I did some searching and found some reviews that covered Thermal and Power consumtion for all of these cards. The summary table is below, and while its not sane to simply divide the Temp by MH, it still gives you a fair idea of the heat generated by the card and its cooling, now keep it mind, this is probably done on a test bench with adequate airflow for the card. Another point to note is how much Power and Heat is caused by 1GB of memory. The difference in the 6950 1GB + 6950 2GB is memory. So for those with dedicated rigs.. Underclock your memory and save as much power and heat as possible! Model | MH/sec | Heat (Deg C) | MH/Centigrade | Power (Watts) | MH/Watts | 5770 | 200 | 33 | 6.06 | 213 | 0.94 | 5830 | 300 | 60 | 5.00 | 263 | 1.14 | 5850 | 335 | 38 | 8.82 | 237 | 1.41 | 5870 | 420 | 35 | 12.00 | 270 | 1.56 | 5970 | 780 | 41 | 19.02 | 462 | 1.69 | 6870 | 300 | 44 | 6.82 | 247 | 1.21 | 6950 1gb | 240 | 46 | 5.22 | 278 | 0.86 | 6950 2gb | 350 | 54 | 6.48 | 306 | 1.14 | 6970 | 350 | 54 | 6.48 | 306 | 1.14 | 6990 | 770 | 63 | 12.22 | 475 | 1.62 |
One thing to note above is that while the power consumption is represented accurately for the 5970 and 6970, temperature is not. Since these cards have two GPU's, the single value for temperature needs to be adjusted accordingly. And one thing to note is that the 5970 has one fan at the far end of the card, and only cools one of the gpu's effeciently, the other one always runs very hot. The 6990's do not suffer from this problem because it has two fans a fan in the middle, afaik. Looks like the 5870 is the king of the jungle. Sources: The 5830's are anything but efficient. It is however the best price/performance (not efficiency) if you can find it cheap enough... I picked up a few at $109/card.
By using the data from the mining harware comparison, here's a power effecincy comparison:
5830: 300 MH / 200 W = 1.5 MH/W 5850: 335 MH / 180 W = 1.8 MH/W 5870: 420 MH / 210 W = 2.0 MH/W 5970: 780 MH / 350 W = 2.2 MH/W 6870: 300 MH / 175 W = 1.7 MH/W 6950: 350 MH / 200 W = 1.7 MH/W (2GB Unlocked) 6970: 350 MH / 200 W = 1.7 MH/W 6990: 770 MH / 410 W = 1.8 MH/W
As you can see, the 5830's actually as bad as it gets for price/power efficiency, but if I found them cheap enough i'd surely pickup a few.
As far as building the most power efficient system I dont think its worth worrying too much about CPU/Board/Memory. For a dedicated miner, the CPU usage is minimal, and thus the power draw by CPU is negligible (unless you're also going to CPU Mine, but why?).
So, in the end, you're left with the GPU as the deciding factor in how efficient your rig is. Refer to the table above and just pick whatever's available..

Stuff as many radeon 5830's in a motherboard as possible with optimal cooling.
Nothing comes close in terms of price/efficiency, unless you can get a really good deal on 5850s or a dual gpu.
They're mostly sold out though.

Good stuff! For people who don't want to use snmp (or just have a few rigs and not a dozen) they could use my custom solution "rug monitor", link in the sig. (Shameless self plug) Cacti is great for this kind of monitoring and infact has quite a few recipies to monitor basic statistics, so you can keep an eye on memory usage/cpu usage/disk etc along with miner statistics. You should check it out and give it a shot instead of just using rrdtool with php-cli

I setup cacti to graph some metrics of my miners and the overall health of my systems. If you wanted to, you could expand on this and acutally graph pretty much everything, your hash rate, number of shares submitted etc from the JSON API provided by some of the pools...hmm, maybe that should be my next step. Anyways, here are the notes: http://saaboke.com/?p=264-js

