Same as always, BTC going up, ETH going down.

logical. When BTC goes up, all alt coins go down. Not only ETH

Yup. That's because of the price change as btc goes up, the other coins follow down to match previous price.
Rarely, the altcoins stay high temporarily and you can make some extra $$ on the price moves.

This is with no news or pumps involved on a static altcoin price.

Same as always, BTC going up, ETH going down.

But the Ethereum price in US dollar is not down so much. Ethereum is in the correction phase at the moment.

what correction ? Eth price was $15 and went down to $8.5 or less. Is it a little change ?

Eth bubble is over. Back to 0.003?

Eth bubble is over. Back to 0.003?

That would sure be a great opportunity to buy a lot more 😀 But seriously the price is around 0,02 BTC/ETH. I am currently holding at a loss, but I intended to keep my ether for my kids. Unless Ethereum tanks and everyone goes home, I am sure that whatever prices we have today will be laughable in 20 yrs time, if we have a global financial system that is based on crypto contracts. It's all what perspective we have, so at least in my eyes the current prices aren't something worth worrying about.

ETH not going anywhere anytime soon, id advise invest elsewhere, then buy back i have hopes it will hit 0.01-0.015btc currently shorting it from 0.035btc

Ok, thanks for the confirmation.  I first tested it out with just one 390x connected via 16x riser, and that worked great.  Then, I installed TeamViewer, shut down, connected the other GPUs via 1x-16x risers, and restarted (without a monitor plugged in.  I thought I could just then use TeamViewer to connect and start up the mining software).  After work, I'll try restarting again but with a monitor connected during bootup to see if the other GPUs get started.

I've got 2x 1000w platinum PSUs to power the 6 gpus.  Should be enough.  While testing though, I've only got the 3 connected with 1 of the PSU.  I think 1000w is enough to power those 3 cards though...

No Prob.

The 390x's shoudl draw stock about 250watts each, the 280x's about 230watts or so. (as long as they are good quality cards).
'Most' 390x's you can undervolt and get back about 10-20% wattage, some more, some less.
I run all my 390's (non 'x') at 100mv undervolt, 1100/1500 settings (stock is 1015/1500) and they use 200-210watts each while getting around 29MH+ now.
Solo mining has been earning me 50% more than pool mining for the past week so I'm sticking to it. Some days I get 1, some days I get 5 blocks.

Well shit.  So I got home, plugged in the monitor (with all 3 gpu's connected, 2 via 1x-16x risers), and booted.  Still, only the one connected to the 16x pci slot powers on and is recognized.  I've got the molex power connector on the mb plugged in, and all 3 gpus have dedicated power which I made sure what all connected.  My PSU is an evga "supernova", so no issues with psu quality I think.  I know it's not the gpu's because I swapped out one of the ones connected via the 1x-16x riser to the 16x-16x riser, and that one powers up just fine.  Only the ones connected via 1x-16x.  Anyone have tips for how to troubleshoot this?

Edit:
MB is an ASROCK H81 pro btc,
2x 280x are both Sapphire,
4x 390x are all MSI.

i'm using windows 7 64bit

1x to 16x risers

old 80gb hdd's , 2gb ddr2 RAMs

good old socket 775 cpu's and motherboards @ 4 cards each. all fine, i'm using only one monitor that i plug if remote access troubleshooting is not possible.

sometimes it is better to have at least two rigs, a few extra risers and a spare PSU that you are very sure that is 100% working. swapping components to compare and check to know what component have trouble.

from experience i've seen motherboards that cannot detect more than two or three GPU's (know that i'm using cheap old boards), there are two 1x to 16x risers here that makes my gpu's undetectable (this have been used for quite a while).  

it is also good to have a GPU temperature monitoring software around. to know what card is heating more etc.

last day one of my miner hanged twice, unplugged my hottest card, found out the my high speed hydraulic fan is not smooth anymore (rotating) (from modded old sapphire 280x), removed the cover underneath the sticker, put some compressor oil (just lying around here) returned the cover, seal it with a piece of masking tape (fan fixed-smooth again)...... and reapply thermal paste to the card because it was already dry.. and the rig was fixed and mining again

Ok, I'll try swapping out the risers.  The ones I bought are here:

Otherwise, I know that my MB is a common one used for mining.  It's part of the mining series ("Pro BTC") mb's from ASROCK.  I guess I'll also try different pci slots to see if that makes a difference.

check the review at newegg of your "pro BTC" board   , i think someone there have the same issues like yours

i don't like the design of your riser, the riser should be molex compatible, extension-adaptor wire can sometimes be a point of failure, and the usb wire is kind of short in length.

here is one of my rig. the motherboard is mining for me for about 2years now



newegg review or my board



a spare riser..

Ok, I figured out the problem: the USB risers I bought are powered, and they must be connected to power to work.  I guess the USB riser part only takes power from the molex connector it comes with, not from PCI slot, so it has to be plugged in for the MB to even see that there's something in the pci slot.  I now have 3 gpus hashing happily away!

These are my first AMD gpus though.  with latest genoil miner, i'm showing right around 68-69 mh/s (1x 390x & 2x 280x).  I thought it would be higher than that...Anyone care to share a config that's better tweaked?

[smaxz]

lol so you thought the molex and usb slots on the riser board were for whatever option you felt like using?

|facepalm| glad you sorted this one out.

that does sound like a low hashrate for your card configuration

  well, the board has 2 4pin molex on it which I have connected to the PSU.  Plus, those cards also have dedicated power from the PSU, so I figured connecting the power on the risers wouldn't really be needed.

Owell, lessons learned.

lol, 16x slots have more power because some lanes in the 16 lanes are power source, that's why those 1x to 16x adapters needed an external power source going through that sata adapter.

maybe you can try claymore's dual ETH, DCR miner..i think you might like it

it's time to hold your eth 

[Maicol792]

Hello, i have on question, i mining eth with 2 PC on suprnova one r9 270x and one r9 290x ..and i have near 45 mhs ... 15 + 30 mhs ...
now on eth mining profit calculator i have this results:
X Hours: 0,029
X Day: 0,69
X week: 4,89

But my real production on suprnova.cc is:

X Hours: 0,020
X Day: 0,397
X week: 2,19

Why? My near 45 mhs are unstable? Where i have the problem?

Thanks

All the +12V lanes are in the front PCIE1 part. There are 5 lanes in total. The +3.3V and 5V are in the x16.
