Title: Problem with Sgminer + xintensity? Can't set memory clocks. Post by: crazyates on February 04, 2014, 03:30:40 AM I'm using Xubuntu 13.10, AMD 13.11b9 drivers, APP SDK 2.9, and ADL SDK 6, SGMiner 4.0.0. For hardware, I'm using Gigabyte 280x and PowerColor 290 cards.
I was able to build sgminer just fine. Compared to sgminer 3.7.2, I can close it without crashing X, and I get about the same hashrate. I'm trying to use the xintensity option. Whenever I do, I get TERRIBLE hashrates. Like 10-15kh/s. SGMiner shows "I:8" on the side, which doesn't make any sense, and the mem clock is running at 150MHz. I can't manually change the mem clock; it's just stuck at 150MHz. I also can't change the I; it's just stuck at 8, which doesn't make any sense cuz I'm trying all sorts of values from 80 to 1100. When I go back to using normal intensity rather than xintensity, everything works. I: reads as whatever I set it to, and the mem clocks change just fine. Anyone know why this would be? Did it build wrong somehow? Thanks! Title: Re: Sgminer xintensity on 290? Post by: Treggar on February 04, 2014, 04:00:28 AM I use 410.

Post by: crazyates on February 04, 2014, 04:05:09 AM I use 410. "xintensity" : "410,410,410,410", The issue is not what xintensity to use. The issue is that when I try to use xintensity, sgminer won't change the GPU mem clocks. I'm stuck at 1050/150, and I'm getting 11kh/s. Title: Re: Problem with Sgminer + xintensity? Can't set memory clocks. Post by: Treggar on February 04, 2014, 05:01:16 AM Couldn't say then. I used exactly the same OS and package versions as you to build sgminer.
Title: Re: Problem with Sgminer + xintensity? Can't set memory clocks. Post by: crazyates on February 04, 2014, 03:21:22 PM Don't think it's a problem with building sgminer wrong. Tried Litecoin BAMT 1.3, and it does the same thing. Balls.

Title: Re: Problem with Sgminer + xintensity? Can't set memory clocks. Post by: crazyates on February 13, 2014, 04:24:44 AM I ended up switching to BAMT, and I had the same issue, which tells me I didn't build SGMiner wrong, nor was it a problem with my OS/drivers. I ended up upgrading to BAMT 1.5 (with the 14.1 drivers) and building a new version of SGMiner 4.1.0, and the issue went away. I can now use xIntensity just fine.

The issue is that when I try to use xintensity, sgminer won't change the GPU mem clocks. I'm stuck at 1050/150, and I'm getting 11kh/s. My cards go to 150 memory when I overstress them with wrong settings and then card's won't allow to change clocks until I reboot system. Try using different xintensity until u get one to work (try values between 1-10). Title: Re: Problem with Sgminer + xintensity? Can't set memory clocks.
