Posting this result because i see people selling configs. Put you out of biz! So, for all the 280x owners out there.... Cards: 4 x MSI GAMING 280x LOCKED VOLTSBoard: ASUS M5A99FX PRO R2.0 (3 up on powered risers, 1 down in board) PSU: SilverStone 1500w "Strider" series. Ram: 8GB Card Settings: Stock volts / Clocks: 1168 / 1500 Bios:  Software Platform: Win7 x64 / Cat. 13.4s + 2.9 APP SDK / SGMiner 4.0.0 + Optimized .bin 8192 + CGWatcher. I am not using the optimized .cl file.SGMiner code: --no-submit-stale --thread-concurrency 8192 --gpu-fan 90 --intensity 13 -w 256 -g 2 --api-listen --api-allow 127.0.0.1 --gpu-engine 1168 --gpu-memclock 1500 --gpu-powertune 20 --lookup-gap 2 A note about the config and screenshot: You must include --lookup-gap 2 / -w 256 for the optimized bin to work. The TC must also match as well in your config (or else sgminer will not use the optimized one). The WUs are not stabilized but they will even out to apx 93% of the aggregate hashrate per card. YMWV on the clockrates. These MSI cards are volt-locked. Power: 1365w from the wall (on a 1500w PSU). Minus ~140w idle from the system, ~1300 for the 4 cards = 325w per card. Screencap: |

is it these cards you've got?
R9280XGAMING-3G
They're great hash rates for a 280x!

wow dude that's impressive for 280x especially without having to go crazy on the memclock. did you try modding the voltage in the bios with vbe7? although you probably wouldn't want to, you definitely found the sweet spot. dude you just made my day  do you get the same results with cgminer as sgminer? |

CGMiner + the optimized bin would not go over 760-770khs on any of the 4 cards. At this point, i am quite convinced that SGMiner scales in performance far more efficiently with increased clock rates than with CGMiner. It was the same story with my 13 7950s. i went from ~9.5mhs to ~10.4mhs with SGMiner + optimized 24k bin over CGMiner 2.11.4 + optimized 24k bin. I am not using the optimized .cl file either. You could say i made my day too. ;-) Cheers |

nice hash rates /envy. I have two of those cards, however they seem to start to lose hash at 1090/1500 (753kh)
I'm also using sgminer + 8192.bin

Which OS / driver + SDK combo? Same bios rev as my cards? |

win7 x64, 13-12 drivers. I didn't think of checking the bios. My cards are Elpida. Yours?
Let me get back at ya

Any idea on the power pull of each of those cards?
Great setup!

picked up a X77 bios and flashed. It seems that anything above 1090gpu and my hash rate goes down significantly

I am about to throw the killerwatt on it after this smartcoin launch, so i'll be updating this thread with those power numbers then. |

For scrypt coins it's usually magic numbers. 1080-1500 for ex can be fast then one number in either direction is significant drop. |

Gazza1, true that. I'm guessing the OP got some nice Hynix cards or something  |

Can you please show us the hashrate after it has stabilized (not after 4 min)?
