Mining new user and graphic card problem
-
You’re welcome =)
Yes, I have 3x PowerColor 7950 PCS+ running stable for 20+ days with these settings. Especially --thread-concurrency can produce errors. 8192 or 16384 seem to be good settings for decent performance and 0 HW errors for 7950 cards.btw I had a typo in my reply before the edit. 16384 is the proper setting I wrote 16834 or so at first. please double check you have the correct value of 16384 =)
I’m using this driver version [url=http://www2.ati.com/drivers/beta/amd_catalyst_13.11_betav9.4.exe]http://www2.ati.com/drivers/beta/amd_catalyst_13.11_betav9.4.exe[/url]

yeah the value is correct: 16384. Okay, with your bat and the 3.7.2 I gained a bit of speed, now I run at around 260hs/s, but if I had to set the Intensity at 12, beacuse if I go one click up I get a crash :(.
I dunno, even not being an expert miner, I smeel failed hardware. Last thing I have to try is to mount it on my other computer (i7 4770k, 16gb ram and asus z87 deluxe) and see what happens). If I get the same things, tomorrow morning I will go back to the shop.
What do you think?
-
Did you try the BETA driver? If the Beta driver does not fix it, it’s probably a faulty card :(
If even 3dm crashes the card, something’s fishy. -
downloading them… should I unistall the previous drivers or I can install over them?
-
with ati I’ve read it’s better to uninstall old drivers first. worked for me.
-
still crashing… :( running out of options…
-
=( ok, i think the last option before returning card is testing it in the 4770k box.

looks like we were wrong. On the i7 4770k works fine. I can go all the way up to intensity 20 and I run at around 520kh/s. Do not know if it is still a bit low, but still, looks like now is working. I don’t know if to be happy or not, since I do not want to mine on this computer, as I use for work :D
I guess I will try to install linux on the i5… do you think this could help? Is it hard to set up cgminer on linux?
btw, thanks a lot for all the help so far, you have been really really kind! :)
-
also 3dmark did fine, with a score of 6376, which looks fine. I really cannot understand what could be the reason of such problems on the i5 machine. I was ready to say the graphic card was faulty… maybe the PSU is not so in shape anymore? Is 4 years old and is kraun, so not the best brand I guess. I am thinking that the psu could be one of the possible reason, the first that come to my mind for such a behaviour.
Do you have any ideas?
-
yeah, replacing the gfx card eventually would have been less of a hassle :p you could try switching the PSU, if you’re not too lazy =)
I also had my first 2 cards running with an i5-760 + asus p7p55d-e, but replaced it with an asrock am3+ mobo with athlon x2 cpu which I got off of ebay for like 60EUR b/c I wanted to add a 3rd card. The system is also using ~40watts less power now compared to the i5+asus. Could be an option for you, if the PSU is not the issue =)
-
I will try to switch the psu and see what happens… In the mean time the card worked at 620 kh/s at intensity 18, so I guess the speed is good. There was another problem though. I left the i74770k mining all the night to see what happens. temp and all was fine, but when I came back this morning it was not mining and cgminer said failed something and instead of the hs/s there was written DEAD… not nice a all! :-\ I tried to restart cgminer and it was working but at a much lower speed (around 300 kh/s). I tried a 3dmark and it was finished but the score was almost half of the yesterday’s score. I restarted the computer and everything went back to normal. However I did not like this thing at all…
I just woke up when I saw the problem, so I did not think about taking a screen of cgminer, I was still sleepy…
I am going to switch the PSU and see what happens.
PS: the radeon makes a hell of a noise! my 570 in comparison is like total silence…
-
it was the psu! 700watt, but not good anymore I guess. Already bought a new one, working good now!
Thanks a lot to anyone who helped me, is nice to see such an open and supportive community here! I have more questions about feather coins, but I guess is better to open a thread in the proper section now!
Good mining to everyone!

awesome! glad you finally got it to work!
happy mining ;)
