People willing to test nvclock

[Thunderbird]

It has been fixed in cvs.

[DuGi]

hmm... it's nvclock output from latest cvs compiled few minutes before i wrote post above.

Just updated from cvs. It appears i have 50c in nvidia-settings
and GPU=45c board_temp=40c in nvclock. Also i am forcing 90%
fan speed but it says here it is set to 'auto'. Fan speed is
correct though.

I have added a bunch of fixes and temperature reporting of LM99/ADT7473/MAX6659 sensors used on geforce6/7/8 boards should be correct now.

They match up here now.

The number of stream and rop units wasn't correct on most geforce8/9/gtx cards. I have fixed that in cvs and hopefully it is correct for everyone now.

On my card nvclock and nvidia-settings are now much closer, but there is still an occasional difference of 1C, which may be considered acceptable. Also, on a few runs of nvclock -T, the output was completely weird:

user@host:~/src/nvclock/nvclock/src$ ./nvclock -T
nVidia Geforce 8800GT
=> GPU temperature: 68C
=> Board temperature: 54C
user@host:~/src/nvclock/nvclock/src$ ./nvclock -T
nVidia Geforce 8800GT
=> GPU temperature: 37C

I just got a 9500GT for another PC. If I notice anything odd with that I'll report it. Thanks for the good work on nvclock so far.

[Thunderbird]

It is likely a rounding difference. The sensor outputs in more than 8 bits and right now I'm showing just the part in front of the dot/comma. I could also show the extra fraction but it isn't that important, you could say it is noise.

btw: this card has no fan - but I can change fanspeed :-D
