Newest NVidia drivers (179.24) on D830 with Vista64

Has anyone noticed, that after installing newest drivers (179.24) on Vista64 color depth is reduced to 16 bits and you cannot change it? I've got WUXGA display, 4GB of RAM and NVS 140M. BIOS is updated to A14.

Dell Support told me that this can be caused by some other software on my machine, but my colleage is having the same problem on his D830, and i've also found thread similar problem somewhere on the internet. I've uninstalled older drivers and even tried to install 179.29 with modified inf with no luck. I'd say that BIOS is causing this, maybe not enough RAM is reserved and new memory management implementation is used, and if more users experienced same problem Dell can fix it Smiley Happy

Re: Newest NVidia drivers (179.24) on D830 with Vista64

I've had the same problem here with the 32Bit Version of Vista and the new official Dell Driver. Also using modded Versions of 178.26, 179.28 and 179.29 doesn't help.

After Driver-deinstallation and going back to 174.31, the 32 Bit Mode is now available :-)

P.S.: Maybe the ServicePack (Build 6002) causes the problem?

I'm not so sure about SP... It seems that this is either bug in bios or bug in nvidia drivers, because modded drivers do not work as well. You've got 1920x1200 (WUXGA) LCD?

My colleage tried to override settings in nvidia control panel and it worked, but not for 1920x1200.. I think that 1680x1050 worked as this is next 16:10 resoultion.

Re: Newest NVidia drivers (179.24) on D830 with Vista64

blazeu - thanks for pointing me to your thread - i'll watch to see if there are any solutions.

As you noted, i have the same issue but like the person before me, I have vista 32-bit as well. Also have the WUXGA LCD (1920x1200), 2.5 ghz, and 4gb ram.

I rolled back to the earlier video driver so the display is fine but the old driver still gives me audio distortion problems (figure that out....video gives audio problems...nothing is simple!)

Hopefully they'll roll out a new video driver soon and solve both issues. Wish I had a solution for you two.

Re: Newest NVidia drivers (179.24) on D830 with Vista64

I am having the same issue on Vista 64bit and the A14 version of the bios. I tried installing the older driver, and even though I am now able to select 32 bit color depth, There are issues with moving windows and scrolling... very laggy...

 

There is an obvious issue here some where.

Re: Newest NVidia drivers (179.24) on D830 with Vista64

I used update R205371.EXE.  I had the same problem with 16-bit as my only option. Also, my desktop would lock up and I would have to end explorer.exe. I thought this was due to my dual monitor setup so I uninstalled the driver through Add Remove programs. After the reboot, Vista said there was additional software that needed to be installed and requested another reboot. Now I get 32-bit color but programs like Firefox and various administrative tools are locking up. Just now I right-clicked on the desktop to try to get the exact model of the video card and it is locked up. This is killing my productivity. I have a D830, 4GB RAM, NVIDIA Quadro NVS 140M with Vista 32-bit SP1.

So? No response from Dell? I've tried contacting TechSupport, but they told me that no such problem exists and i should reinstall my windows Smiley Happy

Re: Newest NVidia drivers (179.24) on D830 with Vista64

I had the exact same issue on Vista 64 bit on a Dell 830 with WUXGA and BIOS A14.

 

I resolved it by getting the 176.44 drivers from laptops2go .com

 

hxxp://www.laptopvideo2go.com/forum/index.php?showtopic=21361

 

(change http)

 

Those drivers worked just fine for me and actually seem to work better than any I've used in the past so I'm not even going to bother messing with Dell support over this.

 

 

Oh, btw, it seems that the "16 bit problem" is only for the actual laptop display.  A connected external monitor or 2nd external monitor will display in 32 bit mode just fine.

blazeu,

 

I do have an open case with Dell... I am a Larg Ent customer and I made a big stink about this... they have admitted there is an issue here... no word yet on a fix. However, when I do learn of a fix, I will make sure I post it.

I have the same 16bit color depth issue with this driver under the following OS:

Windows Vista Enterprise SP1 x86
Windows Server 2008 R2 x64
Windows 7 x86

If anyone has a fix, workaround or a better driver, please let us know.
