ETH+RVN dual mining keeps hitting LHR blocks (LHR RTX 3060) #727

Open Alespic opened 2 years ago

I started mining ETH+RVN with the reccomended settings (that work wonders for me) but when I start, the miner keeps auto tuning and lowering my hashrates. I tried to turn off autotune, but my hashrates are way below the ones listed (1/3). Any solutions?

You might get better help in the discord, but here's the general troubleshooting recommendations:

1) Disable any overclocking/undervolting/etc, and see if it's stable. 2) Start with a lower lhr value (typically 30/31; though I get best results around 35 personally). 3) Make sure your fans are tuned up; I've noticed lhr sometimes kicks in if the memory gets too hot (over 102C).

If you're still having trouble, I again recommend asking in the Discord, and make sure to include make/model of card.

I've never Overclocked my GPU, but just in case, I used MSI afterburner to reset it. The memory temperature is just fine too. So, I've tried to run it without lhr autotune and using lhr value of 25, and still keeps detecting LHR. Lowers the hashrate, and resumes mining. Gets about 2 shares and then it repeats.

I couldn't find the discord server when I was searching for it, probably cause I was in a rush, so an invite link would be very much appreciated.

One suggestion: if you've been using t-rex with afterburner, stop. I used EVGA's Precision X1 until recently, and someone recommended I stop and my GPU is much more stable (OC software tends to interfere with t-rex's OC commands).

So, while I mine, should I turn off every other program? Also, I’ll make sure to use msi only to monitor the various things, and use the OC commands in the miner. I’ve asked support on the discord, and when I’ll get a working solution I’ll share it here and close the issue.

If your lhr-autotune keeps stepping down from 30 try lowering the power. You can limit power by EITHER the —PL flag or lower —Lock-cclock. If you power limit (PL) don’t lock the core and if you lock core frequency don’t put a power limit. My 3060 likes PL77 which is about 135-140w. The 3060ti likes a locked core at 1500mhz. Anything more will lock the cards and LHR will start steping down. I’m getting about ~18MH ETH and ~14MHs RVN as measured on the pool side 1 day average with 3060’s. LHR tune is set at 36. It fluxuates a lot of course, but thats more to do with luck and low hashrates. The averages look ok. I don’t use afterburner or other 3rd party clocking tools. GPU-Z is better for monitoring the card. Set the card clocks with t-rex. Take a paper and pen (or windows notepad) and write down results from different clocking attempts and give it time to see if it steps down. First you need to get it running at LHR 30 before trying for better hash rates, so start fairly low.
