Tune, tune, and re-tune!!

Can you copy and paste your cgminer window? I have to see it to believe your are at -I 20 without any HW errors
-
I didn’t say no hardware errors, but then I don’t know how to check…
But heres a couple of screen grabs for you to take a look at, if you can let me know where I would see hardware errors that would be grand :)

Let it run for a while. you see the HW on those pictures you sent me? The HW: 0 part… if the 0 goes up thats a hardware error. Normally 7970s cannot go beyond -I 13 without getting tons of these.
-
OK, thanks for the explanation. do these numbers get reset every time I disconnect from the screen and then resume it?
-
no it shouldnt. Whats your hashrate reading on the pool’s website? is it relatively close to your actual hashrate? if its drastically lower thats also a sign.

“intensity” : “20”
[/quote]Weeeee! Good luck.

Hash rate on the pool is pretty close to the rate reported in cgminer 8hrs mining and no HW errors reported yet!

[/quote]Weeeee! Good luck.
[/quote]Is that a good luck as in I’ll be lucky to get away without HW errors for long or as in I’ll be lucky not to blow something up?

I have just put mine back to default settings on clock and men speed as last week a big spark flew out of one of the power connectors going to a card!
Left the card off for a day or 2 but then popped it back and been running a week with no problems. At standard settings i get 595 khash/s
I use GUi miner with GPU 7950 high settings but tone down the intensity to 19 on two cards and 18 on the other as this one gets extra hot for some reason.
Its stable so leave it there, never tried the other mining software as is command driven and not had chance to get head around it…?
7950’s 1.8 Mhash/s and stable so happy with that
-
i never run -I 20 but -I 19 is normal on many 7950s.

OK so a few more numbers from this morning to see how she’s holding up…
No hardware errors reported after running for 8Hrs
Load: 99%
Fan: 67% (2968)
Temp: 63.0 c
@ the wall: 430WBut I will admit, I have just had to do a bit of sorting out in the office as SWMBO is turning up later, and as part of this I have disabled everything not being used in the BIOS and removed the HDD that was connected as I’m running of a USB stick so that might be the 10W difference.

[/quote]I’m beginning to feel that you guys are trying to tell me something here and maybe I should drop down to I=19 and lose the extra 16Kh/s the I=20 is giving me to prolong the life of the setup.
