Learning Lesson:

I just came across an issue of one of my RIGs restarting every 7-20 minutes. 
After MANY hours of changing GPUs, Reloading Many Versions of Drivers, going to previous versions of programs and settings and switching out Risers; I swapped out the PSU and IT WORKED!

WOW what a chaotic situation.  Have an extra PSU around.

I got good prices on i5 6400ts. So all i5 and 1 i7

interesting, when i mined decred as 2nd i remember -decri being in the 40s but never benched beyond that iirc. ill probably swith to decred in a few days.

what cpus were you using? thought you ran mainly celerons  and a 6400t or two.

decred not pasc

the test above is using 6 rigs 5 with 2 gpus and 1 with 1 gpu.

all rigs normally use 4 cards.

the cards are

rx 470 4gb
rx 470 8gb
rx 480 8gb


no one is going to do this normally run a 6 card rig with 3 gpus and an i5
or in my case a 4 card rig with 2 gpus and an i5

normally these rigs all use 4 cards.

is that with pasc as the second coin?

with those settings on pasc as the second coin my 390 and 460 eth rate dropped about 50%, one 470 (samsung) dropped 60%, the hynix 470 dropped about 30%.

so the cards (or the coin) seem to be the difference as my cpu (G1840) is stronger than your panda cpu and my cpu topped out at 20% (so maybe 2% more cpu usage) anyway so power to spare in that . or perhaps its win7. your panda is 480Ms with 8 megs right?

EDIT lemme try my 3570k cpu and 390... i will amend this later as i have to set up the second coin on this box.

yeah but can you do -ethi 5 and -dcri 64  ?  

this where my eth falls off


at -ethi 5 and -dcri 60 my eth  does not fall off much at all

the intensity setting can influence the cpu usage but there should be no issues gpu mining with that cpu.

there have been occasional miner versions, including claymores cdm,  that used lots of cpu but its generally fixed next version.

there are tons of 4-6 gpu rigs dual mining with less cpu than that, celeron G1820 and G1840 are very common in miner rigs. i use a G1840 with 4 gpus and dual mine eth+pasc. cpu load is arount 18% with -ethi 12 and -dcri 20. using win7.

I have a quick question about CPUs.  Many of you know that I build my first 2 rigs with i7-6800k & i7-4790k CPUs.  In hindsight, this was probably overkill but since I work for Intel, I got both at half price, which was only about $100 more than buying a g32xx series outright from newegg or Amazon.  To my way of thinking anyway, the only real benefit to using these higher end CPUs is that they can mine XMR at a decent rate of about (300-350 Mh/s)... but, this is what I really want to question for the following reason...

For my 3rd rig, I have ordered a G3258 4 Pentium 3.20 GHz 3M Cache 2 Core CPU

https://smile.amazon.com/gp/product/B00KPRWAZQ/ref=oh_aui_detailpage_o03_s02?ie=UTF8&psc=1

I was under the assumption that the only big drawback with this vs an i7 is that I wont really be able to CPU mine XMR since that is dependent on # cores and corresponding MB of cache.

However, is there a chance that this could also negatively impact dual mining with either ETH + DCR or ETH + PASC?  Some of the comments I've seen lately have me a bit worried about this so wanting to get some feedback before building this new rig with that G3258 in it.

Thanks!

I think the same on some points,

but I thought there was some useful informations within the mining calculators as long as you only look how many eths you can mine in a small time (like a day)


Still wondering about the difference between reported and effective hashrate.. Most of my difference in profits is here...

ethpool calculator is worthless as are all calculators of all these pools.

The math explanation is hard to write in a post  but here goes.

ethpool bases your earnings for a month on a small time span


Estimated earnings
Based on your average hashrate as well as the average block time and difficulty of the Ethereum network over the last 24 hours.
Period-----   ETH--------------  USD-------BTC
Minute   Ξ0.00085--     $0.02   ฿0.0000
Hour     Ξ0.05112--     $0.97   ฿0.0008
Day           Ξ1.22693--     $23.17   ฿0.0182
Week   Ξ8.58852--     $162.19   ฿0.1273
Month   Ξ36.80795---     $695.09   ฿0.5455


for  instance ethpool uses 24 hours    simple far too small to be accurate.

in my case I should earn a block every 5 days or so.

but  the network diff  can get really high in the future.  and so can prices of the coin and prices of btc  not to mention  uncles  your down time in those 24 hours.

so to use 24 hours to project   a month is pretty much useless.


This is why  I dont pay much attention to the projections.
I have always had a good feel for math  and stats.

Every alt coin calculator has more factrs then a btc calculator.

And this is another reason I hate switching al-gore-rhythms   to pick the most profitable coins.  they are much like lemmings or sheeple programs.

but that is quite another bit of info.

