Cards can be clocked up another 130 kh/s each for a total of 5280 kh/s I dont like running them that hot, since I'm always out of town working.  Rig is mining dodge coins currently, has been running less then a week.

Currently running  6 Asus R9 280x, all on powered risers, H81 Pro BTC motherboard,  2 800 watt psus, and custom aluminum frame that I built.  I will ship internationally, based on interest, this will include a hard drive and windows 7.   

I'm currently working out of town, if you are interested PM me, I will be back in town in the next 2 weeks ;D >:( :-X


Thanks

I'd love to hear how its possible to get these cards up to 880 KH/S. 
I don't think that's possible.

I'm also pretty sceptical that you can run 6 of these on 1600W.

880kh for a 280x? 

I have 6 rigs running 4.5mh with 6 sapphire toxic 280x supposedly the best 280x you can buy that max out at 810kh/s each but the wattage is ridiculous. I am running them stable at 750-760kh/s now and I'm using about 16-1700watts. So what op is saying is impossible. I know this for a fact.

pics or it never happened. at least 5mins in too so we can see the stability

I'm out of town, I tried it when I was home briefly but like I said' Its from reddit, and I'm not 100% confident and don't wanna do it.  If you work at the bank, and have a in town life, that's great, that would be way better, but I dont want to come back to a burnt down house lol  :o :( ::)

2 points:

first: 1162/1825 is crazy high and could possibly melt your house down.
second: no pic, so it likely never happened.

It's crazy high, but not out of the realm of possibility. I ran my toxics at 1150/1800 for a while when they were 2-3 to a rig. That's about 810KH/s ea. I have 5 to a rig now, and I have to keep them down clocked because of the heat they throw off. Still getting 783KH/s each, and that's undervolted.  ;)

That said, 880KH/s ain't gonna happen unless you've got some ungodly kernel, and mint GPUs.

Sorry but how undervolted are we talking? What are your settings and do you know how much power u are drawing at 780kh/s?

Anyone else notice this guy is mining "dodge" coins...

I didnt even notice, but glad you brought it up.  Its good for the lulz.
