Title: amd radeon 7970m only getting 250khash/s Post by: El Dude on April 03, 2013, 08:26:36 AM have a 7970M using guiminer and only getting 250khash/s , What should I be getting?

forgot to mention that sorry , mining LTC , how come with I try to mine with the other gpu both hash rate drop to 50khash/s? Title: Re: amd radeon 7970m only getting 250khash/s Post by: seljo on April 24, 2013, 08:11:33 AM Anyone mined bitcoin on 7970m and what are the results?

Title: Re: amd radeon 7970m only getting 250khash/s Post by: wolf1 on April 24, 2013, 08:30:26 AM 7970m is basically under-clocked desktop 7870
desktop 7870 at 1000/1500 MHz gives about 400kH/s ... https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison so 250kH is maybe appropriate, probably not possible to go over 300 in guiminer try to use defaults for 7870 not for 7970 try thread-concurrency 15360 or 16384 maybe also try cgminer instead of reaper to see if there is difference BTW what is your GPU temperature during mining? Title: Re: amd radeon 7970m only getting 250khash/s Post by: btbrae on April 24, 2013, 10:42:39 AM With cgminer i use -g 2 which is gpu threads, get 600-680 with scrypt, rad 7970. Cpu threads must be irrelevant, surely.

You bought Alienware.Title: Re: amd radeon 7970m only getting 250khash/s Post by: jtmart007 on April 24, 2013, 07:42:37 PM Watch that laptop doesn't overheat. Laptops are not good miners. I second this. I've had several high perforamnce laptops and they ALWAYS ran at 80c+ when gaming and that's not under full load. I understand mobile chips are meant to have a higher heat tolerance and the 7-series runs cooler but my my I do hope you don't ruin 2 amazing mobile GPUs. |
