5x 280x, AMD Driver 16.9.2, Win 10 x64

I can't get any options to work besides -c, -u, -p and -g.  Using -g makes miner run really slow.

My issue is crashing graphics driver.  Solution seems to be using -i from what im reading but i get unrecognised command for -i and the others listed.  Anyone else having this problem?  Drivers crash one by one every few minutes of mining.

Processor is an AMD Sempron 145.  I know it is slow but didn't think anything faster was needed when graphics cards are doing the mining.  Was also trying to not use as much electricity with this processor.  Anyway, so I need a faster processor?  Is that my problem...maybe?  Motherboard is GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX + SB950 SATA 6Gb/s USB 3.0 ATX AMD.

Thanks guys!
