= ClockTweak = win32 command line clock/voltage tweaking tool - NOW FREE!

[phelix]

Today after reinstallation of system on my miner the AMD GPU Clock Tool which previously was the only tool that could underclock and overclock over the BIOS limits my reference HIS 5850 refused to work.
The drivers installed were newest beta Catalyst 11.7. Then I've tried to use ClockTweak to do some overclocking in the BIOS limits range, but accidentally I've passed options for my second card - 900/300 and it worked! Not only the BIOS limits were bypassed, but previously this card could only go stable to 850. Very nice job AMD with that drivers

Radeon 6950 (three of them, #0,4,8)

clocktweak -a8 -c750 -m300

-r  gives me
#8 Temp 68 Load 96 Fan 32 CoreL2 750 memL2 700

However, the Win7 widget as well as the ATI tools show cpu840 mem1250.
after some testing, the widget still wont show the core and gpu rates i set via clocktweak...

what to do, what to do?

edit: also, when I set all my GPUs to 840/300 and the mining SW crashes - will the GPU continue to wor at 840, or will it slow down with diminishing load?

edit: do i need to disable all other tweaking tools, such as the AMD VISION CONTROL CENTER I am using in order to effectively use ClockTweaker?

I assume the download finally worked - sorry, missed your post yesterday.

are you sure you are looking at the right card? order may be different between programs.

without load the gpu will slow down to level 0 speeds.

it is safer to only use one tool at a time, especially with 10.x drivers

[2weiX]

download worked, program works as well.

on my sapphire 6950s, only a few select combinations work:

-c840 -m800 (-c840 with any lower setting than -m800 will result in -m1250)
-c800 -m700 (doesnt go lower than -m700 at all!)

only the -v option i havent figured out yet. if someone can give me a working number, please? so far i have tried 900, 950, 975, 1000, 1050, 1075.

still stays at 1100.

also, if someone knows a working -m lower than, please kick it my way!


i dig the program. nice work!

[mike85123]

it is normal for the speeds to jump if you start mining - the card is switching from lazy powersafing 2d mode to hard work 3d mode. the problem is that the high values should stay to what you put them.

According to GPU-Z, the Graphics Card tab says Clock is 1000 and Mem is 300, but the sensor tab shows Clock @ 1000 and Mem @ 1050. Ever seen it show two different values?

Can someone with a 4 card 68XX setup check to make sure everything is working properly? I just tried ClockTweak on a 1 card setup and it seemed to set everything right.  I am starting to think that similar to how Afterburner doesn't work on a 4 card setup, maybe ClockTweak isn't working too.

if the card was idle it is normal to show different values. was it? also it might take some time to refresh.

ClockTweak is working fine with a four card setup, I have four cards myself and lots of other people have confirmed it.

Still there seems to be something weird going on with your system. Please do this to help me debug:

Reboot your system
do not start any miners yet
run "clocktweak -r -l"
run with your parameters: "clocktweak.exe -a all -c1000 -m300 -v1000 -s95 -y"
run "clocktweak -r -l"
start your miners on two cards
run "clocktweak -r -l"

post all the outputs here in a code tag as before.

other things you can try:
with cards in idle and all cooled down set fan speeds of single cards high to determine adapter# for each physical card. also take a look at gpu-z so you know the order in gpu-z. you may want to write it down (I did =) ).

start a single miner on a single card and check with clocktweak / gpu-z which cards gets hot to determine gpu/adapter# for your mining software.

with the miners running change clock / mem speeds of single cards and check if hashrates change.

When mining on 2 of the GPUs, GPUZ is reporting that the GPUs that are NOT mining are running 300 & 300 and the GPUs that are mining are running 980 & 1050. If I change Clock speed, the MH/s do change but from the beginning it always looked like clock and fan speed worked & voltage and memory speed didn't.

[phelix]

please upgrade to the latest version. there is a patch at http://bitcoinx.com/clocktweak

v0.8.0b displays a wrong coreL0 clock speed (coreL2 instead)


still it is kinda awkward that your memL0 and memL2 speed are both at 300. that should not be possible. I assume you did not make a reboot before these readouts. try a memclock of 303 instead of 300. it looks like 300 is your bios limit.

I had tried it in 0.9 already and dropped it back to see if the new version caused the problem. GPU-Z is still showing the same results as my last post.

[2weiX]

I repeat my question:

Does anyone have a working number for Sapphire 6950 1GB voltage?
Shipped with 1.1v, GPU ist 840, memory downclocked to 800.

Would LOVE to set the voltage a little lower. Anyone?

what driver version do you use? it seems to accept clock speed levels out of order.

if you like you can try the hidden options (mentioned in the readme)  -memlevelX  and -corelevelX 

you can try this procedure:

clocktweak -y -a all -m 280 -memlevel0
clocktweak -y -a all -m 290 -memlevel1
clocktweak -y -a all -m 300 -l

[Lexiko]

Made a simple auto temperature control .bat script using ClockTweak tool http://forum.bitcoin.org/index.php?topic=28319.0

It can to control gpu core temperature by changing core speed depends on Minumum and Maximum margin values.

P.S. phelix, I made it my own way, so last features with errorlevel were not useful

P.P.S. phelix, don't you want to compile linux version of clocktweak?  Now it is more functional than other linux tools.

[Jabba]

To get other voltages you just need to get a copy of your bios by using GPU-Z.
Then take RBE Bios editor and check the different states for their clock and voltage. Voilá there you go. Take the next lower voltage setting and start tweaking - big fun!

So now that you've got JSON implemented, I think I'll start work on some monitoring software based on clocktweak

I bashed something together for myself but it's very hackish, nothing trapped for or commented, messy code and bashed together in the quickest language I knew (Classic ASP).

It's up at http://codinginmysleep.com/miners/ for critique. Pretty basic interface, color-coded HUD at the top for each miner and the simple clocktweak -r -n output below. Not pretty but it functions. Would anyone be interested in something of this nature?

But u didn't need a json . I'am doing in such way:

Code:

echo off
SET Miner=Miner1
FOR /F "tokens=1,3,5 delims=:# " %%A IN ('c:\windows\clocktweak.exe -r ^| Find "Temp"') DO (
wget "http://myserver.com/bitgraph/collector.php?MinerName=%MINER%&Temp=%%B&CardId=%%A&Load=%%C" 
)

It will do GET request for each gpu installed something like this:

Code:

http://myserver.com/bitgraph/collector.php?MinerName=Miner1&Temp=76&CardId=0&Load=98"
http://myserver.com/bitgraph/collector.php?MinerName=Miner1&Temp=73&CardId=3&Load=98"

nice work! an advantage of doing it your way instead of using the errorlevel method is that you can control each gpu separately. I am still a bit sceptical about the sweet spot / clock vs hashrate linearity issue. I hope to find time to build a sweet spot scanner soon.

Maybe there is another way to throttle the gpu - e.g. by slowing down a cpu core by issuing HLT commands or by somehow slowing down the gpu (powertune is perfect but only available on 6xxx cards).

I will think about a linux version - unfortunately my experience with linux is limited.

Classic ASP?  Python rulez!

I like the color coding.

p.s. could it be that some of your cards are a little lazy? Mine have to work hard at 99% load all the time.
