Ausus R9 280x DC2 - 730 Kh - Can more?

[gyga800]

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?

Increase the --gpu-memclock to 1750 or 1800, then increase --gpu-engine accordingly.

--gpu-engine accordingly. ??

Yes. Start at ~55% of the memory clock, for example --gpu-engine 950 and --gpu-memclock 1750.

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

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

The temperature is 67-71 all time.

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.

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

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

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
