Do you need two different btc address for two miners?

Nope, you don't have to.   Most just use one address for multiple rigs.

Noticed the coin diff this morning is 135.  That isn't doge.  Wonder what we are mining and if we are giving doge a break.

RickJamesBTC,

   What OS are you using?  I have been unable to get 6 cards working on a system despite trying BAMT/Win8/Win7/SMOS for like 2 days.  I had to settle with 5 cards per rig, which ultimately made me have more rigs because of not being able to have 6 cards in one.

Balanceboost, going to be a good payout day, nice

I'm running four 6 GPU rigs. Here is a guide:

Let us know how you get on.

Just editing to add the details of my 6-GPU rigs rigs..

 - Windows 7 Pro (completely up to date)
 - AMD Catalyst 13.1 from TechPowerUp
 - Gigabyte GA-990FXA-UD3
 - 6x R9 280X on ribbon risers (4 powered)

Not directed at me, but I'll respond anyway.

The biggest surprise I had to get 6 gpus running in one rig, was that I had to use a presence detect short on slots that were described as not needing them (mb z77a g65). Oh and if you do use presence short, dont f**k up your pcie slots by forcing some extra wire into them. Simply cut & connect the appropriate wires in the riser, much simpler and less invasive. Connect B17 to ground (B16 or B18 will do just fine, no need to go to A1).

Use a win98 boot usb stick with "atiflash -i" to see if they are detected by 'the hardware'. If they are, but do not show up in windows, or report error 43, it's a driver thing. If they do not show up for "atiflash" you'll probably need a presence short. No amount of driver juggling will help you in that case.

Which OS if you don't mind me asking? I have 10 rigs with that motherboard running 6 cards on each under BAMT, and no shorts were needed.

[MrBobC]

It would be the driver set found here then?

I'll be running 6x R9 270.  I have 20 rigs, and if I could get 6 cards on them, it would increase my utilization.  I have some R9 280X and R9 270X as well though.  My 270X rigs have the MSI Z77A-GD65.  I'll have to look into the short via the riser.  I use 16x -> 16x risers for the 16x slots, and 1x -> 16x for the 1x slots, although I have 3 of the Pro BTC boards which will be using 1x -> 1x.  Thanks for the pointers!

Win 8, but that shouldn't matter as they weren't even detected by atiflash without the shorts.

Mind you, I am using 1x-1x risers for all 6 cards so perhaps that is different from your setup.

The file I used when installing on my 6 GPU rigs is 13-1_vista_win7_win8_64_dd_ccc_whql.exe (149,984 KB).

Should I stay on middlecoin or move to doge pool? Where is more profit?

Just use the latest SMOS Linux or Litecoin BAMT. To get 6 cards running, you will need to start it up with 5 and drop out to a terminal window. Then su and:

nano /live/image/syslinux/live.cfg

Change:

kernel /live/vmlinuz

To:

kernel /live/vmlinuz vmalloc=256M

Shut down the rig, add the 6th card, and you should be all set on the next boot.

Not sure how reliable 'atiflash -i' is for this as one of my rigs would only dump the ROMs from 5 cards, the 6th didn't exist as far as it was concerned, however when I went to flash them (straight after dumping -- no reboot) it would flash the 6th. Windows detected all 6.

Just load balance between here and a doge pool.  Best of both worlds!

Looks like a lot of those unexchanged are selling.  Gonna be a heck of a payday today!

Bring it on!! I'm afraid to go to sleep incase a rig goes down..

  Glad to see I am not the only one!!  Also it appears that when you are waiting for UPS to bring more GPU's to your house, tracking the package every 5 seconds does nothing to help it arrive faster.

 Also, going outside in -22 C temps and checking for the truck on your street, not effective.

[CaptainBeck]

Should be another good payday today and yesterday appear to be twice the normal payout.

Hate what H20 is doing, he needs to steal more from us.

Guys, do you think my WU is too low? Can i do better? (screen from 2,5 hours of running)

my config (those are 3x 7970): http://cgminer-config.com/getConfig.php?id=11
And I have removed gpu-fan line making fans run on 95% speed. It was stupid . I agree. It's cold in that room anyway.

Weird!
