OS: Win 7 64 bit, phoenix 1.4, SDK 2.4
I have some issues getting all the gpu's to work properly. And thus I have some questions:
I read in this thread: http://hashcat.net/forum/archive/index.php/thread-421.html
It says there that you need 4 monitors connected if you want to use all cores (4 in total) on 2x5970. Can anyone confirm this?
Also a possible solution was stated in that thread to have the cards connected with crossfire, and then just have one monitor
connected to one of the cards.
I wold think it was logical to have only one monitor connected to each card to make the mining work on all cores, do I really need to get
dummy connectors for all DVI-outputs?
I have two cards, both 5970, let us call them A (d0,d1) and B(d2,d3).
d3 never semmed to work properly with any miner that I tried. It worked for a short while then froze.
Please see this picture for the behaviour:http://imageshack.us/photo/my-images/859/gpuactivity.png/
I tried to remove A and insert B only. then d2 and d3 both performed well with phoenix. Once I insert A, I have issues with d3 again. It just starts, runs for a few seconds, then freeze. There is one monitor attached to a cable from each card (I tought this was sufficient).
I'm stuped as to how this problem occurs, and I'd like to set up the source for phoenix to run some debugging with it to see what really happens here, but not sure which environment to use, and how exactly to do that, but if anyone gives me any pointers. I'd figure it out.
I am tempted to write off d3 as an hw issue, but won't give up just yet.
I'm interested in knowing which software versions and how cables and/or dummy plugs are connected to your cards if you run a dual 5970 setup under windows.
Also would I possibly have more success if I used Ubuntu? My next move will be to install Ubuntu to see if I can get all cores working under Ubuntu. I really don't care if I use windows or Ubuntu, all I want is to get this damn thing to work. Again, if anyone helps me to solve this issue, I'd gladly donate a sum that will make you feel it was worthwhile helping me. I've been looking into this on and off for weeks, but intensified the efforts the lasts days, so far with limited luck.
I was thinking of alternative solutions like restarting d3 mining every time it locked up (would not be optimal, but better than nothing), but when I restart the miner, nothing happens, a reboot is actually required.
I run one bat-file for each worker, the content of each file is as follows, with device ranging from 0 to 3.
phoenix -u http://firstname.lastname@example.org_1:email@example.com:8332 -k poclbm DEVICE=n -v VECTORS BFI_INT AGGRESSION=11
I I run poclbm from the command line with no parameteres, it too will freeze. Gpu-Z or GpuCaps will not run either. So I suspect there might be something wrong, and I am not sure if the hw or the sw is to blame. But for the record, d0,d1 and d2 runs just like a charm, it's only the 4th gpu, device 3 that's not working. That'll be the slave gpu on my 2nd 5970.
Thanks in advance for all the help you can provide.
