5 x Sapphire Radeon R9 290 Tri-X OC setup!

[kwn]

Hi guys,

I got 5 x SAPPHIRE TRI-X OC 100362-2SR Radeon R9 290 4GB 512-bit GDDR5 Video Cards coming my way today!!!

Now I'm still deciding on what motherboard to get.

What is the best mobo to get for a 5 gpu setup that's not too finicky something that will just be reliable. (at the time that this is written)

Right now I'm looking at the
GIGABYTE GA-Z87X-OC LGA 1150 Intel Z87 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
vs
ASUS Z87-WS Socket 1150 WorkStation ATX MB (Z87-WS)

Also I'm open to other suggestions on mobos.

I don't have risers right now so I'm looking to house 4 of these cards per one mobo without raisers. (because I don't have any at this moment also not sure which to buy!)

Also what power supply should i get!?!?!

Much appreciated!

Thanks

Hello, I would like to know the configuration of your cards cgminer

I just picked up 4 of these cards myself.

You will probably need a very high-end PSU to run them(1600W minimum) or have a dual PSU setup since they're overclocked. 

They run hot. I would not recommend putting more than 2 on a MoBo without risers.

I recommend powered risers. I had a lot of hardware errors with unpowered risers.

2 PSU at the board ?? SOURCE ?

You need x1-x16 powered risers like these.  4/5 290s inside the board all scrunched up is a very bad idea.

Mainboard: MSI Z87-G45  
 >>> About as good as you are will get for slot quantity and arrangement / affordability for the LGA1150 stuff.  You could do 2 up, 3 down for maximum spacing / airflow.  So, 3 powered risers linked up top.

PSU: 2 x Seasonic Platinum 1000w
 >>> My 4 290 rig pulls 1320w from the wall with each card @ stock volts + 965/1475.  You can easily figure each 290 for minimum 300w at stock clocks.  In other words, your typical 1500/1600w unit will be maxed out by the cards alone..  You will need a little device like this to get both power supplies working at the same time.

Ignore the mining boards from Asrock / Biostar until they come down in price.  They are novelties until supply meets demand.

Our 290 (non-x) pull ~330W per card. Our 5 GPU rig pulls ~1750W.

Sounds about right. I'm running a 1300 Watt PSU and was trying to get 4 of them going. Once I dropped to 3, my stability suddenly got 100x better.

Hey atp, what's the difference between sgminer and cgminer? Just a guess, but is sgminer designed for scrypt and has support following the cgminer 3.7.2 version?

SGMiner is the logical gpu-only extension of cgminer, but maintained by someone else.  SGMiner fixes some very critical issues with cgminer and gpus.

I highly recommend it, especially if you have 7950s.  My WUs have never looked better on them with the optimized bins.

I would love to see other peoples config file.

Have you got 5x 290 Tri-x setup yet?

Interested to see if they are stable, as the R9 290's are hit and miss with more than 3.

Hello, what is the cheapest board you would recommend for two R9 290?

I currently have an Asus F A55M LE running with two R9 280x and its all good I get about 730kh's each one

Looks like you are connected to middlecoin - you should drop --no-submit-stale for that pool.