I survive  the coin world by  a lot of math in my head hunch based moves.  I am good at it.  Like someone that sings well or plays a sport well. Kind of a natural.





-ethi 5  is easy on the cpu  you may not need it at all

blank is the same as -ethi 8


I use -ethi 5 on the pandaminer  and don't dual mine.  that unit has 8 gpus and a weak welded in cpu  it sometimes crashs at -ethi 6 7 or 8

it gives me 231mh on max  a crash a day  and 225-227 on -ethi 5    0 crashes

now on my 4 card rigs  with only 2 cards in them and i5 cpus.


  -ethi 5 and -dcri 42     allows for  say 47mh   and a lot of decred hash   like 1000mh

-ethi 7 and -dcri 42         has yet to be tested.

Guys,

What is the benefit of using the "-ethi 5" setting. On my test rig, the effect is small to tiny.

TIA

In the meantime Phil , I have another question for you , and everybody mining Eth to pool.
With my many test, I confirm your choice to go Ethpool , it seems to be the less unfair (compared to Dwarf, Ethermine and Nano)
But even with Ethpool , I'm still 10% less than expected profits from calculators.
Ethpool calculator is the closest to coinwarz, but my real profit are not here.

A big part of that loss seems to be from "effective hashrate" being always lower than "reported hashrate".


I would like to ask you if there are some settings that migh improve those numbers ? maybe I'm using wrong commands in my BATs.
What could be the cause of that difference ?
Do you see it too ?

in another hand, did you notice some lower real payout compared to their own ethpool calculator ? (the one you see in the payouts page)

wow nice, I missed it ...
Decred is explained now.

Still suspicious anyway to their other rates as discussed before. (eth)

EDIT : from what I can see, PASC mining could be currently more profitable than DCR when you compare you real NH earnings.

i posted it and it timed out


so back to nicehash and the high % numbers see screen shot

so  they say decred is 2492%   but not on based  decred  on  based on ltc!   

So according to what you say and what Citronick say , when the 2000%+ will be over, your earning will be 0.075 instead of 1.5 ?

I'm waiting your explainations for correct calculation cause for now I feel lost.

@ Citronick : from your example of 1eth earning would become 1.23 (with 23% over pps), that's here I'm suspicious : mining calculator doens't show 1.23 as expected mining profit through NH , but something under 1Eth.
And what I see in my real NH profit is generally under 1eth and not something like 1.23eth (sticking to the example)

sold off all the msi rx 470

I am building a rig for a friend  he wants to use asus.

http://www.provantage.com/asus-strixrx470o4gg~7ASUG00T.htm ------- good price

https://www.amazon.com/gp/product/B01N2V0AHI/ref=oh_aui_detailpage_o06_s00? ----  I got this for 67 bucks

http://www.ebay.com/itm/302219698895?  cpu  okay price i have used the seller


http://www.ebay.com/itm/272456808280? ----- i reviewed this on this site for   itop


http://www.ebay.com/itm/152390352179? -----  i have used this seller a few times






back to nicehash and the high % numbers see screen shot

maybe he just likes that "new card" smell. 

@phil i flashed that hynix 470 with 1500 straps and run at 1300/2100. nice ~20% increase with eth.

I thought you were selling 470s, Phil.

they are not accurate.

i am on a shitty edge tablet when i get to the pc i will show how to calculate correctly.


right now i am pushing 5600mh and earning about 1.50 usd a day with no loss on eth.

the power used may be  240 watts which cost me about 60 cents  so as far as i can tell i make 90 cents extra with decred.

if that lasts i would pay off 1 of the 11 cards in 200 days.

i also found a deal for some rx 470s  .  once they come on  monday i will post the new build.

i paid 170 new for asus rx 470  the white 2 fan model

Selling hash to buyers in Nicehash marketplace is different from mining ETH at ethpool or dwarfpool ETH pools.

Payrates should be determined by how much buyers are paying for the amount of hash available by sellers.

If you mining directly to ETH mining pools and say you get 1 ETH (assuming 100% luck at PPS mining).

In NH, the pay rate for your hash is 23% more than above at current time (1.23 ETH)

This is my understanding - correct me if I am wrong.

This is same method as DCR below.

See payrate table at https://www.nicehash.com/index.jsp

For selling ethash, 1 GHs = 0.0394 BTC (selling hash over 24 hours)

For selling DCR, 1 THs (or 1000GHs) = 0.2109 BTC (selling hash over 24 hours)

For DCR, if you have 4000 Mhs = 4Ghs.

4GHs / 1000GHs = 0.004 x 0.2109 = you will get 0.0008436 BTC which is very small

You need a more powerful rig, say a few hundred GHs to get a sizable BTC.

This is my understanding - correct me if I am wrong.
