Tmdz,

I will take a look at the riser, that sounds similar to my story. Either way, I am glad I'll be getting away from risers. I hear not so flattering things about them. I have the cards spread across multiple machines until the new rig comes.

Risers suck..  I mined with a ton ( 21-24 at 6kwatts)    of btc gpu's back in 2012.  cards pulled more power then and riser were really not reliable.

that Biostar mobo is very interesting.... is there a good 5 x PCI version?

so far four is the biggest I can find.

i tried undervolting a stock 480 using wattman and its allowed me to underclock only -33 mV

is this normal?

on my Nano, using Afterburner, I can get -100mV or -96mV

not the same unit of measurement.

-33 on watt man is a percentage

-33 on afterburner is mv

phillipma,

check your +12V cables of your motherboard ATX connector. Touch it maybe to make sure its not burning hot.


I am really surprised that motherboard can handle delivering all that power to each of the 4 cards thru the slot.

so far four is the biggest I can find.

There are some server boards that have 5,6,7 x16 slots (physically, not electrically) but the slots spacing does not work for these double-wide cards.  You'd still need x16 ribbon cables to make that work, most likely.

is 33% reduction the max for 480?

Things have now regressed. I think my Mobo and CPU are struggling to boot all 3 cards. I have an older Z87 chipset and i7 875k CPU. It will not consistently recognize the cards. PCIe speeds are suspect at this point. I have to manually set Gen3 speed. It will not accept auto detect, nor and speeds below Gen3

i assure you a properly set up and bog stock, comparatively weak by todays standards cpu like an q6600, has NO problem with a r9 390 and r9 380 with a hd6870 mining crypto. and it gets 21 mhs and 31 mhs at eth, which is exactly right with others gpus. oh and plus sia and decred as dualies

you setup is wrong somehow.

 My "big rig" ran a Semperon 145 (SINGLE CORE semi-current CPU) to support 3x R9 390s for quite a while.
 No issues.

 Only reason I swapped a X240 dual-core into it was that the MB the X240 was on died, and I figured long-term I might need more CPU if/when Ethereum gets unprofitable and I need to do other stuff on that machine.


 The MOST dual-width cards that will physically fit on any ATX board is 4 - there are a few different motherboards with applicable spacing, though the Biostar "Racer" one linked above is the lowest-cost new board that can manage that.
 ATX spec calls for a maximum of 7 slots TOTAL, which is the core limit.
 I specifically remember an ECS varient with the same theme, 1 or 2 others with the same theme but I forget what brands, and there was the one Gigabyte with *7* PCI-E 16 slots (they obviously didn't all RUN at 16x at the same time of course).

 Server boards and PCI-E "expansion" boards that can handle more than 4 dual-slot cards plugged into them are ALL very expen$$$ive - you can build a complete SYSTEM with 4 RX480 for just the cost of some of those server motherboards ALONE. NOT WORTH IT.

they started to show up around here, but i am holding for custom made, not reference cards, which should be better value in both cooling and resale.
i really like my msi r9 390s, so might try msi twinfrozr VI (overclocked with 8pin connector and 175 TDP), which some say are imminent.

So your +12V into your motherboard slot isn't hot?

   no remember  you have 4 wires and 2 wire going in a total of 6 wires.

I did a infra red gun and the two  are under  40c.  like 38c.

Hint cpu jack has 4 hot wires and while many think it is all cpu  many mobo's pull some power from it.

I tweaked more  and am doing 592 watts and 102mh for the 4 cards. this is at the
kill a watt and reflects the entire power used by the system.

That's pretty impressive.

So if power consumption wasn't an issue whats the fastest that the 480 can mine at? 29MH/s ?

Maybe 28  or 29  .

The ram memory can set to 2200/8800  with wattman for tweaking the gpu   and with claymore to mine 28 for sure maybe 29.

This card is far better then the r9 390.  I can get that one to do 33mh  with heavy overclock and claymore but is sucks up tins of power.

For me  power is important and heat is more important.

I have the 4 card rig all rx 480's  up to 102 mh at 590-600 watts.
I have 2  2 card rigs with   3 r9 390's and 1  rx 480  at 560 and 480 watts  they do 112mh

So  1630-1650 watts  for  214mh

In the summer  that amount of heat and power approaches my max.

It is about 1200 kwatts a month at 18 cents = 216 usd  but  I should earn 536 usd net 300

In the winter  it is about 9 cents or 108 usd.

I wish I had used  all rx 480's   

2 four card rigs at 102 each = 204 mh and 1 2 card rig = 51 mh   255mh net

power would be  1500watts
mh would be         251mh

vs my

1650 watts
214mh





In the winter I can see  me at  all rx 480's

3000 watts and  500mh

Phil,

I have 4x R9 390 - I'm reading in kill-o-watt 1320W from the wall (PSU 1300W Gold 80).

Can I use 3x R9 390 and 2x RX 480?

Or that will be overkill?

apparently the newest catalyst has some power-draw updates to limit draw through the mobo. Also helps that ethereum mining doesnt quite demand full power draw from the cards

theoretically the mobo should have the ability to safely draw 300W through the 6 hot 12v wires, enough to support 60-75w/gpu if the cpu/ram/fans attached to it are not power-ungry

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe

I am about to start a thread on mixing r9 390's with rx 480's

I just finished taking 12 photos.

I think 2 r9 390's and 2 rx 480's

will use 1010 to 1050 watts at meter  since 1 + 1 in my case is using  504 to 526  watts my meter reads 2.1 amps at 240 volts  but could be as high as 2.19  amps

So I think   2 r9 390's and 3 rx 480's  would use 1200 watts to 1300 watts (guess) as your  clocks matter

If you undervolte, you will not use more than 1000W with 3x 390 + 3x 480. So why do you need more than 1300W?
