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)

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.

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)

The VRM output voltage for HD5800 series cards (ie. VT1165 VRM) can only be set in steps of 0.0125 V above a minimum of 0.450 V, if I'm not mistaken.

experimenting with the wattmeter, I just noticed that though my cards happily accept all voltage values the voltage regulator has only a couple of steps... will investigate some more and keep you posted.

you should be able to set the mem clock down to 159

Does this let me lower my mem clock on a saphire HD5850 to 300? I can do this with the Trixx utility, but not with the ATI Control Panel.

phelix, ygpm

I found that ATT would only work for one card, so I use it on the XP box which has only 1 card (don't be misled by the clocktweak output - the machine has 1 card with 2 monitors) I only use it to set the clocks, I never bothered with the tweaks simply because I am too lazy to spend time messing with it - "If it isn't broken, don't fix it". It is convenient because it can run at startup without human intervention. The XP machine is my desktop, and tends to need occasional reboots. I stick with XP on this because there is a game I like to play that I have not been able to get working correctly on Win7.

AMD GPU Clock Tool allows more cards. It works for me on a machine with 4 HD5870s, but I have not been able to use it to set voltages. It does have the useful ability to log temperatures to a file. The version I have is 0.9.26.0 and I have no idea whether it is up to date or not. I can't remember where I downloaded it, but it turns up in quite a few places with a Google search.
My 4 dedicated mining machines run Win7 which seems to be stable enough that the irritation of having to set clocks manually on a reboot isn't that great. (1 reboot in 3 months, caused by power failure)

I am hoping that clocktweak will allow me to set voltages. I will experiment this evening when I am at hope. I am too much of a coward to try setting voltages remotely in case a do something that needs a hard reboot to recover - VNC has its limits.

With difficulty rising, it may be that the last few Bitcents can be mined by underclocking and undervoltaging the cards to reduce power use and improve hashes per Watt.

I'm really digging this tool, BTW.  Easy and no GUI fuss.  Thanks.  This'll definitely be my preferred method of tweaking once you fix the dual GPU issue.

thank you guys! I send you both the refunds.

@cdb000
these are very interesting programs. until now I had never found ATT and only an older version of the GPU Tool.
ATT I can only get work with one card, the same as with a lot of other programs. Do you use any of the tweak options for mining?
The GPU tool seems to be really sophisticated I will take a close look at what it can do.

@proudhon
Seems like you found the first problem already. it applies to dual gpu cards like the 5970 and the 6990. I will look into it.

So, it looks like changes are only being applied to one of the GPU cores of my 6990.  I wondered if that would be the case when I saw that it reported only a single adapter, as you can see in my screenshot above.

OS: Windows 7x64
Manufacturer: HIS
Card: 6990
Setup: Single Monitor

Clocks were set with AMD's utility, but I going to start messing around using ClockTweak.  I've never bothered lowering my memory clocks, so I'll let you know how it goes.

I became interested in your program because I wanted to up voltage. I care about increasing MHhas/s, and the same 930/300, I managed to get the program AMD ATI Tool.

Now I use ClockTweak using batch - the PC always starts with the proper performance

Today evening I will try to test the program with the Sapphire HD5830.

The following captured on 32 bit WinXP with a single Sapphire HD5870, 2 monitors attached.
Clocks were not set using clocktweak, I use ATT Tray Tools for this.

Thank you for your tests! I send you back your 0.4BTC.

could you also post the adapter list, output of clocktweak -a

your card is already at the voltage limit from the bios. I realize with most cards it will only be possible to undervolt without modifying the bios - I will edit the description. you should be able to set the voltage to 1117mV for example - but try it at a lower clock speed first.

the advantage of a lower voltage is less power consumption and also less heat.


still you should be able to overclock quite a bit and remain stable.

I think your card comes at 725MHz core / 1000Mhz mem stock clocks? so with 930Mhz you overclocked the core quite a bit and 300Mhz mem clock also sounds good for mining.

I use your program, unfortunately I can not change the voltage on any GPU.
I have 2pcs Asus EAH5850 DirectCU TOP/2DIS/1GD5, Win7 64-bit


What's wrong?

http://img197.imageshack.us/img197/1558/clocktweak.png

I tested Catalyst Control Center and overdrive options, none of them raised voltage on my 6950 DC II. MSI Afterburner is unable to change it.

yes it should work. On my HD5850 I can drag down the Memory Clock all the way to 159Mhz.


I will give refunds if ClockTweak does not work as advertised, at least for people with some reputation on the forum.

I have asus 6950 DC II which has quite unique voltage control(only the program that asus provides has worked so far). Does your program work for it?
