Could be both, some people I know started with 1-3 GH within the last month and planning to add more. I stopped at 860 MH/s to wait for the 480s, I have 18 coming from Newegg tomorrow and 12 from B&H but don't know when.

You clowns will never ROI. Let me know when you are ready to dump your cards at a loss.

At least GPUs have a life after mining. What does one do with the S3 one has in one's basement?

LOL that's exactly where my S3s are sitting. In the storage area of my basement collecting dust.

Very true though even if mining eth becomes unprofitable there is still resale value to the video cards or perhaps another coin of the day may come along.

Currently I have 5 x MSI-R9-390 rig, doing around 145Mhs or 29.xx Mhs per card.

Afterburner settings at -100mV, 1015mhz and 1500mhz, core voltage, core clock and memory clock respectively.

The EVGA 1600w G2/Gold is pushing around 1270w to 1350w for the system ASrock H81-BTC, Celeron 1840 and 8GB RAM.

Initial plan was to use only 5 x GPU so that I can avoid using 2 x PSUs.

However, with the 1600 EVGA and undervolt settings, could I do the 6th card at 1450w (within the safe zone of 15-20%) of the PSU.

It will be prefered not to get the PSU worn out quickly if the rig pushes the wattage to maximum because even EVGA Gold is only about 90% efficiency.

Any advice to get the 6th card in without fear of the burning out the PSU?

Thanks

limit the power used by each card, downclock them a bit, you probably might fit them all in the 1600w, by losing some hash, the ratio should be the same in the end

I am experimenting on the underclocking for these 390s, and it may just go under 1600w but I was advised by fellow riggers that 1600-G2 on continuous power is only 90%-92% efficient, so pushing it too close to max will shorten PSU life.

you have one rail so zero issue on that balance rails comment.

the psu can give 1600 watts dc which is about 1800 watts at the plug.

a long review on it:

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=391

this shows it under a 1595 watt dc load which was 1792 watt ac at the wall

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=391

I believe you can do it but your wall plug if 120 volts needs to be a 20 amp dedicated circuit to do it longterm.

Thanks Philip for the guide.

My country uses 240v and I have 60amps to play with, any impact based on the above parameters on 220-240v specs?

it looks like all the cards from newegg are showing out of stock..
i got my invoice, so i should be good to go.

i paid for 3 day shipping an the 2.99 to speed up the processing. hopfully it shipped today and ill have it by friday or saturday.. but im guessing they were really busy so i wouldnt be upset if it was monday..

Monday is a holiday so probably Tuesday then.

wow they just changed my order to shipped.. so hopefully friday or saturday on my birthday Cheesy

Now the money is free, and so the people will be

doesnt matter really, it can do over 1600w. But keep it under. Mine has a 10 year warranty.

My 5X 390 uses about 1220 W using OCZ 1250W gold PSU. Frequency: 1100/1200MHz. VCore -110 to -130 mV. Vaux = -100 mV.

So you should do 6x390 on 1600 W without problem. But you need to allocate the power on each rail properly.

Thanks for the guide, could you elaborate some best practices for "allocate the power on each rail"?

woot.. stayed up all night long but they went on sale and i snagged 2 of them with expedited shipping..

http://www.newegg.com/Product/Product.aspx?Item=N82E16814150770

I am lucky, I live an hour away from their warehouse so I get delivery in 1 day or can pick up same day. Ordered 18 (Xfx, PowerColor and Sapphire 6 each) and they are already packaging them for shipping

I thought they limited it to two of each card per customer, but then again their limits are usually per order and you can just finish the order and then order another two of each. I wonder how much difficulty is going to go up once all these new cards are hashing away.

Newegg will cancel multiple orders from same account or same address. But if you pay with BTC and have friends, how many BTC you want to spend is the limit, right Wink

. Without 480s difficulty was rising .5TH-1TH every few days, it will skyrocket with the release of 480s that for sure.

Do you think the previous rise is caused by the AMD R9 390 or the nVidia 1070? The rise is too big for graphics cards.

Could be both, some people I know started with 1-3 GH within the last month and planning to add more. I stopped at 860 MH/s to wait for the 480s, I have 18 coming from Newegg tomorrow and 12 from B&H but don't know when.

I've tested 7990, 370, 380, 7950 and 7870.

For ethereum i find 2gb r7 370 cards are the best.

In wnidows I get 15 to 15.5 mh/s per r7-370.

In Ubuntu its 13.5 to 14 MH/s on a 6 card rig. - stock clocks 1030(gpu)/1400mhz (ram)

Cards run 60 to mid 70 C. I have 18 GPUs going on.

A 6 card rig will pull about 760-7800 watts at the wall with a decent gold PSU.

If overclocked to 1150/1500, power goes up to 850-900 watts/hour.

Hash rate in ubuntu then goes to 16 to 16.5 mh/s

To reach 1150/1500 I had to use the MSI OC Gamer cards.

Anyway, good luck buddy.

7800 watt a single six rig gpu? this is craazy mate, soemthing is wrong there, at best it should pull about 1500 if you are using 390 or worse heavy gpu

there is no way you are reaching 7800, probably a typo right?

'The right to privacy matters'

I heard back from pro vantage they do not stock as of yet. But this could be a good thing as between us we have

most every make and model of the rx 480.

So if we all test them over the next week or so we would know which is best.

We can then decide if chipping in on an order for 50 cards makes any $$ sense .
