1  Bitcoin / Mining software (miners) / Fighting heat; tricking the ati driver to continue mining on crash? on: July 12, 2011, 12:15:23 PM
OK so with 3 cards it gets pretty hot. Sometimes the card in the middle will throttle/lock/reset or whatever the driver does. On Windows you get "Ati driver has recovered", on Linux you just get a card that sits at low utilisation or Xorg locked.

What i've noticed is that it falls back to the "Level 0" profile clocks.

Quote
<PERFORMANCE_LEVEL level="2" gpu="72500" mem="100000" voltage="1088"/>
  <PERFORMANCE_LEVEL level="1" gpu="55000" mem="90000" voltage="1038"/>
  <PERFORMANCE_LEVEL level="0" gpu="15700" mem="30000" voltage="950"/>

Sometimes it mines, sometimes it doesnt, i havent really looked into it that much (need confirmation on what happens when it crashes/locks etc). Sometimes i get home from work and the card in the middle has been near idle for nearly all day. Obviously this is not ideal.

Instead of writing scripts to detect GPU load, heat etc and to restart your mining program/machine, has anyone raised the "Level 0" clocks to the card's default speeds? If the card dies for whatever reason, it should fallback to the set clocks which it can continue mining.
2  Other / CPU/GPU Bitcoin mining hardware / Why does everyone use AMD when using 2+ cards? on: July 03, 2011, 02:00:38 PM

Not bashing AMD. Purely discussing cost effective parts. CPU (Intel G620) is the same price as a cheap AMD (X2 260). Mobo can fit 4 cards for 2-3x less than a high end AMD board.
Everything else is the same (DDR3, Sata HDD or USB Flash etc).

1x slot has no effect on the cards performance.
3  Other / CPU/GPU Bitcoin mining hardware / My cards seem to throttle when heat rises? on: June 28, 2011, 02:10:11 PM
After 70-80 degrees my cards slow down. This is at 300 mem and default core clocks.

5850 and 6970 both do it (on different machines, linux and windows)? Is it me or am i paranoid or something?
4  Bitcoin / Mining / My generated results per hour = megahash per second - 50 on: June 26, 2011, 02:00:31 PM
On 3 different cards on 3 different machines. % rejected/stale differs on the cards.

Shouldnt this be random?
5  Bitcoin / Mining support / aticonfig "ERROR - Get clocks failed for Adapter 0" on: June 23, 2011, 01:07:55 PM
What to do? The other 2 cards function normally, i cannot mine using adaptor 0.
