Decred DCR Mining Pool Profitability

Hi People, After testing a few of Claymore's releases, I have found out that some variables are better than other, with some giving an increase in profit while others offering some potential profit in the future, if these coins are kept 'in the vault'. All tests have been documented and I want to share these results with you, in the following lines: Claymore's Dual Ethereum+Decred AMD GPU Miner Power Consumption The following test shows the approximate power consumption (from wall) for each of 5 steps in the Claymore’s Dual Ethereum+Decred Miner using Catalyst 15.12. This test only approximates the power usage of 1 rig and may not be a valid way of calculating your exact power consumption, due to component variables, Volt input (test was made on 230V line), overclock and component life. In order to demonstrate how this mining test will perform, all clock/core speeds are set to stock, only temperatures and power consumption will be monitored during this test. Nice summary.

You need to test other cards, I concur with your results for 280s and 280x cards but on 390s and higer cards dcred around 40 provides the best 'bang for you buck' I agree with you though anything over dcred 40 is just a waste of power and needless stress onthe GPU since it reduces eth profits. My rule of thumb is run the miner with no dcred i.e 0 to see the max eth hashrate then slower raise the dcred rate until the eth hashrate drops then stop.

Dcr.suprnova.cc - Suprnova's Decred Pool. [2017-08-12 17:49:29] Stratum connection failed: Failed to connect to dcr.suprnova.cc port 3252: Timed out [2017-08-12 17:49:29]. I currently dual mine eth with sia. But want to change 1-2 rigs to decred cause I´ve heard it´s more profitable. I´m currently.

Usually dcred 30 on slower cards and 40 on faster beefey cards like 390, 290x and Nanos. Not sure what your settings are but i average around around 37,623,087 khs on the pool with my 1900ghs or so of amd hash. I gave the 4.1 version a go. First of all want to say it's a huge improvement over the old version. Second of all the same issues are valid. In 20 degree ambient/outside temperature using the good old 0.941 ethminer the 2x7950 I have left in my case are running at 74 and 72 degrees with some headroom on the fans.

36MHS effective on the pool. Using the dual miner gpu 1 goes up to 82-83 with fan at 100% Gpu 2 sits around 76 with higher fan speed.

ETH hash rate is exactly the same for both programs. Yet dual miner is less effective in the pool. Decred rate is much lower than expected at 555mhs should give me over 0.3 DCR a day but with dual miner I can see only 0.2 a day. Again it looks great on paper but the numbers in the pool don't lie.

Something does not add up here. Considering higher temps and higher power draw it's just not worth it in my opinion. I see better results having the room to overclock using stock ethminer. The only true thing is that dual miner reduces the amount of rejects to the pool. (no improvement since the effective hash rate is lower anyway).

** To anyone who went for the slightly higher profits with Dual Miner. (especially if you are based on second hand cards) Minig is a hell of a long marathon. It doesn't matter who runs the fastest for a month or two. It matters who can run for 2 years. It's not about the series of cards. It's about the engineering desing of the card.

Read model/variant created by the manufacturer. I just did some research and test on this. Verge XVG Miner Hosting Canada. Powercolor 7950 sits around 17.3MHS and it's pretty much locked at 925/1250mhz BUT it's got high quality ASIC parts and 2x6pin.

Which means it's very efficient with the power it gets. - this one works well with dcri change and hashes 345MHS DCR at dcri 40 - Gigabyte 7950 rev2 OC sits around 19.5MHS and you can clock it like crazy. BUT it's got low quality ASIC parts and 1x8pin + 1x6pin. Which means it's got a lot of leakage, it's inefficient and considering the 8pin it could peak up to 300W on power draw up there with 7970 280x or 290.

- this one doesn't work well with dcri change and I will be selling it anyway. To wrap it up. Dual Miner uses extra chips of the card producing more heat. - If the card is of high quality + stable voltage it will work well. - If the card is of low quality with high OC capabilities it may work well but the Power Draw and Heat will go through the roof. Looks like Dual Miner will work best on cards which are maxing out the power draw for their physical/electrical capabilites. Like 7950 with 2x6pin R9 290x with 8pin+6pin and 7990 with 2x8pin The closer your gpu TDP is to the max capabilities of the electrical PIN connections the less power draw/heat increase you will see and dcri will give you highest benefit by accessing the unsued chips of the card.

I've been reading from the shadow since I had some projects to finish and less time to chat. Thank you for your interest in this thread and for sharing your thoughts with others! I really endorse your option since miners should share their options where others share theirs and help the comunity find the best efficiency for their spent bucks! Yes, from what my rigs are showing, 270 are pretty slow and yeld 16/13mhs eth/dual while dcr is at around 220mhs. Asus strix 380 is still a slow card but it can be maxed to 1100core clock and yeld 19-20 eth in dual mode and 400mhs with -dcri 40 On these cards I can't measure the power draw since I'm on my last risers and can't swap the PSU + risers cost like hell ($9).

Anyway, I see that everyone is having the rejected shares issue with dcr (10-20%) and I will try to fix this with a stratum proxy. Btw, any links to a stratum that gave good results and not break your brain with installers? Thanks guys and happy mining!!!

Click to expand.The problem at the moment is actually not the DCR price. It is high enough if the DCR network would be at 3-4TH/s, i.e. If only people interested in DCR would mine it, as it was initially. Because these people would sell only part of the mined coins and hold most of them or use them for PoS. However appr. Three weeks ago Claymore published his dual ETH+DCR miner. Since both coins use algos which are somewhat complementary on hardware usage, this miner is mining ETH at full speed and additionally mines a lot of DCR at the same time.

Since ETH difficulty goes up and coin price goes down, ETH miners of which most have no interest in DCR whatsoever use this dual miner now to mine DCR at the same time at no additional cost and therfore get compensated for the decreasing ETH profitability. As most of them will just sell the mined DCR right away, the DCR supply is now higher than the demand. There were always less than 50k DCR for sale on Bittrex.

Last time I checked there were 60k. That obviously doesn't help the price. DCR network is now mostly at 7-8TH/s. Half of this hashrate arrived recently and probably consists entirely of ETH folks dual-mining DCR at no cost. When you take a look at the DCR pools, you will now often see very long and cryptic names for miners starting with 0x. As far as I know these are ETH addresses.

Mining ETH is still much more profitable than mining DCR and now even more so since DCR profitability dropped after many ETH folks co-mine it at no cost and then dump it, pushing the price even lower. I would therefore suggest DCR miners to use the Claymore dual miner as well and mine ETH at full speed. Profits will be higher than mining only DCR. And at the same time it mines DCR as well at no additional cost.

The big slaughter for DCR PoW mining will come later this year or next year, if ETH will really switch to PoS and abandon PoW (they think it will work.). If my back of the envelope estimate is right the ETH network has now the equivalent of 80,000 $500 GPUs hashing. If all those get jobless and turn their attention to DCR, we will see DCR network go to 200TH/s. Of course only if DCR price will return at least some profit at that huge to be expected difficulty. Yeah it's kind of hard to calculate an accurate ROI since we're still in the early days.
