If you need any help in translating your pool into russian feel free to PM)))

I do want it to be true.

But I have to fans down

'cause I have 2 examples of my own and claims of far more experienced people than me.

EAH5870  - dead fan (does not spin more than 700 ~rpm even if hardware forced)
GV-R587 - one fan is down the other is hardly spinning.

Perfect reply!!!

Mooving to Linux)

What Linux are you using?

Yes, still profitable.

Did you play with mem frequency?

76C is ok. Any method to monitor vrm temps?
Do not force your GPU fans to spin at 100% or they will die in a month or 2 of 24\7.

My pleasure)))

Do you use modified kernel?
Phatk or what?
Try to boost your mem to 360-365. It added me a couple of MH\s.

try to set max priority for your miner.

Use MSI AB for oveclocking.

30USD

applying thermal grease is very easy!
It helped me to reach 3-5 lower temp on my 5870 cards.
I used AC MX-4.

try phoenix + phatk

Had 6950 with no problems while mining and playing video from youtube.

Used these flags:
-k phatk DEVICE=0 VECTORS BFI_INT FASTLOOP=false WORKSIZE=256 AGGRESSION=13

The best for you would be:

Catalyst 11.6

http://sites.amd.com/us/game/downloads/Pages/downloads.aspx

SDK 2.4 (phatk is optimized for this version)

http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx

Phoenix + Phatk miner

Configure for desired pool using these flags:
-k phatk DEVICE=0 VECTORS BFI_INT FASTLOOP=false WORKSIZE=256 AGGRESSION=13

Than download this:

http://github.com/downloads/m0mchil/poclbm/poclbm_py2exe_20110627.7z

and unpack the phatk.cl to to your kernels folder naming it kernel.cl (or whatever the name is there in that folder. The initial kernel file has to be overwritten)
this manipulation will boost your performance up to 3%

Overclock your device to 970 core and underclock memory to 362-365 (needs testing) and I guarantee you will beat 439 MH\s!

Good luck!

My setup is the same as yours! The only thing is I use Windows 7 SP1 x64!
My rig generates 1720 MH\s with 970 core and 365 mem with stock voltage.
Another advice:
Keep your temps below 80C and do not force fans to spin 100% 'cause you risk to get the fans down in approximately a month of 24\7 hashing and as a result you get burned GPUs!

Any questions? Feel free to PM!

GuiMiner (easy to configure)

http://forum.bitcoin.org/?topic=3878.0

Create phoenix miner in GuiMiner, configure for desired pool using these flags:
-k phatk DEVICE=0 VECTORS BFI_INT FASTLOOP=false WORKSIZE=256 AGGRESSION=13

Than download this:

http://github.com/downloads/m0mchil/poclbm/poclbm_py2exe_20110627.7z

and unpack the phatk.cl to guiminer\kernels\phatk naming it kernel.cl
this manipulation will boost your performance up to 3%

Overclock your device to 1000 core and underclock memory to ~300-365 (needs testing) and I guarantee you will beat 310 MH\s!

Good luck!

Any questions? Feel free to PM!

What case and fans do you use? Their placement?

Please tell all the details.

5870

970\365

430,5 -> 439,4 ~2.07%

W7x64 SP1, Phoenix 1.5 + Phatk, APP 2.4, Catalyst 11.6

 

THANX A LOT

It may have been better if I removed that piece of plastic with its tiny fans from my GV-R587 cards and put Ultra Kazes on each...

Will do so if my cards will return from the reseller in shape)

a month or so

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

How did you manage to cool them that well?

so what should I do when get new cards?

Keep them around 65C with no 100% fan and no everclocking?

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?
