The strange thing is that 13.1 was working before, although I was getting some strange artifacts (which is why I upgraded to 13.2 in the first place). Here is the hs_err_pid file: http://pastebin.com/tyrmpren
I would honestly be OK with simply downgrading to an older version of Catalyst. The only reason I upgraded to 13.1 in the first place was to see if that made a difference to the stability of my PC (it didn't). I think those stability issues were caused by some problem with my windows installation because if I boot from my secondary HDD, that issue seems to go away (although I have not tested it enough to be 100% certain). Unfortunately, though, AMD will not let you download older drivers from their site. If anyone knows of somewhere that I can get a nice, clean virus-free copy of 12.x, that would be awesome. Thanks!

So I tried uninstalling the 13.2 drivers, running driver sweeper, then installing the 13.1 drivers. Unfortunately, now the bitminter client will not open at all. I saw that you said this was caused by the virtual machine crashing and could be solved by uninstalling drivers, running driver sweeper, and reinstalling, so I tried that again, but I am still having the same problem. any ideas? I can post the hs_err_pid log file if you like. thanks again for the help.

Thanks for the info!


thanks for the help, I will look into this.


hmm I don't really think it is a problem with the gpu, as I am currently running both GPUs at stock speed (I wanted to get the stability worked out on stock speeds before overclocking) and neither of them get over 80ish degrees (my main card stays under 70 the majority of the time, depending on ambient temps). And I am not getting any miscalculations in bitminter or artifacts visually, so I am thinking the GPU is solid. Thanks for the help though! Any other ideas?

also, is there an easier way to quote specific parts of a post than doing it by hand in the post?

Hey guys, new to the forum, so please let me know if I am doing anything stupid.

I had a question about the bitminter client: I am currently running the standard bitminter mining client (the latest version, but not the beta version) with 2 different GPUs. One (the main one, which I use for my display) is a Sapphire Radeon HD 7870, and the other is a ATI Radeon HD 5850. Previously, these two cards would run together perfectly fine, and i would get exactly 666.6 Mhps.

I was, however, having some system instability, so last night I updated my GPU drivers (for both cards). (It didn't help, but it was a bit of a long-shot anyways). Now every time I start bitminter, i get a bfi update failed error for the 5850 and that card gets nothing but miscalculations. Of course, I can get around this by simply unchecking "use BFI_INT if available" for that card, but that reduces my hashrate by about 30 Mhps. Naturally, this does not seem idea.

Searching around, I saw that this seems to be a common problem using more than GPU, but according to what I've seen, plugging a monitor into the second GPU should solve it. In my case, this did not work. Even with my monitor plugged into that card, I still get the BFI update problem.

So my questions are 1: what exactly does this BFI_INT do? and
2: Does anyone have any ideas for what to do to solve it?
and I guess while I'm writing all this out, I may as well ask if anyone has any ideas what would cause a computer to just completely freeze up with no warning, no changes in fan speed, etc. The only things that I can tell for sure are happening are that the screen completely freezes and any sound or music playing will also stop (just stop, no catastrophic failure like you would normally get on a bluescreen or something).

Thanks in advance for any help!
