can i add extra graphic card with my psu 650wat Aerocool

[the-morpher]

Hi

I want to add a second graphic card to my pc to mine ethereum.
I have already a pc with Gtx 1060 6gb sc that i use for mining and i want to add another gtx 1060 6gb.

So my question is about my psu, i have a Aero cool 650wat, how do i calculate how many graphic card i can use depending on my power.

My second question is about graphic card choice, is it ok to use another range like gtx 1070 ti ?
If so should one miner per graphic card or one to handle them  both ?

I use PhoenixMiner and Gminer (i alternate to test them xD)

Thank you in advance for your time to respond me.

1060 6gb when correctly clocked use under 110 watts at the wall.

so a 650 watt psu should do 3 1060 6gb gpu's if you clock them correctly.

[adaseb]

Yes the actual power wattage should be sufficient however will he have enough cables? What I found with most PSUs under 700Watts is that even though it can easily support 2 or 3 GPUs in power wattage there usually isn't enough PCIe cables to connect all the GPUs.

I am guessing this PSU only has 2 PCIe connectors. How many go into each GPU? Is it only 1 each? Then it should be enough however if it requires 2 PCIe for each GPU then obviously it won't work. I don't know why many manufacturers do this. They should include up to 4 PCIe connections.

[batsonxl]

No way that psu aerocool is crap, dont even try is my advise. Get proper psu.

[the-morpher]

Yeah i think so "Aero cool" is a crappy psu and though it does only have 1 connector of gpu, i did'nt make attention to that

adding this adapter would let you do a second 1060

clock the gpu to 80 watts or so. you should be fine.

Yes you can, even running 3gpus still doable but not good for long term health of your psu, best advice is using only 50% of psu capacity and thats the peak efficiency for psu

Hi Philip

Thank you for your response, yes it's same as the one in the link, then you encourage me to use a seconds graphic card, but i don't know about using 80wat for my gpu

Thank you Fmz, i think i am gonna do it, but what about cooling, is it enough if i left the left panel side of my pc open or should i use extra fan ?

thanx in advance

Back in 2014 I was cheap and instead of buying quality PSUs I would use these no name type of low quality PSUs which were like 450Watts max. I had tons of these because they generally were always included in a computer case and I never used them.

They only had 1 PCIe connector but you would easily make another PCIe connector if you rewired some of the other unused plugs. Keep in mind I used this to run an Antminer not power a GPU rig.

The issue was that the efficiency was crazy bad. It was like 65% or something. So if you are pulling 100 Watts from the wall, 35 Watts  is basically lost as heat and only 65 Watts went to power my Antminers.

They also usually only lasted 2 weeks and then would just die. I didn't even run them at 100% load, maybe 70% load and they just died shortly after. I think they are mostly for housewives who use their computer to browse facebook and pull less than 40 watts total from the PSU. But for mining... forget about it.

Is it in oc tool ?  i use msi afterburner and there is Core Voltage in % as 0 value
here is my oc config

First off let me give you credit for asking about your settings.


And oh my god wtf are you doing look at your power number 116%

give me a minute to fix this for you
power limit needs to be 70 not 116 this was a really bad setting




core clock  can be +0 like it is
core volts can be +0 like it is

power limit needs to be 70 not 116 this was a really bad setting
ram can be +600 to + 850 not + 1000
temp limit of 75c vs 92c

fan in the 60-80 range

microvolt is 1049 if you lower power setting to 70 I think that will self lower

the key is drop the  power limit down to 70
and drop the ram down to say 800

Hi Adaseb

Well yeah my pc was for gaming, but as games sucks today at least for me "prefer metal  gear solid 1000 times than the latest metal gear" i switch it to mining, and my first psu just died like in 2 years i think and i just buy another crappy psu -__-

Thank for your advice and experiance, i really appreciate that.

