hello

I know you prolly come across this once before.. im having an odd issue.. I have multiple computers running several 7970 each.. What im doing is using windows remote desktop to swap between the different rigs.. What is weird is if i start ethminer within remote desktop it will only see one card, I then have to reboot computer and hook a monitor up to it and load ethminer from that console.> Have any of you seen this or had this happen.. seems their is an odd glitch if i try to run ethminer thru remote desktop. All computer running win 10 pro.

Best Regards

Install VNC on them. Don't use Remote Desktop

Thanks so much.. Ill get on that now and see what i come up with.. I really appreciate that.

I have a 7990 doing 47Mh/s at 1000/1500 and 1.075v
And a 7950 doing 19Mh/s at 1100/1500 if I recall correctly.

Your 95Mh/s for 1x7990 and 2x7950 Mh seems very good.

7990 doing 47mhs is good, my 7990 works 1050/1600 with slightly better hashrate.
7950 1100/1500 should definetly make more then 19mhs. Proper hashrate is 22-23.
Check your rig or miner settings.
Also keep in mind that hashrate data for eth are very approximate ...

I just increased my hashing power for ether by an aditionali 10 mhs

How did you do that? By increasing the memory frequency or the core frequency or an additional card?

I don't know why you guys are comparing power when clearly ETH is so profitable that power shouldn't be an issue currently.

You are right, it isn't issue anymore. But if someone suddenly finds a way to cut power costs 30-40% without losing performance on 18 months old platform...

Hmm not sure how this statement makes sense. Unless youre a professional miner with a large warehouse you have a hard limit on how many MB/GPU combos you can install.

say you were to invest 5k for instance you could buy
33 ($150each) R7 370s that produce 16mhs each for total of 528 mhs drawing 5k or so watts.
15($330 each) 970s that produce 22mhs each for 330 mhs drawing 2k or so watts
15($330 each) r9 390s that produce 28.5 mhs for 427.5 mhs drawing 3600-4000 watts

I dont list the 280s and 280x and 7 series since you can only find used ones now.

most folks have a finite amount of space and power i.e 200AMP service so if you planed to go big you could fit in far more 970s than the AMD cards since you use far less power.

For the normal small miner the 970s seems to be the way to go but if you're a professional miner with lots of space and amperage the 390s seem to be the sweet spot and they are readily available.

Normal small miner should go 970 way, power efficient and really good 1080p gaming card. Easy to sell.

About that power statement,

I can mine ETH with 5 x 970 from 83MH@600W to 110MH@1000W.

Thats a really bad hashrate for 5 x 970s and the power use seems low as well.

I get 80 mhs with 2 good and 2 crappy 970s ( EVGA scs ) Total power use for the rig is 720 watt

what version of ethminer are you using and what OS ?

I tried to show how much you can save power with these cards.

I am about to sell one good 970, did some coil whine tests with that rig.

4690K + 8 GB + gigabyte gaming 5 + 2xstrix 970. 285-430Watts from the wall Grin

I mine eth with 2x7950 and 1x7990.
95mh@~850w
Voltage 1.05 makes wonders ))
And dirty cheap ... was to buy ... before eth crazy )))

How much does each card make?

I have a 7990 doing 47Mh/s at 1000/1500 and 1.075v
And a 7950 doing 19Mh/s at 1100/1500 if I recall correctly.

Your 95Mh/s for 1x7990 and 2x7950 Mh seems very good.

I have 4x7990 undervoltaged to 0.95 V, 850/1250MHz. It does 156MH/s with 1320W from the wall, So that is 8.46W/MH/s.

you can do better with six 970 = 1020w for 132 megahash, this is 7.7w/mh, and this is also a more cheaper rig

4x7990 = £1100. 6x970 = £1500. So it is more expensive to use the 970. Maybe the 970 will hold value better.

If you are looking to sell it later yes because it will play newer games and that is one of the secondary markets for these things on eBay other than miners.

I wondering if the 7970 can be used in the GPU mining in the future. It has 3GB memory and can handle a lot of things.

are you sure about the 200watt per card for 22 only, i can run one at nearly 22 but it is sitting much lower in consumption, around 170w max, so with six gpu this is 1kw not with 5 only, like in your case

In everyday use it takes ~920W from the wall, mining proxy reports 108MH for 24h hashrate. It isn't pure mining rig, ~100W load all the time. I was just testing max power usage.

If power costs for mining 1 ETH are ~50 cents it is not worth it to save power. That was my point.

Where do you buy your 970s ?? what price and what model ?
