The correction values which I use right now for the internal sensor aren't correct on geforce8/9 cards. These values come from the bios but I might not using them correctly or don't have all values.

In short nvclock reads a 'raw' temperature and then has to convert it into the real temperature using something like: temperature = raw_temperate * slope + offset + correction. It would be interesting to know what rivatuner shows for some cards. In its diagnostics report it shows the values it uses.

**KeithB** · 16 December 2008, 04:30 PM

Slightly behind the curve, but I'm currently arguing with a 9800M GTS that nvclock can probably help me with so count that in. Main thing for me is smartdimmer control if it's still an option with these cards.

Let me know what you need.

**Thunderbird** · 16 December 2008, 04:35 PM

Latest cvs should improve temperature readings on a bunch of cards which use an internal sensor. All should work well now except for G80/G92.

For smartdimmer show me the output of nvclock -D on latest cvs.

-D output (had to use -f too) from a 2 hour old CVS build below. For reference (if it matters), the Nvidia drivers are 180.11.

Please retry using the latest cvs. It unlocks this feature (although I can't say if really all those laptops have it) on laptops from HP, Sony, Samsung and Zepto. Also show an updated nvclock -D output if nvclock says your laptop isn't supported. Note smartdimmer might have no effect on your laptop.

How latest is latest? The build that generated that output was pulled from the CVS server about 2 hours ago. The PCI ID is:

Code:

keith@X70MV:~$ lspci -vv | grep -i nvi
01:00.0 VGA compatible controller: nVidia Corporation Device 0628 (rev a1)
	Kernel driver in use: nvidia
	Kernel modules: nvidiafb, nvidia

The laptop itself is made by a UK company called Novatech - it's the X70 based on a standard Clevo chassis.

**Thunderbird** · 16 December 2008, 07:08 PM

AT this point the changes have been made 76 minutes ago and I added some other fix as my detection was broken about 16 minutes ago

**KeithB** · 16 December 2008, 07:18 PM

Now that's just showing off

I need to hit the sack now otherwise I'll not get into work in time tomorrow - will post the post-rebuild results as soon as i can tomorrow though.

Edit:Nevermind - I did the rebuild now - although the output difference was minimal. Command output for a -D, -i, -f -i and -f -D included below.

Code:

keith@X70MV:~/temp$ /usr/local/bin/nvclock -D
It seems your card isn't officialy supported in NVClock yet.
The reason can be that your card is too new.
If you want to try it anyhow [DANGEROUS], use the option -f to force the setting(s).
NVClock will then assume your card is a 'normal', it might be dangerous on other cards.
Also please email the author the pci_id of the card for further investigation.
[Get that value using the -i option].

The easiest way to test if smartdimmer works for you is to edit src/backend/nvreg.h. For instance edit 'PCI_VENDOR_ID_ZEPTO'. Change its value from 0x1a46 to 0x1558. Then recompile nvclock and then try.

**KeithB** · 17 December 2008, 03:03 PM

That tweak to the source results in complaints about it only supporting the 8x00 or less series.

Code:

Error!
Smartdimmer is only supported on certain (HP/Samsung/Sony/Zepto) laptops using a Geforce 6200/7x00Go/8x00Go. If you want support on your laptop contact the author.

I'll do a bit more digging around and see what I can find that might help.
