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.
