clocktweak doesn't let me clock my XFX HD5870 (link) above 900Mhz.

I could however overclock above 900 using the AMD tool (link), so it's not a hardware restriction, and I'm now using that tool instead... Sad

Here is my clocktweak -x

Code:

I bought this just for the ease of adjusting mem to 300 on all cards.

However, do you know how amd gpu tool get to raise core clock higher than bios allows? I would love to use this clocktweak program to adjust more than just one cards above bios limit.

care to explain more ?
It is still in beta phase, so please help testing. You will get a full refund if you are the first to test ClockTweak to change clock/mem speeds and reduce voltage in one of the following environments and post a copy of the outputs of the "-x" option here. Please include information about the type and manufacturer of your card(s)!
I guess I have to add it's sapphire 5830, xtreme

still waiting for payment.

Hi, received the app and it works great.  

EDIT: Summary of tests, all were able to underclock memory to 300mhz.
XFX HD5850 Win7 64bit,  -v range is 951 to 1100 in steps of 1
HIS HD5770 WinXP 32bit,  no voltage control, fan speed reports unknown
Sapphire HD5750 Win7 64bit, -v appears in to be steps of 1, did not test full range.

Would like two feature requests:

1) ability to control fan speed from command line.  This way I can script idle/mining/gaming and control temps a little better.
2) bare format (suppress program name and version) that shows date/time and all adapter details in one line, would like to be able to run this every 5 mins and dump to a text file for logging/monitoring

XFX HD5850, 2 monitors attached, Win7 64bit

Working fine on my Crossfire 5770's. MSI Hawk and XFX respectively. If you got that PM I sent earlier, well, it was a bios wall I was hitting on the XFX card. Flashing a new Bios solved the problem..

I bought this just for the ease of adjusting mem to 300 on all cards.

However, do you know how amd gpu tool get to raise core clock higher than bios allows? I would love to use this clocktweak program to adjust more than just one cards above bios limit.
low level hardware access bypassing the driver would be necessary. Also there are different voltage regulators that the manufacturers use. I would look into it for the Sapphire HD 5850 Xtreme Rev 2 as I have a couple of these cards myself but it is difficult to even get the chip specification...

btw is there any way to make the changes permanent ?
what do you mean by permanent?

you can write a batch file and put a link to it in the autostart folder so that it runs at every startup. put each call to clocktweak into its own line and maybe add a "pause" command on the last line so that you can read the results.

Afterburner is able to set my clocks to 950 but I'm getting the error above with clocktweak.
Would love to have this work, but if not:

With ClockTweak I'm seemingly able to underlock my Radeon HD 6990's memory all the way down to 1 MHz. Reading back, the same value comes out. I kind of doubt that the hardware actually supports running at 1 MHz Commodore 64 speed though... And I don't seem to get any noticeable temperature drop either. So how do I find out how much I can REALLY underclock. MSI Afterburner let me go to only ca. 100 to 120 MHz below core speed (exact number depended on core speed), below that the display would show the stock 1250 MHz again. Still I got no temperature drop to speak of... and I've seen other people talk about underclocking to 300 MHz or even to 159 MHz.

So... how do I find out how low I can actually go? Or does anybody around here know how low you can clock a 6990?

My System: Windows 7 SP1 64-bit (fairly fresh installation but with all Windows Updates applied), Core2Quad 2.83 GHz,  one HD 6990, Catalyst 11.6, Phoenix miner (SVN version 103) running from source on 64-bit Python 2.7.2.

Thank you for any help!

1Mhz - LOL. If clocktweak does not complain and can even read it back it means the driver accepted it. But it seems the

What happened to the hashrate?

did you try to check with another tool like GPU-Z?

hi,

I am running three VGA Sapphire Radeon HD 6950, 1GB GDDR5 (non-reference,obv).
I've been able to overclock the GPUs to 840 and am getting 330mHash/s with a couple of flags I cannot replicate from the top of my head AND a fan angled at the cards from zero distance, temp is ~75C.

I was, however, to this point NOT able to downclock the memory. I tried Afterburner, Trixx, BarelyClocked... nothing.

In your introductory post it says that the 6950 is supported. Might my model be an exception?
If you think your little prog could make this work, I'd love to buy it.

I am optimistic it will work. otherwise refund.

I have two 5830 saphire extremes. 

1) Can only OC one card, either with "-a all" or specifically putting the adapter and using -f
2) Can't OC past 900mhz.   MSI afterburner allows this.

Please help?

I wish someone would make a similar tool for Ubuntu. At least a tool for overvolting.

My command line knowledge is rusty so forgive me but am getting these errors when running:

Traceback (most recent call last):
File "C:\Python26\lib\site-packages\py2exe\boot_common.py", line 92, in <module>
ImportError: No module named linecache
Traceback (most recent call last):
ImportError: No module named zipextimporter
Traceback (most recent call last):
File "clocktweak.py", line 15, in <module>
ImportError: No module named argparse

Please advise.
what system are you running on? do you have python installed?
