skeif95 Posted March 1, 2015 Share Posted March 1, 2015 Hi Guys,I really hope you can help,I've installed an 880m over my 7970m in my m17x R4. And as I wrote in the title it for some reason clocks down to 405MHz from more than 900 where it should be. It sometimes happens all the time which makes anything unplayable. Restarting occasionally solves it...I don't think it is caused by the heat since it hardly reaches 70° and sometimes it doesn't even occur that much.Also my seller gave me a new card after I reported this issue. So it is also not caused by the card.I tried multiple drivers, so I guess it is not a driver issue.And finally I changed the Nvidia setting from adaptive to prefer maximum performance.http://gpuz.techpowerup.com/15/01/12/fyn.png The load is almost at 100% but the Memory and core clock are downclocking all the time.Consequently the Benchmark results are very different depending on what the GPU decides...NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-3820QM Processor,Alienware M17xR4NVIDIA GeForce GTX 880M video card benchmark result - Intel Core i7-3820QM Processor,Alienware M17xR4So basically I have no idea why this happensI really hope you guys can help, Thanks in advance, skeif Quote Link to comment Share on other sites More sharing options...
Nitish.s22 Posted March 11, 2015 Share Posted March 11, 2015 I am getting the same problem with my M17X R4 and 880m.Can anyone help? Quote Link to comment Share on other sites More sharing options...
nebuz Posted March 14, 2015 Share Posted March 14, 2015 I saw something similar (I think) with my 770M. It only happened once though, and was when the machine was recovering (ish) from a slightly-too-high overclock. The driver eventually recovered, but afterwards it wouldn't go above 400MHz or so. Restarting the machine fixed it.As such, the issue could be related to too-high clocks or too-little voltage perhaps? Worth trying to underclock your card slightly and see if the issue still reoccurs? Quote Link to comment Share on other sites More sharing options...
skeif95 Posted March 15, 2015 Author Share Posted March 15, 2015 I underclocked it but it doesn't seem to prevent it from downclocking to 405MhZ, if it is likely to do so. Also I am using a 240 watt power supply which should be enough.Anyway, thank you for your response. Quote Link to comment Share on other sites More sharing options...
