Hey guys, I'm new to the forums, was wondering if anyone could point me in right directions. I had couple questions. I've been gaming on this machine for few years now, but recently for few week I have been researching on cryptocurrency mining. I have decided to give it a try, I started about a week ago, still running, was wondering if these are safe numbers to run 24/7 on this machine without frying anything, from my research it seems to be safe, I just wanted to verify with some experts on here.
PC :
MSI m7 z270
EVGA Supernova 650 Gold Power Supply
i7 Kaby Lake 7700k with Corsair h100i v2 Liquid Cooler
NZXT s340 tower Case
Corsair Vengeance 2x16 DDR Ram
EVGA GTX 1080SC Video Card
960 Evo nmve ssd m.2 drive
Samsung ssd 850 evo
 
First couple days I ran nicehash but then I decided to experiment with phoenix/minerstat and I seem to be getting better results.  I'm attaching a flikr link to a photo with some current stats, after 8 hours of run time.
I was wondering are these safe numbers. Also I have a evga FE RTX 3080 on the way, would it be advised to run them together for more mh/s, or just running the 3080 alone would be more efficient and sell the 1080sc ? If I decide to run them together will I need to
upgrade my power supply ? I greatly appreciate any help and input. Thank You
 
Edit;
Seems I need to be a member for 5 days to post a photo :/ sorry

First off I would get back on NiceHash and use their Excavator miner. There are no fees with that miner and the numbers are just as good if not better than Phoenix miner. Also if you have a PayPal account, which you should, get a Coinbase account as Nicehash will transfer your Bitcoin to Coinbase with no fees, sell your Bitcoin and Coinbase will send the money to your PayPal account with zero fees and PayPal will send the money to your bank account with zero fees.
 
Now as for your GTX 1080, follow the advice on this video. You should be able to run both cards with your PSU, just keep an eye on the cards temp as the case you have doesn't look like it has great air flow to me.
 

thanks for your reply I will check that video out shortly, I curently use coinomi wallet directly from phoenix , here are my settings and stats I use EVGA Precision x1 software

Power 65%
Temp 75c
Gpu clock offet +150
Mem clock offset +700
The temperature never goes above 51C

I get 34.5-35.3 MH/s

kram36
34.5-35.3 MH/s is pretty good, but you're losing a lot in fees. Mining pool fee, transfer to your wallet fee, transfer from your wallet to wherever you sell it fee, it all adds up.
 
2 cards mining in on case will knock your temps up if you don't have good air flow.
 
You have a great motherboard to spread those cards out for better air flow between the cards, but your case won't allow it.

I see I just liked the miterstat dashboard alot, ok, ill switch back to nicehash then, and I will look into getin a full tower case, do you know if that EVGA 650 gold will be enough for the 2 cards ? or ill need atleast a 850, thank you for your reply

I think you will be fine with the PSU you have, but a 750W PSU is more then you would need.
 
I just picked up this case for $104.99 shipped, but I see Newegg raised the price on it.
 
https://www.newegg.com/p/N82E16811147053?Item=N82E16811147053
 
It has 10 pci expansion slots. You could put one card in the top pci-c slot and the other card in the bottom pci-e slot with this case. Don't worry about the pci-e bus speed of the bottom slot as it doesn't matter with mining.
 
I would do a price alert on the case for $104.99 if you're interested in it. It's a solid well built case.

ohhh I like that case , might order it lol , im using the DaggerHashimoto Phoenix, it barelly drops below 37, very solid, but I just tried excavator and its even faster 37.73-38.4 wow, although the power went to 164 Watts on there from 138, not sure how accurate that is

thank you, I will keep n eye out for it for sure, by the way, where do you read about pool fees?

thank you, I will keep n eye out for it for sure, by the way, where do you read about pool fees?

If you read at the pool's TOS, it will tell you their pool fee. What pool where you mining at? If you meant miner fee, Phoenix miner tells you when it starts up in big yellow letters "Warning: Dev Fee 2%". Excavator is NiceHash's proprietary low-level CUDA miner and has no devfee.
 

ahh got it thanks, I'm excited to see what the new card will do , but the bigger case is great idea for more air I dont know why I bought a small case at the time, even a mid would be tons better, also forgot to ask do you use your CPU option to mine under devices? looks like there is only 1 available (randomxmnero) and its seems very little benefits but I don't see any harm to tag it along I suppose, the memory offset clock is actually at 600 in the photo, i haven't applied 800, not sure if 800 would be safe

I don't mine on the CPU as I use low 35 watt processors. Intel processors don't mine real well anyways and RandomXmonero seems to be optimized for AMD Ryzen processors. You could give it a shot and see what your CPU does, but you need to know how much power the CPU is using and what you pay on $/kWh and put that into your NiceHash miner. I did a test run on my i9-10940X CPU @ 4.5GHz and I would lose 03₵ per day because my CPU eats a lot of power and that's not counting in the rest of the system's power usage, just the CPU lol.

