Do you have the 5850 xtremes?
If you do and you make the tool able to Overvolt all the cards I would gladly buy this (Sapphire TRIXX only allows you to overvolt ur first card)

yes

did you check that with gpu-z or something? my trixx does not really change anything besides the fancy scrollbar (actual voltage stayed the same) when I last checked.

[Beremat]

Works well! I think I'm the first one to change clocks and undervolt on a 5870, so if you can, refund me at 1EavXbWqAYWPQK7VXjgSvuVL5YiHCga5ni. If I'm not the first, then ignore this

Sadly, it doesn't let me set any core clocks or voltages above default. I get:

Set values - starting.
 Adapter 0:
  setting voltage 1170 [mV]
  write_values: ERROR setting voltage 1170 (1)

[justinjja]

Glitch with gpu-z i believe,
when i raise the voltage
 
1 my temps go up
2 wattage goes up acording to my killawatt
3 my 950mhz overclock becomes stable
4 gpuz stays the same.

what type is your other card? did you try to change something on that, too?

BIOS voltage limit is expected. to increase the core clock you will still need RBE. I am looking for a solution to this but it probably will not work via the driver.

ok, that really sounds like it's working. It still should only work in steps becaues of the VRM (see post from Ius). I will check with the watt-meter, too.

It's a pitty AMD is so restrictive about voltage control - either they are afraid of people bricking their cards or they want to sell more expensive ones.

Just wanted to plug this little tool.  It's perfect for Windows dedicated miners so that you don't have to mess around in a GUI to adjust clocks/memory/voltages etc.  Very helpful, and totally worth it.

can this change voltages on non reference cards?

[phelix]

can this change voltages on non reference cards?

you will probably only be able to reduce voltage. on my sapphire HD 5850s voltage changes are quite limited, basically the only option that makes sense is to reduce voltage to 1038mV to save power / lower heat.

if your manufacturer is among the ones not yet tested you will get a refund anyway.

[phelix]

Lowered the price. Bitcoin is rising fast...

Doesn't let me run my Sapphire 5850 Xtreme memory under 301MHz, are you using a stock bios?

Can I use one copy of ClockTweak on all my desktops?

just go ahead and donate another 0.1BTC per GHash/s above the first 1.5GHash/s if you like it.

yes, I am. please send me the output of -x by pm. I know what's going on and should be able to fix it. That is quite unexpected, especially with that card - do you know the revision number? What colour is the circuit board?

[phelix]

new version out: 0.7.4b
update patch available at http://bitcoinx.com/clocktweak

will downclock memory more aggressively

Zzzoom please try it.

[Lexiko]

Memory underclock to 300 mhz works great on my 5850, 6850 and 5770 (Asus, Gigabyte , Saphire, His) under Windows 7 x64 Professional/Home, Server 2008 x64, Windows XP x32 OSes.

Thx a lot, wait for more donate and wish you luck in the further development.

Yup, it works now. Thanks.

edit,
it seems to work fine.. now can any suggest what values I'd like to be aiming for - as I've managed to make it run a lot cooler now.... but suggestions on what I should be really aiming for whould help

[phelix]

sent the refund!

what are the brands of your cards?


a value of thumb is to set the memory clock to a third of the core clock. and the core clock as high as thermally stable at current voltage.

some people say there is are sweet spots, configurations that work better than others just a Mhz away and stay particularly cool. I have not yet decided on this.
