XP MCE - BSOD 0x50 - ati2mtag.sys

Recommended Posts

I've got a slight problem with a new system I've got setup. System specs are as follows:

Gigabyte GA-MA78GM-S2H

AMD X2 5200+

2x1GB OCZ Gold DDR2-800


Pioneer DVR-212D

Antec 380W PSU (came with NSK2480 case)

The system is connected from the onboard video to an LCD TV via HDMI. All standard stability tests (memtest, Prime95, etc) run without any errors or hiccups.

The system stays on 24/7, since it acts as the media center as well as a backup server and central file storage for the household. Every so often when the system is idle, it will bluescreen with error code 0x50, pointing at ati2mtag.sys as the culprit. I've attached a complete memory dump here (12.3MB 7-zip compressed).

All the drivers, as well as the motherboard BIOS, have been updated to the latest version. The system is running XP MCE 2005 SP3.

It seems as though the graphics are to blame. I've heard that ATI and HDMI still don't always play nice, so on my list of things to try in the near future is the following:

  1. Connect the system using a DVI-HDMI cable instead of the straight HDMI cable
  2. Install a dedicated graphics card (both ATI and nVidia) and connect it via DVI-HDMI
  3. Connect the system temporarily to a regular monitor via DVI and see if I can reproduce the problem

I was hoping that someone might be able to have a look at the memory dump mentioned above and figure out if there's anything else software/driver-wise that I can try in the meantime.

Probably want to try compressing and uploading again:

This was also seen in atikmdag back in 2006 (I remember it vividly, still have a dump file) that was fixed when ATI released of that driver (for x64). Note that both caused a page fault by trying to access a memory address that was either paged out or invalid (thus a page fault, thus a 0x50 bugcheck), for clarification on the crash. So, here's *your* callstack, which is awfully close to the *old* callstack I've got (I'll post them both for comparison):

I'd say an email or phone call to AMD/ATI is in order, as it looks like this is still broken in a different driver. Good luck.

Thanks for the info. I've contacted ATI support and have an open ticket at the moment. I'll keep this thread updated with the responses as I get them. :)
