this was the first time I tried reclocking. When the GPU is idle,
reclocking is successful and the same WebGL app runs a lot smoother.
BTW, the machine I tried was a Zotac ZBOX MiniPC ID41 series.
I also have a question related to reclocking on other chips.
Zotac ZBOX ID84 series:
# lspci -s 02:00.0
02:00.0 VGA compatible controller: NVIDIA Corporation GF119M [GeForce GT 520M] (rev a1)
# lspci -s 02:00.0 -n
02:00.0 0300: 10de:1050 (rev a1)
Zotac ZBOX ID86 series:
# lspci -s 02:00.0
02:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1)
# lspci -s 02:00.0 -n
02:00.0 0300: 10de:104a (rev a1)
All three boxes are out of production now, but we're using about
20,000 (really, about twenty thousand) in total of them at my company.
Nouveau supports them just fine, the main application is video decoding/playing
and it works very well for the supported codecs reported via vdpauinfo.
Is there a known roadmap to support reclocking on these latter two?
Thanks,
