Title: cgminer hw errors Post by: silverjim on April 09, 2013, 08:50:53 PM Hi. Since I'm posting in the newbie forum, it can be accurately surmised that I am a newbie. I'm running cgminer 2.11.4 and using an Nvidia card GTX660TI. My system is Win7 64-bit, 16gb memory, and a OCed 2500K Intel CPU. My kh/s in cgminer is around 62, while coinotron scores it anywhere from 14kh/s to 55kh/s (depending, I guess, on the phases of the moon).
The top HW number is always 0. The bottom one is slowly climbing, and reads 200 right now after 20 hours of running. I've seen where the HW number should always be zero, but I've not seen which one it refers to. Here's my .bat file cgminer --scrypt -o stratum+tcp//coinotron.com:3334 -u xxx -p xxx --shaders 1344 --intensity 12 --worksize 64 -g 1 My question is two-fold. First, should I be concerned about the HW number? What is the difference between the top and the bottom HW numbers? Second, is it normal for the coinotron numbers to vary so widely. Thanks for any and all help. If there's any more information that you need before you answer, I'll furnish it if possible. -silverjim- EDIT: I'm using litecoin.

I have similar problem with my ATI gpu and I cant get more than 50% hashrate these cards can get. I start getting HW errors around intensity 12 and 13, intensity 14 has about 90% HW errors. Sad is some have intensity set to 19... I guess it is because my RAM is old - DDR2 at 533MHz
good luck |
