Title: getting avg of 540khash w/ gigabyte 7970 using cgminer..any help? Post by: iruleeveryone28 on April 09, 2013, 06:59:45 PM cgminer --scrypt -o http://xxxxxx -u xxxxxxx -p xxxxxx --intensity 13 --worksize 256 --thread-concurrency 8192 -g 2
any ideas? should i be using a conf file instead? Title: Re: getting avg of 540khash w/ gigabyte 7970 using cgminer..any help? Post by: iamrickrock on April 09, 2013, 07:09:12 PM That's about the same as I get on my 7970

and your motherboard/cpu? Title: Re: getting avg of 540khash w/ gigabyte 7970 using cgminer..any help? Post by: roy7 on April 09, 2013, 10:13:19 PM Overclocking memory speed helps a large amount with scrypt. Also set powertuner to +20.

Post by: iruleeveryone28 on April 09, 2013, 10:22:28 PM what's your GPU clocks? and your motherboard/cpu? well, i added --shaders 2048 (not sure what this is but it seemed to make a difference) and pumped the mem up to 1600. got ~600 but the computer konked out after about 5 minutes. will try 1550 see if its more stable Title: Re: getting avg of 540khash w/ gigabyte 7970 using cgminer..any help?

Post by: iruleeveryone28 on April 09, 2013, 10:33:06 PM with mem @ 1600 and GPU @ 1000 and no power control im getting over 600, but its unstable and crashes.
with mem at 1600 gpu at 1000, 20 power control im averaging 520 :( Title: Re: getting avg of 540khash w/ gigabyte 7970 using cgminer..any help? Post by: meebs on April 09, 2013, 10:44:56 PM try this...
--scrypt --thread-concurrency 21712 --intensity 20 -g 1 -w 256 at 1000/1500 on my sapphire 7970 I get about 680khash. If i go up to 1050/1600 i'll get 710khash.

If i go up to 1050/1600 i'll get 710khash. the card really doesnt like intensity above ~16 it tends to crash, would you still recommend trying it?

Thread - being disabled you didnt mean 21760 by any chance? Title: Re: getting avg of 540khash w/ gigabyte 7970 using cgminer..any help? Post by: peacefulmind on April 09, 2013, 11:19:48 PM I have posted the same thing.
I have 2 sapphire 7970s that get 700kH/s. (these are vanilla 7970s) I have 2 other sapphire 7970s that won't go over 550kH/s. (these are "GHZ" editions - but actually are much worse for hashing - so far). I have tried everything under the sun. The difference I am starting to think has to do with the BIOS version that is on the card itself. Any thoughts on flashing the GHZ editions to a plain old 7970 BIOS? |
