I have two 5850 and one 5770 in my BAMT rig at the moment. The performance I'm getting is quite sluggish.
5850 1: 845/150 MHz, 303Mh/s
5850 2: 940/150 MHz, 324Mh/s
5770 1: 930/280 MHz, 215Mh/s

BAMT is using the default miner, phoenix I think. I've set aggression to 11.

I used to get 730 MH/s out of the two 5850 cards alone when they were in my Windows 7 workstation running cgminer, using the same clocks.

What do I need to do to speed things up?

Will using cgminer instead of the default miner make things go faster, or is this a driver/software version issue?

in general cgminer will sometimes give slightly better rates than phoenix, but sometimes not, depends on hardware and settings.  phoenix2 gives me slightly better rates than either of them, but I have limited hardware to test on so might just be me.  in any case the difference is a few mhash, not the difference you are seeing.

there are several kernel parameters you can adjust in the default miner.  probably just need to experiment.  you should get similar performance regardless of the miner you use.

Why not use a 77xx or 78xx card?  It's cheaper and works the same way o.o

why not do your job for half the pay? o.O

Thanks for the clarification. Also if you have 80 BTC in the fund. I will trade for a New Daimond HD7970 Reference if you can not find one cheap(Ill cover shipping if in US). I get deals on them from time to time. Thats why I have 9 of them with more on the way. Just an offer to help out.

Sounds good to me.  we should have 80 soon.  anything we can save on the card i'll put towards the next goal.

We have a donation pool going to get a 64-bit release that supports the 7-Series cards. Please donate!

To be clear, 64 bit and 7 series are two different issues.  Assuming the committed donations come through, we have enough donations for me to purchase a 7 series card, so I'll work on that next.

I sent a cgminer update script to be included in bamt, did it never make it in?

no, i was travelling for a few weeks.  back now, will look at some BAMT things in the next week, including that.

Can anyone comment on the benefits of manually upgrading cgminer to version 2.4.2 vs. just sticking with 2.3.1 which I believe was the last official BAMT fix/updated version. I have BFL's and they are working, I'm just checking to see if there are any noticeable performance gains or fixes worth moving to 2.4.2. Thanks.

Sorry if repeating the obvious , How can such a simple network connection exist in an enterprise ready OS ?

What is the best way to set a static IP via CLI ?

A new BAMT key is really easy to build, and from now on I'll limit access to root with a key only and not worry about it.  Should have done that for any internet facing box anyways.

I'm thinking the firewall was blocking his BNC bouncer, and that is why he kept trying with new user accounts. 
Are you going to pastebin his skiddie skripts for our enjoyment?
You can just google search "gosh.tgz" Smiley  Nothing fancy (sadly)

So someone was able to login to my box and create users.  I'm not sure how they did it as I have a rather long root password.  They made multiple users and then fetched a file "gosh.tgz" and extracted it in /tmp/ and /dev/shm/ and /home//.bash_history/

The location was different for each user.  gosh contains some scripts and BNC, an IRC bouncer.  They also stuck an entry in root's cron to run a script in /dev/shm/ to clear the user's history.

I'm going to build a new BAMT key, but for now I just looked at the histories of all of the new users (except the one that replaced .bash_history with a folder) to figure out where they stuck files and then deleted all the new users (easy to identify in /etc/passwd) and then edited /etc/sshd_config to only allow root without-password, so now my miner can only be logged into with a key.  

How much of the system was exposed to the internet? Like all ports or were you doing some port forwarding?
port 22 and 80 are all that are open. It's running ufw

I'm guessing they either cracked my root password or somehow broke in through munin.

It was clearly a person and not a script.  There were typos in .bash_history lol.  Things like ";s" instead of "ls"

Well the various scripts and whatnot are certainly not well audited for security flaws.  we don't have the budget for that type of thing Smiley

the good news is that short of disrupting your mining (which hopefully you would notice) there isn't really anything someone can do with a compromised box.  not like we store any actual btc or any credentials that matter on them.  bamt rigs are designed to be "disposable" not indestructible.
