So, I've been mining scrypt steadily @ 140 kh/s on my 1Gb Asus 5770. This has been going great for many months, with no HWs. I have the Catalyst 13.1 display-driver and SDK. Doing the switch to x11 have proven tricky. I've tried seven different versions of sgminer, based on 4.1, 4.2 and 5, and they all give me HWs and no accepts; some more HWs, some less. The high-speed version from Lasybear seems to work the best, with the first HW coming after apprx 5 min on I 15 and 900 kh/s.
I clocked the card incrementally down to 150/225, to no avail. As in scrypt, the thread concurrency offers the most at exactly 7860, and in- and decreasing it by six orders of 64 made it go slower and did not help with the HWs. Regulating intensity does not affect the HWs.
I've tried with different kernels, including darkcoinmod and x11mod, but to no avail. I tried x13 as well, but the HW-problem persists.

Edit: So, I finally did some reverse cogitation and installed the 14.4 drivers on top of the 13.1s. Getting 750 kh/s with Laybear's x11mod. The Sph-b2 is slow, around 250 kh/s, but HW-free as well. The heat still keeps my small flat nice and warm, but less so than before. The original 14.1-release BSODs, and the four others give HWs.

i have a very simple fix for your problem, move to a whole different algo, X11 and "possibly" other X algos have been compromised by FPGA so gpu's have poor chances there to. your better off looking into fresh, cryptonote, JPC or some other algo that isnt controlled by the few. |

You should be fine with Catalyst 14.6 Beta and SGMiner5. You could probably bump up the intensity a little once you upgrade. Any issues just send me a PM. |
The new generation have arrived and they brought their own currency...

Thanks for the help, guys. I see I have a typo in the EDIT I did in the first post. It's supposed to be 4.1, not 14.1.

Show me evidence of fpgas. Your subtle plug for cryptonote is not so subtle. fpga has shown to be not cost effective, with the exception of top of the line hardware costing thousands each. https://darkcointalk.org/threads/darkcoin-fpga-mining-co-op.836/ |
