I'll experiment with mine if I get some spare time and get back to you.
This is for yacoin, right?
Make sure you get thirtybird's updated yacminer build.

Oh forgot LG! lg 8...Close to 4kh/s with a mild oc. I'm folding right now, curecoin where it's at for miners. (or yacoin  but I prefer to buy atm) |

Not really...the 280x isn't too far behind, and neither is a gtx 750 ti at 3.5kh/s.

any experience with 290x ?
I cannot get it to work properly for YAC's higher n-factor. We get too many HW errors (more than accepted shares)
Works superb with MRC's 11 N factor, but for YAC we cannot get it right.

Try any of these settings: --buffer-size 3712 --lookup-gap 4 -R 3712 -g 1 -w 256 or --buffer-size 3712 --lookup-gap 8 -R 7424 -g 1 -w 256 Start from there and move up or down the -R value in 64 increments till you get 0 HW. |

N-factor change today. Do I have to change my settings for the r7 240 4GB, are there some new magical settings?

Can someone please post parameters for R7 240 4GB at N=15 ?
I can not get it over 820h/s without hardware errors.

Now that the Nfactor is over 14 I've tried experimenting with lower nfactor coins (ultra, micro, bdc) and nothing really looks that profitable with a R7 240 @ 2GB of ram...anyone got any suggestions on what they would do?

can you not read back LITTERALLY three posts from yours? I tried that trom ivanlabrie and it crashed my driver. But it works with lookup gap raised to 3 (3 posts back, as you stated). I got 1Kh with this: --buffer-size 3712 --lookup-gap 3 -R 4992 -g 1 -w 256 Thanks. |

Yeah, I'm doing something like that but I still get the odd hw...meh.
I'm back to folding for now, might get back into yacoin if I figure it out but for now I don't have time to tweak it sadly.

Maybe ZCC or YBC. My R7 250 2 GB are still on YAC. Not as effective, but no worse off than any other 2 GB card --buffer-size 3712 --lookup-gap 3 -R 4992 -g 1 -w 256
Set your R to 1280 - you want R to be 4 time the number of shaders on the card. Hashrate goes down if it's in excess of 4x unless its an even multiple of 4x the number of shaders (2560 gives the same hash rate as 1280 - it's pretty weird) |
