Yeah I didn't *need* JSON but it sure makes things easier to have it

also safer.

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?

please post the output of -r -l

which driver version do you use?

clocktweak output:


driver version 8.850.0.0 (4/19/2011)
catalyst 11.6

you can do as Jabba suggested and use RBE to find out your valid Voltage levels. Probably the next lower level is 1000mV. If you try to set that clocktweak will happily accept it but nothing happens? I have an Idea of what happens. Unfortunately it will probably not work on your system with the current clocktweak strategy. Maybe I have to rewrite the voltage setting part a little.

Are you aware that you will 99% not be able to run 840Mhz at a lower voltage level?

Did you set your level1 memclocks (699 / 799) manually?

I've never touched any level1 thingies (knowingly).

I've added the GPUObserver Widget and it seems that one of the programs gets it wrong.

with -c840 -m800 -v1000, clocktweak nicely shows CoreL2:840 MemL2:800 mVoltL2:1000
However, GPUObserver shows 840MHz Core, 1250MHz Mem and 1.10V

seems funny that all of a sudden i shouldnt be able to change the memclock. it DID work yesterday. I have since updated from catalyst 11.5 to 11.6, might this be a problem? hashrates are fine and all, however one of the card is at 81C now witht the fan at 100% while the others are at 65C.

I would suggest GPU-Z for checking, I think it is very reliable.

-y -a all -m 200 -memlevel0
-y -a all -m 300 -memlevel1
-y -a all -m 800

works like a charm.
i guess the BIOS keeps me from going below 800. still shaves a cool 4°C off every card.
if you find a way to enable me to set the memclock to 50/100/200 or so, that'd ba brilliant.
not sure if i still want to try to undervolt the cards unless you find a way to severely underclock the memory.

It is a known bug on systems other than Win XP, just ignore it. It doesn't affect anything.

6870 - XFX (http://xfxforce.com/en-us/products/graphiccards/hd%206000series/6870.aspx?product=29192)

I'm able to set a memclock of 300 and have it read back as 300 in clocktweak, but the card is likely still running at stock 1050. i can't underclock the memory at all in afterburner and CCC. hashrates are the same.

Hi Folks,

reagrding the throttling of the GPU there's a much easier solution available.
I remember that there's a switch for the miners like your -v -w128 switch which tells the GPU to slow down.

I just cannot find the thread where it was discussed.
By adding this switch to a command center (that's where all your efforts and ideas lead to) handling would be improved a lot.

BTW: ever thought of managing all mining rigs and their cards from a single console?

Cheers

Lowering aggresion comes to mind. The only problem with that is that you have to stop and restart the miner.

[Jabba]

'Lowering aggresion comes to mind. The only problem with that is that you have to stop and restart the miner.'

Which can also be done via commandline - so this should be no big issue.

There are three sets of clock speeds:
Level0: 2D
Level1: intermediate - limits?
Level2: 3D

The levels can not be the same, there has to be a gap of ~10Mhz or so. Level 1 has to be in between level 0 and level 2.

With -r -l  you can read out all clock speed levels. Depending on these you can determine mem clock values to try. Level0 may or may not be the lower limit.

You could try with these hidden options if your mem clock speed level 1 is higher than your desired mem clock speed level 2:

-y -a all -m 200 -memlevel0
(only necessary if memlevel0 clock it is lower than your desired memlevel2 clock)
raise the value if you get an error (Bios limit!)

-y -a all -m 302 -memlevel1
has to be above level0 and below the level2 clock speed you want to set

-y -a all -m 330
changes level2 (= default target)


I hope it helps. For most cards ClockTweak will do this automatically but there seems to be an issue with some of the 6xxx cards and/or latest drivers. I will redo this for the next release.

You can try my gpu core auto control script, based on clocktweak http://forum.bitcoin.org/index.php?topic=28319.0 .
I'm testing it now, and see that this works great! In plans to manage aggression the same way, but there is the same with gpu core trottling.

BTW: ever thought of managing all mining rigs and their cards from a single console?

For what? I think it must be only monitoring dashboard, rigs must work automatically.

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...

Here is my clocktweak -x

That was it. After using -r -l to see m0 is already at 750 and m1 at 1050, I used -y -a all -m 800 -memlevel1. At that point I can use afterburner to change all the way down to 300. I think with memlevel1 at 1050 it was stuck at 1050.

Hashing rates don't see any improvement but there is a noticeable temp drop. Do voltages have the same level0, level1 restriction? I have level2 voltage set lower than both level0 and level1.

Also noticed a small bug:
  -v VOLTAGE, --voltage VOLTAGE
                        Set voltage for level 2 [mV]. Example: -c 1050

- i`ve tried with and without miners
- i`ve tried with and without prior overclock (using TriXX)

i`m using Sapphire Trixx to overclock for now

all my systems are running Win7 Ent x64

seems it doesn`t work for me

Card Types
HD5670 - tested (RaTTuS)
HD5750 - tested (SteveFL)
HD5770 - tested, probably no fan control (Raigekisai)
HD5830 - tested (grue)
HD5850 - tested (phelix)
HD5870 - tested (Beremat)
HD5970 -
HD6850 - tested (ujin)
HD6870 - tested, limited functionality with v0.9.0b? (mike85123, OCedHrt)
HD6950 - tested (coznefx)
HD6970 - tested (Jazkal)
HD6990 - tested (proudhon - thanks a lot for your support!)

I'm in the process of testing this for a Win7x64 system running 4x6770 (Sapphire).  Everything seems to work fine except the program will not detect the fan speed of the cards (reports N/A), nor allow me to set the fan speed.  This is peculiar as I can set and monitor fan speeds with the ATI Catalyst and MSI Afterburner tools.

I'll post program output later today as I am not at the computer with the hardware right now.

Just to let the boss know how it works right now:

On my 6950s (1GB non-flashable), i need to adress -memlevel0 and -memlevel1 separately on every card. the -a all doesnt work (ie it would "work", but then -m 800 would show no effect and the memspeed would go back to 1250).

So the procedure is
- change memlevel 0 for every card
- change memevel 1 for every card
- change the memlevel 2 for all the cards
- change the corelevel2 and the fanspeeds for all the cards


any other way, it don't work, for whatever reason.
i am, however, greatly satisfied. this is just to maybe put you on the trail of some minor edges that need to be trimmed off^^

thanks for the info! I will check if there is any difference in setting levels 0 and 1 via "all" or separately but I can not think of anything at the moment.

Here is a quick output dump showing the functionality working with a Sapphire 6770, albeit no fan control or speed reporting.  I've been able to change multiple GPU properties in the 4x6770 system, but I'll only show the dump for one.  If eligible, you may send the testing credit to 1BrcSXF3te8YNvfwDp9yoFebvZNkxGRe7i.

Finally got the voltage changing to work altho it still wont work with any other app.
Had to remove all the drivers then install 10.12 then updated to 11.5
Just going straight to 11.5 wouldnt work no changes would take effect. And 11.6 doesnt work ether way and kills my Mhash speed.


Also noticed that in the help there a small error. Says to change voltage then the example has -c instead of -v.
