GTX 280 GPU2 not underclocking
Title says most of it.
I have 2 EVGA GTX 280 ssc's. When they are idle, one under clocks itself, and one does not. I would like it to also under clock to lower temps and power usage.
I have done some googleing and not much comes up, mostly people trying to stop it from downclocking. So no luck there :(
Anyone have any ideas?
does this happen with sli enabled, or both?
This is currently happening with SLI enabled, Ill disable it and edit this post with and answer for you.
With SLI OFF - GPU2 drops down to the normal idle under clock, and GPU 1 now sits just above the idle under clock.
So is there a way to fix this while keeping SLI on?
Been down this road a few times....its always Driver related....try a previous Driver that they downclocked properly with......which Driver are you presently using?
I am currently using the newest beta drivers.
go back to the nearest whql.
258.96 or as I said, the last version which the Cards downclocked properly on...during the 19x.xx Driver release, I stuck to my 18x.xx Drivers as none of those newer Drivers would downclock my 280's properly......btw, my 480's are downclocking fine on the 260.xx Beta's....
I have dropped back down to 258.96 and the problem still persists in SLI mode. :(
I guess Ill just have to live with it.
^^^^ 1 Driver change may not solve it.....don't give up...try a few of the previous Drivers until you find one that it functions correctly......was 258.96 working (downclocking) your Cards properly? Are you doing a "clean install"..?....as in Driver Sweeper, CCleaner etc etc....also uninstall and re-install Precison (if your using it)..as in clean install Precision after clean install of Drivers. Trust me....I have been down this road...
