1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.5 (Windows/Linux) on: June 19, 2017, 02:43:22 PM
Can anybody with a card which is not polaris (so no 460/70/80 no 560/570/580) run those 3 benchmarks?

-benchmark 130

then 140 and 150

I want to see the hashrate drop on non polaris card in the future.

Here you are... figures are obtained from 10 consequence result and take average

geforce GTX970 4GB running at ~80% TDP

120:   18.522 MH/s
130:   18.542 MH/s
140:   15.363 MH/s
150:   10.291 MH/s

Hi all,

I started mining with Claymore a few days ago and I am seeing an upsetting thing.
My GPU is an EVGA GTX 1080 FTW, watercooled, MSI Afterburner reports a RAM frequency of 5000 MHz, which is fine... but when mining with Claymore, the RAM frequency automatically drops to 4500 MHz. If I stop mining and start a game, the frequency goes back to 5000 - the 4500 MHz behavior only appears when mining using Claymore.

I suspect the driver somehow knows I am using Claymore and taxes me for that.
If I boost RAM frequency by +1000, it goes up from 4500 to 5500 MHz and the hash speed goes from 20.5 MH to over 25 MH - 25% boost - but this solution is clumsy, because whenever I stop mining I have to dial back the frequency boost, otherwise as soon as the GPU encounters any regular load, it tries to boost from 5000 to 6000 MHz and the memory can't handle it.

What should I do to keep mining with Claymore, but at correct RAM frequencies?

Hi, I don't have GTX1080 card, but I am currently mine on GTX970 which have similar issue. Try to use the NVSMI tools to raise the card power state from P2 to P0.
NVIDIA card stay in P2 power state when CUDA computing, memory speed will be limited in P2. Raise to P0 to unleash the full clock speed. Hope it will solve your problem.
