Diagnostics

From time to time all of us experience seemingly baffling failures of the [email protected] Clients. With multiple clients on the same machine, figuring out what's wrong becomes complicated. Many of us turn to the forum for help. Unfortunately, all too often, their request for help post reads something like " It won't work. What's wrong?" and that's it. Here are the basic's of what is needed to properly diagnose a problem.

1. All clients should be run with the -verbosity 9 flag in extra parameters.
2. Machine Specs

a. CPU @ GHz
b. GPU(s) @ core/shaders/memory, what you set and what they're running as reported by a monitoring app like GPU-Z or Afterburner.

3. Software

a. OS and Version
b. GPU driver version

4. The log at the start of the client including the banner.

This failure was due to a faulty GPU core on a single PCB GTX295 running SLI (Multi-gpu). Disabling Multi-GPU in nvidia control panel and folding only on the good core fixed it.

7. For configuration issues, the client.cfg of each client on the machine (I use NoteTab Light to correctly display this file)
Code:
[settings]
username=ChasR
team=32
passkey=5d4520daa6737d909fbdf6f72088XXXX
asknet=no
machineid=2
bigpackets=big
extra_parms=-gpu 0 -verbosity 9 
local=8583

[http]
active=no
host=localhost
port=8080
usereg=no
proxy_name=
proxy_passwd=

[core]
priority=96
cpuusage=100
disableassembly=no
nocpulock=1
checkpoint=30
addr=

[power]
battery=no

[clienttype]
memory=500
type=0

Armed with the above information, most problems can be diagnosed quickly. With a few other questions answered, like "what does task manager say?" and "did you do a clean driver install with driver sweeper run in safe mode?" the member looking for help can get it within minutes instead of hours or days.

Feel free to post up anything you think I left out

Ya that's on my to-do list, I have been meaning to re-do all of the FAH install info, troubleshooting, etc.

Guess I need to get on that soon...
