Use them to mine Zcash, much more profitable !

Sorry for this.
I just find out that one of the card is actually almost fried, that's probably the issue.

Hello miners !

2 years ago, I was mining with 5 R9 280x using a H81 Pro BTC, windows 8.1 and some mod drivers.
As it's sooo profitable, still with these gpu, I decided to power everything on again.
I updated my rig to Windows 10 and installed Crimson 15.12. I read some topic saying that windows 10 can handle 6 gpu easily.

But I can't get my 5th GPU working, it's detected by windows, but still showing error 43.
This GPU is working fine when only 4 GPU are plugged, but since I connect a 5th one, the error is back.

I'm guessing maybe this driver is too old and I should install a new one? But I'm scared to mess everything up and I prefer to get your advice

Hey Dargo,

I'm using Kraken since a long time, but made my first big SEPA EUR withdraw about 20 days ago, and it's still stuck on "On Hold" since.
I wrote a message to the support last week, but still didn't get any answer from them. My ticket number is the following : 351580
For information, I'm verified until Tier 2.
Can you help me with that ?
Thanks in advance
