high CPU on nvlddmkm.sys

19 posts in this topic

Hi

i have a freeze of my computer after the boot.i have installed Windows SDK et Latencymon.: congratulations to magicandre concerning the topic on the use of SKD!!!

i see high cpu consumption on nvlddmkm.sys: all my Video driver for a Nvidia GT6600 are up to date: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 285.62 , NVIDIA Corporation...

what to do to avoid this ?

what is funny is that: after the feeze.. all seems to be OK execpt the permanent Highest DPC routine on this driver all daylong!!!

i can't upload the trace.. tto big !

try older versions, too and check that the graphic card doesn't share a IRQ with other devices.

hmm, I can't see a conflict.

try the inbox driver ("C:\Windows\winsxs\amd64_nv_lh.inf_31bf3856ad364e35_6.1.7600.16385_none_4a5c7d78e486512b\) and capture a new trace. You can compress the file as 7z/RAR and upload it to mediafire.com. YOu can send me the link so that I can look at it.

use the inbox driver because MS provides Debug data for the driver.

Run this command:


xperf -start perf!GeneralProfiles.InBuffer && timeout -1 && xperf -stop perf!GeneralProfiles.InBuffer nVIDIA_issues.etl

Compress the nVIDIA_issues.etl (only this file) and upload it.

Why don't you use the buildin GPU (Intel HD 2000 which is embedded into your Intel i3) ?

btw have you have made a trace which captured the issue?

Your Intel® Core i3-2100 CPU @ 3.10GHz contains the Intel HD 2000 graphic:

http://ark.intel.com/products/53422/

http://www.intel.com/support/processors/corei3/sb/CS-032275.htm

if you use a motherboard with Intel z68 or Intel H67 chipset you can use this included graphic unit. If should be fast enough for office usage.
