just a few ideas:
- are your cards overheating?
- have you tried changing pool?
- have you tried changing mining software?
my guess that the problem is one out of these 3...
In my first post I explain that I have it watercooled and I have been monitoring temperatures, as that was a point made in another thread I found using google.
I have not tried changing pool. As I wrote in my first post I have another computer, using the same graphics driver, same GUI miner and same CGMiner. It is mining to the same pool and never stops like my big gaming computer does. I will try changing pool and miner whenever I get the chance, I just don't think that's the problem
I've had the same problem and the only thing that worked to stabilize was to reduce intensity.
Running 2x5770's I use "-I 16,17" with cgminer. The card handling the gui can't go above 16 and the second card can't go above 17 without instability. Since you have different GPU's your intensity numbers will vary. Check your System log in the Windows Event Viewer and you'll probably notice the driver stopped responding right before cgminer stopped hashing.
You might also want to try different Driver and Stream SDK combinations as that does matter. It's a pain in the ass to find the right combination, but might be worth it. Check other threads as this is discussed at length.
Even though I should probably be getting more like 390-400KH/s (Litecoin/scrypt), I'm comfortable with my 380KH/s right now as it runs stable for days without interaction and without heat issues.
Good luck!
Sounds possible that it could be because I am running 100% 100% of the time, but as written I have done that for about a month now. It only started doing this a few days ago, I have not changed anything prior to the issue.
This makes me not believe it is a driver problem, it also never seems unstable when I am gaming, and when mining I do not see any spikes in performance, it is rock solid.
I will however look into it, maybe it can stop the crashing if I lower the intensity a bit, thanks!
Dig in and get your hands dirty.....this IS mining we are doing....
CGminer does not need a front end.....drop GUIminer, and just use CGminer all by itself...
Lower your Intensitys for Starters....Their is a great readme in the folder for CGminer.
Don't be intimated by the Command line, it is all spelled out in the Readme. you should see anything from 680-700 for a 7970 (is what i get)...but hell your Watercooled..i want a report from you that you got 800++
Lower the Mem Clocks...not needed for Mining...I run, in one rig...
6870= E 900 M 525 I 9 Mhash = 266
7970= E 1110 M 485 I 14 Mhash = 675
7970= E 1110 M 685 I 14 Mhash = 666...<this is an MSI card and is being a bitch
Win7 X64, MSI afterburner to monitor temps. I can run these at 700 Mhash but is getting Warmer so downclocked the [E] engine clocks a bit.. By the Way Nice ass Motherboard i have that in my Gaming Rig, Sadly it has Nvidia for cards....lol
The Rig above runs weeks at a time, but i like to tinker so i shutdown now and again...last weekend to try again to Get it up and running with Linuix......sadly a fail...
But way Closer this time around.
Ohh I have gotten my hands dirty building this one from scratch
I will try not to use GUI miner and lower the intensity a tiny bit to see if that does the trick, thanks!
I have the high memory clocks for benchmarking/gaming, not for mining. I am using this system as my primary gaming computer.
http://hwt.dk/images/users/64693/afterburner.jpgThis is a stress test during lower clock speeds, even with high voltages I get pretty decent temperature readings, where 57C was the highest. I used furmark for this one. Mining might stress the cards in other ways that furmark does, but the temperature should not wary that much.
I also got a picture of the water cooling when I was just cooling CPU and both GPU:

Also, lowering the clock speeds to stock, as written in my first post did not help. I am still running stock clocks on both cards.
I actually get 600 on stock speed with the HIS 3GB but the powercolor only gives med 550. Pretty weird since they are both referance design from AMD, and the clocks are identical on both cards.
The other computer I have mining with 2x HD 7790 has an MSI HD 7790 which is definitely not as good to mine as Asus HD 7790 DCII is, maybe MSI's PCB's just aren't good at this stuff.
Anyway, thanks for the answers, I have a few things to try now but other ideas are always welcome!
