I have heard of poeple breaking the 1000K/h point with the R9 290X cards.

[GN545]

Can anyone show proof? I would donate coin for someone who can show proof of this, and help get mine working, across (4) cards in one PC.

I am getting 800+ Kh/s across (4) R9 290X cards (3.2M/h with 3200+WU) in a standard server case.

Attached are pictures of my results after countless hours of tweaking. You can see the time stamps, device manager showing the cards, and the fact that mining is working to the wallet. I solo mine, so there is no shares or anything like that. This is in a standard server case and stays below 85C on all boards. I have been able to get up to 900+K/h on one card, but never with 4 in the machine at once.

If anyone has proof of this working, please let me know.

Thanks,

-Greg

What brand of card are you using?

I have a R9 290 (not a 290X) and I get 831 K/hs, which seems to be more than your more expensive and more power hungry 290x. Something must not be right with your configuration.

Are you sure you have a powerful enough PSU? How many watts?

Try going to https://litecoin.info/Mining_hardware_comparison and find your model, then use the settings next to it. Hope that helps.

I think 1000 is pushing it.

I currently have 2 AMD Sapphire r9 290x and they average 870-880Kh/s.

What brand of card is it?

I'm running on Ubuntu.

AMD Radeon R9 290X
Are you running (4) cards or just one?

[krida]

you must do pushing with cooling fans

GreenTea, what are you getting for WU on the (2) Sapphire cards?

@OP Solo mining is interesting because there is no shares or anything like that.

I have a pair of 290x's both pulling 950-960Kh/s.

Current settings below, 1k per card should be obtainable when more memory arrives, currently at 4gb which sticks me at 27k thread-conc (any more gives error -4). I also have 2 more cards going in when the risers arrive.

Code:

“intensity” : “20",
“worksize” : “512",
“lookup-gap” : “2",
“thread-concurrency” : “27000",
“gpu-engine” : “1000",
“gpu-memclock” : “1500",
“gpu-powertune” : “20"
