I’ve just put together a small mining rig consisting of 2x ASUS 1080Ti Strix O11G, waiting for an upcoming offer before I buy and install another four cards. Now, before I built this rig, I tried mining on my desktop single GPU GTX 980.
On my regular desktop I experimented with overclocking, and I got to the understanding that just regular overclocking through MSI afterburner etc. wouldn’t get me what I wanted, namely increased speeds in P2 state. I’ve tried every possible tweak to make the GPU mine in P0, but I haven’t figured it out. In the Nvidia Profile Inspector, there was supposed to be a “disable P2 state” or something, but the closest I have is the “Power Management Mode”, which does nothing to the P-state.
So in order to overclock my old 980, I overclocked the GPU/memory in the P0 state first (using NVIDIA Inspector), and then I set the P2-state to the new boost speed to match the P0 speeds. I did all this manually and created some shortcuts on the desktop to quick-clock after restart.
Now, I had hoped to create something more automatic on my new 1080Ti-rig, and I’m not sure where to start. Firstly, I can’t seem to make sense of the clock speeds of my new cards out of the box. The clock speeds shown in the Nvidia Inspector doesn’t match with what ASUS claims as specs or what the boost speed is supposed to be (screenshot attached).
According to the ASUS website, my card has a base clock of 1569MHz and can boost to 1683MHz at default settings. During mining, the NVIDIA Inspector and GPU-Z claims that the core is running at 1923-1924MHz. This is while mining and is way above what it is supposed to be. Also, NV Inspector shows that my memory runs at 5505MHz (which should be correct as the mem frequency is double that at 10010MHz). GPU-Z, however shows my mem speed at 1251.5MHz (which could be just how GPU-Z presents the number, as it is 1/8 of 10010MHz).
Now, I’m a bit confused (to say the least) about how to overclock this correctly. Do I need to use NV Inspector? Is there an easier way of just increasing core/mem-speeds and auto-clock at startup (together with starting the miner).
I’m not really complaining about the hash speed out-of-the-box (720-730 sol/s on each card using EWBF miner v0.3.4b), but I would like to see what speeds I can get, even trying to make the cards draw a little less power (currently at 260-270W each).
Are there anybody out there that can shed some light on my problem and nudge me in the right direction? Or better yet, just tell me what I should do?
