1070/1070 TI Power Limit ETH Mining

[Helios45]

Hi everyone,

So my new rig is almost one month old and I've been mainly mining Equihash, Lyra2Ver2, NIST5 and Xevan

I was able to come up with the best OC settings for each algo after spending some time fine tuning

Today I decided I'd give Ethash a try using Claymore, my rig consists of 6x 1070's and one 1070 TI all Zotac mini, I was surprised to notice that power limit doesn't have any effect on the hashrate

I started my tests at stock settings, then OC'd memory to +750 on the TI and +650 on the 1070's then started lowering power limit from 100% all the way down to 65% by 5% increments and the hashrate wasn't affected at all by all the decreases while my wall power meter was keeping on going down

Is this a normal behavior when mining ETH while all the other algos I tested were being affected by power limit ?

Thanks

Ive currently got my 1070tis set to 700mem 200core and 70tdp

What's your hashrate ?

Currently 32.5 mh ETH and 160mh Pasc, dual mining. Whole rig of 5x1070ti is 710w

ETH mining on the GTX 1070 ti is a waste - they do a LOT better on equihash algorithm coins among other choices.

 The reason the TDP isn't having much effect is that the ethhash algorithm is VERY memory-limited, so dropping the core clock on MOST cards doesn't affect the hashrate for a long time as the memory can't FEED the core enough data to keep up with it.
 Even the R9 290/390 with their 512 bit memory bus can run the core at noticeably "lower" settings than on most coins and still hit max hashrate on ethhash.

Thanks for the explanation, I was just curious what kind of hash/s my rig would get, i don't have any plans mining ETH for now
