Wishful thinking - Macromedia Flash/Shockwave were much better products.


I was under the impression that GLSL was garbage (even worse than javascript) at mining...?

Good job!

You can step up in increments of 5, too.  For miners, there's  no real application for having proportional clocks.

Also.... who cares if the screen freezes?

On the rig I keep at home, my X session is completely unresponsive.  I manage everything through ssh with the monitor turned off and the screen set to blank after 5 minutes.

I'm not sure what you mean...?  AMDOverDriveCtrl will show you the current voltage, but it won't show you any sort of power consumption or separate voltages for GPU and Memory.


Whatever is reported back from the card as the ceiling is what AMDOverDriveCtrl uses, I think.  You'll need to flash to go higher.

What's up with every new pool requiring some ridiculous registration process?

Here's what happens for me -

From ssh, without AMDOverDriveCtrl running, my memory clock floor is 1175 (or something like that).

Trying to use aticonfig --odsc 1005,225 will not work (it says make sure values are valid).

After running AMDOverDriveCtrl (you can do this from ssh - export DISPLAY=0:0 ; AMDOverDriveCtrl &) and not touching it in the GUI, my memory floor becomes 150.

Trying to use aticonfig --odsc 1005,225 works.

It can be significantly more than 10%....

Stock I was at 292 MHs with poclbm.  OC'd I'm at 392 MHs with phoenix.

That's some 30%!

Over-time-damage can be a gamble and often you can damage more than just your videocard.  Cheap components on motherboards and PSUs will go up in smoke sometimes as well as getting a general life reduction.

Thanks, Artefact.  That sounds great!

The new graphs look good and are a lot easier to read, I think.  Thanks for spiffing the up, too.

Get AMDOverDriveCtrl and see if it will let you go below the floor set by default.

In my experience, on 5830s and 5870s, it will allow you to set a memory clock as low as 150.  No flashing, etc, required.

No worries about offense, but if you meant that in a passive aggressive way.... I'm trying to help you, bro.

I'm trying to tell you there is a relationship to overclocking the GPU and the memory clock.  There is a correlation between the two.  You can't just try one single value and give up the goose.

So again.... have you tried fiddling around a bit?  The last aticonfig dump I saw had a single value for memory that wasn't adjustable.....    It took me a whole day to find the happy-spot on my 5850s - and one stupid one hates running at 1005 and only seems to work at 995.  The final outcome was 1005,225 for 395MHs with phoenix - something I could never get in Windows (I did try, though, quite a bit....).  The weird card only runs at 995, 300 for 360MHs - still 70MHs more than I got in Windows.

I'm in no way promising you'll win the game with Linux.... I'm just trying to help you out.  Linux is a bit like a paintbrush that requires a bit of finesse, patience and pre-built skillsets to produce something beautiful.... Windows is a bit like a steam roller covered in paint - guaranteed to paint "something" pretty broadly.

ssh does beat the pants of managing stuff through a GUI - but did you know you can get tools like Cygwin and sshd for Windows?  You can even get screen - then you can detach the session from the Windows console and recover it from an ssh session.

If it's such a big deal - go back to Windows.  No hard feelings here.

#1 Stop wasting your time reinstalling.  The GPU operations are independent of the OS.

I'm using Fedora 32, but that shouldn't really matter.  The only difference is the driver software from AMD.

I'm using Catalyst 11.5 with SDK 2.4, but others suggest 2.1.  I think the phoenix creator suggests 2.4.  Either way, I'm not sure you even need this....

I would send you my HD5850 BIOS, but it's probably no different than what you have with the exception of a few numbers changed that you can change yourself in RBE.

My changes -
"Additional Changes" tab, method 2, CPU to 1200
CPU 0 through CPU 3 in the profiles thing with Memory clocks to 125 (I think you can skip this step if you're using AMDOverDriveCtrl).

Use aticonfig to set my clocks on the cards.

Run phoenix.  I just recently switched to phoenix+phatk from poclbm, but either will work.

A few other mentionable changes -
I boot into run level 3 (no GUI) and manually start X with "xinit -e metacity" (not sure how much/if this actually helps, but it's more stable than booting say..... Gnome3).
You can use twm or any other default if you want, I just happen to like metacity and it's on my machines, anyway.

@dudel42 - Once AMDOverDriveCtrl is running, you're free to use aticonfig to adjust clocks.  If you decide to use AMDOverDriveCtrl, make sure you hit the "set" button.  When the miner starts cranking away, it should automatically switch to whatever you've set the "High" profile to.

Douche move, guy.  Douche move.

You sound whiney, presumptuous and in contempt for everything you don't have.

Way to go.

Implying the "idiots" with access to these machines couldn't possibly be as clever as you?... "climbing a corporate ladder" to get access to a PC lab, leased servers or a school network?  How stupid can you be to make that claim?

Better yet - how stupid can you be to think that a lot of us don't have pre-existing infrastructure?

... I can see why you're not on the same corporate ladder rung as the rest of us idiots.

I'm sure you can get a bit more oomph.

Fiddle with the clock settings with aticonfig until you find a sweet spot.  It's a bit of a fiddle game (unless you know someone with an identical card...) and sometimes it doesn't always make sense....

I get *less* MHs at 900,400 than I do at 875,1125

Current settings are 1005,225 and it took me a while to figure that out - I was getting less at 1005,325 than 775,1125!

For the people asking for an AMDOverDriveCtrl howto - if you look at the sourceforge project, I believe they have prebuilt .deb packages.  No reason to rebuild it unless you're trying to set it up on Fedora or some other distro.

Someone's changing my graphs!

Artefact - I dunno if this is technically possible, but is there any way to have a payout counter?  At minimum, something like "6 payouts today" or ideally one that listed out the payout and the amount?

And by payout I mean block generation, not > 1.0BTC payout.

Alright, minerX!

What parameters are you using for poclbm?

I think -i X let's you choose adapter X.

<?php
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://blockexplorer.com/q/getdifficulty");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch);

echo $result;
?>

Oh, cute proxy...

I thought about using PHP but went with C++ instead.  And C++ let's me do more evil(tm) with less effort.

I say..... Go get AMDOverDriveCtrl and see if you can back off your memory clocks.  It will make a definite difference if it doesn't clear up your problem.
