syphear Posted October 23, 2015 Share Posted October 23, 2015 I have a problem with my GTX770m, the GPU clock does not change at all anymore and I think it might be a hardware fault. I have installed "Nvidia 770m - 80.06.51.00.0F 'OC edition' rev02" vbios and even when running 3Dmark 11 the clock will not change from 135MHz. (fault is also present with standard Dell GTX770m vbios driver. Any help on this would be appreciated. Quote Link to comment Share on other sites More sharing options...
CB400SF Posted November 16, 2015 Share Posted November 16, 2015 1) try power scheme setting of Windows to like 'ultra performance' or similar.2) check AC adapter on BIOS and if it says 'unknown' adapter, that is the problem. Quote Link to comment Share on other sites More sharing options...
