I re-installed Win 8.1 from scratch and it works…very odd…

1 thing I learned from this:

after installing Win 8.1 and running all the updates apparently this is enough to have the appropriate drivers for the GPUs, no need to download and install AMD Catalyst.

so someone says in other forums and seems correct…maybe installing AMD Catalyst cons=fused things? …mmm…anyway thanks for hte help…

Love the hanging rig option, it’s kind of close to the breaker/fuse box, is there some free electricity going on there? ;) :D

I actually have one cgminer instance for every GPU, since if one instance crashes I only have downtime on that instance. Also, I use separate workers on all of them so I can pinpoint issues via pool statistics (ie which card is not working). You can’t have different pools/workers on one cgminer instance.

but even with that, you need to list all per-gpu settings separated by commas, or the next cgminer instance you are starting assumes that the settings from it’s cgminer.conf apply to all the GPUs.

Memlock is already 1500, glad that’s the best option.
I’ll try lowering down the powertune, if that keeps the temperature down then is great.
and will try tweaking the PGU.
thanks again

R9 270 and 280/280x cards work just fine, out of the box. There is no support for the 290 at the moment, though it may not be very far off. Next Mac Pro will have AMD FirePros, and Apple is still playing with AMD driver improvements.

Just to clarify, those cards will work on a Mac with Mavericks, but the drivers will still suck for mining. I custom built a hackintosh with 7970 in it, and it works great except for OpenCL/OpenGL functions. Apple’s drivers are not anywhere near using the card’s full strength, so I mainly have my hackintosh mining in linux on one SSD, while OSX is installed on another SSD.

The $/khash is too high for this, and resale value is very low once it’s outdated… its worth it only if you got expensive electricity. 2nd gen will probably be much better, if the algos might be changed to fight that…
