Running 2 instances of CGMiner

[Trustor]

Hi

I have 2 graphics card. 1x 5870 and 1x R9 280x.. I have 2 batch files that I configured on the desktop. The R9 280X is as follows:
C:\Users\RIG1\Desktop\GPU0\cgminer-3.7.2-windows\cgminer.exe --scrypt -d 0 --remove-disabled -o XXX -u XXX -p XXX -g 2 -w 256 --thread-concurrency 8192 --lookup-gap 2 -v 1 -I 13  --gpu-powertune 20 --auto-fan --temp-target 70  --gpu-engine 1000 --gpu-memclock 1500


The 5870 is as follows:
C:\Users\RIG1\Desktop\GPU1\cgminer-3.7.2-windows\cgminer.exe --scrypt -d 1 --remove-disabled -o XXX -u XXX -p XXX -g 1 -w 256 --thread-concurrency 8192 --lookup-gap 2 -v 1 -I 18 --auto-fan --temp-target 72
When I run the R9 280X batch, the card starts running, when I run the 5870 batch, the pc freezes and I have to restart.
Am i missing something that I need to do? I created 2 different batches because R9 280X likes the -g 2 while the 5870 likes the -g 1.
I have the latest amd catalyst driver.

Best Regards,
Trustor

I do that all the time. Tho the 5870 will probably like an older version of cgminer. Try nothing newer than 3.1.1 for the 5870.

[Trustor]

I use 3.1.1 only for the 5870 and I keep the 3.7.2 for the R9 that will work ? :O

EDIT : It didnt work 

[darksoft]

The only other thing I could think of is the version of the driver for the cards. Have you tried running the 5870 first and only the 5870?

[darksoft]

And how big is your power supply?

[xocel]

Make both configs configure both cards but only enable 1 each. e.g

Code:

 -d 0 -I 13,18  --gpu-powertune 20 --auto-fan --temp-target 70  --gpu-engine 1000,[5870s core] --gpu-memclock 1500,[5870s mem]

and

Code:

 -d 1 -I 13,18  --gpu-powertune 20 --auto-fan --temp-target 70  --gpu-engine 1000,[5870s core] --gpu-memclock 1500,[5870s mem]

having the single settings tells cgminer to set all cards to those settings. If you start the first script its fine, when you start the second it tries to reconfigure gpu 0 to the second scripts settings. Even with the -d, cgminer starts and applies settings before disabling the threads on the disabled gpu's.

Hey guys thanks for your reply !  Merry Christmas  
darksoft --> I got a 850W 80+ bronze PSU
Actually I got them both running with -g 1 and it work... But I loose 200 kh/s on the R9 280X because this little baby like more the -g 2 settings ^^

Yes I have tried to run first the 5870. It work fine but when I launch the R9 I got a message from windows : the amd catalyst driver crashed and the kh/s from the 5870 decrease until the pc freeze / crash.

xocel --> I will try

Hey guys !
I have been away this fews days. I was finally able to try different setting on my config today. The config from xocel work for my two cards there is no more crash or freeze, that's great ! Thx  
But I got one more problem... My R9 280X dont want to break the 700 Kh/s wall
I was able to reach 610 kh/s with these settings :

Code:

 --scrypt -d 0 --remove-disabled -o xxx -u xxx -p xxx -g 2 -I 13,18  --gpu-powertune 20 --auto-fan --temp-target 70 -w 256,256 --thread-concurrency 11200,8192 --lookup-gap 2 -v 1 --gpu-engine 1000,900 --gpu-memclock 1500,1250

If I set gpu-engine to 1050 or 1080 its worse for my hash
Do you have any idea how to break the 700 kh/s ?
Im running a HIS R9 280X

[Trustor]

Can someone help me please? I have try to reinstall latest amd catalyst driver and amd sdk... Im trying different config but its getting worse...

The 280x doesn't like the core higher than 1030. Remove any gpu-engine and thread concurrency command and just put in --shaders 2048
