Re: Mining ethereum with NVIDIA 9xx cards in Windows 10 with latest drivers
Benether, since you are already using claymore miner, did you also try dual mining? And did you play with -dcri values for balancing eth/dual coin
Ofc in case that overclocking core on 970 gives adequate ethash boost, that means that ethash algo uses all gpu power, in that case dual mining will not be of much use

Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.8 (Windows/Linux)
Have you tried ZEC? Because from what you are talking, since they aren't balanced (memory/core) like amd and lower nvidia cards, would be interesting to test them on a mining process that requires both memory and core power. Using higher than 8 intensity would be also nice (dunno if this is possible).
Unfortunately I haven't tried ZEC, but according to WhatToMine, gtx1080 should give around 450 H/s for ZEC. It should be profitable to mine it solo, just I don't know of any ZEC dual miner to experiment with
Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.8 (Windows/Linux)
IMPRESSIVE--
Thanks for the post! NVidia cards work well with higher "-dcri" values. But, Maxwell (900 series) cards are likely to reach maximum performance at a much lower "-dcri" value than 500. A setting of "-dcri 75" is a good place to start for Maxwell cards.
You're welcome
Radeon 4xx and 5xx cards, 1060 and 1070 cards all have core power more "in tune" with their GDDR5 memory speeds for ETH mining, so there is not much core power headroom left for second coin in dual mining mode. But, 1080 have plenty of core power left so the second coin can be mined very fast
Full -dcri 500 can be utilised and probably more Somebody with a 1080Ti card could do a few test and see what is happening with -dcri value in ETH + LBRY dual mode. Chances are that card could also mine second coin very fast
Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.8 (Windows/Linux)
Hello, this is a question for Mr. Claymore
My rig has 4 gtx1080 cards (radeons and 1070s are very hard to find or overpriced)
If I solo mine LBRY (with ccminer) it gives 380 MH/s lbry per card (a bit overclocked)
If I solo mine ETH, it gives 22.5 MH/s ethash per card (pity there is no way to mod memory straps on Pascal, at least that I know of)
This is where the things get interesting for 1080 cards:
If I run dual mining ETH + LBRY, with default -dcri settings (a low one) it gives full ETH hashrate and very low LBRY hasrate.
But when I start increasing -dcri, the ETH hashrate is still goings strong (minimal losses), but LBRY hashrate has a steady increase.
The max -dcri value Clayrmore Dual Miner allows me to set is 500: at that value, ETH hashrate is STILL STRONG and LBRY hasrate went up to almost 55% of full solo mining hashrate.
So, with -dcri 500, Claymore Dual Miner 9.7 gives 19 MH/s ETH hashrate + 205 MH/s LBRY hashrate
Calculated as a percentage of full solo mining, it is something like 85% of full ETH + 54% of the full LBRY at the same time
That is a great result!
It seems that if -dcri could go above 500, the LBRY hashrate would still increse, and hopefully ETH hashrate would decline only a bit, until the slow declining limit is reached. I want to know what is the limit
Gtx1080 cards have very strong processing power, but gddr5x memory is just not good for ethash algo. Lbry algo really relies moslty on processing power, so when doing solo LBRY mining on a gtx1080 card, you can downclock memory and hash would stay the same. Ethash relies on memory transfer, so when doing solo ETH mining on a gtx1080 card you can downclock the core waaay down and decrease power limit alot and the card would still give 22 MH/s. With dual mining, both core and the memory should be fully utilized.
Soooooooo... is it profitable to mine on -dcri 500? Sadly, it is no more profitable than mining solo LBRY. 19 MH/s ETH is similar to 180 MH/s LBRY or just below in terms of profits right now. Ofc, dual mining this way certanly won't hurt, but it is just not more profitable than simple solo LBRY.
Question for Mr. Claymore is: Can -dcri be set on more than 500 or can you make a test build with limit unlocked so we can try it?