I use NBMiner in Nicehash.  It has a 1% dev fee, but has enough of a higher hash rate than Excavator, for NBMiner to be more profitable for me.  Phoenix has a slightly higher hash rate than NBMiner, but Phoenix has a 2% dev fee, which again makes NBMiner more profitable for me.
 
My most profitable is 1822 MHz core at 0.812 volts.  And +100 MHz memory which is 5103 MHz, but ends up at 4617 MHz while mining (due to the NVIDIA derating for compute applications).  I have NBMiner's built-in Ethlargement set to level 6.  I see no difference between NBMiner's built-in ethlargement versus the not-built-in ethlargement in Phoenix miner, performance-wise.  Having it built-in is another plus for NBMiner in my opinion.
 
Lastly, Phoenix miner has a way higher stale rate than NBMiner for me, so there is no question which one is better, in my experience.
 
My DaggerHashimoto MH/s is 33.8, which is low, but that is where I am most profitable.  If I increase core or memory, my MH/s goes up, but my power usage goes up by more; enough to make it not worth it.  Between 4617 MHz memory (actual memory speed while mining) versus 50xx MHZ memory (actual memory speed while mining), I see an almost immeasurable difference in hash rate, so I chose the lower since it uses slightly less power and is slightly more profitable for me.
 
My most profitable settings (1822 MHz core at 0.812 volts, 4617 MHz memory while mining, and 33.8 MH/s) nets 4.64 Watts per MH/s actual total system power draw at the outlet.  My card is power modded, so the values reported by NVIDIA are completely worthless to me; and I can't use the NVIDIA or Nicehash power limit to limit the card (I have to use the frequency/voltage curve to do it while measuring wall outlet power draw). I can get up to 37.8 MH/s, but then I am up to 4.89 Watts per MH/s total system power draw at the outlet.
 

 
 
Just my 2 cents with a 1080.  Give it a try, if you like.  It's just another method to achieve the same result.
 
In my opinion, you should try limiting your memory and see if it really makes much of a difference with ethlargement at play.  You might see that ethlargement compensates well, and you end up more profitable by saving on power at lower memory frequencies.

thanks, im playin around with the settings, i lowered my mem clock to +100 and lowered core clock +85 and speeds seems to be the same and watage went little lower so i asume its better, but the temo went up from 51 to 56c wich doesnt make sense, still learning

 
Hum, looking at your CPU hash rate and plugging in my power cost and your CPU TDP, you are losing 01₵ a day mining on your CPU.
 
Also your GPU power usage is high IMO.
 
Open up NiceHash miner and go to the Setting button.
 

Then go to the Advanced section and change these two settings
 

 
Stop the NiceHash miner, right click on the desktop icon and run as administrator and start mining, but don't apply any settings to it with Precision XOC yet.
 
Now go to your mining page in your web browser and change the power setting to low.
 

Your hash rate will probably drop, but open up Precision XOC and reapply your settings and the hashrate will go right back up to your current hash rate and hopefully you are using less power.

I habe disablendevice power mode setting checked and also nvidia p0 state checked as well

Make sure you run as administrator and also do the low power setting on the web browser page. Then apply your Precision XOC setting. Then post what your power usage is.

 for some reason I get better MH when I underclock the core to -400 now with new settings but the power went down to 140ish which is a positive thing I asume , still learning lol here is updated shot
 
 

kram36
You can't get the MH/s back up to 37 with the power at 144?
 
Also do you know what your $/kWh cost is?

i bumped the power from +80 to + 90 and MH seems to be floating around same 35.5 power 143 but ill give it 10-15 min or so atleast to see

0.131229 kwh

You can enter your cost per KWh in Nicehash and make it display net profit.  That will give you a better idea of where you are most profitable.  Otherwise, you will be fooled into thinking that more MH/s is more profitable because Nicehash will assume that your electricity is free.
 

 
That's why I am running mine down at only 33.8 MH/s.  It is more profitable for me down there.
 
Your profitability looks way higher than mine, because your profitability is not taking into account the cost of your electricity.  Once you enter your actual electricity cost, you will get a realistic profitability and have a better idea of what is cost-effective.
 
My profitability displayed is not correct either, because my card is power modded and NVIDIA is not able to accurately measure my card's power consumption.  When it reads "20" watts, it's more like 120 watts.  I am not actually that profitable either, but I can still use it for comparison purposes when I make changes.  I use a kill-a-watt meter on the outlet to determine my actual profitability.
 
But since your card is not modified, you don't have to worry about my troubles, and you should be using net profitability in Nicehash when making decisions.
