2007 It could be combined with the OS's power saving features. Quote Link to comment Share on other sites More sharing options...
GWolfman Posted October 22, 2007 Report Share Posted October 22, 2007 So I should use 163.75 and it'll work ok? Side note: When I use powerdvd 7.3 to play HD DVD movies on my laptop, powerdvd closes after a few seconds of play or so (after the movie/main title starts) without any errors. I think it might be all the VC1 encoded movies. When I play blu-ray movies, it works perfectly fine. Any idea what's going on there? Quote Link to comment Share on other sites More sharing options...
