Title: Ausus R9 280x DC2 - 730 Kh - Can more? Post by: gyga800 on January 19, 2014, 01:18:16 AM Hi, I have the Asus R9 280x DC2 and I get 730Kh with this configuration:
setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer.exe --scrypt -o stratum+tcp://xxxxxxx:3333 -u xxxxxxxx -p xxxxxxxx -I 13 -g 2 -v 1 -w 256 --lookup-gap 2 --shaders 2048 --thread-concurrency 8192 --auto-fan --temp-cutoff 90 --temp-overheat 85 --temp-target 70 --gpu-memclock 1500 --gpu-engine 1060 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale --failover-only I can get more power?

Then on the cgminer window, press g, select and increase 10 Mhz on [e]ngine. Do this multiple times until the hashrate drops. Go back a bit and then use that value that gives you the best hashrate Then do the same again, but using -I 20 -g 1 --thread-concurrency 24000 Title: Re: Ausus R9 280x DC2 - 730 Kh - Can more?

Ty Its already very good that you get 730kh, if you push it further your temperature might hit 90-100c.. Title: Re: Ausus R9 280x DC2 - 730 Kh - Can more?

Ty Its already very good that you get 730kh, if you push it further your temperature might hit 90-100c.. Yeah I would have to agree. I have the Gigabyte r9 280x and get 700-720Kh out but run at 76C-81C Title: Re: Ausus R9 280x DC2 - 730 Kh - Can more?

Post by: dragonmike on January 20, 2014, 02:44:57 PM I have R9 DC2T 3GD5's and they run at 755. Relevant settings are:
-I 13 -g2 -w256 --thread-concurrency 8192 --gpu-memclock 1500 --gpu-engine 1085 NB: I haven't specified any higher lookup gap. Shaders are not necessary if you specify TC. Title: Re: Ausus R9 280x DC2 - 730 Kh - Can more? Post by: bjalbert on January 20, 2014, 07:41:55 PM I have 3 of these cards and get about 755-760 khash with core set to 1092 but it varies try anything from 1080-1100 and keep mem at 1500.
On a side note I OC'd one to 1150 core and 1800 mem to get 800 khash but I couldn't keep it cool and was at 1.3V Title: Re: Ausus R9 280x DC2 - 730 Kh - Can more?

Ty Its already very good that you get 730kh, if you push it further your temperature might hit 90-100c.. The temperature is 67-71 all time. everything below 80C is gold everything above 85C ist bad bad bad. The cooler your GPU the longer it lives but never run your fan at 100% because of damaging the fan engine. add ---auto-fan --temp-target 77 --temp-cutoff 82 when you are overclocking you can set higher values but dont forget the 85C rule :) Title: Re: Ausus R9 280x DC2 - 730 Kh - Can more? Post by: blade007 on February 04, 2014, 03:59:02 PM I just got 3 of these and I set up one to test with and I can only get 670Kh. I am using Guiminer. I have never used cg miner and don't know where to start. I would love to get 700Kh.
I have my gpu clocked @1030 and memory at 1500 and GPU treads in guiminer @2 |
