To Whom It May Concern:

I have an issue with my EVGA GTX 280 SC, regardless of the driver installed I get a BSOD with nvlddmkm.sys error and a memory dump. It works just fine with the 6600GT I used as an alternative. I just wanted to know if anyone else is gettiing

Hi
Since Last Saturday 27th Feb 2010 a normal running Dimension 9200 under retail version of the Win 7 x64 Ultimate started to through BSOD with Nvlddmkm.sys error and a memory dump.
I could not run my Win7 OS cd to boot to do a custom install as during the phase of completing the installation BSOD with a memory dump and it reboots again. This cycle keeps repeating. Since I have started the custom install with a format I have lost the ability to start in safe mode either.
Luckly I have has a system image back up and able to use the repair option to install the Image backup but that too on reaching the Win 7 logo throughs a BSOD with Nvlddmkm.sys error and memory dump. This goes in the loop of boot,BSOD and restart.... Now again I on safe-mode managed to reach the Device Manager and here uninstalled the Nvidia driver.Then on re boot, on the basic drivers computer did not BSOD. This confirmed that the driver built in Win 7 OS CD for some reason having problem with my Nvidia Geforce 1GB 7950 GX2 GPU.
I installed the Dell's Vista x64 version of the Nvidia driver under safe mode at this point. This has now allowed me to operate my Win 7. When I went to Device Manager, I find under the display device only one 7950GX2 [Here I use to see 2x 7950 GX2 in the past!!]

The first suspect is half of my Geforce 7950 GX2 is not functioning and does not like the latest drivers but the old Dell's version of Vista x64 driver for some unknown reasons.

I intend to replace with a new GPU and try again.

Thanking you.
Regards

You should have started your own thread. This thread was about TDRs (Timeout Detection & Recovery). However, u should have 2 7950gx2 showing up in the device manager. Maybe your card is dying. Re-seat the card and check it's power.

This thread was about the nvlddmkm.sys BSOD issue. TDR was just one suggested culprit. See quote below.

Anyway, I started having this BSOD on bootup a while back... after a windows update. Basically, I was having to boot from a previous restore point just to get into windows "normal" mode. Today, however, the restore points no longer worked... just kept BSODing on boot with a nvlddmkm.sys error. The tdrlevel=0 tweak did nothing for me... neither did rolling back/updating my nvidia drivers... or clearing out all the non ms startups in msconfig. Finally, figuring one of my 275s was bad, I disabled the secondary card in the device manager while in safe mode and found I could boot normally again. At that point, I removed and re-installed the current nvid drivers for both (again) and found that the sli option was missing from the nvid control panel. While researching this new problem, I found the simple solution was to roll back the realtek lan drivers to a previous version in device manager. Apparently, there is a conflict between the windows7/vista lan and nvidia's gpu drivers that causes nvlddmkm BSODs, (found this on the EVGA site and Tom's). Anyway, since I rolled my realtek lan driver back, I've had no more of these blue screens.

I'm not sure if this will help all of you guys out, since some of the earlier posts were well before the windows update that I was having issues with, but it wouldn't hurt to try. If it doesn't work, you can always just restore the lan drivers.

Edit: Oh yea, for what it's worth, I'm running win7 64 with a coupl'a gtx275s.

I just ran across this problem last night and also found that the latest Realtek LAN drivers that Win 7 wants to install appear to be the culprit. The

latest on EVGA's site (which are older) seem to work fine. If anything changes I'll update in this thread.

Rich,

We all know how frustrating BSODs can be, one sympathizes. Are you having the nvlddmkm.sys issue? Have you tried rolling back your realtek LAN driver in device manager? Since I did this, I've been completely BSOD free... this driver and some Nvid drivers don't get along.
