NVClock, the open-source utility created by Roderick Colenbrander that allowed overclocking NVIDIA graphics cards under Linux long before
NVIDIA had introduced CoolBits has been through some tough times. NVClock could
mistakenly be considered dead.
NVClock 0.8 has been in development for several years now and it has yet to see a stable release. The last beta release of NVClock
occurred in January. Roderick has since moved on to helping out the
WINE project, but he still has interest in continuing work on NVClock though he lacks testers for those with the newer GeForce graphics cards.
On the Phoronix Forums, Roderick (a.k.a.
Thunderbird) said
he hopes to release a new version of NVClock but lacks the needed hardware or people to test out the NVClock code on their NVIDIA hardware.
If you are interested in helping out Roderick with either development work or testing out NVClock code,
place a message in this thread. He is mostly in need of testers that have access to
GeForce 8 and
GeForce 9 hardware.
While NVClock now uses CoolBits with the NV Extension for much of the legwork, it still has a low-level overclocking engine for some GPUs as well as fan control support for some graphics cards, faking a GeForce GPU as a Quadro ASIC, and various other features.
If you're looking to do more help in better enabling the open-source NVIDIA scene, the
Nouveau driver could always use testing especially on the newer graphics cards.
