I'll have some time to work on it tomorrow, but since the i2c calls in the ADL api are virtually undocumented and may not actually do anything, I can't promise anything.

i can overclock on 11.5, using amdoverdrivectrl to downclock mem outside bios limits, and gpu clock rise only to bios limits with 11.6 and 11.7 u can set whatever you want, but cpu usage bug forces me to rollback to 11.5 Bummer. What's the cpu usage bug? I haven't noticed any problems -- top reports about 5% cpu usage with 4 instances of phoenix running.

im using catalyst 11.5 because of cpu usage bug and cannot simply change clocks to whatever i want
been thinking that your tool will allow to do this
I jumped directly from 11.4 to 11.6, so I don't know if the limitation issue was fixed in 11.5 or 11.6. Can you overclock with aticonfig? Both tools use the same underlying API, so if aticonfig works, atitweak also works.

mjmvisser, can your tool oc over bios limitations ? or if not now, maybe in future ?
Yes, with the 11.6 drivers you can over/underclock outside of the BIOS ranges. You can use this tool or aticonfig, they both call the same underlying API. atitweak --adapter=$1 --set-fan-speed=100 atitweak --adapter=$1 --set-engine-clock=950 --set-memory-clock=300 --performance-level=all atitweak --adapter=$1 --set-engine-clock=850 --set-memory-clock=300 --performance-level=1 atitweak --adapter=$1 --set-engine-clock=750 --set-memory-clock=300 --performance-level=0 (replace $1 with the adapter number) These are well-ventilated and run between 75 and 85 C. I'm unable to push the engine clock higher without OpenCL errors or freezes. Some people are successfully overclocking even higher by also boosting the voltage. Right now, the only tool on Linux that can overdrive the voltage is radeonvolt. It doesn't work on my cards (not reference 5850s), so you're on your own there. cheers, -Mark

Can't get or set fan speed for dual gpus like 5970. Fixed -- now prints a warning instead barfing when the _Get call fails. I don't have a 5970 to test with, can you try it out? I just replaced the 0.3 version at pypi, so you may need to remove it and reinstall to get the updated code. cheers, -Mark

UPDATE: adl3 v0.3Features:I've added a few more parameters to atitweak: -f / --set-fan-speed Sets the fan speed (in percent) for the selected adapters.
-d / --set-fan-speed-default Resets the fan speed to its default setting.
-s / --status Displays current clock speeds, core voltage, utilization, performance level and fan speed.
Also, -l / --list-adapters now shows fan speed range. Bug fixes:If DISPLAY is not set, it is assumed to be ":0" and set before ADL3 is initialized. That's all for this release! See the original post in this topic for (updated) installation instructions. If you're using easy_install, you may need to explicitly state the installation version: "sudo easy_install adl3=0.3" Next version:I'm looking into using ADL3's i2c API to set the voltage, which if possible, should allow bypassing the BIOS voltage range. Donations are very welcome! 1Kh3DsAhiu65EC7DFFHDGoGowAp5usQrCG cheers, -Mark

works like a charm, but Í've seen some strange bug...
when trying to overvolt the stock voltage (from 1.088 (stock) to 1.150), I get failed (obvius) and then the my miner rate just drops and with list it shows the voltage at 1.150
Do you get the same result with AMDOvDrvCtrl?

If he's trying to be a trademark troll, he'll fail hard. The moment he tries to extort money from one of us, let us know. It's easy to build a legal defense fund when we can send money near-instantaneously and anonymously.

Will this allow me to get past 900Mhz on my XFX 5830 and 875Mhz on my Sapphire 5830? I'd love to get to about 950 on each card if possible.
I just tried on my 5850 and it won't allow me to go beyond its maximum. atitweak uses the same method to tweak settings as AMDOvDrvCtrl, so you if can't overclock with that tool, you can't overclock with this one.

As far as im aware, the original AMDOverdriveCtrl cant actually raise the voltage above the default? Can this?
I haven't tried, no desire to fry my cards.