Yo Philip
Thank you for the time you gives me and for tips, but when i used the settings you told me i got a lower rate 22.44 mhs OMG

https://ibb.co/Bn2cDtP

but when i used mine, dude it rock like a hell, 26.2 Mhs

https://ibb.co/dbL1mCj

I have a Gtx 1060 6gb super clocked, already overclocked by factory, that why i can't increase core clock it crash my pc instantly
But what about Memory clock, i've seen in internet that we use the stable value and in fact 1000 is stable.
Power limit does unlock my gpu and can reach  26.2 otherwize it crash my pc cause not enough power i guess
Fan speed is on Auto most of time 50, if i do like you told me i need to fix it to a specifi value, but what happen if it need more fan, i tough fixing this value is bad thing is int it ?

About Power limit, i think you wanted to say that it's about efficiency and power comsumption right ? if it so well in reality i use a shared electricity with some dudes and it's not a big deal if it needs more power as long as it gives me more mhs but in fact i still pay the shared bill with the others but i think it's more profitable like that !!

waiting for your response.

so do everything the same but try 90% power.  see your hash rate then

I could give two fucks about watts per hash.

What matters is not killing  off gear.

no mining gpu should ever run at max power. it simply kills off the gear.

Hi

I reduced my setting as shown in picture

https://ibb.co/1q9dGft

And my hashrate has reduced in the miner but not in the stats in the pool ethermine.org

https://ibb.co/Hh4vyPd

there's event improvement in the Estimated Earnings 0.00151 ETH per day (before it was 0.00147 ETH with a higher hashrate)
So i don't understand the fact that before i use 26.5 mhs using agressive oc and result to less earning and now with low oc setting it tells me that i earn more, what's the point ?!!
Is its stales that are less happening ? cause i don't know which criteria should i take

I'll try reduce memory clock to 800 and see if there's some improovement maybe power limite to 90% regardless of hashrate and see

[philipma1957]

Well thanks for trying my advice out.

Most likely the gear was over clocked and tossing errors.

So you now help the card run at a more relaxed and error free speed.

Mining is so profitable right now that the only way to fuck up mining is to burn out the card.

My fear was you were going to do that with the 116% power setting.

 I have a rig with 3x 3080 cards.


Eth speed: 273.408 MH/s, shares: 904/1/0, time: 1:30

GPUs: 1: 91.497 MH/s (289) 2: 90.427 MH/s (295) 3: 91.483 MH/s (321)

GPU1: 64C 79% 222W, GPU2: 61C 77% 222W, GPU3: 53C 77% 222W

GPUs power: 665.3 W

note the 904/1/0 only 1 lost share as I make clocks gentler.

the cards do 91-93 each .  and just run

if your card can do a relaxed  25.5 and makes 1 of 500 errors

it is better than a stressed 26.5 and making 60 of 500 errors

more money  is made as 499/500 x 25.5 = 25.449 net on lower power

vs  440/500 x 26.5 = 23.32 net on higher power.


Plus killing the card is more likely at 116% power vs 100% power.

Same for ram.

 maybe 980 ram vs 1000
 maybe 900 ram vs 1000
 maybe 850 ram vs 1000
 maybe 800 ram vs 1000

great setting may be 95% power 950 ram or 90% power 900 ram

play with power

100% at ram of 1000,950,900,850,800.   so you  tested this at 1000 ram try the other rams

 then play with this one

 95% at ram of   "       "     "     "     "



 
then play with this one
 90% at ram of  "       "     "     "      "


then this one
 85% at ram of   "     "      "    "      " 


That is a lot of tests about 20 of them but even if you just do

100%. 1000 ram 950 ram 900 ram
 95%.  1000 ram 950 ram 900 ram


you will know you did some good testing. with 6 different settings

Hi dear Philip

Thank you, you just save my little card from being burned out as i used max limit of power.
I'll definitely try the settings you told me, good luck in your mining dude

Yeah I used to own a Kia Forte.  Near my house is an empty stretch of highway well paved very straight and a tiny bit down hill about 5.5 miles long. My Kia can do 105MPH on that road.

I did it once out of "I would like to know the cars limits".  But doing it day after day would kill the car.

[the-morpher]

haha yeah exactly what i tryed to do xD
My next goal is to do a cashout to see if it works then i can make a real rig cause it's not easy to do that where i live, all payement way is locked or don't accept my identity cause my country "Morocco" does not accept dealing with cryptocurrency (-__-) so must find a way to handle this.
After that i can chase left graphic cards still in market.
