Apologies if I've missed this somewhere in the thread but I've noticed an interesting behaviour of my 1070 GTX. Basically I normally get around 272MH/s with 1.8.2 but have noticed sometimes it has been dipping to around 225MH/s and I couldn't figure out why. Anyway I did a bit a digging and noticed if the Memory Usage on the GPU (monitored with GPU-Z) drops below around 512MB the GPU Core Clock drops down to a default speed of around 1531MHz. If I open a web browser or something which increases the GPU memory usage it pushes up the GPU core clock up to max and I get 272MH/s again.

Anybody else seen this? I'm using the latest NVIDIA drivers 372.90

I've investigated this a little more and it may not be memory but something to do with the driver and how it turns on the GPU boost. As a test I opened a browser (Edge) and the clock was at 1531MHz and the Memory Load 0.57GB. Load up this site to type this reply and the clock was still at 1531MHz. I then opened a new tab and simply doing this pushes the core clock to 1873MHz, exactly the same Memory Load. Closing the new tab the Clock drops to 1531MHz??? This is repeatable. I've a ton of things running the background but none of these make any difference. I tried a few other programs, playing a video with the built in Windows 10 player pushes it up to 1873MHz again but playing a video with VLC doesn't? Anyway to keep the core clock high I have to leave Edge open with two tabs, which isn't a problem but am interested why this is happening.

Run for a while now and it is stable with 69-72C temp range and the clock fluctuates between 1847.5Mhz and 1873MHz.
