That's what you get for your mantra to Jiggly Puff....

Nothing for Sri Ganapati or Lakshmi Maa?

I'm on St. Eligius and that's Catholic.... but I don't know any depressing Catholic hymns....

Are you using AMDOverDriveCtrl and leaving it running?

On the 58xx series, it drops the memory clock floor to 150 (at least, it does on 5850s and 5870s that I've had).

It's easier to go with

aticonfig --odsc XXX,XXX

Your memory clocks seem awfully high - you can't set them any lower?

You might want to re-evaluate pool vs solo before being so definitive.

You can set up a single instance of the official bitcoin client and then point all of your miners at it the same way you would a pool.  They can all use the same username/password.

Be warned - the official client, any user with a valid log in can use the getwork command to hash for you.  Unfortunately, they can also use all the other commands (such as emptying your wallet), too.

So be careful if all of those machines aren't on-site.

Is your name a Fallout reference?  Or do you actually live in Oregon...

I just planned to Craigslist my gear as "ATI Radeon 5850 - Only one month old!  BIOS flashed and overclocked! - $335"

Expect that a lot here.....  I think, in order, the top 3 things I read are:
#1 Killowatt to hash ratio is bad!
#2 You'll get fired and sued for mining bitcoins!
#3 CPU hashing is inefficient!

On the PCs I (ab)use, I just set up scheduled tasks to run after 10P and kill any miners before 8A.

Anyone suggesting that it's "impossible" to get the same numbers in Linux as they get in Windows....

.... is correct.  Linux numbers are much higher.

People have done an exceptional job of providing the answers - just use RBE.  AMDOverDriveCtrl doesn't give me problems on my cards.  Driver version is a definite possibility - anyone with any Linux experience should know that *generally* the drivers for Linux are much lower quality.  Whether they just be outright buggy or the installation is torture, they just simply aren't the same quality as Windows counterparts.

Here's a case study for you -

Several Diamond 5850s (non-reference, no voltage adjustments possible)
Flashed with FreeDOS to edited BIOS from RBE
Watchdog hardware module
100% unattended boot to init 3, xinit, AMDOverDriveCtrl profile load, miner startup
8 second boot time
Can't clock over 1005 MHz CPU without causing a kernel panic/hard reset
Manageable with screen/ssh
Catalyst 2.4
HAL independent - clonable to any machine
394 MHs on average with phoenix/phatk and aggression > 15.

*Exact* same card in Windows 7x32
Flashed same way (same card - did a "burn in" test in Linux before transferring it to Windows)
No watchdog.
Autologon + startup script for miner
37 second boot time
Can't clock over 925 MHz CPU without causing a driver fail, machine reset or poclbm/phoenix hanging
Aero turned off (no idea if this makes a difference....)
Manageable with.... VNC or garbage RDP
Catalyst 2.4
HAL dependent - lengthy install required
310 MHs on average with phoenix/phatk and aggression < 13 (otherwise it hangs)

If any Windows Pros want to tell me how to fix the Windows machine - fire away.

Also - what tool lets you set profiles and load them in a script like AMDOverDriveCtrl ?

PS - Fedora x32 and Fedora x64.  Miners aren't worth RHEL licenses.

Right.  From 292 to 392 MH is dumb.  A 100MHs gain is for people that are broke and can spare the 10 minutes it takes to overclock.

My current GPU temperature?  72C....

I'm not sure if you're trolling or trying to justify to yourself the "silliness" of doing something you refuse to do.

I've been overclocking since Cyrix made those 486 booster chips.  I think I've had one single piece of equipment loss - and that was an Intel.

Quick update -

Moved to phoenix with phatk and now running at 395 MHs.

I use an init.d script with -

xinit -e metacity
export DISPLAY=0:0
sleep 3
xterm &
xterm &
AMDOverDriveCtrl &
aticonfig --odsc 1005,225
aticonfig --odcc
xterm & -e bash --rcfile startpoclbm.sh

.... I like metacity.  Feel free to replace with whatever you want.

I could also probably remove the AMDOverDriveCtrl + aticonfig x 2 line and just use an AMDOverDriveCtrl profile...

But I didn't.


As far as a "watchdog" feature built into poclbm - it's in Python.  Build your own.  Something even as simple as echoing out the current time to a file, then have a second script kill/reset poclbm/pheonix if the time is > 5 minutes or something.

My miners don't lock up.  Unless I'm effing with aticonfig.

Well, here's my story about Diamond 5850s and a buddy of mine....

So you know what I did for mine and what's running at.  My buddy, in the mean time, uses Win7x32 with the same BIOS change I did.  The cards have identical SKU and models, etc, etc except the cards I bought (out of the box) had a ceiling of 775 while his was 825.

We followed the same steps I did and he's having trouble keeping his card running over 950MHz.  Either poclbm locks up, the PC locks up or the whole damn thing resets.

Now, obviously, this is a single case-study type of situation, so I didn't want to definitively declares "Linux is WINRAR!" because of this possible "fluke," but that's the story so far.

Not sure how to do it with RBE, but you can save an AMDOverDriveCtrl profile with the voltage adjustment and reload it on startup... I think...?

The cards I had access to were all Diamonds - no voltage control for me.

aticonfig, AMDOverDriveCtrl, flashed BIOS with the ceiling set to 1200 (uh, it seemed like a good number at the time....).

Oh, and poclbm -v -w128 per the mining comparison chart.

Edit:

Here's exactly what I did... so I don't have to type it again...

+1 to "whichever you're most comfortable with."

Most of my boxes are Fedora.

As far as "overclocking being less powerful" - I have no idea where you get that idea.

I've got Diamond 5850s running at 1010 GPU clock, 300 memory clock for 380 MHs.

Because they're risky and easy to cheat?

There are already dozens out there.

Here's my way -

1) Go get unetbootin - http://unetbootin.sourceforge.net/
2) Use it to create a FreeDOS bootable thumb drive.
3) Go get atiflash.exe (google for it).  Put it on the thumb drive.
4) Boot the thumb drive.
5) head to C:, type "atiflash -s 0 mybios.bin"
6) Wait until that finishes, reboot
7) Go run Radeon Bios Editor  http://www.techpowerup.com/rbe/ notice that there's a link to a tutorial...
Here's a link to the RBE tutorial about "Additional Features" http://www.techpowerup.com/articles//overclocking/vidcard/154/7
9) Change the "Method 2" numbers for your CPU ceiling to something ridiculous - like 1100
10) Save your changes to newbios.bin and put it on the thumbdrive.
11) Boot FreeDOS again.
12) atiflash -p 0 newbios.bin
13) Boot linux, type "aticonfig --odgc" and see if your maximum is what you entered in RBE.

Sounds like you're on the right track!

Good luck!

Use Radeon BIOS Editor with your currently working BIOS.

On the far right tab of RBE, there's an "Additional Settings" or something that has a "Method 1 - Hash" and "Method 2 - Not likely to work."

Use the setting above (the method 2 - not likely to work) to change your ceiling to whatever.  Save, reflash.

Next time you use aticonfig, check your ceiling through aticonfig --odgc

If it worked (seems to work on most of the 58xx cards I've used it on....) you'll see a higher ceiling.

I'm getting 380 MHs on my DIamond 5850s.  Default voltage. 
There's nothing you can do about voltage on a Diamond, right?

1000/300 memory/clock.

1025/250 does near 395, but asplodes a lot...

Never goes over 75C.