Hi everyone, I just spent some time tweaking my shell script that I use to manage my miner instances. Features: * Central control of all miners - lets you switch pools on demand - the address of the pool you connect to is fetched from your web server * Email alerts - yummy spam! * Overheat protection - can shutdown miner at preset threshold * Idle Miner protection - can restart stick miners You can get it here: https://github.com/jsidhu/Bitcoin-Miner-ScriptHere's the Readme:
This is a script that manages your bitcoin miners.
This will start phoenix in a detached screen session, the screen sesion name is set to the MINER_ID-Miner as specified in the settings.
For phoenix miner to work in a detached screen session, you should edit your ~/.screenrc and set the appropriate environment variables, I have the following in my ~/.screenrc
setenv LD_LIBRARY_PATH "/opt/AMD-APP-SDK-v2.4-lnx64/lib/x86_64/:/opt/ati-stream-sdk-v2.1-lnx64/lib/x86_64/" setenv DISPLAY ":0"
--
Logic/Thinking:
This script uses a file hosted on your web server to figure out where to "point" your miner to. It also checks to make sure that the Temperature of your GPU is under a set limit and that the LOAD on your GPU is above a specified threshold.
IT requires that you have wget and sendemail installed. To install both of these packages, issue a apt-get install wget sendemail
* please notice that its sendEmail, not sendMail
Here's what it does, run in a infinite while loop:
0) Kill any old instances of the miners that may be running (Cleanup) and start the while loop from #1 below 1) Fetch your control url 2) If #1 fails, sleep and repeat the main while loop 3) Check if miner is running, if not, start it using the address from step #1 above 4) Check if the address currently in use is different from #1 5) if so, kill the currently running miner (when we loop next time, we start with new address) 6) If address has not changed, check if Temp is under limit, if Temp > Threshold, kill miner 7) Check Load, if load is under threshold, sleep 15 seconds 8) Check Load again, if load is under threshold, kill miner, (When loop repeats, it will start miner)
The recheck period is 10 seconds, and we recheck only under these conditions:
* If miner wasn't running and we just restarted it * If the miner was killed because load was under specified threshhold
Aside from those two conditions, the loop repeats in 300 seconds (5 minutes)
Configuration:
The configuration settings are at the top of the script, here is a bit more detailed description of everything
CTRL_URL - this needs to point to something that returns a phoenix-friendly URL
MINER_ID - this is an idintification string to differentiate different screen sessions for people that have multiple GPU's in one system ATICONFIG_ADAPTER_ID - this should contain an integer as you would specifiy for --adapter=X when running aticonfig for checking Temperature and Load
PHOENIX_OPTIONS - this is an entire string of commands that you pass to the phoenix miner
MIN_LOAD - if the load on the GPU drop below this limit, we'll kill the miner MAX_TEMP - if the temp reported by aticonfig goes above this limit, we'll kill the miner
ENABLE_EMAIL - set this to 1 if you want to recieve spam/email alerts from your miner
# some basic email settings FROM="user@host.com"; TO="user@host.com"; SMTP_SERVER="10.1.0.58:25";
# Logging ENABLE_LOG=1; # 1=enabled, anything else will disable it LOG="/tmp/Log-$MINER_ID.log"

yeah, I just got it running today. 2x5970 + 1 6870 on Linux.
The 6870 will not work with ati stream sdk 2.1, you need to upgrade it to the latest AMD APP SDK2.4 .
So far i've had the best performance from 2.1. So i'd recommend using 2.1 for everything that it works for, and use 2.4 for the newer 6X cards.
To use both 2.1/2.4 you add both paths to your LD_LIBRARY_PATH, i.e. make sure you have the path to 2.1 and 2.4 libs in there. If you do this, the miner, ex phoenix, will see this as a second platform. SO you can use 2.1 for your older 5XXX cards and 2.4 for the newer 6XXX cards. 2.1 was the fastest for me for my 5970s, so I'd recommend 2.1 for everything, and if that doesn't work, use the 2.4.
export LD_LIBRARY_PATH=/opt/ati-stream-sdk-v2.1-lnx64/lib/x86_64/:$LD_LIBRARY_PATH export LD_LIBRARY_PATH=/opt/AMD-APP-SDK-v2.4-lnx64/lib/x86_64/:$LD_LIBRARY_PATH
make sure u specify the PLATFORM=0 or PLATFORM=1 when accessing the different versions of the sdk.

pm me or get in touch with me in the irc channel, looking to purchase, perhaps even a larger quantity..
