GPU OC settings for mining

[AnalogCanavity]

So I want to start mining cryptocurrency, though I don’t know which coin yet. And I was wondering what the optimal GPU OC settings there are. I currently have a GTX 1070 with a GREAT aftermarket cooler, so I’m not worried about overheating. The image below is my current stable OC, I’ve heard that you lower the core clock and decrease the power target and just increase the memory clock. Just wondering what you guys think.

 

Thanks

The higher the clock speed, the faster the mining, but the lower the efficiency of the card (so a lot more power for a little benefit). To profit the most, it's better to let the card run at its factory boost clock and undervolt it, rather than overclocking high.

So should I bother with memory clock at all, or should I do a test and see which works better.

Memory doesnt use much power so you can try overclocking that. Just make sure you monitor the power draw as shown by Asus GPU Tweak and hash rate, then figure out whether the increase in mining speed (if at all) is worth doing.

Interestingly enough, I found that when mining Eth on my V64, the clock speeds made no major difference to my hashrate. Whereas the speed of my VRAM made quite a bit of a difference.

So I ended up underclocking my gpu to improve its efficiency while still maintaining a hashrate of 25~35 mh

I think this is what I’ll do, I’ll lower my power target, put my voltage to plus 5. Keep my core clock at factory boost and just OC my memory.

It really depends on the type of crypto you are trying to mine. Ethash algorithm (Ethereum, ETC, Ubiq, Pirl etc.) depend a lot on memory. So OC-ing core clock doesn't really benefit the hashrate. Other algorithms, as i've noticed tend to depend more on core clock. I see you have a 1070 there. I'm now "playing" with a 1080Ti and am gonna do a benchmark on the most profitable algos for Nvidia GPUs. It is known that AMD best work with ethash algos. So, the question is, what algorithm are you trying to mine?

This is kind’ve weird, but for fun I currently want to mine garlicoin. And then move on to more profitable stuff after a week or 2.

Reading about it's algorithm (i didn't know it so far) - Scrypt-N, it appears to also be dependent to memory so you could try to start "OC" starting from 100% and lower the power limit untill you see a drop in hashrate. Stop there and slowly increse memory clocks (i do it by 100 on the 1080ti) until it doesn't grow anymore. At that point you could try to slowly increase the core clock a little and see if it does any hashrate increase. if it doesn't, either lower it or let it stock. Always check your temps so they don't go high. (keep them under 65C).

Ok, thanks!

Should I even OC my memory in increments, or should I just put it at max and lower my power target and slowly up my core clock.

too high might become unstable/crash (i'm now OC-ing my 1080ti and no crash at +1000 mem so far). Do as you want. it's your card
