6 GPU Sapphire Tri-X R9 290 OC (non-x) Rig

[vleroybrown]

I run 6 290s on the H81.  Solid as a rock for about a month but it does get hot   I have 4 MSI cards and 2 of the ones you ordered.  The MSI cards perform better then the trixs.  As far as PSU I went with 2 1050s from corsair and they have room to spare.  In the way of OS I jump around depending on what Coin is most profitable.  Right now posting this from win 8.1 on a SSD.  I have let Bamt 1.3 and 1.5 run over a week straight no problems.  SMOS for some reason has never booted all the way on this machine.  I recommend pick the winner alt coin, let her rip and not fooling with it.

Thanks for the positive feedback. Do you mind sharing your hash rates and settings?

[sonysasankan]

Don't go with what the graphics cards usually draw. You will be hashing, so peak loads is what you will be needing to look at. A list of peak loads can be found here: http://forum-en.msi.com/faq/article/power-requirements-for-graphics-cards

Multiple the A (Ampere) with the V (Volts) to get the W (watts).

In your case, the 290 hogs up 31 Amperes through the 12 Volt rails. So at peak load, it would consume 31 x 12 = 372 Watts each.

Also Don't forget to allocate some power for the motherboard, RAM and HDD... about 150 Watts should be fine.

Most decent PSU are 80% efficiency. That means you will draw up 1200W from the wall if you are using a 1000W PSU. You ca use that as a rough calculation to estimate your electricity costs.

[dloganbill]

I'm not arguing, but 2400W seems pretty high to me. Vleroybrown is running off of 2100W. Do either of you have actual kill-a-watt readings to share?

[vleroybrown]

At peak usage I  have a draw from one outlet on the wall of 1250 watts into a power strip that has the box fan, monitors, router, and 3 cards 2msi +1trix.  I only have the one outlet reading but the other plug only has 3 cards and cpu/motherboard so I think it is less.  Stable hashrate for scrypt I have gotten in the 6 gpu setup is 880kh per card.  If I pull the trixs off and run them solo/dual in another box, I have have had them upto 910 but didn't run this long so I don't know if that was stable.   Last week or so I have been running asic resistant and the hash rate is different.  My configs are different on each setup since linux is OCd in the config and on windows 8.1 I use TRIXX.  The thread count sweet spot is the 24550 with 2 threads per gpu. This is what my sloppy ass setup looks like right now https://i.imgur.com/05dHsjg.jpg

I finally got enough parts in to start assembly on the mining rig last night.  I’ve got the motherboard and GPUs installed.  Next I need to get all the power hooked up.

I have one 1050W power supply coming today but the 1300W PSU from Amazon still hasn’t shipped.  I hope to be able to start it up tonight and see if I can get two or three GPUs online.

Well I guess I have a lot more learning to do.  I plugged two cards into the MB and got them up to 700 kh/s with some settings I found.  Usually I have a pretty good knack for picking up new things quickly, but Linux was beating me last night.  I didn't have much time yesterday evening to mess around with it much, but it left me feeling like a moron.  I couldn't even figure out how to set the correct time in the task bar.  More importantly, I can't figure out how to get sgminer to run instead of cgminer.  At least the weekend is coming.  Hopefully I'll make more progress.

Are you using BAMT or SMOS or something else? Don't feel bad, Linux takes a bit to get used to if you're not already using it. No worries after a few headaches you'll get it working. If you're using SMOS go to the upgrades page and he has sgminer listed with some instructions, it was pretty easy to get going and I'm no linux expert.

I made some headway last weekend.  I gave up on Linux after being unsuccessful with BAMT and SMOS.  I installed Windows 8.1 and was mining in 30 minutes.  Amazon still hasn't shipped my 1300W PSU so I'm currently only running 5 GPUs with an 850W and 1050W.  Out of the box they were all running around 860 kh/s.  I've spent the last couple evenings tuning and things are looking promising.  
Things I learned along the way that seem to have helped:
1. Use Catalyst 13.12.  The 14.2 beta drivers were very unstable.
2. Don't bother with Trixx.  Install MSI Afterburner and use the settings shown on this post (link).
3.  I don't know if this helped or not, but I'm currently running with the bios switch toggled up (toward the end with DVI ports)

I think I can push them a little harder, but am currently limited by power.  The 1050W is essentially maxed out, so I have the engines turned down on some.  Here is my screen after 6 hours of mining.  I would have had a longer run time, except the power blinked last night and for some reason it didn't autostart like it should have.