Hi everyone, I'm an experienced software developer who set up a mining rig last month using Ubuntu. I found the overclocking tool available for Linux (AMDOvDrvCtrl) was a bit annoying to use, so I took a look at the source and decided to write my own command-line version. Rather than write one in C or C++, I figured it would be much more useful to wrap the underlying libraries using Python's ctypes package so I could write the tool in Python. This means no compiling, no installing an SDK, and you can read the code yourself to make sure there's no funny business going on. Anyway, I'm done and the tool is available. You can install it in a few different ways: From github: https://github.com/mjmvisser/adl3From PyPi: http://pypi.python.org/pypi/adl3/0.3With Python's "easy_install": sudo easy_install adl3==0.3 If you don't use easy_install, you'll need to run "sudo python setup.py install" to install the package after you download and unpack it. Included is the "atitweak" tool. It can list your adapters just like aticonfig: $ atitweak -l 0. ATI Radeon HD 5800 Series (:0.0) engine clock range is 80 - 918MHz memory clock range is 150 - 1200MHz core voltage range is 0.95 - 1.088VDC performance level 0: engine clock 800MHz, memory clock 300MHz, core voltage 0.95VDC performance level 1: engine clock 918MHz, memory clock 300MHz, core voltage 1.088VDC performance level 2: engine clock 918MHz, memory clock 300MHz, core voltage 1.088VDC fan speed range: 0 - 100%, 800 - 5100 RPM 1. ATI Radeon HD 5800 Series (:0.1) engine clock range is 80 - 918MHz memory clock range is 150 - 1200MHz core voltage range is 0.95 - 1.088VDC performance level 0: engine clock 800MHz, memory clock 300MHz, core voltage 0.95VDC performance level 1: engine clock 918MHz, memory clock 300MHz, core voltage 1.088VDC performance level 2: engine clock 918MHz, memory clock 300MHz, core voltage 1.088VDC fan speed range: 0 - 100%, 800 - 5100 RPM It can also change the engine/memory clock speed and core voltage individually for each performance level and adapter: $ atitweak --set-memory-clock=300 --performance-level=2 --adapter=0 Setting performance level 2 on adapter 0: memory clock 300MHz new! You can set your fan speed (in percent) for each adapter: $ atitweak --set-fan-speed=100 --adapter=all new! It will also show the current status of adapters: $ atitweak --status --adapter=0
0. ATI Radeon HD 5800 Series (:0.0) engine clock 950MHz, memory clock 300MHz, core voltage 1.088VDC, performance level 2, utilization 99% fan speed 100% (3447 RPM) (user-defined) temperature 85.5 C
Here's the full command-line help: Usage: atitweak [options]
Options: -h, --help show this help message and exit -l, --list-adapters Lists all detected and supported display adapters. -s, --status Shows current clock speeds, core voltage, utilization and performance level. -e ENGINE_CLOCK, --set-engine-clock=ENGINE_CLOCK Sets engine clock speed (in MHz) for the selected performance levels on the selected adapters. -m MEMORY_CLOCK, --set-memory-clock=MEMORY_CLOCK Sets memory clock speed (in MHz) for the selected peformance levels on the selected adapters. -v CORE_VOLTAGE, --set-core-voltage=CORE_VOLTAGE Sets core voltage level (in VDC) for the selected performance levels on the selected adapters. -f FAN_SPEED, --set-fan-speed=FAN_SPEED Sets the fan speed (in percent) for the selected adapters. -d, --set-fan-speed-default Resets the fan speed to its default setting. -A ADAPTERLIST, --adapter=ADAPTERLIST Selects which adapters returned by --list-adapters should be affected by other atitweak options. ADAPTERLIST contains either a comma-seperated sequence of the index numbers of the adapters to be affected or else contains the keyword "all" to select all the adapters. If --adapter is missing, all adapters will be affected. -P PERFORMANCELEVELLIST, --performance-level=PERFORMANCELEVELLIST Selects which performance levels returned by --list- adapters should be affected by other atitweak options. PERFORMANCELEVELLIST contains either a comma-separated sequence of the index numbers of the performance levels to be affected or else contains the keyword "all" to select all performance levels. If --performance-level is missing, all performance levels will be affected. So far, I've only tested this on my own rig (quad 5850s) so it would probably benefit from testing by experienced users. UPDATE: I've verified that over/under-clocking outside of the BIOS range is possible with the Catalyst 11.6 drivers. This should be obvious, but... WARNING: This software may severely damage or destroy your graphics card if used incorrectly!Please try it out, and let me know if you find any problems or bugs. Donations welcome! 1Kh3DsAhiu65EC7DFFHDGoGowAp5usQrCG cheers, -Mark

It has frequently been stated that most client users do not allow incoming connections. As bitcoin is a distributed system which relies on the mesh of nodes exchanging block data. it seems very selfish to set up a node and not allow others to connect to it. So why do so many people do it? Even being on DSL with a dynamic IP address is no excuse unless there is more than one node on the LAN, as even the cheapest DSL modems can be configured to forward incoming connections on a port to a system on the local LAN.
For a long time, uPNP was off by default. I think it's on, now. Either way, there will be a patch release soon that fixes a bunch of problems due to the size of the block chain that makes downloading new blocks slow.

When AES encryption is completely broken, bitcoin will quite obviously collapse. Give it five-seven years tops.
Not only will AES encryption need to be "completely broken", but someone will need to break a new hash every 10 minutes. I think that will take a little longer than 5-7 years. Even quantum computers only reduce the difficulty required to break a hash. And, there's nothing stopping Bitcoin from switching to a "harder" encryption algorithm. QC isn't a magic pill that solves all computationally hard problems effortlessly.

Unfortunately Windows is a popular target for phishing/trojans because it is widely used, is known for having many security holes, and encourages users to run as "Administrator" at all times. Using Mac or Linux will make you less of a target. You can still secure a Windows machine, see here for more details: https://en.bitcoin.it/wiki/Securing_your_wallet#Windows

My name is Mark Visser. I'm a developer and have written a Python package that wraps the AMD Display Library using ctypes. This makes it easy to over/under clock ATI graphics cards, change the voltage, fan speed, performance levels, etc., without having to write anything in C or C++. I've had this account since December, but haven't felt the need to post until now. Just doing my posts so I can get out of here!
