It was really cool to have:
1.) a sweetspot finder
2.) artefact and temperature limited overclocking control = permanent optimization

I thought about these functions quite a bit but it would take a lot of time to implement.

While artefact and sweetspot would be harder to implement, a looping display of the -r output, with the possibility of increasing fan/reducing overclock depending on temperature would be very useful; would also be a pain in the backside to code via scraping output.

Thanks for a super utility, well worth the price paid. 

the problem is that the hashrate over clock is quite nonlinear. I am quite certain that in some cases slightly lower clockrate increased temperature on my system and that lower core clockrate sometimes results in  higher hashrate. This topic needs a lot of investigation...

Hi!

There is a problem with my HD 5870 V2 and I hope you guys wil help me.

I have 4 cards in a rig 3xGiabyte 5870 and one HD 5870 V2. Generally I run them 3x960\365 and 990\365\1.3v and set those parameters via clocktweak. Everything runs fine BUT then something happens and the fan of HD 5870 V2 suddenly lowers rpm to ~700 though in AB its shown that it is 100%. Clocktweak shows that it is only 15% of its max speed.

Afetr this I can not tweak the card via clocktweak. It says me ERROR: write_values: xxxxxxxxxx whatever I do.
But I can tweak a card via AB for example though fan still spins at ~700 rpm while displayed as 100% in AB.

All the cards are crossfired.

How to overcome this whatever it is?

[RedLine888]

This happened to another card

One of Gigabyte cards now. Fan spins at ~1500 rpm while max is ~3500.

WTF is happening...

Help please.

[hawks5999]

are you running clocktweak and AB at the same time? You'll need to exit AB before using clocktweak.

[RedLine888]

I run clocktweak 1st, set parameters, close it and open AB. AB does not set its parameters at opening. I use it for t monitoring.

[phelix]

at what temperatures do you run your cards? downthrottling because of overtemp? could also be a bad fan bearing. is the load also going down?

[RedLine888]

The load stays perfect 99-100%
Tried cards one by one and everything works only when all together problems start. My OS is W7x64 SP1 soft for fan control is MSI AB (also tried Asus SmartDoc, GPU clock tool, etc.), even Asus smartDoc refuses to detect the card when its crossfired with others! Should I use dummies?

That doesn't make sense at all, I can see why you're having problems...

I have only experienced something like you describe (fan going slow even when set to 100%, sometimes working again) with a broken fan (probably it was not the bearing but something else).

watch your temperatures, if the fan stops or goes that slow you can blow your card!

[RedLine888]

Looks like it is dead(

Tried all the combinations even removing the blue wire as advised above but did not succeed in the end!

RIP!

Tomorrow will give it back by warranty terms.

By the way! Something may have happend suddenly 'cause I started to have problems today in the morning and now its evening in my country and I have 3x5870 which refuse to work properly though everything was fine yesterday!

One is EAH5870 V2 which has 700rpm fan problem.
And two GV-R587 one of which boots up till "Startnig Windows" and then I can hear welcome sound bit the picture hangs on "Startnig Windows" screen! The other just makes my PC hang on boot!

Now my rig mines with a single GV-R587 which I hope will live long life...

A bad day I have today(((

Are there any opinions on what may have happened to them?

[hawks5999]

The sun killed your card I think:

Did you do something to anger the sun?

[RedLine888]

It may have gone angry with me 'cause I sacrificed one of my 5870s to BTC God

Will go and and burn a coulpe of my 75 Ohm resistors in a name of SUN to huggle it so my single 5870 that has left would outperform itself to 10 GH\s

I would like to undervoltage my Saphire xtreme 5830 card since because of the summer heat I run at a lower core speed. Trixx let me reduce the voltage only to 1.163 V  . Can anyone with a 5830 please test, whether ClockTweak is able to reduce the voltage further?

it will probably only work in a handful of big steps. if you buy and it should not work I will give you a reeefund.

[Jazkal]

It would also be interesting to have it exit with unique errorlevels if the gpu load drops for too long (e.g. --> restart phoenix) or if temperature would rise above a maximum level (--> shut down).

How much interest would there be for such features?

Yes please, these would be great to enhance scripting in logic.

I have a question about this command: clocktweak.exe -a0 -c950 -m325 -s100 -y

When I run that I get 320 Mh/s, but when I run the ATI tray overclock with same settings, plus power +20%, I get 420 Mh/s.

So my question is, how do I set that +20% power via command line?

[hawks5999]

-v sets power. You'll have to do the math on what 20% would equal.

[enmaku]

Thinking of doing something bigger with this and while I'm certainly competent enough to parse your output I have to ask anyway... Any chance you could add another flag to give the -r output in JSON?

thanks for sharing!

it seems on the 5770 fan control never works. or did it for anyone?
