this is my first patch on the list through git send-mail and I hope everything is set up right, sorry for the noise here, but I don't want to try with an empty mail :) as the subject already says, this patch fixes one of the more serious issues while reclocking gddr5 on kepler cards. It works for me and for a bunch of others I met on IRC. Karol Herbst (1): pll/gk104: fix PLL instability

Following a series of patches to improve nouveaus clock tree parsing. Reclocking these engines (all but memory) is pretty stable on the cards I've tested. Please review and merge when approved. These patches do not solve the problem that core/shader engine doesn't like to be clocked up too far without fb following, with visible corruption as a result. I suspect this problem is unrelated

Greetings, I am resending this as it doesn't appear in the archives and no one responded...maybe it got routed to /dev/null or something :-) I have asked this question the Scientific Linux mailing list (a few months ago) and got the suggestion I talk to the kernel guys. I pinged a kernel guy I know, and his suggestion was to ask the Nouveau list. So here I am. :-) I have had my work laptop
