K, I checked my settings and am getting 740 kh/s with these. I'm using sgminer 4.1.0 and I have the powercolor 280x 3GBD5-T2DHE/OC model. I've undervolted them to 1.1 v.
--intensity 13 -w 256 -g 2 --thread-concurrency 8192 --auto-fan --temp-target 65 -w 256 --gpu-engine 1045 --gpu-memclock 1500 --gpu-powertune 0 -k zuikkis
Couple of questions for you:
- what drivers are you using?
- are you deleting the .bin files?
- powered risers?
- when I had cards that came up with something like 25 kh/s, I found it best to go into computer management and delete the card, reboot and let it load the driver again and reboot. That typically solved that issue.
good luck...

did you undervolt down to 1.1v. I wasn't able to get to "thread-concurrency" : "20800", until then. Hashrate didn't change much between 11200 and 20800.
Try backing down the "thread-concurrency" by multiples of 64 and see if that helps
Glad you could get to 700khs. i was fighting it for a while too.

I have 8 of these cards running happily at 740 khash on windows. When I get home I will post what I did.
OK these settings got me to 700khs, first time I ever seen that without shutting down thew pc, only problem is it only mines o one card the other one is there doing nothing at 25khs, why aren't both cards hashing away?

Is your PSU strong enough for sure? Normally only the driver should crash if a setting is wrong/overclock too high/voltage too low.
BTW: My 280x hashes happily up to 95°C (forgot to set fan speed once), no throttling.

I have 1000w powering 2 cards, and another 1000W powering 3 cards, Its a 80plus from novatech they are very good quality power supplies, but to be fair I have wondered a few times already if in fact that is the problem, but rather not believe it coz just bought these psus 2 weeks ago.

I also have these cards, have finally got them running stable @ 1.1v ~720Kh/s
Using almost the same settings as in your post, however I found that these cards don't like anything over 1050 GPU engine

I already tried those settings with same voltage, pc shuts down after 2 min mining.
Thanks

also "thread-concurrency" : "20800", was at 11200 prior to undervolting
Here are my settings for my powercolor R9 280x. I have also set the voltage set at 1.1v
Was getting 715+Kh/s prior to setting voltage lower but temps were always running high.
Lowered the voltage to 1.1v and now fans run about 40% at 70c and get 710Kh/s and a lot less power at the wall.

If that works I will surely tip you mate. I post later on to let you know what happened with those settings.

Hello fellow miners.
I wonder if someone can point me in the right direction coz I have white hair from the past 2 weeks trying to figure this out, so now I decided to cry for help.
I have 5 of these gpus but unfortunately I can't hash more than 580 khs.
I have literately tried every single guide available for these cards and none of them help my case.
I believe the problem is when I add -g 2, because the comp always goes off when I do that, if I remove the -g 2 it works at 580 khs but that's as far as it goes.
This is my bat. currently:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
--intensity 13 -w 256 -g 1 --lookup-gap 2 --thread-concurrency 8192 --temp-target 70 --auto-fan --gpu-engine 1090 --gpu-memclock 1500
I have also tried intensity at 20,19,18, and comp always shuts down when I do that.
I am using the latest sgminer with the latest catalyst drivers, also tried, bf and cgminer same results. My system is windows 7 ultimate.
What about -g 2 with a lower clockrate?I wonder if someone can point me in the right direction coz I have white hair from the past 2 weeks trying to figure this out, so now I decided to cry for help.

Also try 1350 MHz memory and report your results.
Silly me never thought about lower the clock, thanks for that mate!
I have now tried that, first time in -g 2 that did not shut down the pc, so think I have to work my way up from 1350 coz khs now is only 506.
I went with this set up this time
--intensity 13 -w 256 -g 2 --lookup-gap 2 --thread-concurrency 8192 --temp-target 65 --auto-fan --gpu-engine 1030 --gpu-memclock 1350
You need to find your sweet spot of core to memory ratio - it won't be the default speed, and it'll be different for every card. I just used CCC to overclock. You also want to be running at intensity 13. Temp target is too high - the 280X throttles around 70C. These are based on a 7950, but they are not the same! I've mine set to 65C temp target.
I had serious issues getting my R9 280X working, I was only getting about 580kH with mine. In a last ditch attempt downloaded GUIMiner-scrypt, set it up so it produced a batch file, which I use to run cgminer 3.7.2 - I now get 710-715kH. It's default settings for the 280X work well, and once I tweaked the sweet spot, it worked a treat.

I will try that GUIMiner-scrypt, always heard bad reviews about it so never looked into it but if it works it's all I care.
