Title: Help with high HW errors and r9-270x? Post by: terrapinflyer on February 14, 2014, 08:31:47 AM Im hoping someone can help with this problem, I cant seem to get my r9-270x-CDFR's to run stable in cgminer 3.7.2 my conf file looks like this:
Code: "intensity" : "17", The cards are showing ~450kh/s but are throwing crazy HW errors and eventually cgminer and or windows 7 crash. When I try to set my thread-concurrency to 12000 cgminer will not start. Any help would be greatly appreciated and I would be happy to tip anyone who can get me up and running.

You don't need to specify shades when you specify TC, but anyway, you need to increase your TC, try something like 15232, 16384, 16640 or 15361 (shaders*n + 1 usually works best). If that doesn't help, than reduce your clocks speed back to stock and try again. Also, try and leave lookup-gap at its default value of 2. Title: Re: Help with high HW errors and r9-270x?

That TC 15232 will only work if I make the lookup-gap set to 4. That drops my hash rate to 300kh/s but no more HW. Im going to try increasing the TC like you suggested.

Title: Re: Help with high HW errors and r9-270x? Post by: atp1916 on February 14, 2014, 11:20:54 AM I've found TC 10240 up through 24000 to work well on my 270s. Anything less and it was HW city.
