My 260.99 for Dell XPS L501X

Recommended Posts

First, big thanks to Nautis1100 for the plethora of info; very informative!

I've tested the drivers and it all works nicely so far.

Please let me know if I've done something horribly wrong.

260.99 Verde, modified for use with Dell XPS L501X & (only) GeForce GT 420M

Supported OS:Windows 7 64-bit

My system has a 420M, so that`s what I modified. It`d be pretty easy to modify the 435M, so feel free to do so.

Step 1 - Download 260.99 Verde from Nvidia's site

Unpack

navigate to unpack directory, ie - ...\NVIDIA\DisplayDriver\260.99\Vista 64-bit\International\Display.Driver

Open nvac.inf

Step 2 - Add the following anywhere in the [NVIDIA_SetA_Devices.NTamd64.6.1] section

[NVIDIA_SetA_Devices.NTamd64.6.1]
%NVIDIA_DEV.0DF1.23% = Section016, PCI\VEN_10DE&DEV_0DF1

which, as Nautis1100 has taught us, leads to [section016]. It should already look like this, just pasting for reference

[section016]
AddReg = nv_DRS_addreg
AddReg = nv_commonBase_addreg
AddReg = nv_commonDisplayModes_addreg
AddReg = nv_controlPanel_addreg
AddReg = nv_global_addreg
AddReg = nv_miscBase_addreg__16
AddReg = nv_opengl_addreg
AddReg = nv_timingRestrictions_addreg
CopyFiles = nv_Drs_copyfiles
CopyFiles = nv_controlpanel_copyfiles
CopyFiles = nv_detoured32_copyfiles__02
CopyFiles = nv_detoured_copyfiles__02
CopyFiles = nv_license_copyfiles
CopyFiles = nv_nvsmi_copyfiles
CopyFiles = nv_sysDrivers_copyfiles__02
CopyFiles = nv_system32_copyfiles__03
CopyFiles = nv_syswow64_copyfiles__03
DelFiles = nv_sysDrivers_delfiles
DelFiles = nv_system32_delfiles
DelFiles = nv_system64_delfiles
DelReg = nv_clearRegistrySwitches_delreg
FeatureScore = E6
NVBusUpperFilter = nvpciflt
NVForceClean = 1
NVSupportOptimus = 1
NVSupportPhysx = 1
RegisterDLLs = nv_common_registerdll__02
AddReg = nv_HDAudioInstall

Step 3 - Search for / navigate to [nv_miscBase_addreg__16] and replace what's there with...

[nv_miscBase_addreg__16]

Thank you very much. I have bought Dell XPS L501x for CUDA debugging and I was disappointed with the inability to update the driver to 260.99 version. It wasn't easy to find your solution.

I'll do tested it and then I'll give you my feedback. The first CUDA tests results are OK.

Now, I'm trying to do the same with linux (Ubuntu in my case) because I only use windows when I need Visual Studio (not possible with Eclipse yet).

Thanks. Go on!

Hi again.

First issue: now the system doesn't show any information about the device but 1 GB of memory. With the DELL driver it showed that the device could use 3GB of shared memory with the system.

Any idea?

Thanks.

420M only has 1GB discreet memory.

Thanks.

Shared does not give you any results at all. No matter how much shared I have I always get the same results in games. See I have 128MB dedicated and 703MB shared. With GPU monitoring software the GPU never ever uses more than 128MB even under a intense load. (Specifically Fallout 3 on a Geforce Go 6150. Can you imagine?)

I also always have the same FPS.

Just did a clean install of Windows 7 Pro x64 on a Dell XPS 15 L501X laptop. Installed all the latest driveres following Dell "Driver Install Instructions".

I have problems with my Nvidia GeForce GT 420M video card.

In Device Manager it is showing as installed and working properly. But when I go to the Desktop to adjust the screen resolution, the card doesn't appear.

All I'm shown is the "Generic PnP Monitor on Standard VGA Graphics Adapter".

When I right click on desktop I don`t see any nVidia Control Panel (like I see on my old Inspiron 1520). I tried to manually install nVidia Control Panel using NvCplSetupInt.exe located in C:\dell\drivers\R292130\Display but I recived this message "Setup failed to read the required Display Driver to be used with this package."

Uninstalled the video driver that Dell provides on their website. Then I went to nVidia and downloaded and installed their latest driver for my specific card. Received this message: "This graphics drive could not find compatible graphics hardware".

I replaced nvac.inf with the one you provided. The driver has been installed succesfully but now I have again the first problem (the one discribed in the first half of the post).

Some advise please ?

Thanks.
