Hi! May I ask what gpus you are referring to so I know you're seeing the nrs you're supposed to? The speed is about +15% if you're doing Vegas and set up mem timing yourself. We don't include automatic mem timings. If you're talking about Polaris gpus, you should see a power save instead. The reason is that the mem controller is already saturated, it doesn't matter how smart we try to be or how much we optimize the code. The only thing we end up doing is idling more waiting for mem requests, which in turn results in the lower power draw. You can either take that as-is, or you can increase the core clk to boost your hashrate somewhat, but that's only possible to a certain degree.
