CGminer HW: Error.

XHD600X · June 4, 2014

Hi guys,

Me again, I was mining when i saw the number of HW errors rising, it stopped at the amount of 20 but only on my second GPU (HD7770) Whilst my main GPU (HD7850) is on a weirdly high Kh/s.

Picture:

My scrypt code:

cgminer --scrypt -o stratum+tcp://stratum.netcodepool.org:4093 -u ANUSZEEKAMEEL.HeadPC -p 12344321 -I 18,18 -g 1 -w 256,256 --thread-concurrency 16000,8000

Thanks in Advance!

Turn down your overclock

GPU 0 is not running weirdly high, it's absurdly low. that's 952 hashes. Not 952 K/hash. The average is showing it at 3 K/hash.

GPU 1 may have too high of an overclock, high thread concurrency, a combination of the two, or even an imbalance of overall settings.

The hardware errors result in lost work and wasted mining time, check your pool stats to get a rough estimate of how much you're being credited for.

Consider returning to stock settings and starting fresh with tuning the cards.

Have you taken the time to crunch some numbers? You may very well be able to purchase more coins for the same cost in electricity you would spend mining. Mining is more of a zero sum game, it's not something for pure profit. It's a way to acquire coins by paying for electricity and hardware over time instead of directly buying them. You're still paying for the coins when you mine them, and in some cases paying more when you mine them.

I copied the code from https://litecoin.info/Mining_hardware_comparison It's the exact same,. The GPU's aren't overclockd in any way. I will look at some other tunes though!

I like to mine for fun, My pc is running 24/7 and at night the electricity costs are lower than during the day. When i started i thought about it and i'm aware that i could lose money but so be it. It's fun for me to do and i learn stuff from it...
