Thanks mate, will do.

I'm also downloading Xubuntu 12.04 at the moment, so I'm going to roll back to that, then use Catalyst 12.8 and AMD APP SDK 2.7 to rule out any potential issues.

Cheers will report back

I am having a problem right now.

My Litecoin pool went down so I decided to reconfigure for another pool. I re-wrote the config batch file to point to the new URL but the card would not work, a 5830.

If I tried the original I=20 intensity the screen would momentarily blackout and the driver would fail then recover. Cgminer would then report the GPU as sick and shutdown.

Since then the old pool has come back online and, using the original config batch file, I can still no longer get any meaningful hashes at I=16, about 7kH/s. Any attempt at I=20 results in the same driver failure.

I have used 12.8 and 13.1 AMD drivers. Cleaned out all and restarted. Using the latest cgminer.

Has anyone had this problem too or might know what the problem is?

Thanks!

No idea. You're treading into unknown territory.

any way we could help debugging the dynamic intensity on windows?

currently on windows 8 64bit with just an hd 5850 it basically stick to I = 7 all the time, is that expected?

I see,

i'll be getting a few 7950 shortly and will see how does that will work.

I was used to bitcoin mining with pocblm and that with -f 60 was giving perfect desktop interaction and as soon as there was no desktop acceleration it was taking full gpu power :/

maybe it's just scrypt that can't be tuned differently

I got that error in bfgminer when i sat the intensity or the threads too high. One of it was it. The readme.scrypt has a good explaination how to setup the intensity max. I havent checked if the same max value applies for bitcoin mining.

Don't switch users.  Or if you do stop CGMiner and then reopen it in the other user account.

Just want to say I ended up rolling back to Xubuntu 12.04, using Catalyst 12.8, ADL SDK 5.0, CGMiner 2.11.4 (? Latest anyway), and APP SDK 2.7. Works perfect* and solved all the previous problems I was having. I recommend this combination to anyone who is struggling to get it working or looking for a linux miner.

Thanks for your help ckolivas.



* Ok one small thing, I'm using VNC now as a way to solve it, so it's not that big of a deal, but when I try and run headless and only ssh in it seems to disable all my GPU's. It doesn't seem like I can say Display=:0 as I don't have any displays in there.

Like I said, using VNC seems to fix it though.

I'd just rollback your drivers.  Shouldn't need to user a newer one for Bioshock, regardless of what it says.

I'm having problems with cgminer and AVG antivirus free 2013.  Note that AVG antivirus free does not have a firewall.
The most annoying thing is it was working fine Thursday and suddenly stopped working.  I can't think of anything I changed on that day, or before the last reboot.

I'm using the command:
1. If I start cgminer with AVG activated, most of the time cgminer will just display a blank screen (sometimes it runs for a bit and stops).  If I then disable AVG, cgminer will start and run normally.

2. Different scenario.  AVG is disabled, I start cgminer, it runs normally.  If I enable AVG, cgminer runs for a bit and then freezes.  Again, if I disable AVG, it continues.

Just for kicks I've disabled Windows firewall but it didn't do anything.  I've tried disabling individual parts of AVG but nothing happens, I have to disable the whole thing.

The debug text before the freeze isn't particularly interesting, just something like


Any ideas what to try or am I doomed to switch antivirus?