Here are my current settings.

MMMMM. The sweet smell of a brand new mining rig running at full capacity.

What 's the vcc?

This is incorrect! Hashing does not use peak power consumption. Please use Kill A Watt metter and my 280x's undervolted use about 235-250 watts while hashing. If you plan 300 for each 290= 1800w and 250 for mobo = 2050w. Maybe give some more headroom above that if you want but I doubt you will need it especially if you are not overclocking your CPU.

[dloganbill]

I haven't touched voltages.

[mrmork666]

How is the noise of the rig?
when fans over 70%
at those clock speeds how much the fan % go normally?

[dloganbill]

I have the rig installed in my basement, so noise was never a big concern.  According to a decibel meter app it is currently 63-68 dB holding the phone about 1.5 feet away.  The screenshot below was taken with fans at

Code:

"gpu-fan" : "65,35,57,37,72",

Good news!  I got an email from Amazon today that says my 1300W PSU should arrive on Monday.  I'll finally get that 6th card mining and be able to tune harder.  As you can see below, the 1050W PSU has been overloaded for the last week.  My goal is a stable 945kh per card.  I'm also planning on trying out Stilt's BIOS soon.

[healthandwealth]

Looks nice!  My plan was to buy something almost identical to yours.  For 2 rigs:

GPU
R9 290 (x12)....6 per rig

MOBO
ASRock H81 Pro BTC (x2)

CPU
Intel Pen G3220 Haswell LGA 1150 Dualcore (x2)

PSU
Silverstone 1000W 80+ Gold (x2)
1300W 80+ Gold PSU (x2)
Dual PSU Adapter Cable (x2)

MEMORY
Kingston 4GB DDR3 1333 (x2)

SSD/HDD
SanDisk 32GB (x2)

OS
MS Windows 8.1 64 bit OEM (x2)

MISC
PCIe 1x to 16x Riser (x2)
Linksys Wireless USB Adp (x2)
Mining Case (x2)
~$8,000

For hopefully around 10-11 Mh (using wafflepool hopefully it pays for itself in 5-9 months).

How do you think this looks?  Am I missing anything?  Is it better to go with 3 or 4 GPUs per mobo...or is going with 6 per mobo alright?

I'm unsure of what kind of mining case I should get.  And would I need to plug in one rig into one wall outlet and another rig to another outlet I take it?  I was worried that perhaps one rig with 6 GPUs would be too much power for my apartment outlets.

Thanks for any input.   

[dloganbill]

I built my case from about $20 worth of stuff from Lowes. The rest of your list looks good. As for power, mine is currently pulling about 15 amps so I have it on two separate breakers. I'll get new amp readings once I get number 6 running. I recommend getting a couple $20 killawatts for setting things up.

As for ROI, altcoins have taken a big dive. I was originally planning on a 3-4 month ROI, but now I'm not sure how long it will take. $8k will take a while at current rates.

Hey guys

6 cards are coming my way tomorrow and I still do not know one key information.

I would like to buy 3x 850w power supplies, but I do not know how to connect them when all 6 cards will be on one motherboard. Can you give me a hint?
Do I just connect one power supply to motherboard and with 2cards, second power supply just with another two cards,third power supply to last two cards?

In that case, how do I turn the additional power supplies on, when the computer is starting up?


thanks
M.

[dloganbill]

To add multiple PSUs, you'll need one of these for each additional PSU. I'm using 2 power supplies so I only needed one adapter. You would need two adapters to run 3.
I am using this one:
http://www.amazon.com/gp/aw/d/B00DL3L2J6/ref=mp_s_a_1_2?qid=1394485633&sr=8-2

Many people are using this one:

Or you can go cheap and use this method:

[dloganbill]

I'm pretty frustrated at the moment. I finally received the 1300W PSU and installed it. When I went to power on, I would only get a single click out of the PSUs. It wouldn't boot to bios or anything. I started removing components and even with just ATX 24-pin and 8-pin CPU it won't boot. Cleared CMOS nothing. I'm guessing the motherboard has failed or CPU. Any ideas? It had been running pretty good for the last while. It had a few hangs in Windows that required a hard reset.
